Ingredients

Chocolate Moist Cake

250 g (1¼ cups) brown sugar
160 ml (⅔ cup) buttermilk
160 ml (⅔ cup) vegetable oil
120 g (½ cup) plain yogurt
2 large eggs
1 tsp vanilla extract
280 g (2⅓ cups) all-purpose flour
1 tsp baking powder
2 tsp baking soda
½ tsp salt

Cocoa–Coffee Mix

250 ml (1 cup) hot water
1 tbsp instant coffee
50 g (½ cup) cocoa powder

Dark Chocolate Crèmeux

200 g dark chocolate (chopped)
120 ml (½ cup) milk
120 ml (½ cup) whipping cream
2 whole eggs + 1 egg yolk
25 g (about 2 tbsp) sugar

Chocolate Cream Cheese Filling

250 g cream cheese (softened)
1 tsp vanilla extract
15 g (2 tbsp) cocoa powder
30 g (¼ cup) powdered sugar
120 ml (½ cup) cold whipping cream

Instructions

Step 1: Make the dark chocolate crèmeux base

In a saucepan, combine 2 whole eggs + 1 yolk, 120 ml milk, 120 ml whipping cream, and 25 g sugar. Cook on low heat, stirring frequently, until it reaches a gentle simmer (do not boil).

Step 2: Melt into dark chocolate and chill

Pour the hot mixture over 200 g dark chocolate. Let sit for 5 minutes, then stir until silky smooth. Press cling wrap directly onto the surface and refrigerate for at least 2 hours.

Step 3: Mix the cream cheese base

In a mixing bowl, combine 250 g cream cheese, 1 tsp vanilla, 15 g cocoa powder, and 30 g powdered sugar. Mix until smooth.

Step 4: Add cream, then blend in the cold crèmeux

While mixing, pour in 120 ml cold whipping cream and beat until smooth and creamy. Add the chilled chocolate crèmeux and mix again until fully combined. Cover with cling wrap (touching the surface) and refrigerate for at least 1 hour.

Step 5: Preheat oven and prepare pan

Preheat oven to 160°C (320°F). Line a 13″ × 10″ tray (or 13″ × 9″ pan) with parchment.

Step 6: Make the cake batter (wet ingredients)

In a large bowl, whisk together 250 g brown sugar, 160 ml buttermilk, 160 ml vegetable oil, and 120 g plain yogurt. Add 2 eggs and 1 tsp vanilla, whisk until well combined.

Step 7: Sift in dry ingredients

Sift in 280 g flour, 1 tsp baking powder, 2 tsp baking soda, and ½ tsp salt. Mix just until incorporated.

Step 8: Make the cocoa–coffee mix

In a jug, stir together 250 ml hot water, 1 tbsp instant coffee, and 50 g cocoa powder until smooth.

Step 9: Finish batter and bake

Pour the cocoa–coffee mixture into the batter and whisk until smooth. Pour into the prepared pan and bake for 30–35 minutes.

Step 10: Cool and cut

Cool the cake completely. Cut into 4″ × 8″ pieces to fit a loaf pan. Slice each piece horizontally to create more layers, if desired.

Step 11: Assemble in loaf pan

Line a 4″ × 8″ loaf pan with parchment. Add a cake layer, pipe/spread the chocolate filling, then repeat layers as you like (cake → filling → cake → filling).

Step 12: Chill before serving

Refrigerate for at least 4–5 hours or overnight before slicing and serving.

Tips & Notes

Keep the crèmeux on low heat: boiling can scramble the eggs and make it grainy.
Cling wrap on the surface prevents a skin from forming.
Don’t overmix flour: it keeps the cake tender and moist.
For sharp layers, use a warm knife, wipe between slices, and serve chilled.

Variations

Milk chocolate crèmeux: swap dark chocolate for milk chocolate for a sweeter finish.
Extra mocha: increase instant coffee to 1½ tbsp.
Add texture: sprinkle crushed cookies or toasted nuts between layers.
Mini portions: assemble in small cups or mini loaf pans for individual servings.

Storage & Make-Ahead

Fridge: Store covered for 4–5 days.
Make-ahead: Best made the day before for the cleanest slices.
Freezer: Freeze slices up to 1 month. Thaw overnight in the fridge.

Serving Suggestions

Serve cold for perfect layers, or let sit 10 minutes at room temperature for a softer bite.
Top with cocoa powder, chocolate shavings, or a drizzle of melted chocolate.
Pair with espresso, cappuccino, or cold milk.

Frequently Asked Questions

Can I make this recipe without coffee?
Yes. The coffee enhances chocolate flavor but doesn’t make it taste like coffee. You can replace the instant coffee with extra hot water (same amount).

How do I know the cake is done?
A toothpick should come out with a few moist crumbs—not wet batter. Avoid overbaking to keep it moist.

Why does the cake need to chill so long after assembly?
Chilling helps the filling set firmly for clean slices and improves the overall texture.

Can I make the crèmeux and filling ahead of time?
Yes. The crèmeux can be made 1–2 days ahead, and the filling can be made 1 day ahead. Keep both covered with cling wrap touching the surface.

Can I freeze the assembled cake?
Yes. Freeze slices tightly wrapped for up to 1 month. Thaw overnight in the fridge for best results.
