Ingredients

Scale
  • 1/2 cup unsalted butter (softened)
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3/4 cup chocolate chips
  • 1/4 cup rainbow sprinkles
  • 1 cup frosting (store-bought or homemade)
  • Extra sprinkles for topping

Instructions

  1. Preheat oven to 350°F (175°C). Grease or line a 9-inch round cake pan.
  2. Cream butter, brown sugar, and granulated sugar until fluffy. Add egg and vanilla, mixing well.
  3. Stir in flour, baking soda, and salt until just combined. Fold in chocolate chips and sprinkles.
  4. Press dough evenly into the prepared pan and smooth the top.
  5. Bake for 20–25 minutes until edges are golden and center is just set. Cool completely.
  6. Pipe frosting along the edge and top with extra sprinkles.
  7. Slice and serve with a glass of milk or your favorite ice cream.

Notes

  • Let the cookie cake cool fully before decorating to avoid melting the frosting.
  • Don’t overmix the dough — stop once combined for a soft texture.
  • Use themed sprinkles to match holidays or party colors.
