Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the caramel layer:
1/2 cup allulose
1/4 cup water
For the custard:
1/2 cup allulose
2 cups unsweetened coconut milk or other milk of choice
4 large eggs, room temperature
1 teaspoon vanilla extract
1/4 teaspoon salt
Directions
Preheat your oven to 350°F (180°C). Lightly grease six small ramekins and set them aside.
Prepare the caramel by adding 1/2 cup allulose and water to a small saucepan. Heat over low heat until the sweetener dissolves completely. Increase the heat to medium and continue cooking while stirring occasionally until the mixture becomes golden amber in color.
Carefully pour the caramel mixture into the ramekins, swirling gently to coat the bottoms evenly.
In another saucepan, warm the coconut milk over low heat for a few minutes. Do not boil it.
In a large mixing bowl, whisk together the eggs, remaining allulose, vanilla extract, and salt until smooth.
Slowly pour the warm milk into the egg mixture while whisking continuously. This helps prevent the eggs from scrambling.
Strain the custard mixture through a fine mesh sieve for an extra silky texture.
Pour the custard evenly into the prepared ramekins.
Arrange the ramekins inside a deep baking dish. Carefully pour hot water into the baking dish until it reaches halfway up the sides of the ramekins. This water bath helps the flan bake evenly.
Bake for 35 to 40 minutes or until the centers are just set but still slightly jiggly.
Remove the ramekins from the water bath and let them cool to room temperature.
Refrigerate for at least 4 hours or overnight for the best texture.
To serve, run a knife around the edges and carefully invert each flan onto a serving plate.

Variations
Replace coconut milk with heavy cream for a richer texture.

Mix in a little orange zest for a citrus aroma.
Use almond milk for a lighter custard.
Add espresso powder to create a coffee-flavored flan.
Top with fresh berries before serving for extra freshness.
Storage/Reheating
Store leftover flan covered in the refrigerator for up to 1 week. Keep each ramekin tightly wrapped to maintain freshness and prevent odors from affecting the dessert.
For freezing, wrap the flan carefully and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
Flan is best served chilled, so reheating is usually unnecessary. If preferred slightly warm, allow it to sit at room temperature for about 15 minutes before serving.
FAQs
Can I make keto flan ahead of time?
Yes, keto flan is perfect for making ahead because it tastes even better after chilling overnight.
Why is my flan not smooth?
Overcooking or skipping the straining step can create a grainy texture.
Can I use a different sweetener?
Allulose works best because it caramelizes properly. Other sweeteners may not create the same caramel effect.
Do I need a water bath?
Yes, the water bath helps the custard cook gently and evenly.
Can I use dairy milk?
Yes, whole milk or heavy cream can be used if you are not avoiding dairy.
How do I know when the flan is done?
The edges should be set while the center still has a slight jiggle.
Can I make one large flan instead of individual ramekins?
Yes, but the baking time may need to be increased slightly.
Why did my caramel harden?
Caramel naturally hardens as it cools, but it will soften again once chilled with the custard.
Can I add toppings?
Fresh berries, whipped cream, or a sprinkle of cinnamon all work beautifully.
Is keto flan very sweet?
It has a balanced sweetness with a rich custard flavor rather than an overpowering sugary taste.
