Easy Halloween Oreo Rice Krispies Treats

These Spooky Halloween Oreo Rice Krispies Treats are an easy party dessert made with gooey marshmallows, crispy cereal, crushed Oreo cookies and optional orange food colouring.

The dark Oreo pieces against the orange-tinted marshmallow cereal give the squares a fun Halloween look without making the recipe complicated.

Easy Halloween Party Treats

These Oreo Rice Krispies Treats are a simple Halloween dessert when you want something festive without a long baking project. The crushed Oreo pieces add chocolate flavour and a spooky black-and-orange look once the optional food colouring is mixed in.

The orange food colouring is completely optional. Leave it out if you prefer the classic marshmallow colour, or use a colouring that works for your household and any allergy or ingredient needs.

Spooky Halloween Rice Krispie Squares

The crushed Oreo pieces give the squares a speckled Halloween look, and keeping a few larger cookie chunks adds extra texture. You can cut the treats into small squares for a party tray or make larger bars for individual servings.

For the softest texture, press the mixture into the pan gently rather than packing it down firmly.

Oreo Variations

The original chocolate sandwich cookies give these treats the strongest black-and-orange Halloween contrast, but you can use another Oreo variety you enjoy.

You can also change the look with seasonal sprinkles or a drizzle of melted chocolate. If you add peanut butter or another nut ingredient, keep allergy needs in mind when serving a group.

How To Make Halloween Oreo Rice Krispies Treats

Cut Smaller Squares To Stretch The Batch

This recipe makes 24 small squares from a 9 x 13-inch pan. Cutting smaller portions works well for a Halloween dessert tray and can help reduce leftovers or half-eaten treats.

If you are serving a crowd, arrange the squares on a platter with a few other Halloween recipes so guests can sample more than one treat without needing oversized portions.

These Halloween Oreo Rice Krispies Treats are best served once fully cooled and cut. Store leftovers covered at room temperature for the best texture.

Ingredients

• 6 cups of Rice Krispies Cereal
• 4 tablespoons Butter
• 6 cups of mini marshmallows
• 5 to 7 drops orange food colouring
• 2 cups of crushed Oreo cookies with chunks

Instructions

1. Grease a 9 x 13 x 2-inch baking pan and set it aside.
2. Melt the butter in a large pot over low heat. Add the mini marshmallows and stir until completely melted and smooth.
3. Remove the pot from the heat. Stir in the orange food colouring, if using.
4. Add the Rice Krispies cereal and stir quickly until evenly coated.
5. Gently fold in the crushed Oreo cookies, leaving some larger chunks for texture.
6. Transfer the mixture to the prepared pan. Using a buttered spatula or a piece of parchment paper, press the mixture evenly into the pan without compacting it too firmly.
7. Let the treats cool completely at room temperature, then cut into 24 small squares and serve.

Notes

For softer treats, press the mixture into the pan gently rather than packing it down firmly. Store covered at room temperature for up to 2 days for the best texture.
