Mix in rolled oats with your dough for a chewy texture and a nutty flavor. Oatmeal pairs surprisingly well with M&Ms.
5. Vegan M&M Cookie Dough Bars

8. No-Bake Cookie Dough Bars

Use edible cookie dough made with heat-treated flour and omit the eggs. Add M&Ms for that signature crunch and color.
9. Brownie M&M Cookie Dough Bars

Can’t decide between a brownie and a cookie? Why not both? Layer brownie batter on the bottom and cookie dough with M&Ms on top.
Bake until the layers fuse into a gooey, chocolatey masterpiece.

Take your bars camping (figuratively) by adding graham cracker crumbs to the dough and topping with mini marshmallows and M&Ms.
Bake until the marshmallows are golden for that s’mores vibe without the campfire.
11. White Chocolate Cranberry M&M Bars
Add a festive twist with dried cranberries and white chocolate chips.
