Best Easy Pumpkin Snickerdoodle Blondies with Brown Butter Icing

I burned the first batch of these pumpkin snickerdoodle blondies so badly that my smoke detector has never quite recovered. The sugar crystallized into a weird, crackly mess on top while the middle stayed raw, and I stood there with the oven door open, spatula in hand, wondering why I thought combining pumpkin and brown butter was a good idea. It wasn’t even close to edible, but something about that burnt, nutty smell stuck with me, and I knew I had to figure it out.

See, I have this thing about fall baking that borders on obsessive. Once the weather turns cool enough for a sweater, I start craving those warm spices and rich, buttery desserts that make the house smell like a bakery. Pumpkin snickerdoodle blondies seemed like the perfect hybrid, all the chew of a blondie with that classic cinnamon-sugar crust, plus pumpkin to keep them soft. But pumpkin has all this water in it, and brown butter has those milk solids that burn if you look at them wrong. My first attempt was a disaster, but honestly, it taught me more than any perfect batch ever could.

After three more tries and a lot of scribbled notes, I finally cracked the code. The trick is browning the butter just right, then letting it cool before mixing, and blotting the pumpkin puree with paper towels to remove some of that moisture. It sounds fussy, but it makes all the difference. These blondies come out thick, chewy around the edges, and impossibly tender in the middle, with that signature snickerdoodle tang from cream of tartar and a brown butter icing that seeps into every crack. They taste like autumn in bar form.

I bring these to every fall gathering now, and they disappear faster than anything else on the table. One bite and people get that quiet look, like they are trying to figure out how something this simple tastes so good. That is the kind of recipe I want to share.

Why You Will Love This Recipe

These pumpkin snickerdoodle blondies are the fall dessert you will make on repeat, and here is why they work so well.

• Quick & Easy: From start to finish, these blondies take about 35 minutes. No stand mixer needed, no chilling the dough, just one bowl and a whisk.
• Simple Ingredients: You probably have most of this in your pantry already. Pumpkin puree, butter, sugar, flour, and cinnamon. Nothing weird or hard to find.
• Perfect for Fall Gatherings: Whether it is a Halloween party, Thanksgiving potluck, or just a cozy Sunday afternoon, these blondies fit right in. They travel well and stay soft for days.
• Crowd-Pleaser: Kids love the snickerdoodle flavor, and adults go crazy for that brown butter icing. I have yet to meet someone who turns one down.
• Unbelievably Delicious: The combination of pumpkin, brown butter, and cinnamon sugar is pure comfort. The edges are slightly crisp, the middle is tender, and that icing takes it over the top.

What makes these different from other pumpkin bars is the texture. Most pumpkin desserts are cakey or dense, but these blondies have that perfect chew, like a really good cookie bar. The brown butter adds a nutty, caramelized depth that regular butter just cannot match, and the cream of tartar gives that classic snickerdoodle tang that cuts through the sweetness. It is not just another pumpkin recipe, it is the one you will actually want to make again.

I tested this recipe six times to get the proportions right. Too much pumpkin and they get gummy. Too much brown butter and they spread flat. This version is the Goldilocks of blondies, and I am pretty proud of it.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients that come together to create something truly special. Each one plays a specific role in the texture and flavor.

