01 - Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
02 - In a medium mixing bowl, whisk together almond flour, sweetener, baking soda, and salt until evenly combined.
03 - In a large bowl, mix sunflower seed butter, egg, melted butter, and vanilla extract until the mixture is smooth.
04 - Add dry ingredient mixture to wet ingredients and stir until a thick, uniform dough forms.
05 - Using a tablespoon or cookie scoop, portion dough onto the prepared baking sheet spaced 2 inches apart. Slightly flatten each dough mound with the back of a fork, creating a crisscross pattern if desired.
06 - Bake in preheated oven for 10 to 12 minutes, or until the edges are lightly golden.
07 - Leave cookies on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
