INGREDIENTS

• 1 cup (225 g) Unsalted butter, softened to room temperature
• 1 ½ cups (375 g) Creamy peanut butter (standard commercial brands work best)
• 4 cups (500 g) Powdered sugar, sifted
• 2–3 tablespoons (30–45 ml) Heavy cream or whole milk
• 1 teaspoon (5 ml) Pure vanilla extract
• ¼ teaspoon (1.5 g) Salt (optional, omit if your peanut butter is very salty)

INSTRUCTIONS

1. Cream the butter and peanut butter: Place the softened butter and creamy peanut butter in a large mixing bowl. Beat them together on medium-high speed for about 2–3 minutes using a stand mixer or handheld electric mixer until the mixture looks pale and completely smooth.
2. Add the vanilla and salt: Mix in the vanilla extract and salt. Continue beating for another 30 seconds to ensure the flavors distribute evenly throughout the base.
3. Incorporate the sugar: Turn your mixer to the lowest setting and gradually add the sifted powdered sugar one cup (125 g) at a time. Mixing on low prevents a “sugar cloud” from filling your kitchen!
4. Add the liquid: Pour in 2 tablespoons (30 ml) of heavy cream. Increase the mixer speed to medium and beat for another minute.
5. Whip to perfection: Turn the mixer up to high and whip the peanut butter frosting for a full 2 minutes. If the consistency feels too thick, add the remaining tablespoon of cream. If it feels too soft, add another 1/4 cup (30 g) of powdered sugar.
6. Smooth out air bubbles: Before frosting your treats, use a rubber spatula to hand-stir the frosting for a minute. This knocks out any large air pockets, making it extra smooth for piping.

TIPS & VARIATIONS

Pro Cooking Tips

• Room Temperature is Key: Make sure your butter is soft but not greasy. If it’s too cold, your peanut butter frosting will be lumpy; if it’s melted, the frosting won’t hold its shape.
• Sift Your Sugar: Always sift your powdered sugar before adding it to the bowl. This is the secret to achieving that professional, ultra-smooth texture without any tiny sugar clumps.
• The “Natural” PB Rule: I recommend using a standard creamy peanut butter (like Jif or Skippy). Natural peanut butters that require stirring are often too oily and can cause the frosting to separate.

Fun Ingredient Swaps

• Chocolate Peanut Butter: Sift in ½ cup (45 g) of unsweetened cocoa powder along with the powdered sugar for a rich chocolate version.
• Vegan Option: Swap the butter for a vegan butter stick and use almond milk or coconut cream instead of heavy cream.
• Maple Twist: Replace the vanilla extract with maple extract for a warm, autumnal flavor profile.

Storage & Make-Ahead Tips

• Fridge: You can store this frosting in an airtight container in the refrigerator for up to 1 week. Before using, let it come to room temperature and give it a quick whip with your mixer to restore the fluffiness.
• Freezer: This peanut butter frosting freezes beautifully! Keep it in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before re-whipping.

SERVING IDEAS

This creamy peanut butter frosting is so versatile, you’ll find yourself looking for excuses to whip up a batch! Here are a few of my favorite ways to use it:

• The Classic Pairing: Slather a thick layer over moist chocolate cupcakes or a dark chocolate sheet cake. The saltiness of the peanut butter makes the chocolate flavor pop!
• Cookie Sandwiches: Pipe a dollop between two chewy oatmeal or chocolate chip cookies to create a decadent homemade treat.
• The Brownie Topper: Spread it over cooled brownies and drizzle with melted chocolate for a “Buckeye” inspired dessert bar.
• Fruit Dip: Use it as a sweet dip for crisp apple slices or pretzels—it’s a hit at parties and a favorite for the kids!
• Occasion Ready: This frosting is stable enough for elegant piping, making it perfect for birthday parties, backyard BBQs, or holiday dessert tables.

FAQs

Can I use crunchy peanut butter for this frosting? While you technically can, I highly recommend using creamy peanut butter. This peanut butter frosting is designed to be silky and smooth, making it easy to pipe through decorating tips. Crunchy peanut butter can clog your piping tips and may result in a grainier texture that is harder to spread.

How do I make the frosting stiffer for piping tall swirls? If you need a stiffer consistency for elaborate decorating, simply add more powdered sugar, ¼ cup (30 g) at a time, until it reaches your desired thickness. You can also chill the peanut butter frosting in the fridge for about 20 minutes before piping to help it hold its shape in warmer kitchens.

Why is my frosting grainy? Grainy frosting usually happens if the powdered sugar wasn’t sifted or if the butter wasn’t fully creamed. To fix this, continue beating the frosting on high speed for another minute or two. The friction and aeration often help dissolve those tiny sugar crystals for a smoother finish.

How long can cupcakes with this frosting sit out? Since this recipe contains a small amount of heavy cream, I recommend leaving frosted treats at room temperature for no more than 2 days (in a cool area). If your kitchen is warm, it’s best to store them in the refrigerator to keep the peanut butter frosting perfectly set.

Can I make this recipe without a stand mixer? Absolutely! You can use a handheld electric mixer and a large bowl. It might take an extra minute or two of whipping to get that signature “fluffy” look, but the results will be just as delicious.
