This is a very basic recipe. The additions you can make are only limited by your imagination :-)
Replace the oil with peanut butter.
Replace sugar with ground nuts then sweeten with liquid stevia
Add a banana in place of the oil or in addition for moister muffins
Use maple syrup to sweeten
Add oatmeal in place of half the flour
Other good additions are nuts, seeds, dried fruit, chocolate chips etc.
