What Kind of Peanut Butter Should I Use?

For the best results, use creamy peanut butter—not the natural kind that separates in the jar. Commercial brands like Jif or Skippy work best as they offer consistency and a perfectly smooth texture. Natural peanut butters tend to alter the structure and can leave your icing too oily or too gritty.

Ingredients for the Peanut Butter Icing

Creamy Peanut Butter – The star of the show. Provides rich flavor and smooth texture.

Unsalted Butter – Adds creaminess and structure. Room temperature is key for easy blending.

Powdered Sugar – Sweetens and thickens the icing without any grittiness.

Heavy Cream (or Milk) – Adjusts the consistency to make it spreadable or pipeable. Heavy cream gives it extra richness.

Vanilla Extract – Just a splash enhances the overall flavor profile, balancing the nutty richness.

How To Make the Peanut Butter Icing

Step 1: Cream the Butter and Peanut Butter

In a large mixing bowl, beat the unsalted butter and creamy peanut butter together using a hand mixer or stand mixer on medium speed until the mixture is completely smooth and fluffy—about 2–3 minutes.

Step 2: Add the Vanilla Extract

Pour in the vanilla extract and continue mixing for another 30 seconds. This adds warmth and depth to the icing’s flavor.

Step 3: Gradually Incorporate the Powdered Sugar

Reduce the mixer speed to low and begin adding the powdered sugar, about 1/2 cup at a time. Mix well between each addition to prevent clumping. Once all the sugar is in, increase the speed and beat until light and fluffy.

Step 4: Adjust the Consistency

Add heavy cream (or milk) one tablespoon at a time until you reach your desired consistency. For piping, you’ll want a thicker texture; for spreading, a softer texture works best.

Step 5: Whip to Finish

Whip the entire mixture on high speed for another minute or two until everything is fully combined and irresistibly creamy. Your peanut butter icing is now ready to use!

How to Serve and Store This Peanut Butter Icing

This icing pairs beautifully with chocolate, banana, or vanilla cakes, cupcakes, cookies, and even brownies. For a quick treat, spread it over graham crackers or apple slices. It’s also thick enough to be piped into decorative shapes if you’re decorating cupcakes or cakes.

Store leftover icing in an airtight container in the refrigerator for up to one week. Before using again, let it come to room temperature and re-whip it for the best texture. You can also freeze it for up to 2 months—just thaw overnight in the fridge before use.

Frequently Asked Questions

How long can I keep peanut butter icing at room temperature?

If you’re using it the same day, it’s fine at room temperature for up to 6 hours. After that, refrigeration is recommended.

Can I use crunchy peanut butter instead of creamy?

It’s not ideal. Crunchy peanut butter changes the texture, making the icing harder to spread or pipe smoothly.

Can I make this icing dairy-free?

Yes! Use a plant-based butter and swap the cream with almond or oat milk. Just know the flavor and consistency may differ slightly.

How do I make this frosting less sweet?

Try reducing the powdered sugar slightly and increasing the peanut butter and cream. Just be aware the structure may be softer.

Is this icing suitable for piping decorations?

Absolutely! It holds its shape very well if you use the right consistency—don’t over-thin with too much cream.
