Ingredients

Scale
  • 2 ½ cups all-purpose flour (315 g)
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 cup unsalted butter, softened (226 g)
  • ¾ cup granulated sugar (150 g)
  • ¾ cup light brown sugar, packed (165 g)
  • 2 large eggs, room temperature
  • 2 tsp pure vanilla extract
  • 1 cup unsalted butter, softened (for frosting) (226 g)
  • 4 cups powdered sugar, sifted (480 g)
  • 23 tbsp whole milk or heavy cream
  • 1 tsp pure vanilla extract (for frosting)
  • Red and blue gel food coloring

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9-inch round cake pan with parchment paper and lightly grease the sides.
  2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat the softened butter with granulated sugar and brown sugar until light and fluffy, about 3-4 minutes.
  4. Beat in the eggs one at a time, then mix in the vanilla extract until fully combined.
  5. Gradually add the dry flour mixture to the wet ingredients, mixing on low speed just until combined. Do not overmix.
  6. Spoon the cookie dough into the prepared pan and press evenly to smooth the top.
  7. Bake for 20-25 minutes until edges are golden brown and the center is just set with a few moist crumbs on a toothpick.
  8. Cool the cookie cake in the pan for 15 minutes, then transfer to a wire rack to cool completely before frosting.
  9. To make the buttercream, beat softened butter on medium speed until creamy, about 2 minutes.
  10. Gradually add powdered sugar, alternating with milk or cream, until smooth and fluffy. Mix in vanilla extract.
  11. Divide frosting into three bowls: leave one white, tint one red, and one blue using gel food coloring.
  12. Spread the white frosting over the entire cooled cookie cake as a base layer.
  13. Pipe or spread a blue square in the top-left corner, then pipe red and white stripes horizontally across the rest of the cookie.
  14. Chill the cookie cake in the refrigerator for 30 minutes to set the frosting before slicing and serving.

Notes

Use softened butter for best mixing results. Do not overmix the dough to avoid toughness. Use gel food coloring for vibrant frosting colors. Chill frosting if too soft before piping. Let cookie cool completely before frosting to prevent melting. If no piping bags, use a zip-top bag with a small corner cut off.
