Ingredients
For the Cake:
-
1 cup (120 g) all-purpose flour
-
7/8 cup (175 g) granulated sugar
-
6 tablespoons (44 g) dark cocoa powder
-
1 teaspoon baking soda
-
½ teaspoon baking powder
-
½ teaspoon salt
-
½ cup (120 g) buttermilk, room temperature
-
½ cup (118 g) hot water or brewed coffee
-
¼ cup (55 g) vegetable oil
-
2 large eggs, room temperature
-
½ teaspoon pure vanilla extract
For the Ganache:
-
½ cup (115.5 g) heavy whipping cream
-
5 oz dark chocolate chips (or chopped chocolate bar)
Instructions
-
Preheat the oven to 325°F (163°C). Spray an 8-inch round cake pan with non-stick spray, line with parchment paper, and spray again. Set aside.
-
In a large bowl or the bowl of a stand mixer, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
-
In a separate bowl, whisk together buttermilk, hot water (or coffee), oil, eggs, and vanilla extract.
-
With the mixer on low speed, slowly pour the wet mixture into the dry ingredients. Scrape down the sides and bottom of the bowl to fully combine.
-
Pour the batter into the prepared pan. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs.
-
Let the cake cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely (or enjoy it slightly warm).
-
To make the ganache: heat heavy cream in the microwave for 1 minute, then pour over the chocolate chips. Stir until smooth and glossy.
-
Let the ganache cool slightly before pouring over the cake. It will thicken as it cools. Slice, serve, and enjoy!
Notes
- No buttermilk? No problem. Just mix ½ cup milk with 1½ tsp lemon juice or vinegar and let it sit for 5 minutes. Instant buttermilk!
- Coffee deepens the chocolate flavor without making it taste like coffee. Highly recommended!
- This cake keeps well for a few days at room temp and even better in the fridge. Just bring to room temp or give it a quick zap before serving.
