Do you ever find yourself in a bind where you need to bring something to a potluck or just want an easy sweet? Well these Oreo Rice Krispie treats are the dessert you need for those situations. You only need a handful of basic ingredients and a few minutes to put together this fun twist on the classic treat.

My youngest nephew is allergic to peanuts and eggs so he is kind of limited in the dessert department. Oreos and rice krispie treats are his go-to foods. As a special treat for him I combined the two into this fantastic, ooey, gooey treat. They were a hit with him, his brother and sister, grandpa, me….everyone :).

ingredients to make Oreo Rice Krispies Treats

What You’ll Need

You don’t need much. These are four ingredient Rice Krispie treats!

  • Butter -Unsalted butter always works best for baked goods and desserts.
  • Marshmallows – We doubled up the marshmallows in this recipe!Adding the Oreos can dry out the treats a little so the added marshmallows help to keep the treats extra ooey gooey.
  • Rice Krispies – Name brand or generic rice cereal work the same.
  • Oreos – We used the classic Oreo for this recipe but you could use double stuffed or any of the flavors. I’d love to try lemon Oreo rice krispie treats!

How to Make It

Prep the butter and pan. Heat the butter over medium low heat in a large saucepan. While the butter melts, prepare a 13 x 9 inch pan with non-stick spray or rub additional butter everywhere on the pan. Set the pan aside.

Melt the marshmallows. When the butter has fully melted, stir in the marshmallows. Heat and stir them until they have fully melted. This will take about 5 to 7 minutes. You don’t need to stir constantly, but make sure you keep a close eye on them as it can burn easily.

Add the Rice Krispies and Oreos and Assemble. Once the marshmallows are completely melted, pour in the Rice Krispies and then the crushed Oreos. Stir it all together until the marshmallows coat everything. Lightly coat your hands in cooking spray or butter, and transfer the sticky treats to the greased pan. You can use your hands or a spatula to press them down until they form a solid layer.

Allow the treats to cool completely before cutting into squares, rectangles, or fun shapes and serving.

How do you keep Rice Krispie Treats from sticking to your hands?

This is a great trick. Before you start to work with treats, spray your hands with cooking spray. Yes, the same spray you use to keep foods from sticking when you bake or cook can keep your hands free from the sticky marshmallow. 

If you don’t have cooking spray on hand, you can also use butter. Neither adds any weird flavor.

Can I Make Them Ahead of Time? 

We make them ahead of time all the time. These are a great snack to bring on play dates, to get togethers, or at special requests of our loving nephew. When you make them ahead of time, allow them to cool completely and then place them in an airtight container. They should last about 5 to 7 days.
