Ingredients

Ingredients:

1 cup creamy peanut butter (9 ounces) (don't use "natural" or "organic")
10 tablespoons unsalted butter softened room temp
2-2 ½ cups powdered sugar sifted (8-10 ounces)
2-4 tablespoons heavy cream or milk
½ teaspoon vanilla extract
pinch of salt optional

Instructions

In a large bowl, use a hand mixer to beat the butter until smooth. Then add the peanut butter and beat until very smooth.
Gradually add in the powdered sugar, mixing well after each addition. It will get quite stiff as you get closer to adding 2 cups. Taste-test and determine if you want to add the last ½ cup of powdered sugar. Beat in the vanilla extract and a pinch of salt (salt is optional).
Now, thin the frosting down by adding 1 tablespoon of cream or milk and beating until smooth. Continue to add small amounts of cream or milk until the frosting is the desired consistency.
If the frosting becomes too thin, then add a bit more powdered sugar.
Beat the mixture on high speed for an additional minute or two until light and fluffy.

Notes

Milk or Cream? You can use either heavy cream or milk to thin down the frosting, but if you use milk be careful because it will thin down the frosting much faster.

Frosting yield: 2 ¾ cups. (about 1 lb 8 ounces).

How to Store: Store the frosting in the fridge up to 5 days. Allow it to come to room temperature and then re-whip in order to frost your cake/cupcakes/whatever it may be!
