In a large bowl, combine all purpose flour, quick oats, baking powder, ground cinnamon, ground nutmeg, ground ginger and salt. Set aside.
In separate large bowl, mix butter and brown sugar, with an electric mixer on medium speed, until it is light and fluffy. Add an egg and vanilla extract and mix some more.
Then, add carrots and chopped pecans and continue to mix slowly adding dry ingredients. Mix until well combined. Leave in fridge for an hour.
Preheat oven to 350 F. Line two baking sheets with parchment paper. Take the dough out of the fridge and make balls using your hands (20-22 balls).
Place the balls in the baking sheets, already prepared. Space between the balls should be 1.5 inch. Bake for 10-12 minutes.
Take them out of the oven and let cool for a while, in the baking sheets, then place on a wire rack to cool completely.
Notes
Store them in a well sealed container, at a room temperature, for no longer than three days. If you prefer sweeter desserts, add a ¼ cup of sugar.
