I initially planned on just baking these with mini chocolate chips and Christmas M&M’S, but after I transferred the cookie dough to the pan, I thought a pop of white chocolate chips would make it look even more festive.

So when I pressed the additional M&M’S and mini chocolate chips onto the top of the cookie dough bars, a trick I always use when making chocolate chip cookies or M&M’s cookies, I added some white chocolate chips too.

These baked up perfectly!

These cookie bars are getting me so excited for Christmas!
