Preheat the oven to 350 °F (175 °C). Line a muffin pan with 10 muffin liners.
In a medium bowl, sift together the flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg.
1 cup (125 grams) flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, 1/4 teaspoon salt, 1 teaspoon ground cinnamon, 1/2 teaspoon ground ginger, 1/2 teaspoon ground nutmeg
In a larger bowl, whisk the eggs, pumpkin puree, sugar, and oil.
2 large eggs, 1 cup (240 grams) canned pumpkin puree, 1 cup (200 grams) brown sugar, 1/2 cup (120 ml) olive oil
Add the flour mixture to the wet mixture and stir just until combined. Do not over mix!
Divide the batter among the liners, filling each about 4/5 full, and bake for about 20 -24 minutes, or until a toothpick inserted in the center comes out clean.
