Coffee flan is a delightful twist on the classic caramel custard: silky, smooth, and packed with bright coffee flavor. This version is easy to make and perfect for anyone who wants a caffeinated dessert.
I love caramel flan, and I’ve set out to recreate many of its variations at home. There are so many delicious takes — from orange and mocha to pumpkin, cream cheese, pineapple, and dulce de leche — and this coffee flan is the perfect start to that series.
This coffee-flavored custard is softer than the classic Filipino leche flan because it uses whole eggs. The texture is tender and slightly more delicate due to the inclusion of egg whites, which makes it a light, satisfying dessert with a strong coffee kick.
One smart shortcut in this recipe is making the caramel in the microwave — quick, simple, and effective. With a few straightforward steps you’ll have a glossy caramel base and a creamy coffee custard ready to chill and serve.
Recipe overview
- Make the caramel in the microwave and coat the bottom of llaneras or ramekins.
- Whisk the eggs gently, then mix in the sweetened condensed milk and evaporated milk.
- Strain the custard to remove any stray whites, then add dissolved instant coffee, vanilla, and a pinch of salt.
- Pour the custard into the caramel-lined molds, cover with foil, and bake in a water bath until mostly set.
- Cool completely, refrigerate to firm up, invert onto a plate, and serve.
Because this custard uses whole eggs, it will be less dense than yolk-only leche flan and can develop bubbles. The techniques below help keep the texture smooth and uniform.
How to make flan smooth
- Mix gently: Stir eggs and milk in one direction and avoid vigorous beating to minimize air incorporation.
- Strain the custard: Use a fine-mesh sieve or cheesecloth to remove any bits of cooked egg or foam.
- If the mixture looks foamy, let it sit a few minutes to let bubbles dissipate.
- Cook gently: Use a water bath (bain marie) or a steamer and a moderate temperature so the custard sets slowly and evenly.
- Check doneness carefully: The flan is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs.
Cooking tips
- If you prefer a lighter custard, substitute regular milk for the evaporated milk.
- For a richer, denser flan, use only egg yolks (for example, 12 yolks instead of 6 whole eggs).
- A pinch of salt balances the coffee’s bitterness and brightens the overall flavor.
- Dissolve instant coffee granules in a tablespoon of warm water and let the coffee cool before adding it to the custard to avoid cooking the eggs.
How to store
- Let the custard cool completely, then refrigerate. Properly stored, it keeps well for up to 3 days.
- Keep the flan in the ramekins with foil or plastic wrap to preserve moisture and the caramel’s texture; invert only when ready to serve.
- If removed from the molds, place the flan in a container with a tight-fitting lid to prevent the caramel and custard from drying out.

- 2 tablespoons instant coffee granules
- 1 tablespoon warm water
- 1 teaspoon vanilla extract
- ⅛ teaspoon salt
Equipment
- 4 llaneras or 12 ramekins
Instructions
- In a clear, microwave-safe bowl combine the water and sugar and stir until the sugar dissolves.
- Microwave on high about 4 to 5 minutes or until the mixture turns a honey-gold color. Immediately pour into llaneras or ramekins and swirl to coat the bottom.
- In a bowl, gently whisk the eggs until streaks of white disappear.
- Stir in the sweetened condensed milk until combined.
- Add the evaporated milk and stir until well combined.
- Strain the custard mixture through a fine-mesh sieve or cheesecloth to remove any solids or foam.
- In a small bowl, dissolve the instant coffee in the warm water. Let it cool completely.
- Add the cooled coffee, vanilla, and salt to the strained custard and stir gently to combine.
- Pour the custard into the prepared molds. Cover each ramekin with foil and arrange them in a wide, oven-safe dish with about 1 inch of water (water bath).
- Bake in a 375°F oven for about 40 to 50 minutes, or until a toothpick inserted in the center comes out clean.
- Remove from the oven, cool to room temperature, then refrigerate to fully set.
- To serve, invert each flan onto a plate so the caramel is on top.
