Brown Sugar Ermine Frosting Recipe
Introduction
Brown Sugar Ermine Frosting is a classic, silky frosting with a rich caramel flavor that pairs beautifully with chocolate or spice cakes. Its smooth texture and subtle sweetness make it a delightful alternative to traditional buttercream.

Ingredients
- 1 cup (245 g) whole milk
- 5 tablespoons all-purpose flour, sifted
- 1 cup (2 sticks / 227 g) unsalted butter, room temperature
- 1 cup (200 g) light brown sugar, packed
- 1 teaspoon vanilla extract
Instructions
- Step 1: In a medium saucepan over medium heat, whisk together the milk and flour. Cook, whisking constantly, for 3-5 minutes until the mixture thickens and resembles a very thick pudding. It should coat the back of a spoon. Remove from heat and cover with plastic wrap pressed directly on the surface to prevent a skin from forming. Let it cool to room temperature.
- Step 2: In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and brown sugar together on medium speed until light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl with a rubber spatula.
- Step 3: Add the cooled milk and flour mixture to the creamed butter and sugar. Beat on medium-high speed until the frosting becomes light and fluffy, approximately 2-3 minutes, scraping down the bowl as needed.
- Step 4: Switch to the whisk attachment, add the vanilla extract, and whisk on high speed for 7-8 minutes until the frosting is smooth, creamy, and fully combined.
Tips & Variations
- Make sure the milk and flour mixture is completely cool before adding it to the butter mixture to prevent melting the butter and losing the fluffy texture.
- For a deeper caramel taste, try using dark brown sugar instead of light brown sugar.
- If you don’t have a stand mixer, a hand mixer on medium-high speed can also work well.
- This frosting pairs exceptionally well with red velvet, chocolate, or spice cakes.
Storage
Store the frosting in an airtight container in the refrigerator for up to one week. Before using, let it come to room temperature and re-whip with a mixer to restore its creamy texture. It can also be frozen for up to one month; thaw in the refrigerator before re-whipping.

The result is a light, fluffy, and creamy frosting with a rich caramel flavor from the brown sugar—perfect for cakes and cupcakes.
Ingredients
Frosting Base
- 1 cup (245 g) whole milk

Buttercream
- 1 cup (2 sticks / 227 g) unsalted butter, room temperature
- 1 cup (200 g) light brown sugar, packed
- 1 teaspoon vanilla extract
Instructions
- Whisk milk and flour. Cook. Let cool.
In a medium saucepan over medium heat, whisk together the milk and sifted flour. Continue whisking constantly for 3-5 minutes until the mixture is thickened and smooth, resembling a very thick pudding that can coat the back of a spoon.

Pour the cooled milk and flour mixture into the creamed butter and sugar. Beat on medium-high speed for 2-3 minutes until the frosting lightens and becomes fluffy. Scrape down the sides of the bowl occasionally to ensure even mixing.

Switch to the whisk attachment and add the vanilla extract. Mix on high speed for 7-8 minutes until the frosting is silky, smooth, and evenly combined.
