There's something magical about the combination of peanut butter and chocolate, and this frosting delivers that classic pairing with an unexpectedly airy texture. Unlike dense, heavy peanut butter icings that can overwhelm a cake, this version whips up remarkably light thanks to the extended beating time and careful balance of cream. The result is a frosting that spreads like a dream and practically melts on your tongue, making it perfect for layering between chocolate cake rounds or piping onto cupcakes.

The key to achieving that signature fluffiness lies in two crucial steps: first, beating the butter and peanut butter together until they're noticeably paler in color, which incorporates air into the base, and second, not skimping on the final whipping time after adding the liquid. Those extra minutes make all the difference between a good frosting and an extraordinary one. Pay attention to the consistency as you add cream—you want it spreadable but still able to hold its shape, so add that final tablespoon only if truly needed.

While this frosting is a natural match for chocolate cakes and brownies, don't overlook its potential on banana cupcakes or swirled into vanilla buttercream for a marbled effect. For a fun twist, fold in mini chocolate chips or chopped peanut butter cups after whipping. The recipe makes enough to generously frost a two-layer cake or about two dozen cupcakes, and it holds up beautifully at room temperature for several hours.

Instructions

In a large mixing bowl, beat the softened butter and peanut butter with an electric mixer (wire whisk attachment if using a stand mixer) on medium-high for 1-2 minutes, until smooth, pale, and fluffy.
With the mixer on low, gradually add the powdered sugar and beat until combined.
Add the vanilla, 2 tablespoons of heavy cream, and salt. Beat on medium-high for another 2-3 minutes until light and fluffy. If the frosting is too thick to spread easily, add another tablespoon or two of cream and beat briefly, adding additional liquid only if necessary.