For the Blondies

• Unsalted butter, 10 tablespoons (141g) – You will brown this yourself, which sounds fancy but is dead simple. I use Land O Lakes because it browns evenly, but any quality brand works.
• Light brown sugar, 1 cup (200g), packed – Brown sugar adds moisture and that deep, molasses flavor that pairs perfectly with pumpkin. Dark brown sugar works too, but the blondies will be slightly darker and more caramel-like.
• Granulated sugar, 1/4 cup (50g) – A little white sugar helps with the structure and keeps the blondies from being too dense.
• Large egg, 1, at room temperature – Room temperature egg incorporates into the butter mixture more smoothly. If you forget to set it out, place it in a bowl of warm water for 5 minutes.
• Pumpkin puree, 1/2 cup (120g) – Not pumpkin pie filling. Make sure it is 100% pure pumpkin. Libby’s is my go-to because it is consistently thick and not watery. Pat it dry with a paper towel before measuring to remove excess moisture.
• Vanilla extract, 1 teaspoon – Pure vanilla extract makes a difference here. Imitation vanilla works in a pinch, but the flavor is not as warm and rich.
• All-purpose flour, 1 and 1/2 cups (188g) – Spoon and level your flour. Scooping directly from the bag packs in too much and makes the blondies dry.
• Cream of tartar, 1 teaspoon – This is the secret ingredient that gives snickerdoodles their signature tang. Do not skip it. You can substitute with 2 teaspoons of lemon juice or white vinegar in a pinch, but cream of tartar is better.
• Baking soda, 1/2 teaspoon – Helps the blondies rise just a little and keeps them tender.
• Ground cinnamon, 1 and 1/2 teaspoons – The star spice here. I use McCormick because it is reliable and fragrant.
• Ground nutmeg, 1/4 teaspoon – Adds warmth. Freshly grated nutmeg is amazing if you have it, but pre-ground works fine.
• Ground ginger, 1/4 teaspoon – A little kick of warmth that complements the pumpkin.
• Salt, 1/2 teaspoon – Balances the sweetness and enhances all the flavors. I use fine sea salt.

For the Cinnamon-Sugar Topping

• Granulated sugar, 2 tablespoons
• Ground cinnamon, 1 teaspoon

For the Brown Butter Icing

• Unsalted butter, 3 tablespoons (42g) – You will brown this too, so keep an eye on it.
• Powdered sugar, 1 cup (120g) – Sift it if it is lumpy to avoid a grainy icing.
• Milk, 2 to 3 tablespoons – Whole milk gives the richest texture, but any milk works. Start with 2 tablespoons and add more if needed.
• Vanilla extract, 1/2 teaspoon
• Salt, a pinch – Trust me on this. It makes the icing taste more complex.

Equipment Needed

You do not need a fancy kitchen to make these blondies, which is one of the reasons I love this recipe.

• 8×8-inch baking pan – Metal pans work best for even browning. Glass pans work too, but the blondies might take a few extra minutes to bake through.
• Parchment paper – Line the pan with parchment, leaving overhang on two sides. This makes lifting the blondies out so much easier.
• Light-colored saucepan – A light-colored pan helps you see the butter change color as it browns. Dark pans make it hard to tell when it is done.
• Mixing bowls – One medium bowl for the wet ingredients and one for the dry.
• Whisk – A good whisk is all you need. No electric mixer required.
• Rubber spatula – For folding the dry ingredients into the wet and scraping every last bit of batter into the pan.
• Cooling rack – Lets air circulate around the pan so the blondies cool evenly.

If you do not have a light-colored saucepan, just use what you have and watch the butter carefully. I have burned brown butter in a dark pan more times than I care to admit. Also, a kitchen scale is helpful for measuring the butter and flour, but measuring cups work fine.

Preparation Method

Let me walk you through this step by step. I have included all the little details that I wish someone had told me the first time.

