Instructions:

Preheat the oven to 350℉ (175 ℃). Grease a muffin tin or line it with paper liners. 

In a large bowl, whisk together pumpkin puree, granulated sugar, brown sugar, oil, eggs, and vanilla until smooth. 

In another bowl, mix together flour, baking powder, cinnamon nutmeg, and salt. Gradually add the dry ingredients to the pumpkin mixture, stirring until just combined. Divide the batter evenly among the muffin cups. 

Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean. Let cool slightly before serving.
