Step-by-Step Instructions

1. Prepare the Cake Batter

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.
2. In a large mixing bowl, sift together the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder. Whisk to combine evenly.
3. Add the vegetable oil, eggs, and vanilla extract to the dry ingredients. Mix on medium speed using a hand or stand mixer until combined.
4. Slowly add the buttermilk, mixing on low speed. Once incorporated, pour in the hot coffee and continue mixing until the batter is smooth. The batter will be thin, but that’s perfect for a moist cake.

2. Bake the Cake

1. Divide the batter evenly between the prepared pans.
2. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
3. Remove the cakes from the oven and allow them to cool in the pans for 10 minutes. Then, transfer them to a wire rack to cool completely.

3. Make the Chocolate Buttercream

1. In a large bowl, beat the softened butter on medium speed until creamy and fluffy (about 2 minutes).
2. Add the confectioners’ sugar and cocoa powder gradually, beating on low speed to prevent a sugar cloud.
3. Increase to medium speed and add the heavy cream, vanilla extract, and salt. Continue beating until the frosting is smooth and spreadable. Adjust the consistency with additional cream if needed.

4. Assemble the Cake

1. Level the tops of the cake layers with a serrated knife if necessary.
2. Place one cake layer on a serving plate or cake stand. Spread a generous layer of buttercream on top.
3. Add the second cake layer and frost the top and sides with the remaining buttercream.
4. Optional: Decorate with semi-sweet chocolate chips or other toppings of your choice.
