Ingredients

Filling

  • 1 tablespoon Dutch-process cocoa powder
  • 1 tablespoon instant espresso powder
  • 2 tablespoons granulated sugar

Cake

  • 3 sticks plus 2 tablespoons unsalted butter, room temperature
  • 1/2 cup plus 1 tablespoon Dutch-process cocoa powder
  • 3 1/4 cups all-purpose flour
  • 1 1/2 teaspoons coarse salt
  • 3/4 teaspoon baking soda
  • 1 1/2 teaspoons baking powder
  • 1 cup brewed espresso or very strong coffee
  • 1 tablespoon instant espresso powder
  • 1 cup sour cream
  • 2 1/2 cups granulated sugar
  • 4 large eggs, room temperature
  • 1 cup (5 ounces) very finely chopped bittersweet chocolate (61 percent cacao)
  • Confectioners' sugar, for dusting
  • Lightly whipped cream, for serving
  • Candied Lemon Zest, for serving (optional)

Directions

  1. Filling: Preheat oven to 325 degrees. Stir together cocoa, espresso powder, and granulated sugar.

  2. Cake: In a small bowl, mash together 2 tablespoons butter and 1 tablespoon cocoa; generously brush a 12-cup nonstick Bundt pan with mixture. In another bowl, whisk together flour, salt, baking soda, and baking powder. In another bowl, whisk brewed espresso into remaining 1/2 cup cocoa and espresso powder until smooth; whisk in sour cream.

  3. With a mixer on medium-high speed, beat remaining 3 sticks butter with granulated sugar until light and fluffy, about 2 minutes. Add eggs, one at a time, beating well after each addition. Reduce speed to low and add flour mixture in three batches, alternating with cocoa mixture in two batches. Beat to combine, scraping down bowl as needed. Beat in chopped chocolate.

  4. Transfer one-third of batter to prepared pan. Sprinkle with half of filling, avoiding edges. Repeat, then finish with remaining one-third of batter, smoothing top with an offset spatula. Bake until a tester inserted in center comes out clean, about 1 hour. Let cool in pan on a wire rack 15 minutes, then turn cake out onto rack; let cool completely, at least 2 hours.

  5. Dust with confectioners' sugar. Serve, with a dollop of whipped cream and some candied lemon zest.

    I haven't made this yet but it sounds delicious. I was wondering why butter wasn't listed on the ingredients list.

    Used 15 dollars worth of ingredients but my "standard" bundt pan was obviously too small. The batter overflowed and burned ( thank goidness I baked on a sheet tray) and took 1 hour plus 40 minutes to cook. Totally a waste of time and ingredients unless you are Martha and have huge potential nconcentional bundt pans and unlimitd ingreadients ar yr dispiasal.

    Lovely cake but I'm not sure what the point of the 'filling' is. It just adds an unpleasantly gritty, bitter stripe through the cake. I will definitely make it again but without the filling. Recipe worked perfectly, baking time was spot on (I'm in the UK and baked it at 160 C)

    Turned out perfectly, altho I did have to bake it 75 minutes. I REALLY liked the idea of preparing the bundt pan not only with butter, but with butter mixed with cocoa!
