How To Make Your Own Chocolate Cake With Sprinkles On Top

Once you’ve gathered all the ingredients, you can follow these simple steps to create your very own chocolate cake with sprinkles on top and rainbow frosting layers:

Let’s get started…

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 and evenly divide the cake batter between the 3 pans.

Place 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

If you are using store-bought icing – divide the vanilla icing into 3 bowls and add the coloring described below.
Making Homemade icing: 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 cups 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 or a cake plate.

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
