For chewier cookies use an allulose-based sweetener, and for crisper edges opt for erythritol or a blend that contains erythritol. If your dough feels too soft to shape, chill it in the refrigerator for about 10 minutes before scooping. Be careful not to overbake; almond flour cookies firm up as they cool and can become dry if baked too long. To rewarm, place a cookie on a baking sheet in a 300°F oven for a few minutes until just warmed through. Always verify that your sugar-free chocolate chips and sweetener are truly low carb and free of added sugar to keep the recipe strictly keto.
