Pre-heat oven to 350F. Line a cookie sheet with parchment paper and set aside.
Place all ingredients, except pecan halves, in a food processor and process until the mixture begins to form a ball (note if the mixture is too runny, add a bit more flour, if too dry, add a bit of maple syrup or plant milk). Use a spoon or a cookie scoop to grab about 1 ½ tbsp of the mixture, roll into a ball with your hands and then flatten into a disk. Place on the prepared cookie sheet. Repeat with remaining dough 9 more times until the mixture is used up (to make 10 cookies). Gently press a pecan half into the top of each cookie.
Bake in a pre-heated oven for 20 mins. Remove from oven and cool on a rack. Enjoy!
