Chocolate-glazed chocolate Bundt cake

Instructions

1. Preheat the oven to 325°F. Spray a 10-inch Bundt pan with nonstick spray.
2. To make the cake, whisk together the flour, granulated sugar, baking powder, baking soda, and salt in a medium bowl; set aside. Combine the cocoa, chopped chocolate, and espresso powder in a small bowl. Pour the boiling water over the cocoa mixture, stirring until the chocolate is melted and the mixture is smooth. Stir in the vanilla. Whisk together the buttermilk, oil, egg, and egg white in a large bowl; stir in the cocoa mixture until blended. Gradually add the flour mixture, stirring just until blended. Stir in the chocolate chips.
3. Pour the mixture into the pan. Bake until a toothpick inserted into the center comes out clean, 45 – 50 minutes. Let cool in the pan on a rack 10 minutes. Remove the cake from the pan and let cool completely on the rack.
4. To make the glaze, whisk together the glaze ingredients in a small bowl until smooth. Let stand until cool and thickened, about 15 minutes. Place the cake on a serving plate. Pour the glaze over, allowing it to drip down the side of the cake. Let stand until set, about 10 minutes. Yields 1⁄24 of cake per serving.
