Ingredients

12 Oreos
7 cups mini marshmallows
3 tablespoons unsalted butter
1/2 teaspoon salt (I use kosher salt)
5 cups rice krispies cereal

Instructions

Line a 9x9 square baking pan with wax paper, or parchment paper, leaving an overhang on two sides. Lightly spray with cooking spray. Set aside.
* You can also just spray the pan with cooking spray if wanted.
Chop the Oreo cookies into larger pieces and not fine crumbs. I cut one cookie into about 4 pieces, and then I leave a couple of the cookies halved for the top. Set aside for later.
Measure out the rice krispie cereal. Set aside.
In a large pot, over medium low heat, add the mini marshmallows, butter, and salt. Stir occasionally, and let it cook until the marshmallows are completely smooth and the butter is melted.
Remove from the heat. Add the rice krispie cereal and use a rubber spatula to mix it well until all the cereal is coated in the gooey marshmallow mixture.
Mix in half of the chopped Oreo cookies. Add the other half and mix until combined.
* I like to reserve some pieces for the top of the krispie treats.
Dump the rice krispie mixture into the prepared baking pan. Get your hands very lightly wet, and use them to gently press the mixture into the pan.
Let them set at room temperature, for about 1-2 hours, before cutting into squares and eating.
* Life out with the overhang of the wax paper or parchment paper.

Notes

Butter : If using salted butter, reduce the salt by half (1/4 teaspoon).

Variations : There are a few ways to switch this recipe up if wanted.

For thicker bars use a 8x8 baking pan.
I like to add an additional 1 cup of mini marshmallows in with the cereal.
Add a layer of Oreo cookies in the middle by pressing half the mixture into the pan, adding a layer of cookies, and then adding the remaining rice krispie mixture over top and press down.
Use any variety of Oreo cookie you want!

Mini Marshmallows : You will need to buy the larger bag (16 oz) of mini marshmallows. You will need 7 cups and the smaller bag (10 oz) only has 6 cups of mini marshmallows in it. If weighting this ingredient, you will need 12 ounces of mini marshmallows which is equal to 7 cups.

Leftovers : These are best eaten the day of, and even better within a few hours of making them. Store any leftovers, at room temperature, in an air-tight container. They will lose their gooey softness and become firmer the longer they sit there.
