Vintage Ermine Frosting

Vintage Ermine Frosting: The Classic Bakery Frosting That's Light, Silky, and Not Too Sweet

Before buttercream became the standard frosting for celebration cakes, many home bakers relied on a recipe known as Ermine Frosting. Also called boiled milk frosting, flour frosting, or heritage frosting, this old-fashioned favorite is prized for its silky texture, delicate sweetness, and light, whipped consistency.

Unlike traditional American buttercream, which is made primarily with butter and powdered sugar, ermine frosting starts with a cooked milk-and-flour paste. Once cooled and whipped with butter and sugar, the mixture transforms into a smooth, creamy frosting that's rich without being overly sweet.

This timeless recipe is especially popular for frosting classic layer cakes, cupcakes, and the traditional Red Velvet Cake.

Why You'll Love Ermine Frosting

Ermine frosting has remained a favorite for generations because it offers:

• A light, fluffy texture.
• A smooth, silky finish.
• Less sweetness than powdered sugar buttercream.
• Excellent spreadability for cakes and cupcakes.
• A delicate vanilla flavor that complements many desserts.

Its whipped consistency makes it ideal for anyone who finds traditional buttercream too heavy or overly sugary.

Yield

Makes approximately 4 cups, enough to frost:

• One two-layer 8- or 9-inch cake
• About 24 cupcakes

Ingredients

For the Frosting

• 1 cup (240 ml) whole milk
• 5 tablespoons (40 g) all-purpose flour
• 1 cup (226 g) unsalted butter, softened
• 1 cup (200 g) granulated sugar
• 1 teaspoon pure vanilla extract
• Pinch of salt (optional)

Equipment

You'll need:

• Small saucepan
• Whisk
• Heatproof bowl
• Stand mixer or hand mixer
• Rubber spatula

Step-by-Step Instructions

Step 1: Make the Flour Paste

In a small saucepan, whisk together the milk and flour until completely smooth with no lumps remaining.

Step 2: Cook the Mixture

Place the saucepan over medium heat, whisking constantly.

Continue cooking until the mixture thickens into a pudding-like consistency and begins to bubble gently.

It should be thick enough to coat the back of a spoon.

This usually takes about 5–7 minutes.

Step 3: Cool Completely

Transfer the cooked paste to a heatproof bowl.

Press plastic wrap directly onto the surface to prevent a skin from forming.

Allow it to cool completely before continuing.

You can:

• Leave it at room temperature for 1–2 hours, or
• Refrigerate for 30–45 minutes, stirring occasionally.

The paste must be completely cool before mixing with the butter.

Step 4: Cream the Butter

Using a stand mixer or hand mixer, beat the softened butter for 3–5 minutes until it becomes pale, light, and fluffy.

Step 5: Add Sugar and Vanilla

Gradually beat in:

• Granulated sugar
• Vanilla extract
• Salt (if using)

Continue mixing for another 2–3 minutes until the mixture becomes airy and most of the sugar has dissolved.

Step 6: Add the Flour Paste

Reduce the mixer speed to medium-low.

Add the cooled flour paste one tablespoon at a time, allowing each addition to blend completely before adding more.

Step 7: Whip Until Fluffy

Once all the paste has been incorporated, increase the mixer speed to medium-high.

Beat for 5–7 minutes.

The frosting will become:

• Silky
• Smooth
• Light
• Airy
• Similar in texture to whipped cream but more stable

If necessary, scrape down the bowl during mixing.

Step 8: Taste and Adjust

Taste the frosting.

If you'd like a stronger vanilla flavor, add a little more vanilla extract.

If the frosting feels too soft, refrigerate it for 15–20 minutes, then whip it again until fluffy.

Step 9: Frost Your Cake

Use immediately to frost:

• Layer cakes
• Cupcakes
• Sheet cakes
• Cookies
• Snack cakes

Its smooth consistency also makes it easy to pipe decorative swirls and borders.

Storage

Room Temperature

Store in an airtight container for up to 2 days if your kitchen is cool.

Refrigerator

Refrigerate for 5–7 days.

Before using:

1. Bring to room temperature.
2. Re-whip for several minutes until light and fluffy.

Freezer

Freeze in an airtight container for 2–3 months.

When ready to use:

• Thaw overnight in the refrigerator.
• Let it come to room temperature.
• Beat again until smooth and airy.

Tips for Perfect Ermine Frosting

• Make sure the flour paste is completely cool before adding it to the butter.
• Use room-temperature butter for the smoothest texture.
• Beat the frosting long enough to incorporate air—it becomes noticeably lighter as it whips.
• If the frosting appears separated, continue beating; it often comes together after several more minutes.
• For chocolate ermine frosting, whisk cocoa powder into the milk-and-flour mixture before cooking.

Best Cakes to Pair With Ermine Frosting

This frosting complements many classic desserts, including:

• Red Velvet Cake
• Yellow Butter Cake
• Chocolate Cake
• White Cake

• Spice Cake

Its mild sweetness allows the flavor of the cake itself to shine.

A Bit of History

Ermine frosting dates back to the early 20th century and was a staple in American home baking long before powdered sugar buttercream became commonplace. Because it uses a cooked flour-and-milk base instead of large amounts of confectioners' sugar, it delivers a lighter texture and a more subtle sweetness.

It became especially well known as the traditional frosting for Red Velvet Cake, offering a creamy finish that balanced the cake's rich flavor without overpowering it.

Conclusion

Vintage Ermine Frosting is proof that some of the best recipes stand the test of time. With its silky texture, delicate vanilla flavor, and balanced sweetness, it remains a wonderful alternative to traditional buttercream. Whether you're baking a special occasion cake or simply want to try a classic recipe from generations past, this old-fashioned frosting is sure to become a favorite in your kitchen.
