Instructions
Position oven racks in the middle and preheat to 350°F (177°C). Grease two 9-inch cake pans, then cut and place parchment rounds in the bottoms and grease the parchment as well.
Chef’s tipIf your parchment is stiff, press it into the pan with a little butter or oil so it lies flat; pressing the greased parchment against the pan helps cakes release without tearing.
In a large bowl, whisk together the all-purpose flour, unsweetened natural cocoa powder, granulated sugar, baking soda, baking powder, 1 teaspoon salt, and the espresso powder if using until evenly combined.
Chef’s tipIf your cocoa tends to clump, sift it with the flour before mixing to ensure a smooth batter.
In a separate bowl or the bowl of a mixer, combine the vegetable oil, eggs, and 2 teaspoons pure vanilla extract; beat on medium-high just until blended. Add the buttermilk and mix until incorporated.
Chef’s tipRoom-temperature eggs and buttermilk blend more uniformly and help the batter achieve the proper emulsion.
Add the dry ingredients to the wet mixture, then pour in the hot coffee or hot water and stir or beat on low speed until the batter is completely uniform; the finished batter will be thin.
Chef’s tipStir just until combined; overmixing can tighten the crumb. The thin consistency is expected and produces a moist cake.
Divide the batter equally between the prepared pans and smooth the tops. Bake in the preheated oven for 23–26 minutes, or until a toothpick inserted near the center comes out clean.
Chef’s tipBegin checking at 23 minutes; if the toothpick has a few moist crumbs it's done—cakes made with high cocoa content often appear slightly soft while still fully baked.
Set the pans on a cooling rack and let the cakes cool in the pans for 1 hour. Run a knife around the edge to loosen, invert to remove from the pans, peel off the parchment rounds, and transfer the layers to a wire rack. Allow the cake layers to cool completely to room temperature (about 1 hour on the rack or until no longer warm to the touch) before leveling and frosting.
Chef’s tipIf a layer still clings after an hour in the pan, give it an additional 10–15 minutes in the pan; unmolding too soon can cause breakage.
For the frosting, beat the unsalted butter on medium speed with a paddle attachment until creamy, about 2 minutes. Add the confectioners’ sugar, unsweetened cocoa powder (3/4 cup), 3 Tablespoons heavy cream, 1 teaspoon pure vanilla extract, and 1/4 teaspoon salt; beat on low for 30 seconds, then increase to high and beat 1 full minute. Adjust by adding up to 1/4 cup more confectioners’ sugar or cocoa powder if the frosting is too thin, or 1–2 more Tablespoons heavy cream if it is too thick. Taste and add another pinch of salt if desired.
Chef’s tipStart with the lower cream amount and scrape the bowl between additions; properly softened butter gives a fluffy texture without needing excessive whipping.
If the cooled cake tops are domed, level them with a large serrated knife so the layers sit flat. Place one layer on your serving plate, spread an even layer of frosting across the top, set the second layer in place, then frost the top and sides. Finish with the optional semi-sweet chocolate chips if desired.
Chef’s tipChill the layers for 10–20 minutes if they are very warm before leveling or frosting—cooler layers crumb less and are easier to smooth.
Refrigerate the uncovered, frosted cake for at least 30–60 minutes to let the frosting set before slicing.
Chef’s tipChilling briefly firms the frosting for cleaner slices; if you prefer softer frosting, allow the cake to sit at room temperature for a short while before serving.
After that initial chill you may serve the cake or keep it chilled for a few more hours; it can be served chilled or at room temperature.
Store leftover cake tightly covered in the refrigerator for up to 5 days; use a cake carrier or wrap the cake to protect it from absorbing other odors.
Chef’s tipIf transporting, place the cake in a carrier or on a sturdy board and keep refrigerated until just before departure to maintain structure.
This is a two-layer chocolate cake that balances deep cocoa flavor with tender, moist crumb. The batter blends cocoa, hot coffee, and buttermilk to produce an intensely chocolatey base that remains light because of the oil and eggs, while the buttercream combines confectioners’ sugar and extra cocoa for a smooth, spreadable frosting. Expect tender layers with a satin-textured frosting and the option to finish with a scatter of chocolate chips. The recipe’s straightforward steps and forgiving frosting make it convenient for weekend baking or preparing a day ahead; chilling briefly sets the cake for cleaner slices. Yielding about 13 servings, it’s suitable for gatherings where you want an elegant, crowd-pleasing chocolate dessert without fussy techniques.
