Preheat oven to 350°F. Lightly coat a loaf pan with non-stick spray and line it with parchment paper.
In a large mixing bowl, combine pumpkin, almond butter, coconut sugar, eggs, and vanilla extract until well mixed.
Add almond flour, coconut flour, baking powder, baking soda, pumpkin pie spice, cinnamon, and sea salt to the same bowl. Mix until just combined.
Pour batter into the prepared loaf pan and sprinkle pepitas on top. Press them gently into the batter.
Bake for 45-50 minutes until golden brown and a toothpick inserted into the center comes out clean.
Let it cool for 20 minutes before slicing. Serve warm with butter, ice cream, or enjoy as is.
