Peanut Butter Frosting
Using one bowl and just five ingredients, you can whip up a batch of this deliciously easy peanut butter buttercream frosting in just 10 minutes!
- 1 cup butter softened
- 1 cup creamy peanut butter room temperature
- 3 cups powdered sugar up to 4 cups for a stiffer frosting
- 1 tsp vanilla extract optional
- ¼-½ tsp salt
- 1-2 tbsp milk or cream up to ¼ cup if desired
Add the softened butter and peanut butter to the bowl of a standing mixer or large bowl with a hand held mixer.
Mix on medium to medium high for 2-3 minutes, until the butter and peanut butter is combined. Mixing the butter/peanut butter so long make it really light and fluffy.
Add the powdered sugar, ¼ tsp salt, and vanilla and mix on low for a minute until it incorporates. Mixing on low makes sure the powdered sugar doesn’t spill out and get everywhere.
Once it’s incorporated, mix on medium high for another 3-4 minutes until it is fluffy again.
At this point, gauge the consistency and flavor. If you want it thinner you can add a tablespoon or two of milk or cream. You can also add a bit more salt if you think it needs it. Remix for another minute until combined.
- This recipe makes about 3-3.5 cups of frosting.
- For a smooth frosting, use regular smooth peanut butter instead of the natural kind you stir, or crunchy peanut butter.
- Make sure your butter and peanut butter are both at room temperature so the combine easily.
- If your powdered sugar is very stiff or hard, put it through a sifter so there are no lumps in your buttercream.
- Test to gauge the consistency and flavor. If the frosting is too thick you can add a tablespoon or two of heavy cream or milk. If it’s too thin, you can add a few more tablespoons of powdered sugar. You can also add more salt if you think the frosting needs it.
- If you’re looking for a stiffer frosting, you can add up to another cup of powdered sugar.
- This frosting will last up to a week in the fridge or up to 3 months in the freezer, making sure to store tightly in an airtight container.
