Preheat your oven to 350°F and grease a 9x5-inch loaf pan with a small amount of coconut oil.
Place the bananas and cottage cheese into a high-speed blender and process until the mixture is completely smooth and creamy.
In a large mixing bowl, whisk together the eggs, liquid egg whites, Greek yogurt, and vanilla extract until fully combined.
Stir the blended banana and cottage cheese mixture into the bowl with the egg mixture.
Add the oat flour, almond flour, chia seeds, 0.75 cup of the hemp hearts, cinnamon, sea salt, and baking soda to the wet ingredients.
Gently fold the dry ingredients into the wet using a spatula until a thick batter forms and no dry pockets remain.
Transfer the batter into the prepared loaf pan and sprinkle the remaining 0.25 cup of hemp hearts and the pumpkin seeds evenly over the top.
Bake for 60 to 70 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
Let the loaf cool in the pan for at least 20 minutes before transferring it to a wire rack to cool completely.
Slice the loaf into 10 even portions and serve immediately or store in the refrigerator for a quick high-protein meal.
