The Best Peanut Butter Buttercream Frosting Recipe
I’m in love with my peanut butter buttercream frosting recipe. I think it is so light and silky smooth, which makes the perfect addition to a cake! If you love peanut butter too, I think you’ll really love this buttercream recipe!
To make the peanut butter buttercream frosting, you’ll need:
- 5 cups (625 g) powdered sugar, measured then sifted
- 1 ½ cups (339 g) unsalted butter slightly chilled
- 1 cup (250 g) peanut butter smooth
- ¼ cup (57.75 g) heavy whipping cream
- 1 Tbsp (13 g) vanilla extract
- Pinch of salt
First, beat the butter and the peanut butter for about 3 to 5 minutes in a stand mixer with a paddle attachment. You want it to lighten in color and be smooth in texture.
Next, gradually add the sifted powdered sugar, followed by the vanilla, salt, and cream while your mixer is on low speed. Stir all of the ingredients to combine.
Lastly, beat your mixture for an additional 5 minutes with your mixer on medium-high speed. Scrape the sides and bottom of the bowl a couple of times during the process to make sure it all gets mixed together well. The buttercream will become lighter in color and should take on a fluffy texture.
