M&M rice krispie treat ingredients

A bowl of large marshmallows, butter, mini m&m's and rice krispies on the counter.
  • Butter – Salted or unsalted butter both work for these treats.
  • Marshmallows – I used large marshmallows but you can also use mini marshmallows
  • Rice Krispies – Rice Krispies add a nice crunch, the store brand is fine too. 
  • Mini M&M’s – I used mini M&Ms but if you only have the full size you can use them and cut them in half or chop them. 

How to make M&M rice krispie treat recipe

Step 1: Add butter and marshmallows to a microwave safe bowl.  Microwave for 1 minute. Stir the ingredients together and microwave in 30-second intervals until the marshmallows are completely melted. Alternatively, you can melt on the stovetop over medium heat in a large saucepan

Step 2: Add KELLOGG’S® RICE KRISPIES® cereal. Stir until well-coated. Quickly stir in half of the M&M’s. Work quickly so the color from the candies does not bleed into the cereal mixture. 

Step 3: Using a rubber spatula coated with butter or wax paper evenly press the melted marshmallow mixture into a 13 x 9 x 2-inch baking dish or pan coated with non-stick cooking spray or lined with parchment paper.  Cool.

FAQ

Why are my M&M Rice Krispie treats not sticking together?

If your treats aren’t sticking together it could be because you over melted the marshmallows or the butter you used had too much water in it. 

Why are my homemade Rice Krispie treats so hard?

If the marshmallows get too hot this may result in hard Rice Krispie treats. 

Why won’t my marshmallows melt for my Rice Krispie treats?

If the marshmallows won’t melt it could be because they are too old. If they have been sitting around, especially in an open bag, they will get hard and difficult to melt. For the best results in making this classic Rice Krispie dessert buy a fresh bag.

How to store rice krispie treats

Rice Krispie treats can be stored in an airtight container in a cool dry place like on the kitchen counter for up to one week. 

Can I make m&m rice krispie treats ahead of time?

Prepare the Rice Krispie treats a few days ahead of time and store them on the kitchen counter. However I do have to say freshly made Rice Krispie treats taste the best. 

Rice krispie treat variations

  • Use a different candy: Instead of M&M candies, use a different colorful candy like Skittles. 
  • Mix in chocolate chips: Stir in dark, milk, semi-sweet, or white chocolate chips. 
  • Stir in peanut butter: Add a few tablespoons of peanut butter to the mixture to make peanut butter Rice Krispie treats. If you need nut-free treats for school events, use seed butter.
  • Drizzle with chocolate: Top the homemade rice krispie treats with a drizzle of melted chocolate for the perfect dessert.
  • Make them seasonal: For Halloween use orange colored candies, for Valentine’s Day choose pink or red candies for Christmas Rice Krispies treats use red and green. 
  • Top with extra marshmallows: Sprinkle mini-colored marshmallows on top of the treats.

Can M&M rice krispie treats be frozen?

Yes, you can freeze leftover rice krispie treats. Leftover treats can be frozen for up to 6 weeks. Freeze in individual portions in plastic wrap or a Ziploc bag so you can easily pull them out of the freezer one at a time.

Tips

  1. Room temperature – Let the Rice Krispie squares come to room temperature before storing them. 
  2. Add vanilla – To sweeten up the treats a touch, add some vanilla extract. 
  3. If you want a thicker bar, use a 9 x 9 pan instead of 9 x 13. Do not aggressive press the mixture into the pan. 
  4. Press lightly to keep the bars from becoming hard when it’s time to eat them.

    What a fun and colorful recipe! Gosh, I always forget about Rice Krispie Treats, but now you’ve just me taken back to childhood memories which seemed to often include these simple treats. I can’t tell you how long it is been since I’ve had one of these. So it looks like the weekend is calling for these to be made.
