Ermine buttercream starts with a cooked flour-and-milk paste that's cooled and whipped into butter and sugar, yielding a light, satiny frosting reminiscent of whipped cream. Also called boiled milk frosting, it's a classic choice for red velvet cake because it isn't cloying and pipes cleanly. The cooking step takes a bit of patience, but the payoff is a smooth, non-gritty texture.
Ingredients
- 1 cup granulated sugar
- 1/4 cup all-purpose flour
- 1 cup whole milk
- 1 pinch salt
- 1 1/2 cups unsalted butter, softened
- 2 teaspoons vanilla extract
Method
-
In a 6-quart saucepan, whisk together the sugar, flour, and salt until no lumps remain.
-
Gradually whisk in the milk, working out any lumps, then set the pan over medium heat.
-
Cook, whisking constantly, until the mixture thickens into a thick pudding-like paste that mounds on the whisk, 8 to 10 minutes.
-
Scrape the paste into a heatproof bowl, press plastic wrap directly onto the surface, and cool completely to room temperature, about 1 hour.
-
In a stand mixer fitted with the paddle attachment, beat the softened butter on medium-high speed until pale and fluffy, about 3 minutes.
-
Switch to the whisk attachment and add the cooled flour paste to the butter one large spoonful at a time, beating well after each addition.
-
Add the vanilla extract and beat on medium-high speed until the frosting is light, fluffy, and resembles whipped cream, 5 to 7 minutes.
-
Use immediately to frost cake or cupcakes, or refrigerate in an airtight container and re-whip before using.
