Prepare the cake mixes according to the box directions.
Split batter evenly into 4 bowls.
In the first bowl (to create the purple layer) add 6 red drops and 5 blue drops.
In the second bowl (to create the yellow layer) add 5 yellow drops.
In the third bowl (to create the pink layer) add 6 drops of red food coloring and 1 drop of blue.
In the fourth bowl (to create the blue layer) add 4 blue drops and 2 green drops.
Bake each layer in an
8” round cake pan for 23-25 minutes.
Allow cakes to cool. Set aside.
In a medium bowl, mix whipped cream cheese, sweetened condensed milk and Cool Whip until well combined.
Crumble each cake, setting aside a ¼ cup of each color for topping.
To assemble trifle, alternate each color of cake with a layer of cream. It's up to you how you would like to layer the colors, but I chose, purple, yellow, pink and blue at the top.
To finish, sprinkle remaining cake crumbs on top.
