Heat oven to 350°F. Lightly grease a 9-inch tart pan with a removable bottom.
Pulse cookies to fine crumbs. Stir in melted coconut oil and a pinch of salt until evenly moistened.
Press crumbs firmly into the pan, packing the bottom and sides. Bake 9–11 minutes, then cool on a rack.
Warm coconut milk in a small pot until steaming, not boiling.
Combine chopped chocolate, maple syrup, coconut oil, vanilla, espresso powder, and a pinch of salt in a bowl.
Pour hot coconut milk over the chocolate mixture. Let stand 2 minutes, then whisk until smooth and glossy.
Pour filling into the cooled crust. Tap gently to release air bubbles and smooth the top.
Chill uncovered until set, about 3 hours. Slice and top with fresh berries to serve.
Notes
Variation: Swap the cookie crust for a press-in almond crust (1 1/2 cups almond flour, 3 tbsp cocoa, 3 tbsp maple syrup, 3 tbsp melted coconut oil; press and bake 10 minutes). Add orange zest or a splash of almond extract for a flavor twist. Storage: Keep covered in the fridge up to 5 days or freeze slices for 1 month.This recipe is an original creation inspired by classic Easy Vegan Chocolate Tart Recipe flavors.
