For the Crust: In a medium-sized bowl, combine the almond flour, coconut flour, maple syrup, melted coconut oil, vanilla extract, and a pinch of salt. Mix well until the ingredients form a dough-like texture.
- Press the Crust: Press the crust mixture evenly into the bottom and up the sides of a tart pan (approximately 9 inches). Use your fingers to compact the mixture and create a smooth surface.
- Chill the Crust: Place the crust in the refrigerator for 15-20 minutes to firm up.
- For the Chocolate Filling: In a small saucepan, heat the coconut milk over medium heat until it just starts to simmer. Do not bring it to a boil.
- Melt the Chocolate: Remove the saucepan from the heat and add the chopped dark chocolate to the coconut milk. Stir gently until the chocolate is completely melted and smooth.
- Add Sweetener and Flavor: Stir in the maple syrup, vanilla extract, and a pinch of salt. Continue mixing until everything is well combined and the filling is smooth.
- Fill the Tart: Pour the chocolate filling into the prepared crust, spreading it evenly with a spatula.
- Chill the Tart: Refrigerate the tart for at least 2-3 hours, or until the filling has set and is firm to the touch.
- For Serving: Garnish the tart with fresh berries, shredded coconut, chopped nuts, or mint leaves, if desired. Slice and enjoy!
