Introduction
The kitchen smells like warm butter and roasted peanuts the moment I start this Homemade Peanut Butter Frosting Recipe — the mixer hums, and small clouds of powdered sugar puff up as I scrape the bowl. This always takes me back to Sunday dinners. If you want a rich pairing, I love spooning this on a warm dump cake; try my go-to peanut butter cup dump cake for a simple dessert to practice on.

Ingredients You’ll Need
- 1 cup unsalted butter, room temperature
- Unsalted butter helps control salt.
- 1 cup creamy peanut butter
- Use smooth for silky texture.
- 3–4 cups powdered sugar
- Start with 3 cups; add for stiffness.
- 1 tsp vanilla extract
- Adds warmth and rounds flavors.
- 1–2 tbsp milk or heavy cream (as needed)
- Heavy cream gives extra richness.
If you want a parfait or trifle to pair with this frosting, try layering it with pudding from my banana pudding recipe for extra nostalgia.
How to Make It
- First, let the butter sit until soft but not greasy; it should give slightly when pressed.
- Then, put butter and peanut butter in a mixing bowl and beat on medium for about 1 minute, until light and fluffy and you see small air bubbles.
- Next, reduce speed to low and add 3 cups powdered sugar and the vanilla; beat until incorporated and the mix looks smooth.
- If it feels loose, add another cup of powdered sugar a little at a time until it holds shape.
- If the frosting becomes too thick, add 1 tablespoon of milk or heavy cream, then beat again; aim for a pipeable, ribbon-like fall.
- Meanwhile, scrape the bowl down once or twice to keep everything even.
- Finally, spread or pipe onto cooled cakes, cupcakes, brownies, or cookies; the frosting should hold soft peaks when done.
- Serve at room temperature so it’s creamy and easy to bite.
Kitchen Tips (From My Kitchen)
- Time-saver: Use a paddle attachment and room-temp ingredients to blend faster.
- Common mistake + fix: If it tastes overly sweet, add a pinch of salt and a splash of milk, then re-taste.
- Simple variation: Stir in 1/4 tsp cinnamon or 2 tbsp melted chocolate for a flavored twist.
Serving Ideas
- Top a simple sheet cake for a cozy weeknight celebration; garnish with chopped peanuts.
- Pipe it on vanilla cupcakes for a birthday treat; add a drizzle of melted chocolate.
- Dollop on warm brownies and serve with vanilla ice cream for holiday guests.
- Spread on cookies for an easy afternoon snack; a sprinkle of flaky sea salt makes it special.
- Try it in a layered parfait with banana slices and whipped cream for brunch.
For a savory contrast on the table, serve slices of the finished dessert next to my baked pasta nights like the best Italian stuffed shells recipe.
Storing & Leftovers
- Fridge: Store in an airtight container for 5–7 days.
- Freezer: Freeze up to 2 months; thaw in fridge overnight.
- Reheat: Bring to room temperature and re-whip briefly to restore texture.
Leftover idea: Spread it between cookies to make peanut butter sandwich cookies.

FAQs

Q: Can I freeze the frosting?
A: Yes, freeze in a sealed container for up to 2 months; thaw in the fridge and whip briefly before using.
