This chocolate custard cake has a crisp chocolate cookie crust, a silky dark chocolate custard filling, and a cloud of whipped cream on top.
The custard is cooked on the stove, poured over the crust, and baked until just set. Allow about 3 hours in total, which includes cooling and chilling, and the cake slices neatly into 8 wedges.

Why This Chocolate Custard Cake Recipe Works
The filling is a real stovetop custard, so it bakes into a dense, creamy texture that sits between a cake and a pudding.
A crushed chocolate cookie crust needs no flour, and it stays crisp beneath the soft filling.
Dark chocolate gives a deep flavor that is not overly sweet, and fresh berries balance the richness.
Ingredients for Chocolate Custard Cake
- 7 ounces chocolate sandwich cookies, crushed into fine crumbs, for the crust
- 4 tablespoons unsalted butter, melted, for the crust
- 3 cups whole milk, for the custard
- 2 teaspoons vanilla extract, for the custard
- 2/3 cup superfine sugar, for the custard
- 7 large egg yolks, about 120 grams, for the custard
- 5 tablespoons cornstarch, for the custard
- 7 ounces dark chocolate, 70 percent cocoa, finely chopped, for the custard
- 1 cup heavy cream, for the whipped topping
- 2 tablespoons powdered sugar, for the whipped topping
- 1 cup fresh raspberries or sliced strawberries, for serving
- 1 tablespoon powdered sugar, for dusting
Cookie crust. Crush the whole cookies, cream filling included, until the crumbs look like wet sand.
Egg yolks. Yolks make the custard rich and silky, and the cornstarch keeps it stable.
Dark chocolate. Use a good bar rather than chips, which contain stabilizers and may not melt as smoothly.
Whole milk. Full fat milk gives the ideal body and flavor.
Fresh berries. Raspberries add a tart note that cuts through the chocolate.
How to Make Chocolate Custard Cake
1. Prepare the pan. Heat the oven to 350 degrees F. Grease an 8 inch springform pan and line the bottom with parchment paper.
2. Make the crust. Mix the cookie crumbs with the melted butter and press firmly into the bottom of the pan. Chill while you make the custard.
3. Start the custard. Whisk the milk, vanilla, sugar, cornstarch, and egg yolks in a saucepan before turning on the heat, so the cornstarch dissolves.
4. Cook until thick. Cook over medium low heat, whisking constantly, for 5 to 7 minutes until the custard thickens, bubbles slowly, and reaches 160 degrees F.
5. Add the chocolate. Take the pan off the heat, add the chopped chocolate, and whisk until smooth. Cool for 10 minutes.
6. Bake. Pour the custard over the crust and bake for 30 to 35 minutes, until the edges are set and the center jiggles slightly.
7. Cool and chill. Cool in the pan for 1 hour, then refrigerate for at least 1 hour before unmolding.
8. Top and serve. Whip the cream with 2 tablespoons powdered sugar, spoon it over the cake, add berries, and dust with powdered sugar.
How to Serve Chocolate Custard Cake
Cut the chilled cake into wedges and serve with extra berries and a pot of coffee. For a dessert board, add a slice of three layer custard cake, a wedge of New York cheesecake, and a few squares of red velvet brownies. A glass of berry kefir smoothie makes a lighter pairing.
How to Store and Reheat Chocolate Custard Cake
Cover the cake and refrigerate it for up to 3 days, and do not leave it at room temperature for more than 2 hours because it contains eggs and milk. Freezing is not recommended, since the custard can turn watery. Serve slices chilled with fresh whipped cream.
Tips and Variations for Chocolate Custard Cake
Whisk constantly. Keep the whisk moving across the bottom and corners of the pan to prevent lumps.
Use a thermometer. Cooking the custard to 160 degrees F makes the eggs safe and the texture smooth.
Chop the chocolate finely. Small pieces melt quickly and evenly in the hot custard.
Do not overbake. The center should still jiggle slightly, since it sets as it cools.
Cool slowly. Let the cake rest in the pan before chilling to prevent cracks.
Release carefully. Run a thin knife around the edge before opening the springform pan.
Swap the toppings. Try sliced strawberries, orange segments, or chopped hazelnuts.
Handle eggs safely. Keep the cake cold and follow egg guidelines like those in this Montana State University Extension egg safety sheet.
