Ingredients You’ll Need
One of the reasons I adore this recipe is how it takes pantry staples and transforms them into something truly spectacular. Each ingredient contributes its own magic—richness, depth, or texture—so together, they’re a symphony for your senses.

- Baking powder and baking soda: These give your cake its light, fluffy lift.
- Salt: Just a touch sharpens and balances the sweetness.

How to Make Rich Chocolate custard cake recipe
Step 1: Prepare Your Cake Pans and Oven
Begin by preheating your oven to 180°C (350°F) and greasing two 8-inch cake pans. A quick dusting of flour ensures your cake layers pop out beautifully and with ease, keeping that gorgeous crumb intact.
Step 2: Mix Dry Ingredients
In a large bowl, stir together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. This base creates a harmonious blend, setting the stage for a cake with both structure and deep flavor.
Step 3: Add Wet Ingredients
Pour in the milk, vegetable oil, eggs, and vanilla extract. Mix until the batter is smooth and glossy—no lumps allowed! The combination of milk and oil guarantees an incredibly moist cake.
Step 4: Incorporate Hot Water or Coffee
Gradually stream in the hot water or coffee, whisking gently. The batter will thin out, which is exactly what you want for an ultra-tender cake crumb. If you use coffee, you’ll intensify those chocolate undertones in the Rich Chocolate custard cake recipe.
Step 5: Bake the Cake Layers
Divide the batter evenly between your prepared pans and bake for 30 to 35 minutes. You’re looking for cakes that have risen and spring back when gently touched. To check doneness, a toothpick inserted should come out clean or with just a few moist crumbs.
Step 6: Cool Completely
Let the cakes cool in their pans for about 10 minutes, then turn them out onto wire racks. Allow them to cool fully, which prevents the custard from melting when you assemble the Rich Chocolate custard cake recipe.
Step 7: Make the Chocolate Custard Filling
For the custard, start by whisking the egg yolks, sugar, cornstarch, and cocoa powder in a saucepan until completely smooth. Gradually add milk, whisking to blend everything together.
Step 8: Cook the Custard
Set the pan over medium heat, stirring constantly, until the mixture thickens into a glossy, luscious custard. Once thickened, take it off the heat and stir in the chopped dark chocolate, butter, and vanilla until everything is velvety. Cover with plastic wrap (press it to the surface!) and chill until firmly set.
Step 9: Assemble the Cake
Place one cooled cake layer on your serving plate and spread a generous layer of the chilled chocolate custard over top. Add the second cake layer and cover the top and sides with more custard. For that show-stopping Rich Chocolate custard cake recipe look, gently press chocolate cake crumbs around the base and sides.
Step 10: Chill and Decorate
Pop the completed cake into the fridge for at least 1 hour to set everything perfectly. When ready, crown your masterpiece with dollops of whipped cream or lashings of chocolate ganache and sprinkles of extra cake crumbs if you like.
How to Serve Rich Chocolate custard cake recipe

Garnishes
A cake as luscious as this deserves the royal treatment! Swirls of freshly whipped cream, a glossy drizzle of ganache, and a scattering of chocolate shavings or fresh berries all make lovely finishing touches. The contrast between smooth custard and airy cream is pure delight.
Side Dishes
Rich Chocolate custard cake recipe shines solo, but if you’re going all out, serve each slice alongside a scoop of vanilla ice cream or a handful of juicy raspberries. The fruity tartness and cold creaminess play beautifully against the deeply chocolatey cake.
Creative Ways to Present
For a playful twist, cut the cake into squares and serve as decadent petit fours or layer cubes with whipped cream in parfait glasses for an elegant deconstructed dessert. If you’re feeling extra creative, top with edible flowers or gold leaf for that Instagram-worthy wow-factor.
Make Ahead and Storage
Storing Leftovers
Once assembled, cover any leftover cake tightly with plastic wrap or transfer to an airtight container. It will keep in the refrigerator for up to four days, and honestly, the flavors often get even more intense and dreamy with time!
Freezing
You can freeze the unfilled cake layers for up to three months. Just wrap them well in plastic and foil, and thaw at room temperature before assembly. While the assembled Rich Chocolate custard cake recipe isn’t ideal for freezing due to the custard, individual slices can be frozen and thawed overnight in the fridge for a quick treat.
Reheating
This cake is best served chilled or at room temperature. If you’d like to take the chill off, simply let a slice sit out for 20 minutes before serving—it helps bring out the custard’s silky texture and the cake’s moist crumb.
