Preheat oven to 350°F (180°C). Line a large baking sheet with parchment paper. Grease the paper with coconut oil. Set aside.
In a large bowl, combine sliced almonds, shredded coconut, almond flour, flaxseed meal, chopped pecans, salt, baking soda, erythritol, and cinnamon.
Make a well in the center of the dry ingredients and add in creamy peanut butter, vanilla and beaten egg.
Stir in until a cookie dough form. It will be difficult to stir with a spoon so you can use your hands to squeeze the dough and bring all the ingredients together. Wash/dry your hands, then lightly oil your hands.
Shape 9 cookie dough ball, one cookie ball is about 3 tablespoons each (40 g)
Place each cookie dough ball onto the prepared baking sheet, leaving a thumb space between each ball. Press each ball with your hand to flatten into a large round cookie. The thinner the crispier they will be!
The cookie will slightly expand in the oven but not much.
Bake 15-17 minutes or until the sides of the cookies are golden brown. They will be slightly soft and puffy in the center, that's normal they crisp after they cool down.
Remove from the oven and cool 10 minutes on the baking sheet, then slide a spatula under each cookie and transfer them one by one onto a cooling rack.
The cookies get their perfect texture after 1 hour and the best flavor after 3 hours or the next day when completely cool down.
Storage
Store in the pantry in a sealed cookie jar for up to 6 days or freeze individually in a zip bag and thaw on a rack 3 hour before at room temperature
Notes
Butter can replace melted coconut oil but the cookies will be softerXylitol is not a recommended sweetener for cookies, they soften cookies too much!
