"That's the Best Frosting I've Ever Had"

From The Pioneer Woman's Tasty Kitchen blog. It is a weird recipe and absolutely delicious.

Ingredients:
5 T All Purpose Flour
1 c milk
1 t vanilla
1 c butter
1 cup granulated sugar (NOT powdered sugar)

In a small saucepan, whisk flour into milk and heat, stirring constantly until it thickens. It should be very thick, like brownie batter. Remove from heat and let it cool to room temperature. It must be cool before you move to the next step. Add vanilla and stir. (you can do this while it is still warm)

Cream the butter and sugar together until light and fluffy. You don't want any graininess left. Add the completely cooled milk and flour mixture and beat the heck out of it. If it looks separated you have not beaten it enough. Beat until it all combines and resembles whipped cream.

Grab a spoon and taste this wonderful goodness. Repeat. If there is any left, you can frost a cake or cupcakes with it. Yum!
