The Best Buttercream Frosting
- 4 tablespoons all-purpose flour
- 1 cup milk
- 1 cup butter, softened
- 1 cup white sugar
- 1 teaspoon vanilla extract (or any flavor extract--lemon is very good)
In small saucepan, whisk the flour and the milk until smooth. Place over medium heat and cook until thick and bubbly, whisking the entire time. Place thickened mixture in a small bowl and cover with plastic wrap. Allow it to cool to room temperature (do not refrigerate).
In the bowl of a stand mixer (I swear by my KitchenAid!), combine the butter and the sugar. Beat with the paddle attachment (those new ones that scrape the sides of the bowl are perfect)on high speed for about 10 minutes. Add the cooled flour mixture and beat for an additional 15 minutes, or until the frosting is smooth with no gritty sugar. At this point, stir in whatever flavor extract you prefer and maybe a bit of food coloring if you want to be festive. ;)
