What kind of peanut butter should I use for this 3 Ingredient Peanut Butter Frosting?

The traditional store-bought kind is the best choice for this recipe. Avoid any type of crunchy varieties at the grocery store, and keep it smooth with the regular creamy option.

Natural and organic alternatives can be difficult to incorporate because of oil separation or can result in your frosting being grainy.

It’s recommended that you use peanut butter instead of other nut butters for this reason as well since many substitutes can have a rougher texture.

You can choose to include vanilla and heavy cream for an extra layer of flavor and a fluffy texture. If you decide to mix these in, here’s how:

After step two above, add vanilla and mix well. For fluffier frosting, add heavy cream 1 tablespoon at a time, mixing for 2-3 minutes until light and fluffy.

Peanut Butter Frosting piping tips

  • If you don’t have a piping bag on hand, you can use a gallon-sized Ziploc bag (not a freezer bag) by cutting a small piece off the bottom corner and placing the tip inside
  • Twist the end of the pip bag to close it off, but still use one hand to hold it closed

How to store Peanut Butter Buttercream Frosting

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

Let it warm up to room temp before using it again, so it softens up a bit. This will make it a lot easier to spread.

A quick whip from your electric mixer will fluff it up again.

Peanut Butter Buttercream Frosting FAQs

What’s the difference between frosting and icing?

Both icing and frosting are delicious essentials to our beloved baked goods, but there are notable differences between them. A peanut butter icing recipe would give you more of an overall coating than a fluffy spread.
Frosting is generally thicker and fluffier than icing, while icing is thinner and glossy. The butter in this recipe makes it a frosting, as opposed to peanut butter icing.
This means frosting holds its shape better and is great for crowning your cupcakes with lovely piping. Icing tends to be a bit sweeter and acts more like a glaze, adding smoothness and shine. 

Why do I have air bubbles in my frosting?

Vigorous whipping can fold in unwanted pockets of air into the frosting, creating bubbles.
To prevent this, use a slower speed on your mixer or whip the ingredients by hand. You can even try these methods to remove some air bubbles if they’ve already started to form.
Softening the butter to room temperature helps your frosting to whip up more smoothly, so don’t neglect this step!

Why is my peanut butter frosting oily?

Peanut butter frosting can become oily if you use natural peanut butter. If the oil separates in the jar, it will separate on the frosting as it sits. Use a peanut butter like Jif or Skippy that doesn’t need to be mixed prior to using.

Why is my peanut butter frosting grainy?

Your peanut butter buttercream can become grainy if you didn’t mix it enough, or the butter isn’t softened through. Make sure to soften it before you get started and mix thoroughly to get rid of any sugar grains.
If you’re still unhappy with the consistency, try sifting the powdered sugar before adding it to the butter and peanut butter. This helps prevent clumps too!

  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
