BEST Frosting Ever!

When I say that this is the best Peanut Butter Icing, I’m serious! It’s smooth enough to go on any dessert, like cupcakes or cake. You could also eat this frosting by the spoonful, that’s how good it is.

Many people actually ask me what I think this whipped easy peanut butter frosting recipe tastes best with while it tastes good with just about anything, peanut butter and chocolate is the perfect pairing. I paired them with chocolate cupcakes, but chocolate cake, brownies or even a brownie pie would suit this frosting.

Homemade peanut butter frosting is the perfect 6 ingredient frosting recipe for any dessert you make. If you’re a peanut butter lover you’re going to love this recipe!

Ingredients Needed

  • Peanut Butter – creamy works best so that you keep a smooth texture. Be sure to use no-stir kind of peanut butter (like Skippy or Jif).
  • Powdered Sugar: Also called confectioners’ sugar
  • Unsalted butter – softened at room temperature. You can swap salted butter but be sure to reduce the added salt.
  • Heavy whipping cream – I always add heavy cream to my frosting recipes because it makes them more fluffy and whipped.

How to make Peanut Butter Buttercream Frosting 

  • Beat peanut butter and butter in a large bowl with a hand mixer until creamy (or in the bowl of a stand mixer fitted with the paddle attachment).
  • Mix in 1 cup of powdered sugar at a time, slowly, until the mixture is crumbly. Add salt and vanilla extract and mix again.
  • Add in heavy whipping cream and beat frosting until smooth, adding more heavy whipping cream until you reach the desired consistency (I always add 6 tablespoons). You can use milk if you want but it won’t be as fluffy.
  • Pipe or frost as desired.

How Much Frosting This Makes

This recipe makes enough frosting for:

  • 24 cupcakes (12 if piled super high)
  • One 9×13-inch sheet cake
  • 8-inch layer cake (with 2 layers)
  • Approximately 36 cookies (great on chocolate sugar cookies)
  • Double the recipe to make a 9-inch layer cake or if you want to pile frosting high on cupcakes.

Expert Tips

  • You can freeze peanut butter frosting for up to 3 months. 
  • I prefer using a stand mixer to make frosting because it will incorporate the powdered sugar into the butter and peanut butter mixture better, allowing you to use less heavy cream. Stand mixers also whip the cream better, making the frosting even fluffier.

FAQs

Why is my peanut butter frosting grainy? 

If you didn’t mix the frosting all the way, you might notice a grainy texture. Add some extra whipping cream if needed and mix until it’s not grainy any longer. 

Why did my peanut butter frosting separate? 

The biggest reason that the frosting separates is that people use natural peanut butter. Make sure to use a no-stir peanut butter. 

How to store peanut butter frosting?

Store frosting in an airtight container and keep it in the fridge. For best results, use it within 2 days.

  1. This frosting is so so good. I let the leftover set up in the fridge, scooped out small balls then dipped in setting chocolate for peanut butter truffles. They were heavenly.
