Step 1: Prepare the Vanilla Sponge Cake
Begin by preheating your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper. In a medium bowl, whisk together the flour, baking powder, and salt, then set aside.
In a large mixing bowl, cream the softened butter and sugar until light and fluffy. This process helps incorporate air, resulting in a tender cake crumb. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla bean seeds or vanilla extract.
Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix gently until just combined, being careful not to overmix. Divide the batter evenly between the prepared pans and smooth the tops.
Bake for 25–30 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
Step 2: Make the Custard Filling
In a saucepan, heat the heavy cream and milk over medium heat until it begins to steam but does not boil. If using a vanilla bean, add it to the cream mixture while heating.
In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until smooth and pale. Slowly pour the warm cream mixture into the egg mixture, whisking constantly to prevent curdling.
Return the mixture to the saucepan and cook over medium-low heat, stirring continuously, until the custard thickens. Remove from heat and strain if necessary for a smoother texture. Let the custard cool completely, covering it with plastic wrap pressed directly onto the surface to prevent a skin from forming.
Step 3: Assemble the Cake
Once the cake layers and custard are fully cooled, place one sponge layer on a serving plate. Spread an even layer of custard on top. Carefully place the second cake layer over the custard, pressing gently to secure.
Refrigerate the assembled cake for at least 2 hours. This step helps the custard set and makes the cake easier to finish.
Step 4: Caramelize the Sugar Topping
Just before serving, sprinkle an even layer of sugar over the top of the cake. Using a kitchen torch, caramelize the sugar until it melts and turns a deep amber color. Allow the sugar to harden for a few minutes before slicing.
Serving and Storage:
This Vanilla Bean Crème Brûlée Cake is best served slightly chilled with a freshly caramelized sugar topping. Use a sharp knife to slice through the hardened sugar crust, wiping the blade clean between cuts for neat slices.
If you plan to store the cake, keep it refrigerated in an airtight container for up to three days. For the best texture and flavor, caramelize the sugar topping just before serving rather than in advance. Leftover cake slices should be covered to prevent the custard from absorbing refrigerator odors.
Tips:
- Use room-temperature ingredients for the sponge cake to ensure even mixing.
- Superfine sugar works best for the caramelized topping as it melts more evenly.
- Chilling the cake before adding the sugar topping helps maintain clean layers.
- If you do not have a kitchen torch, you can caramelize the sugar under a broiler, but watch closely to prevent burning.
- For added flavor, consider brushing the cake layers lightly with vanilla syrup before assembling.

FAQ:
Can I make this cake ahead of time?
Yes, the cake layers and custard can be prepared a day in advance. Assemble the cake and refrigerate it, then caramelize the sugar topping just before serving.
Do I need a vanilla bean?
While a vanilla bean provides a deeper flavor and visual appeal, high-quality vanilla extract is an excellent alternative.
What if my custard is too thin?
If the custard does not thicken, return it to low heat and continue stirring. Make sure it reaches a gentle simmer to activate the cornstarch.
Can I freeze this cake?
Freezing is not recommended due to the custard filling, which may separate when thawed.
How do I get a perfect sugar crust?
Apply the sugar in a thin, even layer and move the torch steadily to avoid burning one spot. Allow the sugar to cool and harden before slicing.
