I used a 12×14 pan since I don’t have a 10×15, it ran over in the oven and after baking 15 minutes it was still quite raw. Ended up baking it an additional 10 min. Tastes great, will make again in a deeper pan.

I’ve made this twice. Both times with natural PB and it turned out great. I only used 1 c. of choc. chips (no M&Ms) the first time and only 1 c. of M&Ms (no choc. chips) the second time and it was plenty!

This is a good gluten-free cookie bar. It is very rich. I used peanut butter chips in place of some of the chocolate chips. Yum.
