Ingredients:
Yield: 4 cups
1 C butter, softened
1 1/2 C creamy peanut butter
1/4 C milk, or as needed (if you need more, add a tsp at a time)
4 C powdered sugar
2 tsp vanilla
Directions:
Place butter and peanut butter into a medium bowl. Beat with an electric mixer.
Gradually mix in sugar. When it starts to thicken, incorporate milk, one Tbsp at a time until all the sugar is mixed in, and the frosting is thick and spreadable.
Beat for at least 3 minutes for it to get good and fluffy.
