  • 2 sticks (1 cup) unsalted butter, at room temperature
  • ¾ cup creamy peanut butter
  • 2-3 cups powdered sugar
  • 1 teaspoon vanilla extract

  2. Next, add the powdered sugar and vanilla extract to the bowl. Beat the mixture on low speed for 1-2 minutes, ensuring to scrape down the sides of the bowl as needed, until all the ingredients are thoroughly combined.
  3. If the frosting appears too thick, you can adjust the consistency by adding a tablespoon of milk or heavy cream. Continue beating until the frosting becomes smooth and creamy.
  4. Now, it’s time to indulge! Spread or pipe the peanut butter frosting onto your favorite cakes, cupcakes, or brownies as desired. Whether you’re celebrating a special occasion or simply craving a decadent treat, this homemade frosting is sure to satisfy your sweet tooth.

Serving and Storage Tips:

  1. Serving Suggestions: When serving desserts topped with Homemade Peanut Butter Frosting, consider garnishing with chopped peanuts or a drizzle of melted chocolate for an extra indulgent touch. Pair your treats with a glass of cold milk or a cup of hot coffee for the perfect combination of flavors.
  2. Storage Instructions: If you have any leftover frosting, store it in an airtight container in the refrigerator. Homemade Peanut Butter Frosting can be kept for up to one week, allowing you to enjoy its creamy goodness whenever a sweet craving strikes.
  3. Bring to Room Temperature: Before using refrigerated frosting, allow it to come to room temperature. This will make it easier to spread or pipe onto your desserts, ensuring a smooth and flawless finish.
  4. Freezing Option: If you don’t plan to use all of the frosting within a week, you can freeze it for future use. Transfer the frosting to a freezer-safe container, ensuring it’s tightly sealed to prevent freezer burn. When ready to use, thaw the frosting in the refrigerator overnight and then bring it to room temperature before decorating your desserts.
  5. Re-whipping: After storing the frosting, you may find that it has become slightly firm. Simply re-whip the frosting with a mixer until it reaches the desired consistency. If needed, you can add a splash of milk or heavy cream to achieve the perfect texture.


  1. Chocolate Peanut Butter Frosting: For a decadent twist, add cocoa powder to the frosting mixture along with the powdered sugar and vanilla extract. The combination of chocolate and peanut butter creates a rich and indulgent frosting that pairs perfectly with chocolate cakes or brownies.
  2. Maple Peanut Butter Frosting: Substitute some of the powdered sugar with pure maple syrup to infuse the frosting with a delightful hint of maple flavor. This variation adds a unique sweetness to your desserts, making it ideal for autumn-inspired treats like pumpkin cupcakes or maple pecan bars.
  3. Honey Roasted Peanut Butter Frosting: Incorporate honey-roasted peanut butter instead of regular creamy peanut butter for a touch of sweetness and nuttiness. The caramelized flavor of the honey-roasted peanuts adds depth to the frosting, making it a delicious complement to banana bread or oatmeal cookies.
  4. Spiced Peanut Butter Frosting: Enhance the flavor profile of the frosting by adding a pinch of ground cinnamon, nutmeg, or even a dash of cayenne pepper for a subtle kick. This spiced variation pairs well with carrot cake, gingerbread cookies, or spiced pumpkin muffins, adding warmth and complexity to your desserts.
  5. Chunky Peanut Butter Frosting: For added texture, fold in chopped roasted peanuts into the frosting mixture before spreading or piping onto your desserts. The crunchy bits of peanuts add a delightful contrast to the creamy frosting, providing a satisfying bite with every mouthful.


  1. Can I use salted butter instead of unsalted butter in the frosting recipe? Yes, you can use salted butter, but be mindful that it may affect the overall saltiness of the frosting. Adjust the amount of additional salt in the recipe accordingly to avoid over-salting.
  2. Is it necessary to use creamy peanut butter, or can I use chunky peanut butter instead? While creamy peanut butter is traditionally used for a smooth texture, you can certainly use chunky peanut butter if you prefer a frosting with added texture. Keep in mind that the consistency may be slightly different.
  3. How can I make the frosting thicker or thinner to suit my preferences? To make the frosting thicker, add more powdered sugar. Conversely, if you prefer a thinner consistency, you can add a small amount of milk or heavy cream until you reach your desired texture.
  4. Can I make this frosting ahead of time and store it? Yes, you can make the frosting ahead of time and store it in the refrigerator for up to one week. Just make sure to store it in an airtight container to prevent it from absorbing any unwanted flavors.
