Spider Rice Krispie Treats

Why You’ll Love This Recipe

I like this recipe because it’s no-bake, super quick, and only takes about 10 minutes from start to finish. The chocolate flavor from cocoa powder gives the treats a nice dark color, making them look more like spiders. I also love how customizable they are—I can add candy eyes and pretzel stick legs for a fun, edible decoration that everyone finds adorable (and a little spooky).

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

1 box Rice Krispie cereals
1 stick unsalted butter
16 oz marshmallows
1 tablespoon unsweetened cocoa powder
Candy eyes
Pretzel sticks

Directions

1. I heat a large pot over medium-low heat and melt the butter and marshmallows together until smooth.

2. I remove the pot from heat and stir in the cocoa powder and Rice Krispie cereal, tossing until everything is evenly coated.

3. I transfer the mixture to a lined dish, spread it out, and let it cool for about 5 minutes.

4. Once cooled slightly, I grease my palms, scoop some of the mixture, and roll it into balls.

5. I insert broken pretzel sticks into the sides for spider legs.

6. I press two candy eyes onto the front of each ball to create the spider face.

7. I serve them immediately or store them for later.

Servings and Timing

This recipe makes about 12 spider treats. It takes just 5 minutes to prep, 5 minutes to cook, and is ready in 10 minutes total.

Variations

Sometimes I use Cocoa Krispies instead of adding cocoa powder for extra chocolate flavor. If I want a darker spider, I use brown food coloring. I’ve also decorated them with red icing mouths or added sprinkles for a more playful look. For a nutty twist, I mix in peanut butter with the melted marshmallows.

Storage/Reheating

I store these treats in an airtight container at room temperature for up to 3 days. They don’t need refrigeration, but I keep them away from heat so they don’t soften too much. I don’t reheat them, but if they get too hard, I microwave them for just a few seconds to soften slightly.
