According to my family and friends, this used to be the frosting of choice for Red Velvet Cake (From Scratch) and Red Velvet Cupcakes until Cream Cheese Frosting became more popular. It goes by many names such as Cooked frosting, Boiled milk frosting, Flour frosting, Cooked roux frosting, Heritage frosting, or Mock buttercream icing. It is soft, creamy, fluffy and tastes very light and airy.
It is very different than my Best Classic American Buttercream Frosting and between the two, I like this one better. The addition of flour is the key to its velvet smooth texture. People worry that they would taste the flour, but I promise you won't taste it at all. Unlike typical frosting recipes, this one takes a bit longer to prepare but it's absolutely worth it.

Key ingredients for cooked flour buttercream
- Flour- This is truly the secret ingredient that really makes this frosting.
- Sugar- Both granulated and powder forms were used in this recipe.
- Milk- I suggest using whole milk for the creamiest texture.
- Vanilla- Adds a nice warm flavor.
- Butter- Be sure it is unsalted.
- Shortening- This adds stability to the frosting.
Variations
- Peppermint flavor- Replace vanilla extract 1 teaspoon peppermint extract.
- Rose icing- Replace vanilla extract with 1-2 teaspoon rose water or even more if you want a very strong flavor and fragrance.
- Try coconut flavor- Omit all other extracts add 1-2 teaspoon of coconut extract. If you like a slightly chunky coconut frosting, add ⅓ cup finely shredded coconut. You might need to add a little more milk to smooth out your frosting.
- Chocolate version- Add ¼ cup unsweetened cocoa powder in this recipe or you can try my Chocolate Buttercream Frosting (Ermine) which is incredible.
- Vegan option- Replace whole milk with vegan milk such as soy milk, coconut milk, almond milk. Also replace butter with more shortening.
- Add coloring- If you want your icing to be red, I have noticed Americolor's red gel color works best. It seems to have a deeper shade of red than compared to Wilton's red gel color.
How to make Ermine frosting recipe from scratch?
1. Heat ingredients in nonstick saucepan- This includes milk, flour, sugar.
2. Let this "flour pudding" mixture- Also known as "roux" to cool down completely.
3. In a separate mixing bowl- Cream together butter and sugar.
4. Add the flour mixture and vanilla extract- Mix everything together until light and fluffy.
5. Add powdered sugar- To enhance the sweetness, if you like (optional).
6. Enjoy- On cakes, cupcakes, and other desserts.
Tips and techniques
- Use clear vanilla extract- Since regular extract can discolor the frosting slightly.
- The flour mixture must have no lumps- Or else you will end up with lumpy frosting. If necessary, run the "roux mixture" through a fine mesh sieve to remove all lumps or run a hand held immersion blender through the mixture.
- To prevent lumps from forming in the flour mixture- Make sure to constantly whisk while you are cooking it.
- This frosting is not pure white- It's slightly "off-white." You can easily add white gel coloring to make it truly white frosting
- Refrigerating the frosting for 30 minutes prior to frosting will make it easier to pipe.
- Don't use liquid food coloring- Since that will thin the consistency of the frosting. Only use gel food coloring.
- I like to make it with shortening and butter together- So as to make it more stable but traditionally, it's made with all butter.
- Add powdered sugar to this frosting- To enhance the sweetness a bit and also make it thicker. Traditionally, it has no powdered sugar at all.
- If the frosting is too thin- Chill it for 30-40 minutes in the fridge. If that still doesn't work, mix in a little powdered sugar to make it thicker.
- If the frosting is too thick- Add milk a little at a time in order to thin it out.
