Notes and substitutions
- Unsweetened cocoa powder: Dutch-process cocoa powder results in a darker, fudgier cake. I used Hershey's "Special Dark" Cocoa Powder.
- Oil: Use a neutral-flavored oil like canola, avocado, or other vegetable oils. Mild-tasting oils like coconut and olive oil also work great.
- Dark chocolate: Use bars, chips, or wafers with a high cocoa percentage (semisweet or bittersweet).
- Buttermilk: It plays a crucial role in making the cake tender and fluffy. If not available, create a buttermilk substitute or use other cultured dairy products like yogurt or sour cream diluted with water as replacements.
Buttermilk substitute
Step 1: Combine slightly less than a cup of milk and 1 tablespoon vinegar or lemon juice in a cup.
Step 2: Allow it to rest for 5 to 10 minutes until it thickens and curdles, forming a perfect homemade substitute.
How to make this recipe
Prep and organize
- Use a kitchen scale for precise ingredient measurements. If a scale is unavailable, remember to measure the flour accurately. Fluff the flour, then spoon it into a measuring cup without packing it down. Use a flat edge to level off the excess flour for consistency.
- Prepare three 6-inch or two 8-inch round pans. Grease them with oil or butter and line them with parchment paper.
- Bring the eggs to room temperature. You can submerge them in warm tap water until no longer cool to the touch.
- Finely chop the chocolate — the smaller the pieces, the faster they melt.
Make the frosting
Step 1: Heat 1½ cups heavy cream until very hot and combine it with 12 ounces of chocolate and 3 tablespoons butter in a small bowl.
Step 2: Let it sit for about 2 minutes to melt the chocolate, then mix until smooth. Refrigerate until it reaches a medium-thick, spreadable consistency for about an hour.
Make the cake layers
Preheat the oven to 350° F (177° C).
Step 3: Sift 1¾ cups flour, 1¾ cups sugar, 1 teaspoon baking powder, 1 teaspoon baking soda, 1 teaspoon kosher salt (use half for table salt), and ¾ cup cocoa powder into a large bowl.
Step 4: Whisk the dry ingredients together and set them aside.
Step 5: In a medium bowl, combine ¾ cup hot coffee and 3 ounces of chocolate. Let it sit for 2 minutes to melt the chocolate, then mix it until smooth.
Step 6: Add 1 cup buttermilk, 2 eggs, ½ cup oil, and 1 teaspoon vanilla extract. Whisk the wet ingredients until combined.
Step 7: Add wet ingredients to the dry ingredients.
Step 8: Whisk the ingredients until they are just combined, being careful not to overmix.
Step 9: Divide the batter between the pans and tap them gently to eliminate holes.
Step 10: Bake for 25 to 30 minutes—a toothpick inserted should come out almost clean. Cool in the pan for 10 minutes, then transfer to a wire rack or flat surface.
PRO TIP: To cool faster, freeze the cakes in the pan for about 30 minutes. It will also be easier to frost.
Make the shards
Step 11: Melt chocolate in the microwave for 1 to 2 minutes in 30-second intervals. Do not overheat. Mix until smooth.
Step 12: With an offset spatula, thinly spread the melted chocolate on parchment paper, approximately 12” x 16” in size.
Step 13: Place another sheet on top, roll it up, and seal it with tape. Refrigerate for a few minutes until firm.
Step 14: Unroll the sheet when ready to garnish. Gently lift the pieces to decorate the cake.
Assemble the cake
Step 15: Fill the cake layers with a thin layer of frosting (about ½ cup) and spread evenly. Use the rest of the frosting to cover the cake.
Step 16: Decorate the cake with chocolate shards all around. Refrigerate for at least an hour before serving.

Recipe FAQs
Yes! You can experiment with different types of flour as substitutes. I have tried substituting with an equal amount of white whole wheat flour or 50% regular whole wheat flour with no issues.
Feel free to get creative and find the flour that suits your taste and dietary preferences.
Yes. Cold eggs can still produce a tasty cake, but room temperature eggs blend more smoothly with other ingredients. It leads to a better rise and a more even texture in your finished cake.
So, whenever possible, it's a good idea to bring your eggs to room temperature before baking.
Yes. Fill the cupcake liners with about three tablespoons of batter or ⅔ full. You can make 24 standard cupcakes and bake them at 350° F (177° C) for 10 to 12 minutes.
