Per one serving:
210 calories; 23 grams protein
30 grams chocolate protein powder
1 small extra ripe banana mashed (1/2 cup unsweetened applesauce works too)
1/4 teaspoon baking powder
1 pinch sea salt
egg whites from 1 large egg
Spray a (microwavable) mug or small bowl with nonstick cooking spray.
Combine all ingredients in mug and microwave for 30 seconds, stir and microwave for 1 minute, stir around batter again and microwave once more for 30 seconds. If cake still appears wet, microwave for about 15-30 more seconds.
Enjoy straight from your mug or transfer to a small plate and top with fresh fruit, Greek yogurt, whipped topping
**Nutritional information will vary some, depending on brand of protein powder used.
I also tried substituting the mashed banana for 1/2 cup unsweetened applesauce. It worked really well, but was less sweet.
