Ultimate Ermine Frosting

Ingredients:
- 1 cup (240ml) whole milk
- 1/4 cup (30g) all-purpose flour
- 1 cup (2 sticks / 225g) unsalted butter, softened
- 1 cup (200g) granulated sugar
- 1 teaspoon vanilla extract (or other flavorings of your choice)
- Pinch of salt (optional, to enhance flavor)
Instructions:
Cook the Flour and Milk Mixture:
- In a small saucepan, whisk together the milk and flour until smooth.
- Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens to a pudding-like consistency (about 5-7 minutes). Be careful not to let it burn.
- Remove from heat and let the mixture cool completely. You can speed this up by transferring it to a bowl and placing it in the refrigerator or an ice bath. Stir occasionally to prevent a skin from forming.
Cream the Butter and Sugar:
- In a large mixing bowl, beat the softened butter and sugar together on medium-high speed for 3-5 minutes, until light and fluffy. The sugar won’t fully dissolve, but it should become well incorporated.
Combine the Mixtures:
- Once the flour-milk mixture is completely cool, add it to the butter-sugar mixture one spoonful at a time, beating well after each addition. This ensures a smooth and creamy texture.
- Add the vanilla extract and a pinch of salt (if using), and continue beating until the frosting is light, fluffy, and silky smooth (about 5-7 minutes).
Use or Store:
- Use the frosting immediately to frost cakes, cupcakes, or cookies. If it becomes too soft, refrigerate for 10-15 minutes to firm up before using.
- Store any leftover frosting in an airtight container in the refrigerator for up to 5 days. Let it come to room temperature and re-whip before using.
Tips for the Ultimate Ermine Frosting:
- Flavor Variations: Add cocoa powder, citrus zest, or other extracts (like almond or lemon) to customize the flavor.
- Color: Use gel food coloring to tint the frosting for special occasions.
- Texture: If the frosting looks curdled or separated while mixing, keep beating—it will come together as the ingredients emulsify.
- Sugar Adjustment: For a less sweet frosting, you can reduce the sugar slightly, but keep in mind it’s already less sweet than traditional buttercream.
- Ermine frosting is a vintage recipe that’s making a comeback for its light, creamy texture and balanced sweetness. It’s perfect for pairing with classic cakes like red velvet or chocolate. Enjoy!
