Step 1

Preheat oven to 350 degrees. Place cupcake liners in cupcake tin.

Step 2

Add cake mix, eggs, and rainbow sherbet into mixing bowl. Stir to combine. Add in the flour and give a few stirs until just mixed in.

Step 3

Add cake batter to the cupcake liners using a 1/3 cup of batter, filling until the cupcake liners are about 2/3 full.

Step 4

Bake for 15 minutes or until baked through, check with a toothpick. Let the cupcakes cool in the baking tin for 5 minutes then remove to wire rack to continue cooling.

Step 5

Add all ingredients to large mixing bowl.

Step 6

Mix on low speed for 2-3 minutes until ingredients are combined. Then mix on medium speed for an additional 3 minutes until frosting is peaking, meaning that it is holding it's shape.

Step 7

Separate into three bowls and add a flavor packet to each bowl. Stir to completely combine the flavor into the frosting, should have a uniform color throughout.

Step 8

Frost using all three frostings, tutorial at House of Yumm here. I used a Wilton 2D tip for these cupcakes.
