For the best texture, do not pack the almond flour when measuring and avoid overmixing the dough once the dry ingredients are added. Chilling the dough is important to keep the cookies from spreading too thin and helps create a soft, lightly chewy center. If using erythritol and you notice a cooling aftertaste, try a monk fruit erythritol blend with a finer texture for a smoother sweetness. Store cooled cookies in an airtight container at room temperature for up to 5 days, or refrigerate for slightly longer storage. To freeze, place baked cookies in a single layer on a tray until firm, then move them to a freezer bag for up to 3 months. You can also freeze scooped dough balls and bake from frozen, adding a couple of minutes to the baking time. To enjoy a warm, gooey cookie later, reheat a baked cookie in the microwave for 10 to 15 seconds just until the chocolate softens again.
