Why You’ll Love These Halloween rice krispies

key ingredients
- Rice Krispie cereal or crispy rice cereal: The main ingredient and base of this recipe. Any rice krispie brand will work.
- Mini marshmallows: You’ll need 10 ounces of mini marshmallows plus 2 cups to make extra gooey treats. The marshmallows will melt and bind the other ingredients together. Mini marshmallows works best for this recipe as opposed to the large marshmallows.
- M&Ms: Adds a chocolatey twist! You could also use chocolate chips instead.
- Halloween sprinkles: Makes these treats festive and fun. I love using sprinkles with candy eyes otherwise I love to add them in to make them spooky looking.

how to make halloween rice krispie treats
Prepare baking dish: Line a 13×9 inch pan with foil or parchment paper and grease with butter, coconut oil or nonstick cooking spray.
Melt butter: Bring a large pot or stock pot to medium heat. Add butter and melt.
Melt marshmallows: Reduce the heat to low heat and add mini marshmallows. Stir until melted, then add vanilla extract.
Add in rice cereal: Remove the pot from heat and stir in the cereal until the marshmallow mixture completely coats the cereal.
Mix in 2 cups of mini marshmallows, M&Ms and sprinkles: Be sure not to stir too much or too long, otherwise the colors will start to melt.
Add the mixture to the prepared pan: Gently press the mixture into the pan. Don’t press too hard otherwise your treats will be too dense and hard. Top with more M&Ms and sprinkles (optional).
Cool and enjoy! Let cool for 20-30 minutes, then cut into squares and enjoy!

variations
- Brown the butter: If you’ve ever had Brown Butter Rice Krispie Treats, you already know how amazing they are. Follow the steps in this recipe to brown the butter first before adding the marshmallows. This will add a rich, caramel, nuttiness flavor to your treats.
- Alternative cereal: Chex cereal, Chocolate Cocoa Krispies, or Cheerios would also work since they don’t have any added flavors or colors.
- Make all year round: Use other themed M&Ms and sprinkles to celebrate other holidays like Easter, Thanksgiving and Christmas. Use rainbow colors to make any time of the year or to celebrate a birthday.
pro tips
- Spray your hands or rubber spatula: Use either cooking spray or rub them with butter before you press the rice krispie mixture on into your dish. This will prevent your hands from sticking to the sticky mixture. You can also use a butter wrap to press the mixture.
- Treat size: I use a 13×9 inch pan to yield 24 treats but you can also use a 8×8 or 9×9 inch baking dish if you want your bars to be thicker.
- Fall flavor: Add 1/2 teaspoon of pumpkin pie spice to make these taste like Fall! Add the spice to the melted marshmallow mixture.

faq
CAN YOU USE MARSHMALLOW FLUFF INSTEAD?
You can, however, I don’t recommend it because it will take away from the fluffiness and softness. It will also be extra sweet since extra sugar is added. I’ve never used marshmallow fluff so if you do try it, let me know. Fresh marshmallows are always best.
ARE RICE KRISPIES TREATS GLUTEN-FREE?
Although rice is gluten-free, some of the manufacturers make their crispy rice cereal with malt which contains gluten. If you want to make these gluten-free, be to check the cereal box packaging.
HOW TO KEEP TREATS SOFT?
Keep them away from the refrigerator as they will get hard and the marshmallows will loose their softness and gooeyness. You also want to store leftovers in a sealed airtight container and keep out as much air as possible.
CAN YOU FREEZE RICE KRISPIE TREATS?
Yes you can! However, it can cause them to be less soft and gooey so I do not recommend it. To freeze, place cooled treats in an airtight container and layer with a piece of parchment paper or wax paper to prevent them from sticking. Be sure to let the treats sit out at room temperature for at least 15 minutes or until softened before serving again. Store for up to 1 month.

leftovers & storage
To-store on counter: Place leftover rice krispie treats in an airtight container or cover a plate tightly with plastic wrap in a cool dry place. If you need to layer the bars, I recommend placing a piece of parchment paper or wax paper in between each layer. They will store for up to 3-4 days without tasting stale. You can also store in a large ziplock bag.
To-store in the refrigerator: These treats will last a bit longer if you store them in the refrigerator. They will store well for up to 1 week. Be sure to let sit out for at least 30 minutes because they will become hard.
