Preheat your oven to 350°F / 175°C and line a large baking sheet with parchment paper for easy cleanup. 2.
In a medium-sized mixing bowl, combine the softened butter, almond flour, salt, erythritol, vanilla extract, egg, and liquid stevia.
Using a hand mixer on low speed, blend the until they just start to come together. Increase the speed to medium and beat until the dough is smooth and fully combined. 3. Use a small cookie scoop (about 1. 5 tablespoons / 75 ml / 2.5 fl oz) to portion the dough onto the prepared baking sheet. Be sure to leave about 2 inches of space between each cookie to allow for spreading. 4. For a classic look, gently press a crisscross pattern onto the top of each cookie using the back of a fork. 5.
Bake for 12 to 14 minutes, or until the edges are a beautiful light golden brown. The centers will still look soft. 6. This is the most important step! Allow the cookies to cool completely on the baking sheet. They are very delicate when warm and will firm up to the perfect chewy texture as they cool.
Once cooled, store leftovers in an airtight container at room temperature for up to one week.
Do not overbake! The cookies will look slightly underdone in the center when you pull them from the oven. They will set and firm up perfectly as they cool on the pan.
Let the cookies cool completely on the baking sheet before attempting to move them. They are extremely fragile while hot and will crumble if handled too soon.
