Preheat oven to 375 degrees F. Spray 12 cup muffin tin with nonstick cooking spray or grease well with coconut oil
In a medium bowl whisk together oat bran, protein powder, baking soda, cinnamon, ginger, and cloves; set aside.
In a large bowl, mix pumpkin, applesauce, greek yogurt, egg whites, maple syrup and vanilla together until well combined and smooth.
Add wet ingredients to dry ingredients and mix until just combined. Fold in chocolate chips, then let batter sit two minutes to thicken a bit.
Divide batter evenly into 12 muffin cups and bake 18-23 minutes or until toothpick inserted into center comes out clean. Transfer to a wire rack to cool for 10 minutes, then remove muffins from tin and place on wire rack to cool completely.
Muffins are best served warm with your favorite spread.
Notes
You can leave the maple syrup out if desired, but the muffins won't have as much flavor. I sometimes do this, but add a little more chocolate chips.Feel free to sub the maple syrup with honey or agave nectar.I used whey protein powder for this recipe - it has about 90 calories per scoop an 20g of protein.These muffins are freezer-friendly!
