Ingredients
Scale
- 1 box Betty Crocker™ Super Moist™ White Cake Mix
- 1 cup buttermilk
- 1/2 cup vegetable oil
- 3 eggs
- 1 tablespoon unsweetened baking cocoa
- 2 teaspoons royal blue paste food color
- 1 toothpickful violet paste food color
- 1 jar (7 oz) marshmallow creme
- 1 cup butter, softened
- 2 1/2 cups powdered sugar
- 1/8 teaspoon salt
Instructions
- Preheat oven to 350°F (or 325°F for dark/nonstick pans). Spray three 8-inch round cake pans with cooking spray and line bottoms with parchment paper.
- In a large bowl, beat the cake mix, buttermilk, oil, eggs, cocoa, and both food colors with an electric mixer on medium speed for 2 minutes. Scrape the bowl as needed.
- Divide batter evenly among the prepared pans.
- Bake for 18–22 minutes or until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then transfer cakes to wire racks and remove parchment paper. Let cool completely, about 45 minutes.
- In a large bowl, beat marshmallow creme and softened butter until smooth. Add powdered sugar and salt; beat on low until fully incorporated and smooth.
- If needed, level two cake layers. Place one layer (top side down) on a serving plate and spread with 1/3 cup frosting. Repeat with second layer. Top with final layer (top side up). Frost the top and sides with remaining frosting.
- Store loosely covered in the refrigerator.
Notes
- Use paste or gel food coloring for a vibrant hue without thinning the batter.
- Cool cakes completely before frosting to prevent melting the buttercream.
- Cake layers can be made ahead and frozen for up to 1 month.
- To ensure even layers, weigh batter when dividing into pans.
- For a clean finish, apply a crumb coat and chill before final frosting layer.
