M&M Rice Krispie Treats are a no-bake cereal bar packed with marshmallows, M&M candies, and a melted chocolate topping loaded with mini M&Ms. Five ingredients, 10 minutes of work, and zero baking required. These look and taste like they came from a fancy bakery!
You know those gourmet rice krispies treats you can buy at the bakery? They cost like $5 for a thick, chewy cereal bar and honestly, they’re hard to resist. But resist I will! No way can I justify $5 for a rice krispies treat. I just refuse.
So, we’re making a whole pan at home…the cost is much lower, they take less effort than driving to the local bakery, and everyone goes nuts for all the gooey goodness!
I’ve created lots of fun cereal treat recipes, like our Oreo Rice Krispies Treats and our Christmas Rice Krispies Treats. Of course, I’ve also made Fruity Pebbles Cookies and Lucky Charm Bars!
I’m kind of a master at the no bake treats at this point and one of my biggest tips is…pack as much marshmallow as possible into the bars.
No dry, crunchy treats for us – we want them ooey gooey and hard to resist!
The secret is in the method – you stir some of the marshmallows in after the melting phase and it gives you these perfect little pockets of goo.
Ingredient Notes:
Rice Krispies – The obvious choice, but pro tip – try swapping in Chex cereal sometime. 😉
Marshmallow – We prefer mini marshmallows in these treats. Some get melted, some get stirred in towards the end to create chewy bites throughout.
M&M Candies – You’ll need some regular M&M candies along with M&M Minis. The regular sized M&Ms get mixed into the treats, and the minis will go on top.
Milk Chocolate Chips – You’ll melt the chocolate to drizzle over the treats. All that chocolate will hold the M&M minis in place!
Helpful Tip!
Use the right sized dish…
In my other RKT recipes I use a 9×13 baking dish. For this recipe it’s important to use a 9×9 dish. We’re making these treats extra thick! If using a 9×13 you’ll probably need more chocolate and candy for topping.
How to Make Rice Krispies Treats:
Melt: To get started you’ll melt all but two cups of the marshmallows with some butter. Heat the butter in a sauce pan then stir in the marshmallows until they’ve melted. Remove the pan from the heat just after melting.
Note: It’s important that you don’t overheat the marshmallow mixture or you will end up with hard and crunchy treats instead of soft and chewy cereal bars!
Rice Krispies: Next you can start stirring in the Rice Krispies cereal along with the remaining two cups of the mini marshmallows. They’ll get a little melty but will mostly retain their shape in the treats.
M&Ms: Now for the candy! Add a cup of the regular sized M&M candies to the Rice Krispies treat mixture and stir those up until it’s all well combined. Don’t worry if they start to melt and bleed the colors – it’s going to work out just fine.
Spread: These are meant to be extra thick M&M Rice Krispies treats so use a greased 9×9 baking dish here. Spread the RKT mixture into the dish by pressing down gently with a greased piece of parchment paper.
Chocolate: We’re going all out and topping these treats with some melted chocolate! It’ll also act as the glue that’ll hold all those M&M minis in place. Drizzle it over the bars and spread it out in a smooth layer.
Finish: Almost done. We’re not stopping with the melted chocolate! While it’s still melty, start topping the treats with M&M minis. Push them down lightly into the chocolate. Go all out and cover the treats in M&M minis!
You’ll have to resist eating these for at least two hours! They’ll need time to cool down until they are proper Rice Krispies Treats that can be easily sliced into squares.
Storage:
Room temperature: Store in a sealed container for up to 2-3 days. You can go a bit longer, but the texture does change the longer they sit.
Freezer: Slice into bars, wrap individually in plastic wrap, and freeze in a sealed bag for up to 2-3 months. Thaw at room temperature before serving.
FAQs:
The most common culprit is overheating the marshmallows. Melt them over low heat and pull the pot off the stove the moment they’re just melted. The residual heat will finish the job.
Yes, but the bars will be thinner. You’ll also need more melted chocolate and M&Ms to cover the larger surface area.
