Mock Whip Cream Frosting

Whisk together the flour and milk in a saucepan. Place over medium-high heat and cook, stirring constantly, until the mixture is thick like pudding. Remove from the heat and set aside to cool completely.

Combine the butter and shortening in a mixing bowl. Beat on medium-high speed with an electric mixer for 4 minutes until it is light and fluffy. Add the sugar and continue to beat for 4 more minutes.

Add the cooled milk mixture and vanilla and beat for 4 more minutes, scraping down the sides as needed.

Spread the frosting on cooled cake or cupcakes.
