Instructions

Step 1 — Make the Keto Caramel

1. Combine ½ cup allulose and 2 tbsp water in a small saucepan.
2. Heat over medium, stirring occasionally, until caramel turns a golden amber (7–10 minutes).
3. Immediately pour into a 9” flan dish or individual ramekins.
4. Swirl to coat the bottom evenly, then sprinkle half of the chopped hazelnuts over caramel.

Step 2 — Prepare the Chocolate Hazelnut Custard

1. Preheat oven to 325°F (160°C).
2. Gently whisk 4 eggs in a bowl to combine; avoid frothing to maintain smooth texture.
3. Whisk in heavy cream, almond milk, ½ cup allulose, cocoa powder, chocolate chips, vanilla, and a pinch of salt until smooth.
4. Strain custard through a fine-mesh sieve for ultra-smooth texture.
5. Pour custard over caramel and hazelnuts in dish or ramekins.

Step 3 — Bake in a Water Bath

1. Place flan dish into a larger pan and fill the outer pan halfway with hot water.
2. Bake 45–60 minutes, until the center jiggles slightly like gelatin.

Step 4 — Chill & Serve

1. Cool to room temperature, then refrigerate at least 4 hours or overnight.
2. Run a knife around the edges, invert onto serving plates, and sprinkle remaining toasted hazelnuts on top.
3. Enjoy your decadent Chocolate Hazelnut Keto Flan.

Tips & Tricks

• Use a sieve when pouring custard to avoid any lumps and get that signature silky texture.
• Do not overwhisk eggs; too much air will create cracks.
• Allulose browns faster than sugar — remove from heat once amber to avoid bitterness.
• Ramekins are perfect for individual servings and faster chilling.
• For an extra smooth chocolate experience, melt chocolate chips into the warm custard slightly before baking.
