Marshmallow Frosting Recipe

2 sticks of unsalted butter, softened
1 – 7oz jar marshmallow cream
2 teaspoons vanilla
3 cups powdered sugar
1 – 1 ½ Tablespoons heavy whipping cream

Instructions to make Marshmallow Frosting:

In a stand-up mixer mix together the marshmallow fluff, butter, and vanilla. Beat for about 2 minutes until fluffy.
Add half the powdered sugar and 1 tablespoon of heavy whipping cream. Turn the mixer on low so that powdered sugar doesn’t go everywhere!
Add the remaining powdered sugar and mix until it’s well combined. Add about ½ tablespoon of heavy whipping cream if necessary.

This recipe will frost a 9×13 cake. a 9-inch layer cake or 24 cupcakes if icing with a knife and not piping the icing. I would do the recipe 1.5 times if you want to pipe the recipe onto the cupcakes.

I would love to use this recipe to make Smores marshmallow cupcakes. My kids thought it tasted so good! Plus it is so easy to just throw into a mixer. It’s a great way to add a little variety to your cakes.

Here’s a sneek peek of the cake I am working on! I will update this post when I publish the recipe!
