Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, combine almond flour, coconut flour, baking soda, and salt. In another bowl, whisk together melted coconut oil, honey (or maple syrup), and vanilla extract until smooth. Pour wet ingredients into dry mixture and stir until a dough forms.
Scoop tablespoon-sized portions of dough, roll into balls, and place on the baking sheet, spacing them 2 inches apart.
Press down in the center of each ball to create an indentation and fill with about 1/2 teaspoon of fruit preserves.
Bake for 12-15 minutes until edges are lightly golden. Let cool on the baking sheet for 5 minutes before transferring to a wire rack.
