Christmas Cookie Bar Tips

Whatever you do…Do not over bake these blondies! Under baking is the key to the best soft and chewy bars! The majority of the center will be under baked but it’s going to continue “baking” and firm up as it cools in the pan.
We added baking powder to give a little lift to the bars! If you don’t want the lift, leave it out of the bars.

Storing and Freezing M&M Cookie Bars
