Step-by-Step Instructions

Step 1: Prepare Colored Cake Layers
Make cake batter as per box instructions. Divide into six bowls, color each differently, and spread into thin layers on parchment-lined trays. Bake and cool completely.

Step 2: Cut Cake Dots
Use a small round cookie cutter (about 1 inch) to cut circles from each colored layer and set aside.

Step 3: Prepare Vanilla Cake Batter
Preheat oven to 350°F (175°C) and grease two 8-inch pans. Whisk flour, baking powder, and salt. Beat butter and sugar until fluffy, then add eggs and vanilla. Alternate adding dry ingredients and milk until smooth.

Step 4: Assemble Dot Layers
Spread a thin layer of vanilla batter in pans. Insert colored cake dots upright in rows, then gently pour remaining batter around them and smooth the tops.

Step 5: Bake the Cake
Bake for 30–35 minutes until a toothpick comes out clean. Cool in pans for 15 minutes, then transfer to wire racks.

Step 6: Make Frosting
Beat butter until creamy. Add powdered sugar gradually, then mix in vanilla, cream, and salt until fluffy.

Step 7: Assemble & Decorate
Layer cakes with frosting, apply a crumb coat, chill for 20 minutes, then finish frosting. Decorate with sprinkles and party toppings.
