What Is Ermine Frosting?
Ermine frosting (also called boiled milk frosting or flour buttercream) is a classic recipe that dates back to the early 1900s. It was originally used on red velvet cake before cream cheese frosting became popular.
The magic lies in its unique base: a cooked mixture of milk and flour that transforms into a smooth, fluffy, cloud-like frosting when whipped with butter and sugar.

How to Make Ermine Frosting (Step-by-Step)
Step 1: Cook the Flour Mixture
In a saucepan over medium heat, whisk together the milk and flour. Cook until the mixture thickens into a pudding-like consistency. This usually takes about 5–7 minutes.
👉 Tip: Stir constantly to avoid lumps.
Step 2: Cool Completely
Remove from heat and let the mixture cool to room temperature. For best results, cover it with plastic wrap touching the surface to prevent a skin from forming.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter and sugar together until light and fluffy. This step is key to achieving that signature silky texture.
Step 4: Combine and Whip
Gradually add the cooled flour mixture to the butter mixture while beating continuously. Add vanilla extract and whip until the frosting becomes light, airy, and smooth.
Pro Tips for Perfect Ermine Frosting
