Custard Flan Cake 💜 Recipe
Introduction
This Custard Flan Cake is a delightful treat that combines creamy flan, soft sponge cake, and rich caramel syrup. With a smooth texture and balanced sweetness, it’s perfect for special occasions or a comforting dessert any day.

Ingredients
- Caramel Syrup:
- 3/4 cup sugar
- 1/4 cup water
- Flan:
- 4 whole eggs
- 1 can condensed milk
- 1 1/2 cups fresh milk
- 1 tsp vanilla extract
- Sponge Cake:
- 4 egg yolks
- 1/4 cup sugar
- 1/4 cup oil
- 1/4 cup milk
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- 1 tsp baking powder
- 1/2 tsp salt
- Meringue:
- 4 egg whites
- 1 tsp lemon juice
- 1/4 cup sugar
Instructions
- Step 1: Make the caramel syrup by combining sugar and water in a saucepan over medium heat. Stir until the sugar dissolves, then let it simmer without stirring until it turns a golden amber color.
- Step 2: Pour the caramel syrup into an 8-inch cake pan and swirl to coat the bottom evenly. Set aside to harden.
- Step 3: Whisk together the flan ingredients: eggs, condensed milk, fresh milk, and vanilla extract. Set this mixture aside.
- Step 4: For the sponge cake, beat the egg yolks, sugar, oil, milk, and vanilla extract until combined. In a separate bowl, sift together the flour, baking powder, and salt, then gently fold into the wet ingredients using a spatula. Set aside.
- Step 5: Beat the egg whites with lemon juice until frothy. Gradually add the sugar while beating until stiff peaks form, creating a meringue.
- Step 6: Carefully fold the meringue into the sponge cake batter until just combined.
- Step 7: Pour the flan mixture gently over the caramel syrup in the cake pan.
- Step 8: Spoon the sponge cake and meringue mixture evenly on top of the flan layer.
- Step 9: Cover the cake pan with aluminum foil to prevent condensation. Bake in a steamer or steam on the stovetop for 1 hour and 30 minutes, checking doneness with a toothpick (it should come out clean).
- Step 10: Remove from heat and allow to cool. Refrigerate for several hours or overnight to set properly.
- Step 11: To serve, invert the cake onto a plate so the caramel syrup drizzles over the flan. Slice and enjoy your delicious Custard Flan Cake.
Tips & Variations
- Use fresh eggs for the best texture and flavor in your flan and sponge layers.
- If you don’t have a steamer, you can bake the cake in a water bath (bain-marie) in the oven at 325°F (160°C) for the same amount of time.
- For a hint of citrus, add a teaspoon of orange zest to the sponge cake batter.
Storage
Store the Custard Flan Cake covered in the refrigerator for up to 3 days. Reheat by letting it sit at room temperature for about 15 minutes before serving, or enjoy it chilled for a refreshing dessert.

FAQs
Can I use evaporated milk instead of fresh milk?
Yes, evaporated milk can be used for a richer flan, but reduce the sweetness slightly since it’s more concentrated than fresh milk.
Is steaming necessary, or can I bake it in the oven?
Steaming is traditional and gives a moist texture, but you can bake the flan cake in a water bath in the oven at 325°F (160°C) for about 1 hour and 30 minutes with similar results.

Ingredients
Caramel Syrup
- 3/4 cup sugar
- 1/4 cup water
Flan
- 4 whole eggs
- 1 can condensed milk (approx. 395g)
- 1 1/2 cups fresh milk
- 1 tsp vanilla extract
Sponge Cake
- 4 egg yolks
- 1/4 cup sugar
- 1/4 cup oil
- 1/4 cup milk
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- 1 tsp baking powder
- 1/2 tsp salt
Meringue
- 4 egg whites
- 1 tsp lemon juice
- 1/4 cup sugar
Instructions
- Prepare Caramel Syrup: In a small saucepan, combine 3/4 cup sugar and 1/4 cup water over medium heat. Stir until the sugar dissolves, then stop stirring and let it simmer until it turns a deep amber color. Immediately pour the caramel syrup into an 8-inch cake pan and swirl to coat the bottom evenly.
- Make Flan Mixture: In a mixing bowl, whisk together 4 whole eggs, 1 can condensed milk, 1 1/2 cups fresh milk, and 1 teaspoon vanilla extract until fully combined and smooth. Set aside.
- Prepare Sponge Cake Batter: In a separate bowl, beat 4 egg yolks with 1/4 cup sugar until the mixture is light and creamy. Add 1/4 cup oil, 1/4 cup milk, and 1 teaspoon vanilla extract and mix well. Sift in 1 cup all-purpose flour, 1 teaspoon baking powder, and 1/2 teaspoon salt. Gently fold the dry ingredients into the wet ingredients using a spatula until just combined. Set aside.
- Make Meringue: In a clean, dry bowl, beat 4 egg whites with 1 teaspoon lemon juice until frothy. Gradually add 1/4 cup sugar while continuing to beat until stiff peaks form. Fold the meringue gently into the sponge cake batter until evenly incorporated.
- Assemble the Cake: Pour the flan mixture carefully over the caramel syrup in the cake pan. Then, gently spoon the sponge cake and meringue mixture over the flan mixture, spreading evenly without mixing.
- Steam Bake the Cake: Cover the cake pan tightly with aluminum foil. Place the pan in a steamer or large pot with boiling water and steam for 1 hour and 30 minutes. Check doneness by inserting a toothpick into the sponge layer – it should come out clean. Remove from steam and allow to cool to room temperature.
- Refrigerate and Serve: Once cooled, refrigerate the cake for several hours or overnight to set fully. To serve, carefully invert the cake onto a serving plate, allowing the caramel to drizzle over the flan layer. Slice and enjoy this luscious custard flan cake.
Notes
- You can also steam the cake using the same method described; steaming ensures a moist and tender texture.
- Use an 8-inch round cake pan for best results.
- Make sure to cover the pan tightly with foil during steaming to prevent water from dripping into the cake.
- Letting the cake chill overnight enhances the flavor and makes slicing easier.
- Check doneness with a toothpick inserted in the sponge layer, not the custard, for accurate results.
