Ingredients
Method
- In a saucepan over medium heat, stir sugar and water until dissolved. Boil without stirring for 8 to 10 minutes until deep amber. Remove from heat, stir in 6 tbsp butter, then whisk in warm cream and salt. Cool completely.
- Preheat oven to 350°F. Grease two 8-inch pans. Whisk flour, baking powder, baking soda, and salt. Beat 1/2 cup butter and 1 cup sugar until fluffy, then beat in eggs, vanilla, and dissolved espresso. Alternate adding dry ingredients and buttermilk, then stir in cooled coffee. Divide batter between pans.
- Bake 25 to 28 minutes until a toothpick comes out with moist crumbs. Cool in pans 10 minutes, then turn out onto a rack and cool completely.
- Beat 1 cup butter until creamy. Sift in powdered sugar and cocoa, beat on low, then add dissolved espresso and cream. Whip on medium-high 3 to 4 minutes until light.
- Place one cake layer on a plate, spread with half the caramel sauce, top with a cup of buttercream. Add second layer, frost the whole cake with remaining buttercream. Chill briefly if soft.
- Drizzle remaining caramel over the top, slice with a warm knife, and serve.
Notes
For the cleanest slices, chill the assembled cake for 15 minutes before cutting. You can make the caramel sauce up to 3 days ahead and keep it in the fridge; bring it to room temperature or warm gently before using.
