Prepare each color of cake mix as directed on the package.
Line a cupcake pan with the white cupcake liners.
Fill each cupcake liner ¾ full.
Bake as directed on the package.
Allow to cool completely. While the cupcakes are cooling prepare the buttercream frosting.
Make the Buttercream Frosting
Beat the butter in a large bowl with a hand mixer or in the bowl of a stand mixer until lump-free, about 3 minutes.
Slowly add the powdered sugar one cup at a time, beating in between each cup.
After the first cup of powdered sugar add the almond extract to the bowl then continue adding powdered sugar.
After the fifth cup of powdered sugar check the consistency of the buttercream frosting. If it has thickened to the consistency of peanut butter then you can skip the last cup of powdered sugar.
Once all the powdered sugar has been mixed into the butter add the heavy whipping cream to the bowl.
Beat on high for 3-5 minutes or until the frosting is thick and fluffy.
How to Decorate the Cupcakes
Using a butter knife or a small spatula spread about 2 tablespoons of frosting onto each cooled cupcake.
As each cupcake is frosted add a row of five corresponding colored Skittles® candies down the center of each cupcake. Use red Skittles for the red cupcakes and so on.
On the dessert table arrange 36 cupcakes into the shape of a large football.
Arrange the remaining cupcakes around the football cupcakes on the table.
