Peanut Butter Frosting Recipe

If you love peanut butter as much as I do, then you’re going to be obsessed with this frosting. I still remember the first time I made it—honestly, I was just craving something sweet, creamy, and rich but not the same old chocolate frosting.

I whipped this up, spread it on a cake, and boom—it became my all-time favorite. And trust me, once you try it, you’ll feel the same.

Let’s get straight into it.


Why Peanut Butter Frosting is So Good

This frosting is smooth, creamy, and full of peanut butter flavor. It’s not too sweet, but just the right balance of salty and sweet.

It tastes amazing on chocolate cake, vanilla cupcakes, brownies, or even just spread on cookies. The best part? It’s super simple and quick to make.


Ingredients You’ll Need

You don’t need anything fancy—just basic stuff you probably already have at home.

  • Peanut Butter (creamy, not chunky) – This is the star. Creamy peanut butter gives the best smooth texture.
  • Butter (softened) – Adds richness and helps the frosting whip up light and fluffy.
  • Powdered Sugar – Sweetens and thickens the frosting.
  • Vanilla Extract – Just a little makes the flavor pop.
  • Milk (or heavy cream) – To adjust the consistency so it’s spreadable.

Step-by-Step: How to Make Peanut Butter Frosting

  1. Beat the butter and peanut butter together.
    Use a hand mixer or stand mixer. Whip until creamy and smooth.
  2. Add powdered sugar slowly.
    Mix in one cup at a time so it blends well and doesn’t clump.
  3. Mix in vanilla.
    Just a splash to give it that warm flavor.
  4. Adjust with milk.
    Add one tablespoon at a time until the frosting is soft, fluffy, and spreadable.

That’s it! In just 10 minutes, you’ve got frosting that tastes like heaven.


Tips to Make It Even Better

  • If you want a stronger peanut butter flavor, add an extra spoonful of peanut butter.
  • For chocolate lovers, mix in a couple of tablespoons of cocoa powder.
  • Want it extra light? Use heavy cream instead of milk.
  • Always sift powdered sugar first to avoid lumps.

What to Use Peanut Butter Frosting On

  • Chocolate cake (my favorite combo!)
  • Vanilla cupcakes
  • Brownies
  • Sandwich cookies
  • Even as a dip for fruit like apples or bananas

Honestly, I’ve even eaten a spoonful straight from the bowl. No shame.


How to Store Peanut Butter Frosting

If you have leftovers (rare, but it happens), here’s what to do:

  • Room Temperature: Good for up to 2 days if it’s not too hot.
  • Fridge: Store in an airtight container for up to a week. Let it soften before using again.
  • Freezer: Freeze for up to 2 months. Thaw in the fridge overnight and rewhip before spreading.
