How to make peanut butter frosting
Place room temperature unsalted butter and creamy peanut butter in a mixing bowl. Use an electric mixer on medium and beat the butter for 1 minute, until whipped and fluffy.
Add in the powdered sugar and vanilla extract, beat again on low for 1-2 minutes, scraping down the sides of the bowl, until everything is incorporated.
If the frosting is too thick, add a tablespoon of milk or heavy cream, and beat until creamy.

Whip it! Want fluffy frosting? Whipping is the key!

How to store Homemade Peanut Butter Frosting
You can store frosting in a sealed container on the counter for up to 2 days.
However, you can store frosting in a sealed container in the fridge for up to 1 week. Before using, place the frosting on the counter and allow it to come to room temperature. Give it a quick whip with an electric mixer before using.
