Preheat your oven to 350°F (180°C) and line a baking sheet with parchment paper to prevent sticking.
In a large mixing bowl, whisk together the pumpkin puree, melted butter, and sugar until the mixture is smooth and creamy.
Add the egg and vanilla extract to the bowl and whisk again until fully incorporated.
In a separate bowl, sift together the flour, spices, salt, and baking soda to evenly distribute the dry ingredients.
Gradually fold the dry ingredients into the wet pumpkin mixture, mixing gently until just combined; the dough will be thick and slightly sticky.
Using a spoon or cookie scoop, portion out rounds of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 12–14 minutes, or until the edges are golden brown and the centers look set.
Remove the baking sheet from the oven and let the cookies cool on the sheet for 5 minutes, allowing them to firm up slightly.
Transfer the cookies to a wire rack to cool completely, revealing their vibrant orange color and tender texture.
Once cooled, serve the pumpkin cookies as they are or enjoy them with a cup of cider for extra seasonal flair.
