Ingredients

For the $300 Frosting

• 1 cup (240 ml) 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

Ingredient Notes

Milk: Whole milk is recommended for a rich, creamy texture, although other types of dairy milk can work.

All-purpose flour: Thickens the milk into a smooth cooked base. Be sure to whisk thoroughly to prevent lumps.

Unsalted butter: Provides the frosting’s rich flavor and fluffy structure. Use softened butter, not melted butter.

Granulated sugar: Sweetens the frosting without requiring powdered sugar. Proper whipping helps dissolve the sugar crystals.

Vanilla extract: Adds a warm, classic flavor that pairs beautifully with many cakes.

How to Make the $300 Frosting Recipe

Step 1: Prepare the Milk and Flour Mixture

In a medium saucepan, whisk together the milk and all-purpose flour until completely smooth.

Make sure there are no visible lumps before turning on the heat.

Place the saucepan over medium heat and cook for approximately 5–8 minutes, whisking constantly.

As the mixture heats, it will gradually thicken into a smooth, pudding-like paste.

Once thickened and the flour has cooked through, remove it from the heat.

Step 2: Cool the Mixture Completely

Transfer the cooked milk mixture to a shallow bowl.

Cover the surface directly with plastic wrap to prevent a skin from forming.

Allow it to cool completely to room temperature, approximately 30 minutes, although a larger batch or warmer kitchen may require more time.

The mixture should no longer feel warm before combining it with the butter.

This step is essential because a warm base can melt the butter and cause the frosting to become runny.

Step 3: Cream the Butter and Sugar

In a large mixing bowl, combine the softened unsalted butter, granulated sugar, and vanilla extract.

Using a hand mixer or stand mixer fitted with the paddle attachment, beat on medium-high speed for approximately 5 minutes.

The mixture should become noticeably lighter in color and fluffy.

Scrape down the sides of the bowl occasionally to ensure even mixing.

Step 4: Add the Cooled Milk Mixture

With the mixer running on medium speed, gradually add the completely cooled milk-and-flour mixture.

Add it one spoonful at a time, allowing each addition to incorporate before adding more.

Continue mixing until the frosting becomes smooth and creamy.

Step 5: Whip Until Light and Silky

Increase the mixer speed to medium-high.

Beat for another 5 minutes, or until the frosting is fluffy, silky, and well combined.

Taste a small amount. If it still feels grainy from the sugar, continue whipping for several more minutes.

The finished frosting should be light, creamy, and smooth enough to spread easily.

Step 6: Frost and Serve

Spread the frosting over completely cooled cakes or cupcakes using an offset spatula.

You can also transfer it to a piping bag fitted with your favorite decorating tip.

For the best texture, use the frosting soon after preparing it.

Tips for Perfect Ermine Frosting

Cool the cooked base completely. Even a slightly warm milk mixture can soften or melt the butter, making the frosting loose.

Use softened butter. The butter should be pliable but not greasy or melted.

Whisk the flour and milk before heating. Starting with a smooth mixture helps prevent lumps.

Cook until thick. The milk mixture should resemble a thick pudding or paste rather than a thin sauce.

Whip thoroughly. Extended mixing is important for achieving the light, fluffy texture and reducing sugar graininess.

Use room-temperature ingredients. Butter and the cooked base should be at similar temperatures to help the frosting emulsify properly.

Avoid over-warming. Ermine frosting is butter-based and can soften quickly in hot environments.

Use a clean mixing bowl. A clean, dry bowl helps produce a consistent frosting.

Delicious Frosting Variations

Chocolate $300 Frosting

Add ¼ cup of sifted unsweetened cocoa powder to the butter mixture for a chocolate version.

You may need a small splash of milk to adjust the consistency.

Strawberry Ermine Frosting

Beat in 2–3 tablespoons of finely ground freeze-dried strawberry powder for natural strawberry flavor and a soft pink color.

Lemon Vanilla Frosting

Add 1 teaspoon of finely grated lemon zest and a little lemon extract for a bright citrus flavor.

Almond Ermine Frosting

Replace half of the vanilla extract with almond extract for a delicate almond flavor.

Coffee Frosting

Dissolve 1 teaspoon of instant espresso powder in a very small amount of warm water, let it cool, and beat it into the frosting.

Coconut Frosting

Add ½ teaspoon of coconut extract for a tropical-inspired variation.

What to Serve with $300 Frosting

• Classic vanilla cake
• Moist chocolate cake
• Red velvet cake
• Yellow birthday cake
• Homemade cupcakes
• Strawberry cake

One particularly delicious combination is a rich chocolate layer cake topped with this light vanilla frosting. The contrast between the deep chocolate flavor and delicate buttercream creates a wonderful balance.

How to Store $300 Frosting

Refrigerator

Transfer leftover frosting to an airtight container.

Store in the refrigerator for up to 5 days.

Before using, allow it to soften slightly at room temperature, then beat briefly with a mixer to restore its fluffy consistency.

Freezer

For longer storage, place the frosting in a freezer-safe airtight container.

Freeze for up to 2 months for best quality.

Thaw overnight in the refrigerator, then allow it to soften and rewhip before using.

Room Temperature

Because this frosting contains a cooked milk base, refrigerate it when not being served.

Avoid leaving frosted desserts at room temperature for more than 2 hours, especially in warm conditions.

Frequently Asked Questions

What is $300 frosting?

The $300 frosting is a popular name for an old-fashioned cooked flour frosting, commonly called ermine frosting. It uses milk, flour, butter, sugar, and vanilla to create a fluffy, silky topping.

Why is it called $300 frosting?

The name is associated with stories about an unusually valuable frosting recipe. However, the exact origin of the name and the claim that the recipe sold for $300 are not reliably documented.

Is $300 frosting the same as ermine frosting?

Yes. This recipe follows the basic method used for traditional ermine frosting, which combines a cooked milk-and-flour mixture with whipped butter and sugar.

Is ermine frosting sweeter than buttercream?

Ermine frosting generally tastes less intensely sweet than traditional American buttercream, making it a good choice for people who prefer a lighter frosting.

Why is my frosting grainy?

Graininess usually comes from granulated sugar that hasn’t fully dissolved. Continue beating the frosting to help smooth the texture. If it remains noticeably grainy, the sugar may need to be dissolved in the cooked milk mixture in a future batch.

Why did my frosting turn runny?

Runny frosting can happen when the cooked milk mixture is still warm or the butter becomes too soft. Refrigerate the frosting briefly, then whip again once it has firmed up.

Can I use powdered sugar instead of granulated sugar?

Traditional ermine frosting is made with granulated sugar. Powdered sugar changes the texture and sweetness, so it isn’t a direct one-to-one substitute for this method.

Can I pipe decorations with this frosting?

Yes. Properly whipped ermine frosting can hold simple piped swirls, borders, and cupcake decorations. For intricate designs, chill it briefly if it becomes too soft.

Can I make $300 frosting ahead of time?

Absolutely. Prepare it in advance, refrigerate it in an airtight container, and rewhip before decorating.

Does $300 frosting need to be refrigerated?

Yes. Refrigeration is the safest general storage recommendation because the frosting contains dairy and a cooked milk mixture.
