If your cookies turned out flatter than you'd like, there could be a few reasons: Too Much Liquid: Excess moisture from ingredients like pumpkin puree can make your cookies spread too much. Make sure you're measuring accurately. Warm Dough: If your cookie dough is too warm when it goes into the oven, it can spread out and result in flat cookies. Try chilling the dough for about 30 minutes before baking. Old Baking Soda: Baking soda that's past its prime won't give you the lift you're looking for. Make sure your baking soda is fresh for optimal rise. Oven Temperature: Make sure your oven is properly preheated. An oven that's too cool can cause cookies to spread before they have a chance to rise.
