Ingredients
For the Crust:
1½ cups gluten-free oats
½ cup hazelnuts
1 tablespoon cacao powder
5 tablespoons coconut oil
2 tablespoons maple syrup
For the Filling:
1½ cans full-fat coconut milk
6 oz Lily’s Extremely Dark Chocolate (or stevia-sweetened/semi-sweet chocolate)
10 oz unsweetened dark chocolate (or unsweetened baking chocolate)
¼ cup maple syrup
2 tablespoons coconut oil
Instructions
- Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease an 8-inch springform pan with coconut oil and set aside. - Make the Crust:
 - In a food processor, pulse the oats, hazelnuts, and cacao powder until finely ground.
 - Add the maple syrup and coconut oil. Process again until the mixture forms a moist dough.
 - Press the mixture evenly into the bottom of the prepared pan.
 - Bake for 10–15 minutes, until lightly golden. Allow to cool for 15–20 minutes.
 - Prepare the Chocolate Mousse Filling:
 - In a saucepan over medium heat, combine coconut milk, maple syrup, and coconut oil. Stir until warm and combined.
 - Lower the heat and add both types of chocolate. Stir continuously until fully melted and smooth.
 - Let the mixture cool slightly for 5–10 minutes.
 - Assemble the Cake:
 - Pour the cooled chocolate mousse over the crust in the pan.
 - Smooth the top with a spatula if needed.
 - Chill to Set:
 - Refrigerate the cake for 2–3 hours, or until the mousse is firm to the touch.
 - Keep chilled until ready to serve.
 - Serve and Store:
 - Garnish with whipped coconut cream, shaved chocolate, berries, or chopped nuts if desired.
 - Store covered in the refrigerator for up to 2 days. Not recommended for freezing
 
Notes
- Substitute hazelnuts with sunflower seeds or more oats for a nut-free version.
 - Use semi-sweet chocolate or increase maple syrup for a sweeter mousse.
 - Add espresso powder or vanilla extract to enhance the flavor.
 - Individual servings can be made in silicone muffin molds.
 - If you don’t have a springform pan, line a standard cake pan with parchment for easy removal.
