Prep Time, Cook Time, and Servings

Prep Time: 20 minutes | Cook Time: 30-35 minutes | Total Time: 1 hour (plus cooling) | Servings: 12 slices

Ingredients

For the Chocolate Cake:

• 2 3/4 cups (330g) all-purpose flour
• 2 1/2 cups + 2 tbsp (525g) granulated sugar
• 1 cup + 2 tbsp (108g) unsweetened Dutch-process cocoa powder
• 3 tsp (15g) baking soda
• 1 1/2 tsp (6g) baking powder
• 1 1/2 tsp (9g) salt
• 1 1/2 cups (360ml) buttermilk, at room temperature (or substitute: 1 1/2 tbsp (22ml) apple cider vinegar or lemon juice mixed with 1 1/2 cups (360ml) milk of choice)
• 3/4 cup (180ml) avocado oil (or neutral oil of choice)
• 3 eggs, at room temperature
• 1 tbsp (12g) vanilla bean paste or extract
• 1 1/2 cups (360ml) hot, freshly brewed coffee or espresso

For the Chocolate Frosting:

• 1 1/2 cups (339g) salted butter, at room temperature
• 8oz (1 block; 250g) cream cheese, at room temperature
• 1 1/2 cups (144g) unsweetened Dutch-process cocoa powder
• 5 cups (600g) powdered sugar
• 1/4 cup (60ml) heavy cream, at room temperature
• 1 tbsp (12g) vanilla bean paste or extract
• 1/4 tsp (1g) salt

Step-by-Step Instructions

1. Preheat the Oven and Prepare the Pans

Preheat the oven to 350°F (175°C). Grease three 9-inch round cake pans with butter, then dust with flour. Line the bottoms with parchment paper rounds to prevent sticking. Set aside.

2. Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Ensure everything is evenly combined for a uniform cake texture.

3. Combine the Wet Ingredients

In another large bowl, whisk the buttermilk, avocado oil, eggs, and vanilla until smooth. The mixture should be well blended before adding the dry ingredients.

4. Form the Cake Batter

Gradually add the dry ingredients to the wet mixture, whisking until just combined. The batter should be thick—similar to brownie batter. Then, pour in the hot coffee and stir quickly until fully incorporated. The batter will thin significantly.

5. Divide and Bake

Divide the batter evenly among the three prepared pans (roughly 664g per pan for precision). Bake for 30-35 minutes or until a toothpick inserted in the center comes out with just a few moist crumbs. Let the cakes cool in the pans for 15-20 minutes before transferring to a wire rack to cool completely.

6. Make the Chocolate Frosting

Meanwhile, beat the butter and cream cheese in a large mixing bowl until smooth. Add the cocoa powder, powdered sugar, heavy cream, vanilla, and salt. Whip until light and fluffy, scraping the bowl as needed.

7. Assemble the Cake

Once the layers are cooled, place one on a cake stand. Spread a generous layer of frosting, then top with the next layer. Repeat, then frost the top and sides. Use a cake scraper for smooth edges or a rustic look.

Pro Tips for Perfect Results

• Room Temperature Ingredients: Cold ingredients don’t blend as smoothly, so ensure your eggs, buttermilk, and butter are at room temperature.
• Sift the Cocoa Powder: Eliminate lumps in the cake and frosting by sifting the cocoa powder before use.
• Weigh the Batter: For uniform layers, weigh the batter when dividing it into the cake pans.
• Don’t Overmix: Overworking the batter can lead to a dense cake—mix just until combined.
• Hot Coffee Enhance Flavor: Even if you don’t love coffee, it deepens the chocolate taste without overpowering it.

Variations & Substitutions

• Gluten-Free: Swap all-purpose flour for a 1:1 gluten-free blend.
• Dairy-Free: Use plant-based milk and vegan butter for the cake and frosting.
• Healthier Option: Replace half the oil with unsweetened applesauce for reduced fat.
• Mocha Frosting: Add 1 tsp of instant espresso powder to the frosting for a mocha kick.

Storage & Reheating

Store leftover cake in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days. For longer storage, wrap individual slices in plastic wrap and freeze for up to 3 months. Thaw in the fridge before serving.

Frequently Asked Questions

Can I skip the coffee in the recipe?

Yes! Hot water can replace coffee, but coffee enhances the chocolate flavor without making it taste like coffee.

What if I don’t have Dutch-process cocoa?

Regular unsweetened cocoa works, but Dutch-process has a smoother flavor. If using regular, add 1/4 tsp baking powder to balance acidity.

Can I use a different frosting?

Absolutely! Swiss meringue buttercream or ganache also pair beautifully with this cake.

Why is my cake dense?

Overmixing or expired leavening agents can cause density. Always check baking soda/powder freshness.
