Strawberry Ermine Frosting, or $300 frosting is a luscious frosting made with a cooked flour and milk mixture added to butter, sugar, and freeze-dried strawberry powder.
In a medium saucepan over medium heat, whisk together the milk and flour. Cook, whisking constantly, for 3-5 minutes, or until no lumps remain and the mixture thickens and resembles a very thick pudding. It should coat the back of a spoon. Remove the pan from the heat and let the mixture cool to room temperature.
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter, sugar, and strawberry powder on medium speed until light and fluffy (2-3 minutes). Stop the mixer and use a rubber spatula to scrape down the sides of the bowl.
To the bowl of the stand mixer, add the cooled milk mixture. Beat on medium-high speed until the frosting is light and fluffy (2-3 minutes), pausing to scrape down the sides of the bowl as needed.
Switch to the whisk attachment. Add vanilla and mix on high for 7-8 minutes, or until the frosting is smooth and creamy.
Notes
To make this with jello, substitute 1 (3.4 ounce) box of strawberry jello powder for the freeze-dried strawberries.
