Cookies and Cream Rice Krispie Treats Recipe
Introduction
These Cookies and Cream Rice Krispie Treats are a delicious twist on the classic marshmallow snack. Packed with crunchy Oreo pieces, they add a fun and flavorful surprise to a beloved treat.

Ingredients
- 6 tablespoons salted butter
- 16 ounces mini marshmallows (1 large bag)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 6 cups Rice Krispies cereal
- 12 Oreos (crushed)
Instructions
- Step 1: Crush the Oreos into chunky pieces by placing them in a zip-top bag and gently hitting them with a meat mallet or rolling pin.
- Step 2: In a large pot, melt the butter over medium heat.
- Step 3: Once the butter is melted, add the marshmallows and stir continuously until completely melted and smooth. Stir in the vanilla extract and salt.
- Step 4: Remove the pot from heat and fold in the Rice Krispies cereal until evenly coated. Then gently stir in the crushed Oreo pieces.
- Step 5: Lightly spray an 8×8 or 9×9 inch baking dish with cooking spray. Spoon the mixture into the pan and gently press it down with the back of a spatula or greased hands to create an even layer.
- Step 6: Let the treats chill at room temperature for 20-30 minutes, or refrigerate for 10-15 minutes until set. Cut into 12 regular-sized bars or 9 larger treats.
Tips & Variations
- For extra crunch, add chopped nuts or chocolate chips along with the Oreo pieces.
- Use white chocolate-covered Oreos for a sweeter variation.
- Greasing your hands prevents sticking when pressing the mixture into the pan.
- Try using gluten-free Rice Krispies for a gluten-free treat option.
Storage
Store the treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Reheat gently in the microwave for 10-15 seconds if you prefer them warm and gooey.

FAQs
Can I use regular marshmallows instead of mini marshmallows?
Yes, you can use regular marshmallows. The melting time may be slightly longer, so stir until smooth and fully melted before adding other ingredients.
How do I prevent the treats from sticking to my hands or spatula?
Grease your hands or spatula lightly with butter or cooking spray before pressing the mixture into the pan. This helps avoid sticking and makes shaping easier.

Main Ingredients
- 6 cups Rice Krispies cereal
- 12 Oreos, crushed
Instructions
