That's the Best Frosting I've Ever Had
5 Tablespoons flour1 cup milk
1 teaspoon vanilla
1 cup butter (2 sticks)
1 cup granulated white sugar (not powdered sugar)
In a small saucepan, whisk flour into milk and heat, stirring constantly, until it thickens. It took me around 5 minutes. Be careful not to burn it. Remove from heat and let it cool to room temperature. You can place the saucepan over ice in the sink for about 10 minutes or so until the mixture cools if you are in a hurry. Stir in vanilla. This mixture must be completely cooled in order for the frosting to work.
While the mixture is cooling, cream the butter and sugar together until light and fluffy. Then add the cooled milk/flour/vanilla mixture and beat until it all combines and resembles whipped cream. Make sure you scrape down the sides every so often so that it all gets incorporated and whipped. If it's not looking like whipped cream, keep on whipping. This frosting is great for piping.
