Grease out the muffin pan and preheat the oven to 350°F.
Take a bowl and mix flour, baking powder, and spices there.
In another bowl, put pumpkin puree, eggs, sugar, oil, and vanilla, and mix all of them.
Fold the dry mixture into the wet mixture until they fully combine.
Pour the batter into the muffin cups and let them bake for 20 to 22 minutes.
