Preheat oven to 350 degrees F (175 degrees C). Butter and flour a 8.5" by 4.5" loaf pan.
In a large bowl, whisk together the eggs and the pumpkin puree. Whisk in oil, yogurt, and the vanilla extract until smooth.
In another bowl combine the dry ingredients, flour, brown sugar, baking soda, salt, cinnamon, ginger and nutmeg. Add the dry ingredients to the pumpkin mixture and combine them together.
Pour batter into prepared loaf pan and bake for 60 to 65 minutes, or until a toothpick inserted into the center of the bread comes out clean. Mine took 63 minutes, but oven varies, so keep an eye on it.
Remove from oven and cool in the baking pan for about 20 minutes.
Remove from pan and cool another 10 minutes.
Enjoy!
