Ingredients

Scale
  • 1 cup (226g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 cup (220g) packed light brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 3 cups (375g) all-purpose flour (or almond flour for gluten-free)
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 1 cup (150g) rainbow sprinkles (jimmies or non-melting recommended)
  • 1 cup (230g) unsalted butter, softened (for frosting)
  • 4 cups (480g) powdered sugar, sifted
  • 23 tablespoons whole milk or heavy cream (or dairy-free milk)
  • 1 teaspoon vanilla extract (for frosting)
  • Red gel food coloring
  • Blue gel food coloring
  • White nonpareils or sanding sugar for stars decoration

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9-inch round cake pan and line with parchment paper.
  2. In a large bowl, beat 1 cup softened butter with granulated sugar and brown sugar until creamy and smooth, about 3-4 minutes.
  3. Beat in eggs one at a time, fully incorporating each before adding the next. Stir in vanilla extract.
  4. In a separate bowl, whisk together flour, baking soda, baking powder, and salt. Gradually add to wet mixture, mixing on low speed until just combined. Do not overmix.
  5. Gently fold in rainbow sprinkles with a spatula to avoid color bleeding.
  6. Press dough evenly into prepared pan, smoothing the top.
  7. Bake for 25-30 minutes until edges are golden and a toothpick inserted comes out with a few moist crumbs.
  8. Cool in pan for 15 minutes, then transfer to wire rack to cool completely.
  9. For frosting, beat 1 cup softened butter until creamy. Gradually add powdered sugar alternating with milk until smooth and spreadable. Stir in vanilla extract.
  10. Divide frosting into three bowls. Leave one plain (white), color one with red gel, and one with blue gel food coloring.
  11. Frost the cookie cake: frost one upper corner with white frosting, create red and white stripes on remaining surface, cover the white corner with blue frosting, and sprinkle white nonpareils or sanding sugar on blue area to mimic stars.
  12. Chill decorated cake for at least 30 minutes to set frosting before slicing and serving.

Notes

Use softened butter (not melted) for best dough and frosting texture. Use jimmies or non-melting sprinkles to avoid color bleeding. Frost in sections with an offset spatula for clean edges. Chill the frosted cake before slicing for neat cuts. If overbaked, frosting and sprinkles add moisture back. Use a warm sharp knife to slice if frosting is too firm.
