Preheat oven to 375° F. Prepare the muffin tin by spraying each muffin cup with non-stick cooking spray, and set aside.
In a medium bowl, beat eggs and milk together using a fork. Add refried black beans, banana peppers, diced tomatoes, scallions, cilantro, and chili powder; mix until well combined.
Divide black bean egg mixture between each prepared muffin cup, place in oven and bake for approximately 20-25 minutes. Remove when the mixture is set and lightly browned. Let cool for 5 minutes before removing muffins from the pan. Enjoy!
