Prep. Preheat oven to 350ºF. Grease a 9-inch loaf pan with baking spray and set aside.
Mix the dry ingredients. Place flour, baking soda, baking powder, salt, and spices in a large mixing bowl. Whisk until well combined. Set aside.
Mix the wet ingredients. In a separate mixing bowl, whisk together sugar and olive oil until well blended. Add eggs, pumpkin, and vanilla, and whisk until thoroughly incorporated.
Combine. Add the pumpkin mixture to the flour mixture and, using a wooden spoon, stir until combined. Stir in the pecans and let the batter stand for 15 minutes.
Bake. Pour the batter into the previously prepared loaf pan. Bake for 1 hour and 10 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
Cool. Remove the pumpkin bread from the oven and transfer it to a cooling rack. Cool in the pan for ten minutes; turn the bread out onto a rack and let it cool completely before cutting and serving.
Notes
Storage: Cool the quick bread completely before wrapping and freezing.
Freezing: To freeze, wrap securely in aluminum foil and place in freezer bags. When ready to bake, thaw completely at room temperature before baking.
