Preheat the oven to 350 degrees F. Grease and flour a 9x5 inch loaf pan.
In a large bowl, whisk together the pumpkin puree, oil, eggs, brown sugar, white sugar, and vanilla extract until completely blended.
In a separate bowl, sift together the gluten-free flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Add the dry ingredients to the wet ingredients and mix until just combined.
Pour the batter into the prepared loaf pan and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for 10 minutes before turning it out onto a wire rack to cool completely.
