Preheat the oven to 360°F (180°C). Line a baking tray with parchment paper.
Whisk butter and sugar until light and fluffy. You can use a handheld wire whisk, an electric hand blender, or a stand mixer.
Add mashed bananas, egg, and vanilla extract, and whisk until combined.
Add all-purpose flour, baking soda, ground cinnamon, ground nutmeg, and ground cloves to the bowl and mix until combined. I use a silicone spatula at this stage to mix the ingredients.
Fold in the chopped pecans.
Using an ice cream scoop, drop the batter on the baking sheet, keeping a distance of 2 inches between each.
Tip - To make round cookies, gently shape the batter in between your palms.
Bake for 12-13 minutes until the cookies are nicely browned.
Transfer the cookies to a wire rack and let them cool completely. Enjoy!

Notes
You can use pumpkin pie mix instead of the ground spices I used in the recipe.
