Ingredients
1 box (15.25 oz) yellow cake mix
1/2 cup unsalted butter, melted
2 large eggs
1 teaspoon vanilla extract
1 cup semi-sweet chocolate chips
1/4 cup rainbow sprinkles
1 to 2 tablespoons milk (if needed)
1/2 cup unsalted butter
1 1/2 cups powdered sugar
1/4 cup cocoa powder
1 to 2 tablespoons milk
1/2 teaspoon vanilla extract
Instructions
1. Preheat oven to 350°F (175°C) and line a 9-inch round cake pan with parchment paper. Lightly grease the sides.
2. In a large mixing bowl, combine the cake mix, melted butter, eggs, and vanilla extract. Mix until just combined. If the dough is too dry, add milk one tablespoon at a time.
3. Fold in the chocolate chips and rainbow sprinkles using a spatula.
4. Press the dough evenly into the prepared pan and smooth out the top.
5. Bake for 20–25 minutes, or until the edges are golden and the center is just set.
6. Allow the cookie cake to cool completely in the pan.
7. While cooling, prepare the frosting: Beat the butter until fluffy, then add powdered sugar, cocoa powder, milk, and vanilla. Beat until smooth.
8. Once cooled, pipe the frosting around the edges of the cookie cake and top with extra sprinkles.
9. Slice and serve!
Notes
Don’t overbake! The center should be just set to keep it soft and chewy.
Always cool completely before adding frosting to prevent melting.
You can easily swap cake mix flavors or use different mix-ins like M&Ms, toffee bits, or chopped nuts.
