The recipe was not a Pinterest one, and in truth I have no idea who to credit. It was a person named RLI R on a Yahoo Answers board. Whoever you are RLI R, you saved the day! :)
Here is the recipe...
1 cup milk
1/4 cup flour
1 cup butter(2 sticks) at room temp
1 cup granulated(regular) sugar
2 tsp Vanilla
Combine milk and flour in a small saucepan over medium heat, stirring constantly, until mixture boils and thickens. Remove from heat and cool to room temperature.
Cream the butter and sugar until very fluffy. Add the vanilla and cooled flour mixture. Continue to beat at medium speed until frosting is very fluffy and sugar is completely dissolved. (If you take a little of the frosting and rub it between your thumb and pointer finger, you'll be able to tell if the sugar has completely dissolved. If it hasn't, just keep beating.
Makes 3 cups. Enough to fill, border, and frost a 9 inch cake.(I had tons left over since ours was just 24 cupcakes!
Look at that proud face! :)
Try it! Its just as good as confectioners recipes! I honestly couldn't tell the difference, but I am not a professional. It worked great and we enjoyed our treat! What more could one ask? :)