1. Preheat and prep the pan. Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving about 2 inches of overhang on two opposite sides. This creates handles for lifting the blondies out later. Lightly spray the parchment with nonstick spray just to be safe.
2. Brown the butter. Place 10 tablespoons of unsalted butter in a light-colored saucepan over medium heat. Stir constantly with a rubber spatula or wooden spoon. The butter will melt, then foam, then start to crackle and pop. After a few minutes, the foam will subside and you will see brown specks form at the bottom of the pan. This is the milk solids toasting. The butter will smell nutty and amazing. As soon as it turns a golden amber color, remove it from the heat and pour it into a heatproof bowl to stop the cooking. Let it cool for 10 to 15 minutes. Do not walk away from the butter while it browns. It goes from perfect to burnt in about 30 seconds.
3. Pat the pumpkin dry. While the butter cools, measure 1/2 cup of pumpkin puree and spread it on a plate lined with a paper towel. Place another paper towel on top and press gently to absorb excess moisture. This step is crucial. Pumpkin holds a lot of water, and if you do not remove some of it, the blondies will be gummy. Let it sit while you mix the batter.
4. Mix the wet ingredients. In a medium bowl, whisk together the cooled brown butter, 1 cup packed light brown sugar, and 1/4 cup granulated sugar until smooth and combined. It should look like wet sand. Add the room temperature egg and whisk vigorously until the mixture is thick and glossy, about 1 minute. Add the pumpkin puree and 1 teaspoon vanilla extract and whisk until smooth. The batter will look slightly separated at this point, that is normal.
5. Mix the dry ingredients. In a separate bowl, whisk together 1 and 1/2 cups all-purpose flour, 1 teaspoon cream of tartar, 1/2 teaspoon baking soda, 1 and 1/2 teaspoons cinnamon, 1/4 teaspoon nutmeg, 1/4 teaspoon ginger, and 1/2 teaspoon salt. Make sure everything is evenly distributed.
6. Combine wet and dry. Pour the dry ingredients into the wet ingredients and fold together with a rubber spatula until just combined. Do not overmix. A few streaks of flour are okay. Overmixing develops the gluten and makes the blondies tough. The batter will be thick and slightly sticky.
7. Make the cinnamon-sugar topping. In a small bowl, stir together 2 tablespoons granulated sugar and 1 teaspoon cinnamon.
8. Assemble the blondies. Spread the batter evenly into the prepared pan. It is thick, so use the spatula to press it into the corners. Sprinkle the cinnamon-sugar mixture evenly over the top. Do not press it in, let it sit on top where it will form that classic snickerdoodle crust.
9. Bake. Bake for 22 to 26 minutes, or until the edges are golden brown and the center looks set but still slightly soft. A toothpick inserted into the center should come out with a few moist crumbs, not wet batter. The top will look crackly and the kitchen will smell incredible. Let the blondies cool in the pan on a wire rack for at least 20 minutes before icing.
10. Make the brown butter icing. While the blondies cool, place 3 tablespoons of unsalted butter in the same saucepan you used earlier. Brown it the same way, over medium heat, stirring constantly. Once it turns amber and smells nutty, remove it from the heat. Let it cool for 2 minutes, then whisk in 1 cup powdered sugar, 2 tablespoons milk, 1/2 teaspoon vanilla, and a pinch of salt. Whisk until smooth. If the icing is too thick, add the remaining tablespoon of milk. If it is too thin, add a little more powdered sugar. Drizzle the icing over the warm blondies. Use the back of a spoon to spread it evenly if needed.
11. Cool completely. Let the blondies cool completely in the pan before slicing. This gives the icing time to set. If you slice them while they are warm, the icing will run everywhere. I speak from experience. Once cool, use the parchment handles to lift the blondies out and slice them into 9 or 16 squares, depending on how generous you are feeling.

Cooking Tips & Techniques

I have made these pumpkin snickerdoodle blondies more times than I can count, and I have learned a few things along the way.

The brown butter is the most important part. Do not rush it. If you take it off the heat too early, you will not get that nutty flavor. If you take it off too late, it will be bitter and burnt. Watch for the milk solids to turn a deep amber color and smell for that unmistakable nutty aroma. I once got distracted by a phone call and ended up with black butter. The blondies were not salvageable.

Patting the pumpkin dry feels fussy, but it is the difference between a blondie and a pumpkin brick. Pumpkin puree is about 90% water, and that water steams during baking, creating a gummy texture. Removing just a little bit of moisture concentrates the flavor and keeps the texture chewy. I learned this trick from a pastry chef friend, and it changed everything.

Do not overmix the batter. I know it is tempting to keep stirring until it looks perfectly smooth, but that develops gluten and makes the blondies tough. Fold just until the flour disappears. A few lumps are fine.

Let the blondies cool before slicing. I know the smell is intoxicating and you want to dig in immediately, but warm blondies are fragile. The icing will slide right off and the bars will crumble. Patience pays off here. I usually make these in the morning so they are ready by afternoon.

If you want cleaner slices, chill the blondies in the fridge for 30 minutes before cutting. Use a sharp knife and wipe it clean between cuts. This gives you those bakery-style edges.

