M&M Chocolate Bars

One of the best bar recipes you’ll ever try!! These M&M Chocolate Oat bars have layers of oats, a sweetened condensed milk and chocolate center topped with more oats and M&Ms.

We LOVE Baking with M&Ms – from M&M cookies to M&M cake mix cookie bars, M&M cookie cake– they’re the perfect addition to so many desserts. They’re also great to change up for holidays.

M&M Chocolate Bars

M&M Bars

I’ll pretty much take any excuse I can get to try out a new dessert. Recently, I decided to make some M&M Chocolate Oat Bars, which was a recipe from Betty Crocker, and they were a hit!! My husband took them to co-workers and he said they were gone in minutes.

Because they were so good and easy to make, they’ve now become one of our go-to desserts (along with our sheet cake and cookie bars). We love changing them up with different M&Ms and almost always serve them warm with ice cream!

They’re simple – they get rave reviews and they’re fun to change out with the holidays.

How to Make M&M Bars

How to Make M&M Chocolate Oat Bars

Since these have become go-to treats, we can literally make these with our eyes closed. They’re so easy!

Begin by preheating the oven to 350.

In a large bowl, mix oats, flour, brown sugar, salt and 1 cup softened butter with a spoon. Remove 1 cup of this mixture and set it aside. Press the remaining mixture into a greased 9×13 dish.

In a small pot, melt sweetened condensed milk, chocolate chips and 2 tablespoons of butter over low-medium heat. Stir constantly until chips are melted and everything is smooth.

Pour this mixture over the oats and spread evenly. Sprinkle reserve oat mixture over the top along with the M&Ms. Bake for about 25-30 minutes. Let cool for at least 15 minutes before cutting.

Storing + Toppings

To STORE these bars, just cover tightly with Saran wrap and place on the counter for up to 3 days. If needing to reheat, just do so in the microwave for about 15 seconds.

Other Bar Toppings. We think M&Ms are the perfect addition to these bars. There are other candies that work well including:

  • Toffee Bits
  • Other chocolate chips (white chocolate and butterscotch are great)
  • Reese’s Pieces
  • Sprinkles

more Variations

These bars are so easy to change up with the different toppings listed above, but also with the M&Ms. There are now so many different varieties and colors, that you can create custom M&M bars for every holiday. You can also change up the flavor based on the M&M used.

You can even use Peanut Butter M&Ms, and if you think they are too big you can crush them to add on top. In the picture above, you can see how we’ve made Valentine, Christmas and Easter M&M bars just by changing up the candy on top.

    Delicious!! Made these for my kids last night and they were a huge hit. Definitely will be making these more often. So good and easy.

  2. These look awesome! I’m baking treats to include in our free lunch summer program and I know the kids will love them! The question I have is if the chocolate layer solidifies or stays gooey. These need to be packed in the lunches to send home to the families we serve so gooey isn’t an option. Thanks so much for such yummy recipes! Can’t wait to hear from you!

    1. Oh how fun!! I’m so glad you are able to use this recipe for something like that. Yes, the chocolate solidifies a bit, but it’s a soft solid… if that makes sense. 😉 It solidifies enough so when it is cut into a bar, it keeps its shape and the chocolate doesn’t ooze out. You can also freeze the bars before which will help them stay solid and nice for packing into lunches. Best of luck!

  3. 5 stars
    These are always gone quickly. So delicious, and quick fix for your chocolate cravings. I switch back and forth between milk chocolate and semi sweet.

  4. 5 stars
    Absolutely one of my favorite recipe to make for the kids. They would gobble up the entire batch if I let them. So easy to make.
