I wanted to keep these blondies simple, but full of flavor so I used a combination of different chocolate chips and crispy m&m's. They turned out PERFECT. There were slightly crunchy ends and perfectly chewy, not gooey, centers. I took them to my husband's office, and they were a HIT. People even said they wanted to marry someone who could make these, and I told them I could make it easy for them and just share the recipe on my blog!
