Ingredients

Steps

  • 1
    Heat oven to 350°F. Grease or spray two 8-inch round cake pans; place 8-inch round piece of cooking parchment paper in bottom of each pan. Grease or spray parchment paper. In large bowl, beat 1 box cake mix and ingredients called for on box with electric mixer on low speed 30 seconds, then on high speed about 2 minutes or until smooth. Spread in pans. Bake as directed on box. Cool 10 minutes; run knife around sides of pans to loosen cakes. Gently remove from pans to cooling rack; remove parchment paper. Cool completely, about 30 minutes. Meanwhile, repeat to make 2 more layers.
  • 2
    Flatten cake layers by trimming off rounded tops. In 2 layers, cut small round out of center, using 4-inch round cutter.
  • 3
    To assemble cake: Place 1 uncut cake layer on cake stand or serving platter; spread 1/3 cup frosting on top. Top with 1 layer with center removed; spread 1/3 cup frosting on top. Top with second layer with center removed; spread 1/3 cup frosting on top.
  • 4
    Fill cake with candies and candy sprinkles. Gently press candies to level; top with full cake layer. Frost side and top of cake with remaining frosting.

Tips from the Betty Crocker Kitchens

  • tip 1
    Don’t have a 4-inch round cutter for this rainbow surprise cake recipe? Cut out a 4-inch circle of cooking parchment paper and use it as a pattern.
  • tip 2
    Be sure to cool cake pans completely, then wash, dry and spray with cooking spray before baking the second cake mix.
  • tip 3
    To pipe frosting mounds on top of your rainbow surprise cake, tint some of the frosting with gel food color to desired color. Fit a decorating bag with 1/2-inch round piping tip and fill with tinted frosting. Pipe frosting mounds around top edge of cake.
