Although the title "Flour Frosting" doesn't sound very appetizing, this frosting is very good. It is fluffy with a slight hint of dairy from the milk and is not over-sweet. This is apparently a classic frosting for red velvet cake, but since it only has 1 cup of sugar in it (and it makes plenty to frost 24 cupcakes) it is also a great option for children's birthday parties. This comes out a very light creamy color, but can be easily tinted with gel or paste food coloring. I found this recipe on a blog: Obsessed with Baking. If you don't have vanilla sugar, add a teaspoon of vanilla extract when you add the butter. If you refrigerate this frosting be sure to bring it to room temperature before serving or, like Swiss Meringue Butter Cream, the texture can be a little stiff. If you refrigerate it prior to frosting your cake and it seperates as it warms, just whip it back up for a few minutes in your mixer and it will be good to go.
