Cooked & Whipped Buttercream Frosting

• 3 T corn starch
• 1 cup milk (or 2 T melted butter + water to make 1 c)
• 1/2 c shortening
• 3/4 c butter
• 1 c sugar
• 1 T vanilla

1. Whisk corn starch into the milk and cook in saucepan on medium heat, stirring constantly until thick. Take it off the burner and cool until about room temperature, stirring occasionally to prevent lumps.
2. Meanwhile, put sugar into a blender and blend on high speed until superfine like powdered sugar.
3. Add sugar to butter and shortening and cream together.
4. Add vanilla. Switch to the whip attachment and add the thickened corn starch mixture (you may want to blend the corn starch mixture in the blender first if it seems lumpy or you forgot to stir enough). Whip until it’s the consistency of whipped cream.
