Step 1: Preheat your oven to 350°F (175°C). Grease and flour a loaf pan to keep your bread from sticking.
Step 2: In a large mixing bowl, combine the pumpkin puree, olive oil, maple syrup, brown sugar, eggs, and vanilla extract. Mix until well blended.
Step 3: In a separate bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger.
Step 4: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few lumps are okay!
Step 5: If you're feeling adventurous, fold in the chopped walnuts for an extra crunchy texture.
Step 6: Pour the batter into your prepared loaf pan and smooth the top with a spatula.
Step 7: Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Step 8: Once done, allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Notes
Wrap the cooled bread tightly in plastic wrap or aluminum foil to store. It can be kept at room temperature for about 3 days or frozen for up to 3 months.
