Chewy oatmeal with sweetened condensed milk and chocolate makes a baked oatmeal bar that is perfect for dessert, a snack or a breakfast bar. If I had an amazing metabolism I would eat these M&M Oatmeal Cookie Bars for breakfast every morning!
Oatmeal and Chocolate Bars
Oats add a hearty flavor and chewiness to cookies and desserts that is almost irresistible! When I saw this Amish recipe for M&M and chocolate cookie bars with oatmeal I had to try it! Much like our delicious Loaded White Chocolate Cranberry Oatmeal Cookies, these bar cookies are packed with flavor but don’t overwhelm you with sweetness.
These cookie bars offer a nice spin on Monster Cookies by adding a layer of sweetened condensed milk and peanut butter. The oats keep the sugar from being overpowering and too sweet. The blend is just right and very enjoyable!
My mom is so good at making treats for the grandkids and she often made a nice after school snack for my brother and I. My middle schooler might eat these both after school and for breakfast from time to time. He loves carbs, so this is an easy way to help fill him up.
Another adult benefit of these cookies is that they take some effort to eat, it’s tough to be sneaky. Do you ever have cookies sitting around the kitchen and every time you walk by the cookie jar feel tempted to grab one? Well, the crumb topping makes too much of a mess to snitch a cookie bar. If you don’t get a plate there will be a mess, so that helps with self-control!
How to Make Chocolate & M&M Bars
- Mix oatmeal, brown sugar, baking soda, flour, salt, coconut.
- Use a fork or pastry blender to cut butter into the dry mixture until crumbly.
- Reserve 1 1/2 cups of crumb mixture and press what’s left into a greased 9 x 13-inch baking dish.
- Bake at 350°F for 10 minutes.
- Combine sweetened condensed milk and peanut butter.
- Spread over baked crust.
- Sprinkle chocolate chips and M&Ms evenly over top of oatmeal bars.
- Sprinkle reserved crumbs.
- Bake additional 20 minutes until golden brown.
Tips for Making M&M Bars
- Be sure that butter is softened, NOT melted
- A pastry blender isn’t required, a regular mixer can be used, just take time to get butter evenly distributed throughout the dry mixture
- If using a pastry cutter be sure that it is sturdy on top and has a good handle or it may not be a helpful tool
- I like to use my fingers to pat the crust into a flat layer in baking pan
- Regular or mini M&Ms can be used, I prefer mini because it spreads the flavor out more evenly
- If you’re on the fence about coconut give it a try, it’s delicious!
- These M&M Bars really taste great at any meal during the day

I wanted to let you know flour is listed in the step by step directions but it is not included in the list of ingredients. I made this recipe today and it was a complete disaster because of the flour missing.
Thanks so much for letting me know! I apologize for the inconvenience and wanted to let you know that the recipe card has been updated.
