Thank Delicious Peanut Butter Buttercream filling recipe 🚨 This is a very simple recipe and it tastes just like peanut butter but it’s smoother and perfect for a cake filling. I used Italian Meringue Buttercream which is less sweet and gives it the right amount of sweetness.This is the filling I paired with the cinnamon cake, it was my son’s request. I know I t sounds like a strange combination but it was a nice surprise to see they were good together. Save this recipe and tell me if you try it
