Frosting
To make frosting, combine the Neufchatel cheese and butter with mixer until smooth and fluffy. Add confectioner’s sugar, vanilla, cinnamon and whiskey. Beat until creamy and fluffy. Taste and add more vanilla or cinnamon to taste. If it’s too thin, add more confectioner’s sugar. Put in a piping bag and use to frost cupcakes. We drizzled with caramel sauce. Store covered in refrigerator.
