• Preheat oven to 350 degrees and spray the cake pans with pam baking spray
• Using a large bowl, beat the cake mix, butter, eggs, and milk until combined and smooth
• Evenly divide the cake batter between the 3 pans
• Place them into the oven and bake for 22-26 minutes or until a toothpick comes out clean
• Allow cooling completely before covering with foil and setting them aside to use the next day. By doing this, it will allow you to get a clean cut slice of cake

Frosting Directions

• Using a standing mixer, beat the butter, powdered sugar, vanilla, and heavy whipping cream together until combined, smooth and stiff with peaks
• Once the frosting is made, divide the 1 ½ C of frosting into 2 small bowls, leaving the rest in the mixing bowl for the outer layer of the cake
• In one bowl, mix in 4 drops of purple gel food coloring
• In the second bowl, mix in 4 drops of blue gel food coloring

Building the cake

• Remove the cakes from the pans and onto the cake boards
• Using a cake slicer, slice off the tops of the cakes to create a flat cake layer
• Using one of the cake layers as the bottom layer, scoop the purple frosting onto the cake layer and spread it evenly
• Place a second cake layer on top
• Scoop the blue frosting on top of the cake layer and spread evenly
• Place the third cake layer on top of the frosting
• Smooth the two frostings on the outside to create a smooth layer on the outside
• Using the white frosting, completely coat the cake in the white frosting and smooth evenly
• Place the cake onto a cookie sheet
• Using the sprinkles, completely coat the cake in the sprinkles
• Once coated, place them in the fridge for a few hours to allow them to harden
