Preheat the oven to 180C / 160C fan (350F / 320F fan).
Grease 3 (10cm x 5 cm) oven proof ramekins with butter.
Add ⅓ cup allulose + 2.5 tbsp water to a pan. Bring to a simmer and cook until golden brown, about 4 - 5 minutes. Careful not to burn. Spoon into the bottom of the ramekins.
In a clean saucepan, add the cream, almond milk and the remaining allulose. On a low heat, bring to a gentle simmer.
In a cup, whisk 2 eggs and 1 additional egg yolk with a fork to combine.
Remove the cream mix from the heat and whisk in the eggs, vanilla extract with a hand balloon whisk. Strain the mix using a fine sieve into the ramekins, pushing it through with the back of a spoon.
Place the ramekins in a large baking dish. Pour boiling water into the dish until about ⅓ of the way up the ramekins. Bake for about 45 minutes, until it is set on top, but still a little jiggly in the middle. Remove from the oven and allow to cool to room temperature. Place in the fridge for at least 4 hours or overnight to fully set.
To remove the creme caramels, use a knife to release the edges, cover with a plate and flip.
1.7g net carbs per serving. Makes 3 servings. DON'T OVERBAKE: Remove it from the oven once it is set on top, but still a little jiggly in the middle. Creme Caramel continues to cook even after you remove it from the oven. Store the flans in the fridge for up to 3 days. Alternatively, cool fully, then freeze for up to 3 months.I buy my allulose on a website called luckyvitamin.com.
