Preheat the oven to 350 degrees F. Lightly spray a large baking sheet with cooking spray (I use avocado oil spray) or line the cookie sheet with parchment paper.: As you heat to 350 degrees F , the kitchen will begin to smell faintly warm and you may notice a slight dry heat in the oven as it reaches temperature. Preheating is important because the immediate heat jump helps set the cookie edges while the centers remain tender, preventing flat or greasy cookies. A common mistake is putting cookies into an oven that is still cold, which leads to uneven bake and excessive spreading. Make sure the oven stirs no lingering moisture, and if you use parchment, it will sit flat and not ripple under the first batch.
Add the first 4 ingredients (egg through vanilla extract) to a mixing bowl and whisk well (note: you can also use a stand mixer). In a separate bowl, stir together the next 4 ingredients (almond flour through baking soda).: you can also use a stand mixer). In a separate bowl, stir together the next 4 ingredients (almond flour through baking soda). : The wet mixture of 1 large egg , 1/3 cup pureed pumpkin , 3 tbsp pure maple syrup , and 1 tsp pure vanilla extract will look glossy and slightly thick after whisking, with tiny air bubbles at the surface that indicate it is well combined. Mixing dry 2 cups finely ground almond flour , 1 1/2 tsp pumpkin pie spice , 1/2 tsp sea salt , and 1/4 tsp baking soda ensures even distribution of leavening and spice so pockets of salt or baking soda do not create hot spots. The reason to keep them separate initially is to avoid overmixing when combining liquids and fine almond flour, which can result in a denser cookie. A typical error here is beating the wet mixture too vigorously, which can introduce excess air and a less tender crumb when baked.
Pour the dry ingredients into the bowl with the wet and stir until combined. Fold in the chopped dark chocolate.: As you fold the bowl, the dough should come together into a cohesive, slightly sticky mass that holds shape when scooped. You will notice a speckled appearance from the pumpkin pie spice and a nuttier scent from the almond flour , and when you fold in the chopped dark chocolate , ribbons of deep brown will mingle through the dough. The 'why' behind gentle folding is to avoid overworking the almond flour , which can compress oils and lead to a grainier texture. A common pitfall is stirring too long, which can make the dough overly dense and reduce tenderness.
Drop cookie dough onto a large baking sheet in the same shape you want the cookies (the cookies will not rise or spread while they bake. I like to bake the dough in balls and then gently press them into a disc/cookie shape once they are finished baking).: When portioning, the dough will feel pliable but firm, and each mound keeps its shape on the large baking sheet . Because these cookies do not spread much, shaping them now is a choice based on desired final look. Baking them as rounded mounds yields a slightly domed, soft center, while pressing them into discs after baking gives a more uniform cookie look. Sensory clues include a slight tackiness when touched and visible chocolate pieces at the surface. Avoid overpacking the mounds, as compacting too tightly can yield a denser finished cookie.
Bake for 10 to 12 minutes, or until cookies reach desired level of done-ness.: During baking, you will see the edges set and a warm pumpkin aroma will intensify, while the top takes on a golden but not dark brown hue. The sound is subtle, but you might notice a faint settling noise as moisture escapes. The reason to watch closely between 10 to 12 minutes is to preserve tender centers while ensuring the edges are cooked through. If you leave them in too long, they can dry out and lose their soft, chewy character. A common mistake is removing them immediately; letting cookies rest briefly on the baking sheet allows carryover heat to finish the centers without overbaking.
