The magic of brown butter
Miss Clementine on the occasion of her second birthday. She didn't understand the concept but she wasn't a bit shy about basking in all the love coming her way during the song.
This recipe is from King Arthur Flour. I baked two batches of the cake recipe (as we were expecting a crowd) and made a caramel filling for between layers.
Brown butter adds a distinctive flavor - "The frosting tastes like Christmas," says my daughter.

Many Southern cooks use an often-tricky caramel-fudge recipe to frost their cakes; this one opts for caramel syrup throughout, for flavor and moisture, and a dependable brown-butter frosting.
Caramel Syrup
- 298g granulated sugar
- 74g water
- 170g additional water
Batter
- 361g King Arthur Unbleached All-Purpose Flour
- 248g granulated sugar
- 2 1/2 teaspoons baking powder
- 1 teaspoon salt
- 170g unsalted butter
- 227g sour cream
- 4 large eggs
- 163g caramel syrup
- 1 teaspoon vanilla extract
Frosting
- 170g unsalted butter
- 28g to 71g caramel syrup
- 2 teaspoons vanilla extract
- 1/8 teaspoon salt
- 454g confectioners' sugar
- 57g heavy cream
Directions
- To make the caramel syrup: In a small, heavy saucepan, combine the sugar with 1/3 cup water. Cook over medium heat without stirring until the sugar melts, the water boils away, and the syrup and begins to turn color.
- When the sugar is a medium amber color, remove the pan from the heat and slowly pour in 3/4 cup water. The mixture will bubble and spurt, so be careful. Once all of the water is in the pan, return the pan to low heat and stir until the sugar melts and you have a smooth liquid. Remove from the heat and cool to room temperature.
- To make the cake: Preheat the oven to 350°F. Grease two 9" cake pans, and line them with parchment.
- In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt. Add the butter and beat at low speed until the mixture looks sandy.
- Combine the 1/2 cup caramel syrup, vanilla, and sour cream; add all at once to the flour mixture, and mix until fully incorporated. Scrape the sides and bottom of the mixing bowl, then beat in the eggs, one at a time. Scrape the bowl, beat for one minute more, and divide the batter between the prepared pans.
- Bake the cakes for 25 to 27 minutes, until a light touch in the center springs back, and the cake just begins to pull from the sides of the pan. Remove them from the oven and cool them in their pans on a rack.
- To make the frosting: Place the butter in a 2-quart, heavy-bottomed saucepan. Melt over medium-low heat. Cook until the butter foams and begins to spurt; eventually the solids will begin to caramelize and the butter will begin to smell nutty. Once this happens, remove it from the heat and pour it into a mixing bowl. Let the butter cool to room temperature.
- Add the caramel syrup, vanilla, and salt. Add the confectioners' sugar and mix; the mixture will get stiff and lumpy (that's OK).
- Add the heavy cream a tablespoon at a time while the mixer is running; the frosting will magically smooth out. When the frosting is a little stiffer than you want for a spreading consistency, scrape the sides and bottom of the mixing bowl, and add one more tablespoon of cream. The icing should become smooth and quite spreadable.
- To assemble: Flip the cooled cake layers out of their pans; trim the tops to be level, if necessary. Place one layer, top down, on a serving plate. Line the plate with strips of parchment or waxed paper to keep it clean while you frost the cake.
- Spread 2/3 cup of frosting over the first layer. Place the second layer, top side down, over the filling. Cover the top and sides of the cake with the remaining frosting.
- To garnish: Take thickened caramel syrup (see baker's tips, above left), cooled to room temperature, and drizzle it over the top of the cake before cutting.
- Yield: 1 cake, 16 servings.
Tips from our bakers
- To make a decorative caramel drizzle, double the amounts for the caramel syrup. Reserve half; to make that half of the syrup thicker, cook until it has a thick, syrupy consistency before cooling it to room temperature. Artfully drizzle thickened caramel over the top of the finished cake, allowing it to cascade down the sides.
