How can I make my cookies less flat and more chewy?
You can try to chill the dough for at least 30 minutes before baking, use a slightly lower oven temperature, and avoid overmixing the dough. Make sure to use the right type of flour(all purpose or bread flour work well for chewy cookies), and add a extra moisture like honey or Greek yogurt to keep them soft. Finally, try baking them for a minute or two less than usual to ensure they retain their chewiness.
