🥜 Homemade Peanut Butter Frosting 🍯

The Sweet Nutty Hug for Your Cakes & Cupcakes


💌 Introduction

Peanut butter lovers, this one’s for you! This Homemade Peanut Butter Frosting is a rich, creamy, and fluffy dream that turns any dessert into an unforgettable treat. Whether you’re spreading it on chocolate cake, piping it onto banana cupcakes, or licking it straight from the spoon (we won’t judge), this frosting delivers a perfect blend of salty and sweet. A true kitchen classic, it’s made from simple ingredients with big flavor—ideal for both casual bakers and dessert connoisseurs alike.


🛒 Ingredients

(Enough to frost a 9-inch double-layer cake or 24 cupcakes)

  • 2 sticks (1 cup) unsalted butter, room temperature
  • ¾ cup creamy peanut butter (do not use natural peanut butter; use a stabilized kind like Jif or Skippy)
  • 3–4 cups powdered sugar (sifted for smoothness)
  • 1–2 tablespoons heavy cream or milk (to reach desired consistency)
  • 2 teaspoons pure vanilla extract
  • ¼ teaspoon salt (optional, to taste)

🧁 Instructions

Step 1: Cream the Butter & Peanut Butter

In a large bowl using a hand mixer or stand mixer fitted with the paddle attachment, beat the butter and peanut butter together on medium-high speed until light, creamy, and smooth—about 2–3 minutes.

Step 2: Add the Vanilla & Salt

Beat in the vanilla extract and a pinch of salt (if using) until fully combined. The salt enhances the flavor and cuts through the sweetness.

Step 3: Add Powdered Sugar

Gradually add in the powdered sugar, 1 cup at a time, beating well after each addition. Scrape down the sides as needed. It will look thick and crumbly at first—don’t panic!

Step 4: Adjust Consistency

Add heavy cream or milk, 1 tablespoon at a time, until your frosting is light, fluffy, and easily spreadable. Beat for another 2–3 minutes to whip in air and give it that dreamy texture.


🧪 Method Notes

  • Butter & peanut butter must be at room temp—this helps everything blend smoothly.
  • Sifting the powdered sugar removes lumps for a silky-smooth finish.
  • Whipping at the end gives it volume, which is great for piping and spreading.
  • Chill if needed: If your frosting is too soft to pipe, refrigerate it for 15–20 minutes.

📜 Brief History

Peanut butter as a dessert ingredient dates back to the early 1900s, after its invention in the U.S. Around the 1920s and 30s, as sugar became more affordable and home baking surged, peanut butter started showing up in cookies, pies, and yes—frostings! This frosting pays homage to decades of comfort food culture, where simplicity and taste reigned supreme.


🏗️ Formation

This frosting forms through the emulsification of fat (butter and peanut butter) with sugar and moisture (milk/cream). Beating it traps air, making it fluffy and light. It’s a classic American buttercream style, but with a nutty twist.


💞 Conclusion

This frosting isn’t just a topping—it’s a hug in dessert form. Perfect on chocolate cake, banana bread, vanilla cupcakes, brownies, or even as a dip for apple slices or pretzels. Make it once, and it’ll become a forever favorite.
