    This bakery-style peanut butter cream cheese buttercream frosting is light and creamy with a delicious melt-in-your-mouth texture. Use it to frost your favorite cake or cupcakes.

    This cream cheese/ buttercream blend pairs perfectly with my Moist and Fudgy Chocolate Cupcakes for the most delicious light and moist Peanut Butter Cup Cupcakes.

    It's amazing with my Chocolate Peanut Butter Cake!

    How to Make It

    This recipe starts just like my Vanilla Bakery Buttercream, but we'll be adding creamy peanut butter and some heavy cream to balance the texture of the peanut butter and create a light and fluffy frosting.

    It has just the right amount of cream cheese, which gives this frosting a super smooth and creamy texture, but the cream cheese flavor doesn't overpower the peanut butter flavor.

    After adding the heavy cream, beat the frosting on high for 2-3 minutes, which whips air into it and makes it nice and fluffy and silky smooth.

    This melt-in-your-mouth "bakery-style" peanut butter cream cheese frosting from Amycakes Bakery is light, creamy and delicious. Use it to frost your favorite cake or cupcakes.
    A 1x batch will frost and fill one 6" three-layer cake or about 14 cupcakes generously and a 2x batch will frost and fill one 8" three-layer cake or about 28 cupcakes generously.

    Equipment

    Mixer
    kitchen scale
    18 inch Disposable Frosting Bag
    offset icing spatula
    1M Star Tip
    Turntable

    Ingredients

    • 4 ounces Cream Cheese
    • 1 ½ sticks (6 ounces) Salted Butter (at room temperature)
    • 48 grams (¼ cup) butter flavored shortening (you may also use regular or substitute with equal parts butter)
    • 455 grams (3 ½ cups) powdered sugar
    • 128 grams (½ cup) Creamy Peanut Butter
    • 1 Tablespoon Pure Vanilla Extract
    • ¼ cup Heavy Cream
    • (optional) 1 Tablespoon Instant Clearjel (You can add this if you would like a thicker, more stabilized frosting. See notes section.)

    Instructions

    • Whisk the powdered sugar and Instant Clearjel (if using) together until well-blended. Set aside.
    • Using a stand mixer (preferred) or handheld mixer and a large bowl, beat the cream cheese until broken up and softened.
    • Add the room temperature salted butter and continue to beat until there are no lumps, scraping the sides of the bowl as needed.
    • Add the shortening and beat and scrape the sides until the mixture is smooth without lumps.
    • While the mixer is on low, slowly add the powdered sugar mixture. It will be thick, but continue to beat on low until it is well incorporated.
    • Add the peanut butter and pure vanilla and mix on medium speed until well-blended, scraping the sides of the bow as needed. Then while the mixer is on low, pour in the heavy cream.
    • Beat the peanut butter buttercream on high for two-three minutes. This will add air into the buttercream and make it light and fluffy.
    • This buttercream is best served at room temperature. If you aren't serving it within 24 hours, refrigerate it, but remove it from the fridge a couple of hours before using so that it may come back to room temperature before frosting cakes, cupcakes, or serving.

    Notes

    Read my article Instant Clearjel: a Magical Little-Known Bakery Ingredient to see why I think this ingredient is worth having in your pantry.  Instant Clearjel must always be whisked thoroughly with other dry ingredients before being added to wet ingredients to avoid clumping.  If you don’t have Instant Clearjel you can simply leave it out completely, this frosting is delicious without it and has a light silky texture.  If you need a thicker frosting, you can add a little bit more powdered sugar.

      Hi! I love all of your recipes! I made the strawberry cake and was fantastic! I was wondering, what it the perfect cake box to put the cakes in? so they can be transported safely? Thank you!

        So glad you enjoyed the recipe! 🙂 a 10x10x6" box is the size I use for 8" cakes. Depending on the height of your cakes, you may also be able to a 10x10x5" tall box. These work well when using a 10" cake board, so that the cake doesn't slide around in the box.
