Preheat the oven to 175 ° C. Cover the baking tray with baking paper.
Mix the flour, baking soda, baking powder, cinnamon, nutmeg and a pinch of salt.
In an additional bowl use a mixer to blend the sugar and butter until frothy. Gradually add the pumpkin, egg and vanilla extract until well blended.
Include the flour mixture until smooth dough arises.
Using a tablespoon, place the dough on the baking tray in portions (about 35 cookies).
Bake in preheated oven for about 15-18 minutes (until edges become firm).
Remove from the oven and allow to cool for 2 minutes. Transfer cookies to a wire rack to cool completely.
If you want, you can also decorate the pumpkin cookies with icing.
