My Granny used to make the most incredible peanut butter cake. Actually, I think the cake was more vanilla than peanut butter but the icing… yes, it was icing and not peanut butter frosting… was poured over the cake and then dried into this incredible peanut butter fudge. The cake would often split from the heat of the icing but no one cared because it tasted incredible.
Over the years, many of us have tried to recreate that peanut butter icing and somewhere along the way, I developed this peanut butter frosting recipe.
It is not Granny’s peanut butter icing. Not even close. But it is still amazing and perfect for topping cupcakes of for using as a filling in whoopie pies, cookies, and cakes.
