Ingredients

For the Keto Caramel
- 1/3 cup keto granulated sweetener (erythritol or monk fruit)
- 2 tablespoons water
- 1 tablespoon butter
- 2 tablespoons heavy cream
For the Custard
- 4 large eggs
- 1 cup heavy cream
- 1 cup unsweetened almond milk
- 1/3 cup powdered keto sweetener
- 1 teaspoon vanilla extract
- Pinch of salt
Optional topping:
- Whipped cream
- Fresh berries (small amount for keto)

Step-by-Step Instructions
Follow these simple steps to make the perfect Keto Caramel Flan.
Step 1: Prepare the Caramel
In a small saucepan, combine:
- Keto sweetener
- Water
Heat over medium heat and stir gently. The mixture will start to melt and turn golden.
Once it becomes caramel-colored, add butter and heavy cream carefully. Stir until smooth.
Quickly pour the caramel into the bottom of small ramekins or a baking dish.
Tip: Work quickly because keto caramel hardens fast.
Step 2: Make the Custard Mixture
In a mixing bowl, whisk together:
- Eggs
- Heavy cream
- Almond milk
- Powdered sweetener
- Vanilla extract
- Pinch of salt
Whisk gently until the mixture becomes smooth and well combined.
Tip: Do not over-mix, or too many bubbles may form in the custard.
Step 3: Pour the Custard
Slowly pour the custard mixture over the caramel layer in each ramekin.
Make sure the caramel stays at the bottom.
Step 4: Prepare the Water Bath
Place the ramekins inside a large baking dish.
Fill the dish with hot water until it reaches halfway up the sides of the ramekins.
This method helps the Keto Caramel Flan cook evenly and stay smooth.
Step 5: Bake the Flan
Preheat your oven to 325°F (160°C).
Bake the flan for 35–40 minutes, or until the center is slightly set but still a little soft.
Tip: The custard will continue to firm up while cooling.
Step 6: Chill Before Serving
Let the flan cool at room temperature.
Then refrigerate for at least 3 hours, or overnight for the best texture.
To serve, run a knife around the edge and carefully flip the flan onto a plate.
The caramel sauce will flow beautifully over the custard.
Your homemade Keto Caramel Flan is now ready to enjoy!
Pro Tips & Variations

Use Powdered Sweetener

Add Extra Flavor
You can add:
