Preheat your oven to 350°F. Line a 9x5-inch loaf pan with parchment paper or lightly spray it with baking spray.
In a large bowl, sift and whisk together the all-purpose flour, pumpkin pie spice, cinnamon, baking soda, baking powder, and salt. Set aside.
1 1/2 cup (180 grams) All-purpose flour, 2 teaspoons Pumpkin pie spice, 1 teaspoon Cinnamon, 1 teaspoon Baking soda, 1 teaspoon Salt, 1/2 teaspoon Baking powder
In a separate bowl, whisk together the pumpkin purée, oil, granulated sugar, eggs, vanilla, and lukewarm water until smooth. Add the dry ingredients and gently fold everything together with a spatula until just combined and no lumps remain. Pour the batter into the prepared loaf pan and use a wet knife to make a shallow line down the center of the batter—this helps the loaf rise evenly.
1 cup (240 grams) Pure pumpkin puree, 1/3 cup Canola oil (or any neutral oil), 1 cup (200 grams) Granulated Sugar, 2 Eggs,, 1 1/2 teaspoons Vanilla extract, 1/4 cup Water,
In a small bowl, mix together the pumpkin seeds, chopped walnuts, brown sugar, maple syrup, and a pinch of cinnamon. Sprinkle this mixture evenly over the top of the batter.
3 tablespoons Pumpkin seeds, 2 tablespoons Chopped walnuts, 2 teaspoons Brown sugar, 1 tablespoon Maple syrup, 1/8 teaspoon Cinnamon
Bake for 50 to 60 minutes, or until a toothpick inserted in the center comes out clean. Let the loaf cool completely in the pan before slicing and serving.
