Fudgy Chocolate Bundt Cake

Method

1. 1

   Cake

2. 2

   Place a rack in middle of oven and preheat to 325°. Coat pan with nonstick vegetable oil spray, making sure to cover every crevice. Vigorously whisk 2 cups (250 g) all-purpose flour, 2 cups (400 g) granulated sugar, 2 tsp. Diamond Crystal or 1¼ tsp. Morton kosher salt, and 1 tsp. baking powder in a large bowl to combine.

3. 3

   Whisk 1 cup hot brewed coffee, ¾ cup (63 g) Dutch-process cocoa powder, and ½ cup (1 stick) unsalted butter, cut into small pieces, in a medium mixing bowl until cocoa is dissolved and butter is melted, about 1 minute. Add 2 large eggs, ½ cup sour cream, ½ cup vegetable oil, and 1 Tbsp. vanilla bean paste or vanilla extract and whisk until smooth. Add to dry ingredients and whisk gently until smooth. Scrape cake batter into prepared pan.

4. 4

   Bake cake until top springs back when gently pressed and a toothpick or other tester inserted into the center comes out with a few moist crumbs attached, 50–60 minutes. Transfer pan to a wire rack and let cake cool in pan 10 minutes. Run a small offset spatula around edges of cake if needed to loosen and invert cake pan onto rack. Let cake cool completely.

   Chocolate glaze and assembly

6. 6

   While the cake is cooling, microwave 4 oz. semisweet chocolate, chopped, or semisweet chocolate chips, 6 Tbsp. unsalted butter, and a large pinch of kosher salt in a medium microwave-safe bowl on high in 15-second bursts, stirring after each, until chocolate and butter are melted, about 30 seconds total. (Alternatively, heat in a heatproof bowl set over a small saucepan of simmering water, stirring often, until melted; do not let bowl touch water.) Let chocolate mixture cool, stirring occasionally, until thickened to a glaze consistency (it should thickly coat a spoon), about 30 minutes, depending on ambient temperature.

7. 7

   Drizzle glaze over cooled cake, letting it run down the sides. Sprinkle with flaky sea salt if desired. Let cake sit until glaze is set, at least 30 minutes. Do Ahead: Cake can be made 2 days ahead. Store loosely covered at a cool room temperature. Cooks’ note: If you don’t have a 12-cup Bundt pan, divide the batter between two 8½x4½" loaf pans. The bake time will be the same. Head this way for more of our favorite birthday cake recipes →
