Mix flour, cocoa powder, and baking powder. In a separate bowl, mash bananas and stir in both sugars, then add sour cream and oil and whisk until smooth. Crack in your eggs one at a time and mix gently. Fold the dry mix into the wet, stir in the chocolate chips (the best part!), then scoop into muffin cups. Bake at 350°F for 15–18 mins, let cool in the pan for 15 mins, then transfer to a rack—if your little one can wait that long!
