If you enjoy baking with bold, warm flavors, this cake is an easy way to showcase brown butter’s unique character.
Ingredients for Brown Butter Snack Cake
You don’t need many ingredients to make this cake. The list below covers what you’ll use for both the cake and the frosting.
- Butter: Used in the cake batter and to make the brown butter buttercream.
- Sour cream: Keeps the cake moist and adds a subtle tang. You can substitute equal parts Greek yogurt.
- Milk: Whole milk yields the best texture, but lower-fat or plant-based milks work in a pinch.
- Egg whites: Using only whites keeps the crumb light and delicate.
- Vanilla: The recipe uses both vanilla extract and vanilla bean paste for depth; use 1½ tablespoons of whichever you have if needed.
- Granulated sugar: Keeps the brown butter flavor prominent.
- All-purpose flour: Tested to give consistently good results; feel free to try cake flour but expect slight texture differences.
- Baking soda & baking powder: Provide lift and a tender crumb.
- Fine sea salt: Balances sweetness and enhances flavor.
- Powdered sugar: For the frosting.
- Heavy cream: Adds richness to the frosting; you can substitute milk if needed.
What is Brown Butter?
Brown butter, or beurre noisette in French, is simply butter that’s been melted and cooked until the milk solids brown. Those toasted solids give the butter a nutty, caramel-like aroma and a golden color. The flavor is richer and more complex than plain melted butter, which is why brown butter is such a powerful way to upgrade cakes, cookies, sauces, and more. You’ll often rely on both sight (golden flecks) and smell (a warm, nutty note) to know it’s ready.
How to Make Brown Butter
Making brown butter is quick and straightforward. A light-colored pan helps you see the browning more clearly.
- Melt: Cube unsalted butter and melt it over medium-low to medium heat, stirring occasionally.
- Stir as it foams: When the butter begins to foam, stir more frequently so the milk solids don’t burn as they sink and brown on the pan bottom.
- Watch for color and aroma: After a few minutes the solids will turn golden brown and the butter will smell nutty. Remove from heat immediately.
- Cool or re-solidify depending on use: Transfer the brown butter to a heatproof bowl. For the cake batter let it cool toward room temperature while still liquid. For frosting, chill the brown butter until solid, then whip it back to a spreadable consistency.

FREQUENTLY ASKED QUESTIONS
How should I store the cake?
Store the finished cake in an airtight container in the refrigerator. It will stay fresh for up to five days. Bring slices to room temperature for 20–30 minutes before serving for best texture and flavor.
Why are measurements in grams?
Grams provide more consistent, reliable results than volume measurements. The recipe is developed in grams for precision, but some recipe cards offer a US customary conversion if you prefer cup measures.
TROUBLESHOOTING
My cake turned out dry. Why?
Dry cake usually results from too much flour or overbaking. Use a kitchen scale for accuracy, and check the cake toward the end of the suggested bake time. Remove when a toothpick comes out clean or with a few moist crumbs.
The cake sank in the middle. What happened?
Slight settling as the cake cools is normal, but significant sinking often means it was underbaked or had too much leavening. Ensure the center is fully set before removing from the oven and measure leavening agents carefully.

Instructions
For the Brown Butter Snack Cake:
-
Cube the butter and place it in a light-colored skillet. Melt over medium heat, stirring constantly so the milk solids brown evenly.
-
As the butter melts it will foam. Continue stirring; after 5–8 minutes small browned specks will form and a nutty aroma will develop. Remove from heat and pour into a heatproof bowl to cool for about 10 minutes.
-
Preheat the oven to 350°F (180°C) and grease an 8×8-inch pan or line it with parchment.
-
To the still-liquified brown butter add sour cream, milk, egg whites, vanilla extract, and vanilla bean paste; whisk to combine. Add sugar and whisk again until smooth.
-
Sift in the flour, baking soda, baking powder, and salt. Mix until just combined.
-
Pour the batter into the prepared pan and smooth the top. Bake 28–30 minutes, or until a toothpick inserted into the center comes out clean with a few moist crumbs. Cool completely before frosting.
To Make the Brown Butter Frosting:
-
Cube the butter and brown it using the same method as above. Once browned, pour into a heatproof bowl and chill until solidified, about 20 minutes.
-
In a mixer fitted with the paddle or using a hand mixer, beat the solidified brown butter on medium-high until smooth and creamy. Add powdered sugar, heavy cream, and vanilla bean paste. Beat on low for 30 seconds, then on high for 2 minutes. Adjust salt to taste and add optional coloring if desired.
