Preheat oven to 325F and line a baking sheet with parchment paper.
In a large bowl, combine molasses, egg, sugar, and coconut oil. Once combined, add in the oat flour, protein powder, ginger, cinnamon, baking soda, and salt. Mix to combine.
Place 1 tablespoon of dough onto lined baking sheet, six per sheet since these spread. Bake in the preheated oven for 8-10 minutes, until edges are crispy but cookie remains slightly undercooked. Remove from oven and allow cookies to cool down to room temperature.
Notes
If you can't find the Chai Protein, you can use vanilla or plain protein. You'll have to adjust the spices to 1 teaspoon powdered ginger, 2 teaspoons cinnamon.
