Preheat oven to 325 degrees and line a baking sheet with parchment paper.
In a bowl, mix together oats, flour, baking powder, cinnamon, salt and collagen (if using). Set aside,
In a separate bowl, whisk together the coconut oil, egg, vanilla and maple syrup. Add the flour mixture to your wet ingredients and whisk to fully combine. Stir in the carrots and raisins. Chill in the fridge for up to 30 minutes.
Form dough into 1 inch balls and place on your baking sheet. Flatten them slightly with your hand. (These cookies DO NOT spread very much!) Bake for 13-15 minutes.
Place on a wire rack to cool.
