Set oven to 350 degrees + grease an 8-9 inch loaf pan with coconut oil.
Add the flax egg ingredients in a small dish and mix to combine. Set aside.
In a large bowl add your dry ingredients - flour, protein powder, baking powder, salt, and spices. Whisk to combine.
In a separate bowl, add the pumpkin purée, soy milk, coconut oil, light brown sugar, and the flax egg. Mix to combine then add into the dry ingredients. Mix until fully combined.
Pour mixture into your greased loaf pan and top with the mini vegan chocolate chips.
Bake for 1 hour then let cool for at least 10 minutes. Enjoy!
