My family calls these bars "the world's chocolatiest brownies" and is more than happy to gobble up a batch whenever I make them. They're a deliciously merry part of our Christmas cookie collection.

The recipe makes the most of a handy packaged brownie mix, so they're fast to fix. If you don't have the mini M&Ms, use chocolate chips instead. Our kids love these rich fudgy squares with a scoop of ice cream.—Jennifer Trenhaile, Emerson, Nebraska
My family has enjoyed these bars as a potluck dessert, brown-bag treat and anytime snack many times throughout the years. Butterscotch or peanut butter chips can be used in place of the chocolate chips.
