Ingredient Notes

• Rice Krispies cereal gives these treats their signature crunch, but any crispy rice cereal will work.
• Mini marshmallows melt quickly and evenly—don’t skip stirring constantly for the smoothest texture.
• Blue gel food coloring creates a vibrant Cookie Monster hue without thinning the mix like liquid food dye might.
• Use Chips Ahoy or another crunchy chocolate chip cookie brand—softer cookies may get too mushy in the mix.
• Oreos add that classic cookies-and-cream bite. Lightly crush them so you still get texture.
• White chocolate chips add extra sweetness and contrast beautifully against the blue.
• Candy eyes bring the Cookie Monster look to life—press them in while the treats are still warm.

Before You Make

Do I need to use gel food coloring?
Yes, gel food coloring works best here because it’s more concentrated and won’t change the texture of the marshmallow mixture like liquid coloring can.

Can I use different types of cookies?
Absolutely. While Chips Ahoy and Oreos are classic choices, feel free to swap in any crunchy cookies you like—just avoid soft or chewy ones, which can get soggy.

How do I keep the treats from sticking to the pan?
Spray your pan well with baking spray and press the mixture in using wax paper or a buttered spatula to prevent sticking.

FAQ

Can I make these Cookie Monster-Inspired Krispies Treats ahead of time?
Yes! They stay fresh for up to 3 days when stored in an airtight container at room temperature.

How do I make these treats extra gooey?
Use a full 10 oz bag of mini marshmallows and melt them gently on low heat to keep the texture soft and chewy.

Can I use natural food coloring instead of gel?
You can try it, but the color may be duller and you might need more, which can change the texture of the mix.

Do I need to refrigerate them?
Nope! These treats are best kept at room temperature—refrigerating them can make them too firm.

Can I cut these into shapes?
Yes! Once cooled slightly but still soft, use a cookie cutter to make monster heads, stars, or any fun shape.
