- Preheat oven to 350°F (175°C).
- Grease two 8-inch round cake pans. Line bottoms with parchment, then grease the parchment.
- Lightly dust with cocoa powder (instead of flour) to avoid white streaks on the cake.
2) Mix the dry ingredients
- In a large bowl, whisk flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt.
- Break up any cocoa lumps with your whisk so the batter bakes evenly.
3) Add the wet ingredients (except hot coffee)
- Add eggs, oil, buttermilk, and vanilla to the dry ingredients.
- Mix just until combined. The batter will look thick at this stage.
4) Bloom the cocoa with hot coffee
- Slowly pour in the hot coffee while mixing on low (or whisking). The batter will become thin—this is normal.
- Optional: fold in mini chocolate chips.
- Let batter sit 2 minutes to let bubbles settle for a smoother crumb.
5) Bake
- Divide batter evenly between prepared pans.
- Bake 28–35 minutes, or until a toothpick comes out with a few moist crumbs (not wet batter).
- Cool in pans 10–15 minutes, then turn out onto a rack to cool completely.
6) Make the fudge frosting
- Beat softened butter until creamy (about 1–2 minutes).
- Add powdered sugar, cocoa powder, salt, vanilla, and heavy cream. Beat on low, then increase speed until fluffy.
- If using melted chocolate, pour it in and beat until smooth and glossy.
- Adjust texture: add a splash of cream to loosen, or a bit more powdered sugar to thicken.
7) Assemble the cake
- If needed, level cake layers with a serrated knife for a flat stack.
- Spread frosting on the first layer, add the second layer, then frost the top and sides.
- Optional: swirl frosting decoratively and finish with shavings, berries, or a tiny pinch of flaky salt.
Serving and Storage:
Serve this cake slightly cool or at room temperature. For the cleanest slices, chill the frosted cake for 20–30 minutes,
then slice with a warm knife (run it under hot water and wipe dry between cuts).
- Room temperature: 1–2 days (covered, cool room).
- Refrigerator: up to 5 days in an airtight container. Bring to room temp for best texture.
- Freeze (layers): wrap unfrosted layers tightly and freeze up to 2 months.
- Freeze (slices): wrap slices individually for grab-and-go dessert later.
Tips:
- Hot coffee = deeper chocolate: It doesn’t make the cake taste like coffee—it intensifies cocoa flavor.
- Buttermilk substitute: Mix 1 cup milk + 1 tbsp lemon juice or vinegar. Let sit 5 minutes.
- Don’t overmix: Mix just until combined to keep the crumb tender.
- Don’t overbake: Pull the cake when the toothpick has a few moist crumbs.
- Use oil for moisture: Oil stays liquid at room temperature, keeping cake softer longer than butter-only cakes.
- Chocolate chips trick: Mini chips distribute better and create fudgy pockets without sinking as much.
Variations:
- Sheet cake: Bake in a 9×13-inch pan for 30–40 minutes. Frost right in the pan—easy party style.
- Cupcakes: Fill liners 2/3 full and bake 18–22 minutes. Makes about 18–22 cupcakes.
- Mocha lovers: Add 1–2 tsp espresso powder to the batter and a splash to the frosting.
- Chocolate-peanut butter: Fill layers with peanut butter frosting or add peanut butter cups on top.
- Black forest vibe: Add cherry filling between layers and garnish with cherries + chocolate curls.
- Dairy-free: Use dairy-free milk “buttermilk” (plant milk + lemon) and dairy-free butter for frosting.
- Gluten-free: Use a 1:1 gluten-free flour blend designed for baking (texture may be slightly different).
Tips:
- Make-ahead win: Bake layers a day early, wrap well, and frost the next day for stress-free serving.
- Frosting consistency: Softer frosting spreads more easily; stiffer frosting holds sharp swirls.
- Extra moist finish: Brush layers with a simple syrup (equal parts sugar + water, warmed) before frosting.
- Sharper chocolate flavor: Add a pinch more salt to the batter (salt boosts cocoa intensity).
- Clean edges: Do a thin “crumb coat,” chill 15 minutes, then apply final frosting.

FAQ:
Does the cake taste like coffee?
No. Coffee mainly boosts the chocolate flavor. If you prefer, use hot water instead.
Can I use Dutch-process cocoa or natural cocoa?
Yes. Both work. Dutch-process tends to taste smoother and darker; natural cocoa can taste sharper and more classic.
Why is the batter so thin?
That’s normal for this style of ultra-moist chocolate cake. Thin batter bakes into a soft crumb and helps prevent dryness.
How do I keep chocolate cake moist for days?
Don’t overbake, store airtight, and keep it frosted (frosting acts like a moisture seal). Refrigerate and bring to room
temperature before serving for the best texture.
Can I make this cake without eggs?
You can try egg substitutes (like flax eggs), but the texture may change. For best results, use a tested egg-free chocolate
cake recipe if you need a guaranteed outcome.
