Ingredients
Method
- Whisk the flour, both sugars, cocoa powder, baking soda, baking powder, cinnamon, cayenne, and salt in a large bowl until no lumps remain.
- Make a well in the center and add the eggs, buttermilk, oil, vanilla, and hot coffee. Whisk until smooth and glossy, about 1 minute.
- Pour the batter into a greased 9x13-inch metal baking pan. Bake at 350°F (175°C) for 30 to 35 minutes, until a toothpick comes out with moist crumbs. Cool in the pan on a wire rack.
- Melt the chocolate chips and heavy cream over a double boiler, stirring until smooth. Remove from heat and stir in a pinch of cinnamon and salt.
- Pour the glaze over the barely warm cake, spread it gently, and let it set for about 10 minutes before slicing.
Notes
The cake tastes even richer after a day, so baking it the night before is a good move. If you want a little crunch, scatter a handful of toasted pecans over the glaze before it sets.
