Hi, I would like to recommend this muffin recipe because I am on diet and was really impressed by this recipe because it is made without oil or butter! I have made it twice and found it to be reliable and fun to make.

My stove is a little slow so I increased the temperature to 180ºC.
Truly a quick and easy recipe and very tasty when you are on a strict diet.