Variations & Adaptations

This recipe is flexible, and I have tried several variations over the years. Here are some of my favorites.

Gluten-Free Version: Substitute the all-purpose flour with a 1-to-1 gluten-free baking flour blend that contains xanthan gum. I have used Bob’s Red Mill with great results. The texture will be slightly more tender, but the flavor is spot on.

Dairy-Free Version: Use a high-quality vegan butter for both the blondies and the icing. Miyoko’s and Earth Balance work well. The brown butter flavor will be slightly different, but still delicious. Use your favorite non-dairy milk in the icing.

Add Mix-Ins: Fold in 1/2 cup of white chocolate chips, chopped pecans, or even butterscotch chips before baking. White chocolate is my personal favorite because it pairs so well with pumpkin and brown butter.

Spice It Up: Add 1/4 teaspoon of ground cloves or allspice to the dry ingredients for a more complex spice profile. You can also swap the cinnamon-sugar topping for a chai spice blend.

Pumpkin-Free Version: You can make these as plain snickerdoodle blondies by omitting the pumpkin and increasing the butter to 12 tablespoons. The texture will be denser and chewier, like a classic blondie.

I once made a version with browned butter pecans folded in, and it was dangerous. I ate half the pan before my husband got home. If you are feeling fancy, toast 1/2 cup of pecans in the oven at 350°F for 5 minutes, chop them, and fold them into the batter.

Serving & Storage Suggestions

These blondies are best served at room temperature, but they are also amazing slightly warm with a scoop of vanilla ice cream. The contrast between the warm, gooey blondie and the cold, creamy ice cream is pure fall comfort.

For a Halloween party, I cut them into small squares and arrange them on a platter with some of my candy corn rice krispie treats and a few Halloween sugar cookies. It makes for a beautiful, festive dessert table that everyone loves.

They also pair beautifully with a warm drink. A pumpkin chai latte or a pumpkin spice cold brew are my go-to choices. The spices in the drink complement the blondies perfectly.

Storage: Store leftover blondies in an airtight container at room temperature for up to 4 days. Place a sheet of parchment paper between layers if stacking them. They will stay soft and chewy.

Freezing: These blondies freeze beautifully. Wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag or container. Freeze for up to 3 months. Thaw at room temperature for about 30 minutes, or warm them in the microwave for 15 seconds for that fresh-baked taste.

Reheating: For a quick treat, microwave a blondie for 10 to 15 seconds. The icing will get slightly melty and the blondie will be soft and warm. Do not overheat or the icing will melt completely.

The flavors actually develop over time. Day two is often better than day one, as the brown butter and spices have time to meld together. If you can resist eating them all immediately, you will be rewarded.

Frequently Asked Questions

Can I use pumpkin pie filling instead of pumpkin puree?

No, do not do that. Pumpkin pie filling is already sweetened and spiced, which will throw off the sugar and spice balance in this recipe. Stick with 100% pure pumpkin puree. Libby’s is my go-to brand.

Why did my blondies turn out gummy?

Gummy blondies usually mean too much moisture. Make sure you pat the pumpkin puree dry with paper towels before adding it to the batter. Also, check your oven temperature with an oven thermometer. An oven that runs too cool can cause the blondies to steam instead of bake.

Can I make these ahead of time?

Absolutely. These blondies actually taste better the next day after the flavors have had time to meld. Bake them a day ahead, let them cool completely, and store them in an airtight container at room temperature. Ice them just before serving for the prettiest presentation.

Do I have to use cream of tartar?

Cream of tartar gives snickerdoodles their signature tang and helps with the texture. If you do not have it, you can substitute with 2 teaspoons of lemon juice or white vinegar, but the flavor will be slightly different. The blondies will still be delicious, just not as tangy.

Can I double this recipe?

Yes, you can double the recipe and bake it in a 9×13-inch pan. Increase the baking time to about 28 to 32 minutes. Keep an eye on the edges, they should be golden brown and the center should look set. The brown butter icing recipe can be doubled as well.
