Combine almond meal, coconut sugar, and zest in medium bowl.
Stir in melted butter.
Line cupcake tins with liners.
Divide evenly and press crumb mixture into the bottom of liners so there is a solid bottom, about 1/4".
Bake 10 minutes. After 10 minutes, remove from oven and set aside to cool while you make the filling.
Filling
Reduce the oven temperature to 325°F.
For the filling, use your stand mixer and beat the cream cheese until fluffy.
Add the coconut sugar and beat until thoroughly combined. Add the eggs, lemon juice, and zest, and vanilla. Beat just until smooth.
Pour filling into the prepared liners.
Bake at 325°F. until the center is just set, about 25 minutes. Transfer to a rack to cool slightly.
Glaze
While the cheesecake cups are baking, over medium heat in a saucepan, melt the coconut oil and maple syrup together, then stir in the almond butter, vanilla, and arrowroot starch until thoroughly combined.
Drizzle on top of cooled cheesecake cups. Finish with a sprinkle of sea salt.
Notes
If you overbeat the filling, it will become more like a soufflé. Beat just until the ingredients are combined.
