Super Yummy Frosting

1 cup milk

5 Tbls flour

1 tsp vanilla

1 cup butter

1 cup sugar (granulated, NOT powdered!)

In a small saucepan, whisk flour into milk and heat, stirring constantly, until it thickens.  Remove from heat and cool to room temp.  Stir in vanilla.  Cream butter and sugar until light and fluffy. Add milk mixture and beat until combined.  (It will look a little like whipped cream.) 

I made this for Declan's birthday cake (which was chocolate) and it was VERY tasty!
