I baked a batch of Red Velvet Cupcakes (recipe found here) recently for my nephew's first month baby shower and had frosted the cupcakes with Cream Cheese Swiss Meringue Buttercream.
For normal frostings on cakes and cupcakes, I will use the Swiss Meringue Buttercream (SMBC) recipe here. However, for red velvet cakes, I will add in whipped cream cheese to my SMBC have a Cream Cheese Swiss Meringue Buttercream.
I'm not a big fan of cupcakes frosted with buttercream as they are just way far too sweet for my liking. However, when the need arises, I'll use the Swiss Meringue Buttercream (SMBC) recipe below shared by a friend to frost cakes and cuppies.
