A light, silky-smooth treat that’s perfectly sweet and warmly infused with vanilla. Trust me, this recipe is as easy as it is delicious—no need to be intimidated!

This recipe for this vanilla custard flan is the delightful cousin of the crème brûlée, but with a simpler twist. It uses whole eggs - no waste or wondering what to do with leftover egg whites - and skips the heavy cream for a lighter, yet still creamy, texture. It is staple in our home, and one of the first classic desserts I learned to make when I was little.

🥣 Ingredients

To make the Vanilla Custard , you’ll need just a few simple ingredients, but each one plays a key role in achieving that perfect creamy texture and rich flavour:

Eggs: Opt for fresh, large eggs - they provide the structure and creaminess for the flan.
Milk: 2% milk works well but if you prefer a richer texture, go for the whole milk.
Sugar: Regular granulated sugar sweetens the custard just right without overpowering the delicate vanilla flavor.
Vanilla: Use pure vanilla extract or, for an even deeper flavour, scrape the seeds from a vanilla bean.

labelled ingredients: vanilla extract, sugar, eggs, milk.

Variations

While the classic vanilla flavour is timeless, you can easily customize your custard with other extracts or additions:

Almond Flan: Substitute the vanilla extract with almond extract for a nutty twist.
Spiced Flan: A pinch of cinnamon or nutmeg can add warmth and complexity to the custard and make it taste like Fall.
Lavender Flan: For a unique floral flavour, infuse the milk with dried lavender flowers before mixing it into the custard.

📖 Instructions

First, preheat the oven to 375°F.

Next, beat the eggs with the sugar until well combined (picture 1). Add in the vanilla extract (picture 2).

2 cooking steps: on the left a bowl with eggs and sugar and on the right a yellow mixture with a brown liquid with a whisk.

Then, pour in the, previously warmed, milk and whisk (picture 3 and 4).

2 steps of baking: on the left, milk being poured in a bowl with a yellow mixture and on the right a batter with a whisk in the bowl.

Lastly, place ramekin on a baking sheet and pour in the mixture (picture 5).

Prepare the water bath: Place the filled ramekins in a large, deep baking dish. Pour hot water into the baking dish until it reaches halfway up the sides of the ramekins.

This is called a bain-marie or water bath, which ensures gentle, even cooking and prevents the custard from curdling or cracking.

Bake for 30-35 minutes, or until the custard is set and lightly golden on top. The center should still have a slight jiggle when you shake the ramekin gently. You can also put a knife in and if it comes out clean, it is ready.

Cool and serve: Remove the ramekins from the water bath and allow the custard to cool down to room temperature. Garnish with fresh fruits if desired, and serve.

💭 Recipe FAQs

How long can I store the custard flan?

The custard can be stored in the fridge for up to 3 days. Cover the ramekins with plastic wrap or place them in an airtight container to prevent them from absorbing any other odors in the fridge.

Can I make the custard flan ahead of time?

Yes! This custard flan is a great make-ahead dessert. You can prepare and bake it the day before, then refrigerate until ready to serve. Just allow it to come to room temperature before serving or serve it chilled directly from the fridge.

Why does my custard look spongy and liquidy?

If your custard turns out spongy with a liquidy texture, it’s likely overcooked. This can happen if the oven is too hot or if the ramekins are placed too high in the oven. To avoid this, ensure the oven is at the correct temperature and that the water bath reaches halfway up the ramekins. Also, check for doneness by gently shaking the ramekins—there should be a slight jiggle in the center.
