This peanut butter frosting recipe is perfect for peanut butter lovers and used for topping your favorite chocolate cake, cupcakes, fudge brownies or cookies.
The Best Homemade Peanut Butter Frosting Recipe
If you are a peanut butter lover, you will really like this frosting. You can whip it up in just a few minutes and use it to top of your favorite dessert. Of course, the best pairing in my opinion is on top of all things chocolate, but it goes great with all sorts of dessert flavors.
Homemade frosting is awesome because it’s usually very easy to make and can be used to make a boring boxed cake mix come to life. Our Homemade Cream Cheese Frosting Recipe is another one that I just love so much. Frosting is so simple to make at home and tastes so much better than store-bought frostings.
Ingredients You’ll Need
Most, if not all, of these ingredients are things you’ve probably got in your pantry right now. Just five simple things is all you need. Full amounts are in the recipe box below.
- Creamy Peanut Butter – Feel free to use whatever brand or kind of peanut butter you love the best, including natural peanut butter.
- Unsalted Butter – It’s important you don’t grab salted butter because we are adding salt in ourselves.
- Vanilla – This gives a lot of the flavor so always try to use real vanilla and not imitation.
- Salt – Just half a teaspoon.
- Milk – 2% or whole milk.
- Powdered Sugar – I always like to swift the powdered sugar to make sure there aren’t any clumps, but this is totally optional.
How To Make Peanut Butter Frosting
- Using a stand or hand mixer, beat the butter and peanut butter together. (Make sure your butter is soft first.)
- Add in just half the powdered sugar, the vanilla, salt and milk and mix again.
- Include the rest of the powdered sugar until the frosting is creamy. Be sure to scrape the sides of the bowl to incorporate all the ingredients.
This will make enough frosting for about 12-24 cupcakes (depending on their size and how much frosting you use per cupcake) or two round 9-inch cakes including in between layers. Super easy, right?
