For a Stronger Cream Cheese Flavor: Use an additional 4 oz. (½ block) of cream cheese. This is good for any cake/cupcake recipe that is traditionally topped with Cream Cheese Frosting, like Carrot Cake, or Red Velvet Cake. For Chocolate Frosting: (my favorite!) add ½ cup unsweetened cocoa (I use Ghirardelli brand, it’s really good). Add the cocoa powder before adding the powdered sugar, so it gets fully incorporated into the butter and cream cheese.
