Looking for an ooey-gooey treat to munch on for a sweet fix? These M&M Rice Krispie Treats are the perfect balance of crunchy, sticky, sweet, and chocolate!
A nostalgic treat with the addition of classic candy-coated chocolate M&M’s makes for a new twist on the humble Rice Krispie Treat.
As an environmental scientist, I am always trying to find ways to combat food waste, and cereal is one of those things I buy on sale, thinking they’ll be a great solution to busy mornings, but then forget about the box in the back of the pantry.
But when you add marshmallows and butter and candy-coated chocolate, you better believe no one in my family is letting these go to waste!
M&M Rice Krispie Treats Tips and Tricks
Use Unsalted Butter
Listen, I truly love a salt and chocolate moment, but you can definitely take it too far in this Rice Krispie treats recipe. Using salted butter makes these treats overall too salty.
If you want your Rice Krispie Treats a little saltier, it’s best to add some flaky salt on top at the end.
Outside of unsalted butter, here’s what else you’ll need for your M&M Rice Krispie Treats:
Keep It Low and Slow
Once you gather your ingredients, the first step is to melt your marshmallows and butter. Add them to a large pot and set your heat source to low. Stir frequently as the butter and marshmallows start to melt together.
Once your butter and marshmallows are completely melted, you should be left with a sticky paste.
Add Your Rice Krispies to the Pot
Adding your Rice Krispies directly to the pot means less clean-up! Remove the pot from heat, add your Rice Krispies, and use a spatula or wooden spoon to fold the cereal in until it is completely coated.
Green tip: Speaking of cleanup, if you have a dishwasher-use it! Comparing dishwashing to handwashing, using an efficient dishwasher uses 1/6th the amount of water to get your dishes clean!
Once you fold in your Rice Krispies, your mixture will start to harden to form Rice Krispie Treats. The quicker you transfer your mixture out of the pot and into your baking dish, the better!
That means that prepping your baking dish is key. You can opt for a 9″ x 13″ baking dish to get treats that are about 1 inch thick, or you can use a 9″ x 9″ square baking dish for thicker treats like the ones pictured.
Quick Note: Add parchment paper to the bottom to make it easier to lift out of your dish.
Be careful! Your mixture is hot! Use a spatula or wooden spoon to flatten it down into your baking tray.
Add Your M&M’s Last
It’s important to not allow the M&M’s to get too hot. The color on the candy coating can easily melt and spread, and the chocolate can melt, too. So, it’s best to add them last.
Add half of your mixture to your baking dish of choice and flatten it down with a spatula or spoon. Then, add roughly half of your M&M’s on top, trying your best to distribute them evenly.
Next, add the remaining Rice Krispie treat mixture, spread it out, and add the rest of the M&M’s to the top. At this point, I like to use a piece of parchment paper to place on top and press the Rice Krispie’s down flat to shape them perfectly.
Don’t Cut ‘Em ‘Til They’re Set
Once you’ve transferred your mixture to the baking dish, it will need to set completely. Give it an hour or so before removing it from the dish and cutting it into strips, roughly 2-inches by 2-inches.
To speed up the setting process, you can stick them in the refrigerator. That way, they’ll be set in about 45 minutes.
Should You Have Leftovers
Store your treats at room temperature for up to 3 days or in the refrigerator for a week! Make sure to seal them in an airtight container to avoid staleness.
To freeze, store cut pieces in an airtight freezer-safe bag and thaw before enjoying. They’ll keep in the freezer for up to two months.
