Step-by-Step Instructions
- Melt 1 cup of unsalted butter in a medium saucepan over medium heat, stirring constantly for 5-6 minutes until it turns golden brown and releases a nutty aroma. Transfer to a bowl and allow to cool for 45 minutes.
- Preheat your oven to 350°F (175°C) and grease and line two 9-inch round cake pans with parchment paper. Whisk together 2 cups of all-purpose flour, 1.5 cups of granulated sugar, 1 tablespoon of baking powder, and 0.5 teaspoon of fine salt.
- Pour in the cooled brown butter and mix until just combined.
- Add 4 egg whites, 1 cup of full-fat sour cream, 0.5 cup of vegetable oil, and 2 teaspoons of vanilla extract. Mix until well-blended and smooth.
- Divide the batter evenly between the prepared cake pans and bake for 33-35 minutes, or until a toothpick comes out with moist crumbs. Let the cakes cool in the pans for 10 minutes before transferring to wire racks.
- In a mixing bowl, beat together the remaining brown butter (0.25 cup), 8 ounces of cream cheese, 1 teaspoon of vanilla extract, and 0.25 teaspoon of salt until smooth. Gradually add 4 cups of powdered sugar and 0.25 cup of heavy whipping cream.
- Assemble by placing one layer on a serving plate. Spread frosting on top, stack the second layer, and coat the cake with remaining frosting. Optional: sprinkle turbinado sugar on top.
- Slice and enjoy your beautiful brown butter cake.

Notes
Use room temperature ingredients for a fluffier cake. Watch brown butter carefully to avoid burning. Level cake layers for a professional finish.
