This recipe came about from experimenting with Michael Ruhlman's book Ratio. Inspired by his muffin batter formula, I started playing around with simple recipes I could make for my family. I prefer to measure the majority of my ingredients by weight as I find it is much easier and proven to be more accurate and requires a few less dishes. My trick for nice fluffy muffins with good height is to bake for 5 minutes at a high heat to activate the baking powder and then continue baking at a lower heat. Mini chocolate chips give a better chocolate/bite ratio. It's always ok if more than 1/2 cup fall into the batter.
