Lightly brush melted coconut oil on the sides of a mini tart pan or muffin tin. You can also use cupcake liners in a muffin tin, if you’d like.
Mix together the crust ingredients in a food processor until the mixture resembles crumbs.
Take a bit of the crumb mixture and press it firmly into the bottom and sides of the pan. Repeat with the other 11 sections of the pan. Set the pan aside.
Mix all of the filling ingredients together in a high powered blender or food processer until smooth and creamy. Start with ½ cup of the coconut milk and add more later if you need it. If you’re using a high-speed blender and you’re worried about the mixture getting “stuck”, start on a low speed and gradually increase it. Turn it up the highest speed, and let it blend until completely smooth. It may struggle for a few seconds at the beginning, but once it gets going it should blend smoothly. If it seems too dry, add more coconut milk, a tablespoon at at time. Once the filling is smooth and creamy, pour it into the prepared crusts.
Place the pan in your fridge or freezer for an hour or two to let it set.
Garnish with zest and berries or pomegranate seeds, if using, right before serving.
