Method

1. Preheat the oven to 350F. Line a cookie sheet with parchment or a nonstick pad and set aside.
2. Melt butter in the microwave or on the stove top and set aside to cool slightly.
3. In a large mixing bowl, whisk together the almond flour, coconut flour, Natvia, cinnamon and salt.
4. Add the egg whites, butter (which should be cool enough that you can hold your fingertip in it for 5-10 seconds without flinching) and vanilla, and stir until evenly combined. It sound be slightly sticky.
5. Fold in the chopped pecans.
6. Gather the batter into a ball and turn it out onto a cutting board. Let it rest on the cutting board for 5 minutes, which will allow the coconut flour to absorb the moisture completely.
7. Once the excess moisture has absorbed, roll the dough out into a disc approximately 1/2" thick. Use a biscuit cutter (or glass) to cut out circles of dough.
8. Transfer the cookies to the prepared cookie sheet, spacing them about 1" apart.
9. Gently press one pecan half into the center of each cookie.
10. Bake for 15-18 minutes, or until the edges are golden, remove from the oven and transfer cookies to a wire rack to cool completely and firm up before serving.
