Sugar-Free, Low-Carb Flan Recipe
Ingredients (Single Serving):
For the Caramel:
- 1 tablespoon allulose (or your preferred sugar-free sweetener)
- 2 drops stevia caramel flavoring (optional)
- 1/2 teaspoon water
For the Custard:
- 1 large egg
- 100 ml milk (about 1/3 cup; I recommend Fairlife Whole Milk for high protein and low sugar)
- 1 tablespoon allulose
- 1 tablespoon vanilla extract
Instructions:
1. Prepare the Caramel:
- Add 1 tablespoon of allulose to a ramekin.
- If using, add 2 drops of stevia caramel flavoring for extra depth.
- Stir in 1/2 teaspoon of water to dissolve the sweetener, creating a syrup-like consistency.
- Microwave the ramekin on high for 1–1.5 minutes, watching closely. The caramel will bubble and thicken.
- Remove from the microwave and let the caramel set while you prepare the custard.
2. Make the Custard:
- In a mixing bowl, whisk together 1 egg, 100 ml milk, 1 tablespoon allulose, and 1 tablespoon vanilla extract until completely smooth.
3. Assemble the Flan:
- Pour the custard mixture over the set caramel in the ramekin.
4. Cook the Flan:
- Microwave the ramekin individually on medium power (50%) for about 3 minutes.
- The flan is done when the custard is just set but still slightly jiggly in the center.
5. Chill the Flan:
- Refrigerate the flan for at least 30 minutes or overnight for best results.
6. Serve:
- Run a knife around the edges of the ramekin to loosen the flan.
- Invert onto a plate to release the flan with its caramel topping.
Tips for Success
- Use Medium Power: Cooking on medium power ensures the custard cooks evenly without overcooking.
- Watch the Caramel: Keep an eye on the caramel as it microwaves to prevent burning.
- Chill Well: Let the flan chill for at least 30 minutes to achieve the perfect texture.
- Scale Up: Multiply the ingredients for larger batches—just cook each ramekin individually in the microwave.
Why This Recipe Works
The combination of allulose and stevia caramel flavoring provides a sugar-free yet authentic caramel taste, while the custard remains rich and creamy thanks to high-quality milk and eggs.
