Preheat the oven to 325°F.
Line a baking sheet with parchment paper (or two pans if 24 cookies will not fit onto yours).
Mix almond flour, softened butter, coconut sugar, vanilla, and salt in a small bowl until a slightly crumbly but cohesive dough forms. Once combined, mix in chopped pecans.
Use a cookie scoop or spoon to measure out tablespoons of the dough and shape into balls, then flatten into rounds. Arrange the rounds as close as 1 inch apart on the sheet as they will spread very little. If you are placing pecans on top, press them gently into the dough before placing them into the oven.
To make the swirl patterns, take a spoonful of each dough, press the three spoonfuls together, form into a cylinder, then pinch off tablespoons of the cylinder. Form into balls and then flatten.
Bake the cookies for 20 minutes or until they start to turn light golden brown around the edges.
Remove from the oven and let cool on the pan for about 5 minutes. Transfer them to a rack to cool 10 minutes more.
If desired, place 2-3 tablespoons confectioners’ sugar in a shallow bowl and roll each cookie until coated.
Let cookies cool and enjoy.
Store any leftover cookies in the fridge to maintain crispness.
