Preheat oven to 350F degrees with racks in the middle.
Butter baking pan or mini tart pan.
In a large bowl combine the flour, 3/4 cup of the coconut, 1/2 cup of the sugar, and salt.
Stir in the melted butter and mix until dough is crumbly but no longer dusty looking.
Press into mini tarts. Bake for 15 minutes. Set aside.
While tart bottoms are baking, mix remaining coconut sugar mixture , and egg whites together until well.
Once bottom crust is out of oven, drop a few chocolate chips followed by 2-3 cherry halves in each tart. Top with coconut mixture, using your hands to evenly arrange.
Bake for twenty minutes at 350 degrees or until coconut topping is golden brown.
Cool a few minutes and remove from tart pan. I used a silicone tart pan, which made this very easy.
