Our best-loved M&M chocolate bars have chewy layers of oats and chocolate studded with M&Ms – this top-requested dessert feeds a crowd!
Our go-to Dessert
We LOVE hosting and inviting friends and family over – and of course feeding them! Which is why we love bar desserts that feed a crowd, like our best-loved M&M chocolate bars!
This dessert is a go-to and requested ALL of the time! As mentioned before, they make several servings in one batch (15 in this one) and are easy to throw together (about 10 minutes prep).
And who doesn’t love M&Ms? You could even change it up and use your favorite flavor. We LOVE Baking with M&Ms – from M&M cookies to M&M cookie cake – they’re a delicious addition to so many desserts and the perfect addition to the chewy oats in this one.
Even our local firefighters love this treat and request it each year!
WHY WE LOVE IT:
- So easy – so yummy! They are so simple and delicious. EVERYONE asks for the recipe. They’re also great with ice cream.
- The perfect treat to change up. Use different M&Ms for different holidays (or birthdays!).
- Plan ahead of time. This treat can easily be made in advance which is great for busy days.

- 1½ cups quick-cooking rolled oats – also known as instant oats
- 1 cup packed light brown sugar – or dark brown sugar
- 1 teaspoon salt
- 1 cup plus 2 tablespoons unsalted butter softened, divided – see How to Soften Butter Quickly
- 1 (14-ounce) can sweetened condensed milk – NOT evaporated milk
- 1 (11.5-ounce) bag milk chocolate chips – or use semi-sweet or dark chocolate chips. Try peanut butter, white chocolate, or peanut butter chips.

How to Make M&M Chocolate Bars
- PREP. Preheat the oven to 350°F. Grease a 9-x-13-inch baking dish and set aside, or Line the Pan with Parchment Paper.
- OAT BATTER. In a large bowl, mix 1½ cups flour, 1½ cups oats, 1 cup brown sugar, 1 teaspoon salt and 1 cup butter with a spoon. Remove 1 cup of the mixture and set aside.
- Press the remaining oat mixture into the bottom of the prepared baking dish.
- CHOCOLATE LAYER. In a medium pot, combine 1 can of condensed milk, 1 bag of chocolate chips, and the remaining 2 tablespoons of butter over medium-low heat. Stir constantly until the chips are melted and everything is mixed well.
- Pour the melted chocolate mixture over the oat layer and spread evenly. Sprinkle the reserved 1 cup oat mixture over the chocolate.
- BAKE. Top with 1 cup plain M&M’s and bake for 25–30 minutes. Let cool completely in the pan before cutting.

Holy deliciousness- I could eat the whole pan!
Can’t stop eating these!! So yuMmy! I had to send half the pan with my husband to work so that i WOULDN’T eat anymore. He told me that people were calling them “crack” bars becuase they were so Addicting! Lol will definitely be making these again! But only when i have lots of people coming over 😉 thanks for the recipe!
LOL!! I know what you mean!! Thank you for sharing the recipe 🙂
I made the for all of the cousins tonight. These are so easy, and so delicious! Thanks!
I’m glad they liked them!! Thanks so much!
These look great, but how big is a bag chocolate chips? They come in different size packets! What weight did you use?
I don’t have to ounces in front of me, but it’s just the regular size bag. It’s not tiny, but it’s not the largest one. You can’t go wrong with chocolate chips, so It doesn’t have to be exact. It’s as little or as much as you like 🙂 Hope that helps!!
This is the perfect one for upcoming sunday :). Thank you Admin
Yes, or for me..anytime during the week 😉 Thanks and I hope you like them!
I made these and added a layer of PB on top of the oat before the chocolate, then topped with mini Reese’s Pieces-delicious for a PB fan. I’ve made them both ways, and with the PB layer & M&Ms on top, anyway they are YUMMY!
Oh, those sound delicious!! Thanks for sharing those ideas!
I made these for a holiday party last weekend. I knew they would be amazing just by looking at the ingredients…. but they exceeded my expectations! They are SO good! I must say, a little bar goes a looooong way. They make a rich and dense bar. So easy to make, and a new party favorite. Thank you for sharing this recipe!
I just made this recipe and it was awesome! I made a couple modifications and used Reese’s Pieces instead.
