- ¼ cup butter
- 8 cups mini marshmallows (about 14 ounces), divided
- 6 cups Rice Krispies cereal

- Step 4: Stir in the regular sized M&M candies to combine.
- Step 5: Spread the mixture into a greased 9×9-inch baking dish. Use a piece of greased wax paper to press the mixture gently and evenly into the pan.

Tips & Variations

- Try swapping the milk chocolate chips for white or dark chocolate for a different flavor.
- For extra crunch, add chopped nuts or pretzels to the cereal mixture before setting.
Storage
Store M&M Rice Krispies Treats in an airtight container at room temperature for up to 3 days. To keep them fresh longer, you can refrigerate and bring to room temperature before serving. Avoid airtight storage in the refrigerator to prevent them from becoming too hard. Reheating is not recommended, as it can melt the candy and change the texture.

FAQs
Can I use regular sized marshmallows instead of mini marshmallows?
Yes, you can substitute regular-sized marshmallows with the same total volume or weight, but mini marshmallows melt more evenly and quickly for this recipe.
What if I don’t have M&Ms—can I use another candy?
Absolutely! Chocolate chips, Reese’s Pieces, or chopped candy bars work well as alternatives and add a tasty twist to the treats.
