In a medium bowl, stir together the coconut flour, collagen protein powder, cinnamon, salt, and mini chocolate chips.
Add the pumpkin puree, coconut oil, maple syrup, vanilla, and Stevia (if using) and stir together until a thick dough forms. The coconut oil should be soft when added but not melted.
Roll the dough into 1-inch balls - the dough shouldn't be sticky and should be easy to roll.
These have the best texture when stored at room temperature, but can be stored in the fridge and eaten chilled as well.
Enjoy!
Notes
You may need a different amount of liquid in this recipe depending on the protein powder you use. I haven't tried this recipe with other protein powders Collagen protein doesn't absorb a lot of water, so if you use a pea protein or brown rice protein you may have to add more liquid (maple syrup or coconut oil) 1 tablespoon at a time to get the consistency that is needed to roll these into balls
