Easy Peanut Butter Frosting Recipe

We were celebrating my daughter’s birthday a few years ago and she requested peanut butter frosting. I looked at her sweet face while asking and just couldn’t say no.

So, I went searching in our pantry and pulled out a jar of Jif peanut butter and created this very recipe. It’s only 3 ingredients, but comes out creamy, light, and fluffy every single time.

Since then, any party we go to (even the stuffed animals’ birthday parties) has to have this icing. Everyone raves about the frosting though, so of course, I have to make it. Thank goodness it’s easy for me put together and tastes incredible.

I do like to add some heavy cream when I have it on hand to up the creamy factor even more, but it’s not needed to make this peanut butter frosting.

3 Ingredient Peanut Butter Frosting tips

  • Use a store bought brand like Jif or Skippy. Using an organic peanut butter can cause oil separation in the frosting.
  • Add in some heavy cream and vanilla for more flavor and an extra fluffy texture.
  • Soften the butter on the counter or in the microwave for the smoothest icing.
  • Sift the powdered sugar to avoid any clumps or lumps.
  • Use a Wilton 1M tip for the cupcakes shown!
  • Use a gallon-sized Ziploc bag if you don’t have a piping bag. Just cut a small piece off the bottom corner, place the tip inside, then fill it with frosting.

How to use Peanut Butter Buttercream Frosting

I use this frosting recipe to top 18-24 cupcakes, a 13 by 9-inch sheet cake, or a full 2 layer 8-inch round cake or one of these fun ideas.

How to store Peanut Butter Icing

You can store this frosting in an airtight container on the countertop for two days, or in the fridge for about a week.

If using it straight from a bowl, let it warm to room temperature, whip it up with by hand or with a stand mixer for a quick minute, then spread or pipe as needed.

Peanut Butter Frosting Recipe FAQs

Why Do I Have Air Bubbles in My Frosting?

Air bubbles can form if you’re mixing the frosting too fast. Use a slower speed on your stand or hand mixer to avoid any bubbles. Also, use room temperature butter for the smoothest icing.

Why Is My Homemade Peanut Butter Frosting Oily?

This can happen if you use organic or natural peanut butter as it’s more oily by nature and will separate when it sits. Use a smooth peanut butter like Jif or Skippy for a creamy texture.

Why Is My Peanut Butter Icing Grainy?

The butter needs to be fully softened, but not melted to get that creamy texture, otherwise it will turn grainy. Sifting the powdered sugar will also help prevent any graininess or lumps in the frosting.

  1. I made the frosting, but it is very thin… Kind of wondering why? Are used at the 3/4 cup of Jiff, one cup of Miyokos , vegan butter, and 3 cups of powdered sugar.

    • Hi KayCee, it could either be the vegan butter that was used or the powdered sugar wasn’t sifted before measuring — this could cause far less powdered sugar to be used than what shows in the measuring cup.

      In this case, I would add more powdered sugar until it thickens up.

    • Hi Suzie, this makes enough for 18 cupcakes, so it will be very close on a two layer cake. It will work if you like your frosting thinner, but if you like with a thicker coat, I would recommend doubling the recipe.

  2. 5 stars
    I made this in less than 5 minutes. Only difference is I used vanilla flavored coffee creamer for the smoothness of the frosting. People that had problems didn’t soft their sugar, let butter get to room temperature or didn’t beat till smooth light consistency. This is THE BEST
