Kool-Aid Frosting

My kids wanted to bake cupcakes the other day and we were low on ingredients. All we had was a box of cupcake mix and some other basic cupcake ingredients. What were we missing? The FROSTING! That’s when we decided to get creative. We opened up the pantry and got to work…

Supplies

Cupcake liners
Cupcake tin
Hand mixer
Butter knife
Teaspoon for measuring (or smaller!)

What you will love about this recipe is that it is so simple to make. We didn’t use any fancy tools, frosting pipes, or anything to make these rainbow treats. I frosted this one and my kids did the rest. Theirs turned out perfectly too which makes this a cupcake recipe for ANY skill level! Bring on the kids – this one is for them.

Ingredients

Box of cupcake mix (any flavor). Usually requires water, oil, and eggs
Packets of powder Kool-Aid (any flavor)
Crisco stick (it’s a stick of shortening used for any baking recipe)
Whole milk
Powdered sugar

Recipe

Bake the cupcakes according to the directions on the box and let them cool completely. Make the Kool-Aid Frosting while they bake!

With an electric mixer, mix the Crisco and milk on medium speed. Slowly add in the powdered sugar. Once all of the powdered sugar is added, mix on high for 1-2 minutes. If needed: add additional milk or powdered sugar to achieve the consistency you’re looking for.

Divide the frosting into different bowls, depending on how many Kool-Aid flavors you are using. We used 4. Put 1/2 teaspoon of powder into each bowl.

Use more or less to achieve the color and flavor intensity you want! You can’t go wrong. This recipe will frost about 8 cupcakes. Make more frosting as needed.

Next, use various spoons of a butter knife to add small amounts of the different colors to the tops of the cupcakes like this:

Gently smooth the frosting out and watch the rainbow appear! Add sprinkles on top for even more fun (my kids couldn’t resist!).

Did you know that the Crisco frosting base can be used with ANY flavoring? You can also add a tablespoon of vanilla to the base recipe if you want to make the plain vanilla frosting. It’s delicious and so easy.
