Preheat your oven to 350°F (175°C) to ensure an evenly baked loaf.
In a large bowl, combine the pumpkin puree, sugar, brown sugar, and vegetable oil and mix these together until smooth.
Add in the eggs one at a time, ensuring each is well incorporated before adding the next, then stir in the vanilla extract.
In another bowl, whisk together the flour, baking soda, baking powder, ground ger, ground cinnamon, ground nutmeg, and salt to ensure an even distribution of those lovely spices throughout the batter.
Gradually add the dry ingredients into the wet mixture, stirring until just combined, being careful not to overmix; it's okay if there are a few lumps.
Grease a 9×5-inch loaf pan or line it with parchment paper for easy removal, then pour the batter into the prepared pan and spread it out evenly.
Place the loaf in the preheated oven and bake for about 55-60 minutes, or until a toothpick inserted into the center comes out clean.
Let it cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
Once cooled, slice your Pumpkin gerbread and enjoy it plain or with a spread of cream cheese or butter.
