Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 cup (227 g) unsalted butter, softened
  • ¾ cup (150 g) granulated sugar
  • ¾ cup (165 g) packed brown sugar
  • 2 large eggs, room temperature
  • 2 tsp pure vanilla extract
  • 1 ½ cups (270 g) chocolate chips or chunks (optional)
  • ½ cup (113 g) unsalted butter, softened (for frosting)
  • 3–4 cups (360–480 g) powdered sugar, sifted
  • 2–3 tbsp (30–45 ml) whole milk or heavy cream
  • 1 tsp pure vanilla extract (for frosting)
  • Gel food coloring in school colors (red, blue, green, etc.)

Instructions

  1. Preheat your oven to 350°F (175°C). Line your baking sheet or pan with parchment paper.
  2. Whisk dry ingredients: In a medium bowl, mix 2 ½ cups all-purpose flour, 1 tsp baking soda, and ½ tsp salt. Set aside.
  3. Cream butter and sugars: In a mixing bowl, beat 1 cup softened unsalted butter with ¾ cup granulated sugar and ¾ cup packed brown sugar until light and fluffy (3-4 minutes).
  4. Add eggs and vanilla: Beat in 2 large eggs, one at a time, then stir in 2 tsp vanilla extract until smooth and creamy.
  5. Combine wet and dry: Gradually add dry ingredients to wet, mixing on low speed until just combined. Avoid overmixing.
  6. Fold in chocolate chips gently.
  7. Shape the cookie cake: Transfer dough onto lined baking sheet or pan. Spread evenly into a 12-inch round shape, patting edges slightly thinner.
  8. Bake for 25-30 minutes until edges are golden brown and center is slightly soft.
  9. Cool completely on the baking sheet for at least 30 minutes before frosting.
  10. Make frosting: Beat ½ cup softened unsalted butter until creamy. Gradually add 3-4 cups sifted powdered sugar, alternating with 2-3 tbsp milk or cream, until smooth and spreadable. Stir in 1 tsp vanilla extract.
  11. Divide frosting into bowls and tint with gel food coloring to match school colors.
  12. Decorate: Spread a base layer of frosting, then pipe vibrant colors using piping bags and tips in desired patterns.
  13. Chill briefly if needed to set frosting. Serve at room temperature.

Notes

Use gel food coloring to prevent runny frosting. Soften butter to cream properly. Check cookie at 25 minutes to avoid overbaking. If frosting is too stiff, add milk; if too runny, add powdered sugar. Chill frosting briefly if it softens too much before serving.
