What goes in: 15 oz white cake mix, 1 cup water, ½ cup oil, 3 egg whites, blue + purple + pink gel coloring, 6.8 oz vanilla pudding mix, 3¾ cups cold milk, 8 oz whipped topping, 2.8 oz unicorn sprinkles
– How it comes together: Mix the cake batter until smooth, divide into three bowls and color each one. Drop spoonfuls into your pan and lightly swirl for that dreamy marble look, then bake until set and let it cool.
Poke holes all over the cake, pour in the creamy pudding so it sinks into every bite, then spread the rest on top. Add a thick layer of whipped topping, chill it well… and finish with those colorful sprinkles 
Slice it cold and watch the inside… soft, creamy, and full of color.
