Buttercream is one of the perfect places to infuse flavor when making a cake. Or any dessert that can use buttercream. Caramel buttercream seemed like a no brainer for a caramel inspired dessert. I used a cream based caramel for this recipe because it incorporated into the buttercream better than a tackier caramel would. This recipe took longer to make than an average buttercream recipe solely because the caramel had to chill after being cooked. This recipe is incorporated into my Great British Bake Off Challenge Week Four Showstopper!
