See recipe card for quantities.
- In a large sauce pan, on medium heat, melt butter and add mini marshmallows.
2. Mix until the marshmallows just melt. Remove from heat immediately.
3. Add in rice krispies to the marshmallow mixture. Mix until a sticky mixture forms.
4. Gently mix in halloween themed M&M's.
5. Press gooey mixture into a greased 9X13 baking pan. Gently press into place with parchment paper.
6. Once cool, cut into bars and serve!
Hint: Make sure to let the Halloween Rice Krispies sit before cutting into them. This will give the chocolate time to reset and not smash to make a chocolate mess.
- Gluten Free-to ensure this is a gluten free treat, use gluten free cereal.
- Jumbo Marshmallows - substitute mini marshmallows with jumbo marshmallows. Use a 10 ounce package or about 40 marshmallows.
- Marshmallow Fluff or Creme- Instead of mini marshmallows, use 7 ounces of marshmallow fluff. Once the butter is melted, remove from the heat and mix in the fluff. Once mixed add the cereal and candies.
- Sprinkles - add halloween themed sprinkles to the top of the dessert. Make sure to do it right away so they stick.
- Candy Corn - add ¼-1/2 cup of candy corn as well as the M&M's.
- Large Sauce Pan
- 9x13 baking pan
Cover the 9X13 baking pan and store at room temperature for 2-3 days for fresh taste. Use a lid if the baking pan has one or with plastic wrap or tin foil. If the dessert is not covered, the bars will harden and become hard to eat.
Make sure to let cool completely before covering to avoid the cereal and marshmallows from getting soggy.
Do not freeze.
Be careful when pressing the finished product into the 9X13 baking pan. The M&M's will be soft from the heat but will keep their form as long as pressure isn't applied to them. Be gentle when mixing them in and pressing into the baking pan.

A fun family halloween treat. They were just as easy as making regular rice Krispies but adding the Ghouls mix M&Ms made for such a fun spin. My kids loved them! I'm adding spooky eyes next time for more halloween fun.
