Combine the butter, almond flour, coconut flour, sweetener, gelatin, and vanilla in the food processor and pulse until it comes together in a ball of dough. Divide into 28 balls and roll each in the coconut. Put on a parchment-lined lined baking sheet and press down making a little well with your thumbs.
Bake for 14-17 minutes or until lightly browned around the edges. Use a small upside down measuring spoon to press down the center of each cookie. Put ½ teaspoon of jam into the well of each cookie. Cool completely. Store in the fridge.
Notes
This dough can seem dry when processing in the food processor. Don't worry! Just keep the machine running until it comes back together into a ball.I used Polaner All Fruit Peach, Strawberry, and Blueberry Jams. You only put ½ teaspoon on each cookie. This type of jam adds about 1.33 carbs per cookie. Using a reduced carb jam will reduce that number even more.Notes on Sweeteners:
