    Ingredients

    This easy rice krispie treat recipe is made with basic ingredients you can find in your local grocery store.

    Halloween rice krispie treats ingredients.

    Cocoa Krispies. Chocolate flavored cereal makes these chocolate rice krispie treats super chocolatey. You can use regular Rice Krispies cereal or a generic brand of plain or cocoa rice cereal.

    Semi-sweet chocolate chips. Chocolate chips melted with the marshmallows make these krispy treats super decadent. You can use dark chocolate, semi-sweet, or milk chocolate chips.

    Mini marshmallows. You'll need one 10 oz. bag of fresh mini marshmallows for the filling and another cup for the marshmallow spider web. You can substitute regular marshmallows ounce for ounce and cup for cup, they'll just take a little longer to melt.

    M&Ms. I use the Ghoul's Mix milk chocolate M&Ms, but you can use any kind -- dark chocolate, peanut, peanut butter, mini M&Ms ... no wrong answers here.

    Candy corn. Candy corn gives a festive fall flair to these crispy treats. If you're not a fan, add more M&Ms, festive sprinkles, or another favorite Halloween candy.

    Step-by-Step Instructions

    Before you begin: Pop the M&Ms into the freezer to keep them from melting when stirred into the warm rice krispie mixture.

    Step 1: Melt butter and chocolate chips in a large pot or Dutch oven over medium-low to medium heat. Be careful not to burn the chocolate -- you just want to melt it. Add the marshmallows and stir until melted. Remove from the heat.

    Step 2: Stir in the Cocoa Krispies until completely coated with the chocolate marshmallow mixture. Gently stir in the candy corn and M&Ms until completely incorporated.

    Step 3: Pour the cereal mixture into a pan lined with parchment paper or foil sprayed with cooking spray. Use buttered hands or a silicone spatula to gently and evenly spread out the mixture. Be careful not to compact the mixture or crush the M&Ms. Gently press M&Ms and candy corn on top of the cereal treats. Cool for at least an hour and cut into bars.

    Step 4: Make the marshmallow web. Microwave marshmallows in a small microwave-safe dish for about 30 seconds or until they puff up. Stir well. Cool until easy to handle.

    Step 5: With clean, dry hands, dip your fingertips into the melted marshmallow and spread it across each bar. Stick a couple of candy eyes on each bar. If the marshmallow starts to harden, pop it back into the microwave for about 5 seconds.

    These treats are best enjoyed right away -- especially with the marshmallow spider web.

    Expert Tips

    • Freeze the M&Ms for a few minutes before stirring into the warm mixture to keep them from melting.
    • Fresh marshmallows are the secret to the softest, gooeyest rice krispie treats.
    • For even more Halloween fun, toss in some Halloween sprinkles with the M&Ms and candy corn.
    • As an alternative to the marshmallow spider web, drizzle the tops with melted white chocolate.
    • If the melted marshmallow mixture starts to harden, warm it in the microwave for about 5 seconds.

    FAQs

    Can you make Rice Krispies treats ahead of time?

    These Halloween Rice Krispies treats are best served the same day. If you have any left over, store them in an airtight container at room temperature for a couple of days.
    Do not stack them -- the marshmallow topping sticks to plastic wrap, wax paper, and parchment paper.

    How long should rice krispie treats cool before cutting?

    Let chocolate rice krispie bars cool for at least one hour before cutting.

    How do you keep rice krispie treats from sticking to the pan?

    Grease the pan with non-stick spray or line the pan with parchment paper or aluminum foil sprayed with cooking spray.

    Instructions
     

    For the Rice Krispie Treats

    • Before you begin:
      • Set aside a few M&Ms and candy corn for topping.
      • Pop the remaining M&Ms into the freezer to keep them from melting when mixed with the warm cereal mixture.
      • Line an 8-inch, 9-inch, or similar sized pan with parchment or foil sprayed with cooking spray. Leave an overhang for easy removal.
    • Melt and stir butter and chocolate chips together in a large pot over medium-low to medium heat. Add the marshmallows, stir until melted. Remove the pot from the heat.
    • Stir in the cereal until completely coated in chocolate. Stir in the M&Ms and candy corn.
    • Use a spatula or buttered fingers to press the mixture into the prepared pan. Be gentle so you don't compact the cereal or crush the M&Ms.
      Press the reserved M&Ms and candy corn into the top of the treats.
      Cool for at least one hour and cut into squares or rectangles.

    For the Marshmallow Spider Web

    • Microwave 1 cup mini marshmallows for about 30 seconds or until puffed up. Stir to deflate. Wait a few minutes until the mixture is cool enough to handle.
    • Dip clean, dry fingertips into the marshmallow mixture and stretch them apart to create spider webs. Drape the spider webs across each bar.
      Stick candy eyes onto the marshmallow topping.
    • Serve the same day you make them. Store leftovers in a single layer in an airtight container for a couple of days.

    Notes

    • Freeze the M&Ms for a few minutes before stirring into the warm mixture to keep them from melting.
    • Fresh marshmallows are the secret to the softest, gooey-est rice krispie treats.
    • For even more Halloween fun, toss in some Halloween sprinkles with the M&Ms and candy corn.
    • As an alternative to the marshmallow spider web, drizzle the tops with melted white chocolate.
    • If the melted marshmallow mixture starts to harden, warm it in the microwave for about 5 seconds.
