Preheat your oven to 350°F (175°C).
In a food processor, combine the fresh cranberries, 1/4 cup of Monk Fruit sweetener, 1 tablespoon of lemon juice, and 1/8 teaspoon of salt. Process until the cranberries are finely chopped and well mixed, then set aside.
In a large mixing bowl or a stand mixer, combine the coconut flour, remaining 1/2 cup of Monk Fruit sweetener, xanthan gum, baking powder, and remaining 1/2 teaspoon of salt. Mix on low speed until all the dry ingredients are incorporated.
Add the softened butter, remaining 1 tablespoon of lemon juice, lemon zest, vanilla extract, and lemon liquid stevia to the dry mixture. Mix until a soft, uniform dough forms.
Feel free to taste the dough and adjust the sweetener if you desire more sweetness.
Gently stir in 1/4 cup of the chopped pistachios into the dough on low speed.
Roll the cookie dough into 24 small, evenly sized balls.
Place each dough ball onto a baking sheet lined with parchment paper or a silicone mat.
Lightly flatten each cookie with your palm or the bottom of a glass. Then, roll the outer edges of each flattened cookie in the remaining chopped pistachios to coat them nicely.
Bake for 12-14 minutes, or until the edges begin to turn a light golden brown.
Allow the cookies to cool completely on the baking sheet before transferring them. They will firm up as they cool, ensuring a perfect chewy texture.
