Preheat the oven to 350F and line a loaf pan with parchment paper for easy clean up and to prevent sticking
Grate 1 small zucchini, with the peel on, and squeeze out the water between paper towels or a clean cloth. Grate enough to fill a 1 cup measuring cup, packed. Transfer it to a mixing bowl
Add in egg, almond butter, vanilla extract, maple syrup, apple cider vinegar and milk. Stir until everything is combined
Make oat flour in a food processor by grinding 1 cup of rolled or quick oats until fine. Add them to the mixing bowl, along with baking soda, sea salt, and cacao powder. Mix well until everything is combined
Transfer the batter to the prepared loaf pan and sprinkle the top with raw pumpkin seeds
Bake for 55 minutes, or until the center is cooked through. Use a toothpick to test it
Rest the pan on a cooling rack for at least 30 minutes before removing and slicing. TIP: It slices best when it is completely cool
