Step 1

Preheat the oven to 350ºF and position the rack in the center of the oven. Spray a 9x5 loaf pan with non-stick spray or line it with parchment paper. Set aside.

Step 2

In a large bowl, whisk together the flour, protein powder, granulated sweetener, cornstarch, pumpkin pie spice, cinnamon, baking powder, baking soda, and salt. Set aside.

Step 3

In a medium-sized bowl, whisk together the pumpkin puree, water, eggs, and melted butter.

Step 4

Pour the wet ingredients into the dry ingredients. Stir everything together with a spatula or large spoon until smooth and well incorporated. Do not over-mix.

Step 5

Pour the batter into the prepared loaf pan and sprinkle with the pumpkin seeds and turbinado if desired. Bake for 45-55 minutes or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

Step 6

Allow the bread to cool for 10 minutes in the pan before transferring it to a wire rack to cool completely. Slice and enjoy!
