This tart features a unique crust made from sunflower seeds, oats, and buckwheat, lending a rustic and wholesome foundation to the creamy custard filling.

Instructions:

1. Prepare the Crust:
- Preheat your oven to 350°F (175°C).
- In a food processor, combine the sunflower seeds, oats, buckwheat flour, and cocoa powder. Pulse until the mixture forms a coarse meal.
- Add the maple syrup and coconut oil to the mixture in the food processor. Pulse until everything is well combined and the mixture holds together when pressed between your fingers.
- Transfer the mixture to a 9-inch tart pan with a removable bottom. Using your hands, press the mixture firmly and evenly across the bottom and up the sides of the pan.
- Bake the crust in the preheated oven for about 12–15 minutes, or until it's set and lightly golden. Remove from the oven and allow it to cool completely.
2. Prepare the Custard Filling:
- In a medium saucepan, combine the orange juice, egg yolk, and vanilla extract. Whisk together until thoroughly mixed.
- Gradually add the milk to the saucepan, whisking continuously to ensure everything is blended.
- Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens and coats the back of a spoon. This should take about 8–10 minutes. Be careful not to let it boil.
- Once thickened, remove the pan from the heat. Add the finely chopped dark chocolate immediately, stirring until the chocolate is fully melted and incorporated into the custard.
3. Assemble the Tart:
- Pour the custard filling into the cooled tart crust, spreading it evenly.
- Allow the tart to cool to room temperature, then refrigerate for at least 2 hours, or until the custard is set.
4. Serve:
- Once set, remove the tart from the refrigerator. Carefully remove the tart from the pan and place it on a serving platter.
- Slice and serve chilled. Enjoy your delicious bitter chocolate and orange custard tart!
