This frosting doesn't have alcohol in it, but it's not simply a browned butter frosting. You may want to double this recipe if you are like me and use a lot on each cupcake!
Mix the two butters alone for approximately one minute. This incorporates the two types of butter together and makes them fluffy.
Carefully pour in the sugar, 1 cup at a time, until mixed thoroughly.
Add in the cream, using only enough to achieve the proper consistency.
