This German Fruit Flan is a bright and refreshing dessert that always disappears fast at gatherings. The light sponge cake base is blanketed in homemade vanilla custard and jeweled with a crown of berries. It is perfect with afternoon coffee or to finish a special meal. I love how the contrasting textures come together with every forkful.
I made this for my friend’s birthday brunch, and everyone asked for seconds before I could even get a picture. The combo of soft cake, creamy custard, and fruit glaze is absolute bliss.
Ingredients
- Eggs: fresh large eggs give the sponge cake lift and fluffiness choose eggs with bright yolks for the best color
- Sugar: regular granulated sugar sweetens both cake and custard make sure it is fine so it blends evenly
- All purpose flour: provides structure to the sponge cake sift if it seems clumpy for a smoother batter
- Cornstarch: in the cake it keeps the crumb soft and in the custard it thickens without making it gloopy buy a fresh box for best thickening
- Baking powder: crucial for a light airy base check the date as old baking powder will not lift
- Milk: whole milk gives a rich custard if using low fat the custard will be less velvety
- Egg yolks: only the yolks go in the custard for a silky texture save the whites for another recipe
- Vanilla extract: rounds out the custard flavor use real vanilla for a noticeable upgrade
- Strawberries blueberries raspberries: pick ripe berries at their peak for best flavor and color taste a berry before topping
- Water: to create a glossy glaze and set the fruit in place always use clean fresh water
- Tips: choose firm but fragrant fruit to avoid sogginess in the final tart
Step by Step Instructions
- Prepare the Sponge Cake:
- Preheat your oven to moderate temperature and grease a nine inch flan pan. Dust with flour to ensure easy release. In a large mixing bowl beat eggs with sugar using a handheld mixer or whisk until pale and fluffy. Gently fold in flour cornstarch and baking powder using a rubber spatula until just combined. Do not overmix or the cake may turn tough. Pour batter into the pan and smooth the top. Bake for about twelve to fifteen minutes until golden and just springy. Remove and let cool in the pan before turning out onto a rack
- Make the Vanilla Custard:
- While the cake cools heat milk in a small saucepan over gentle heat just until it is steaming. In a separate bowl whisk egg yolks sugar and cornstarch to blend smoothly with no lumps. While whisking slowly pour in the warm milk to temper the eggs so they do not scramble. Return the mixture to the saucepan and cook on gentle heat stirring constantly with a wooden spoon until the custard thickens enough to coat the spoon. Take off the heat and stir in vanilla. Allow to cool to room temperature. If there are lumps strain through a fine sieve
- Assemble the Flan:
- Place the cooled sponge cake on a serving platter. Pour or spoon the custard evenly over the cake using a spatula to get to the edges. Let the custard cool a bit before adding fruit so it will not melt. Arrange strawberries blueberries and raspberries in an attractive circular pattern over the custard pressing gently so they adhere
- Glaze the Fruit:
- In a clean saucepan combine sugar and cornstarch. Whisk in water until dissolved. Heat over medium until the mixture turns clear and thickens to a syrup. Remove from heat and cool slightly. Using a pastry brush dab the glaze gently over the fruit to create shine and help everything set. Chill the whole flan in the refrigerator for at least one hour so the layers meld and set before serving

Strawberries are my favorite not just for their juicy burst but because my grandmother always added extra for me as a child The taste and scent bring back happy memories of summer visits to her garden
Storage Tips
Store the finished flan covered in the refrigerator. Do not freeze as the custard texture may suffer and fruit will lose its shine. If you have to make it ahead keep sponge base and custard separate until a few hours before serving and assemble fresh to maintain texture.
Ingredient Substitutions
For a gluten free cake substitute the flour with a trusted gluten free blend but check the absorbency as blend textures can vary. If out of fresh berries use thawed frozen ones but dry them well on towels to avoid extra moisture. Almond extract can be swapped in for vanilla to change the flavor profile slightly.
Serving Suggestions
This flan is lovely on its own but a dollop of lightly whipped cream on the side adds a luxurious finishing touch. For a colorful brunch table serve slices with a dusting of powdered sugar and a sprig of fresh mint. Pair with tea or strong coffee for a classic European café vibe.
