Preheat the oven to 350 degrees and mix together flour, baking powder, baking soda, cinnamon, and nutmeg. Make sure they are all well mixed and then set aside.
In a separate bowl, whisk together granulated sugar and brown sugar until there are no lumps.
Add canola oil and blend or whisk. If using your electric mixer, put it on medium and make sure you are catching the sides and bottom of the bowl.
Mix in eggs one at a time until well blended and then mix in pumpkin and vanilla. Make sure everything is well blended before moving on.
Slowly begin adding the flour mixture from the first bowl, a little at a time. Make sure to scrape the sides of the bowl again and the bottom.
Fill up your lined cupcake tins about 3/4 of the way up.
Bake for about 19 - 23 minutes. My oven tends to cook fast so I went with 19.
