You were invited to a potluck cook out – and you completely forgot. It starts in half an hour! You want to “wow” but really? You’ve got minutes to pull something together. I’m here to tell you, you can knock the socks of the potluckers with this recipe that takes less than 10 minutes to come together. And, hey, if you know how to make rice krispie squares, then you are already ahead of the game! (oh, and honestly – if you really only have minutes until a potluck and you already have these ingredients on hand – just grab the oreos and run out the door. I mean, let’s be real – you’ll be too busy grabbing kids’ shoes, yelling for the sunscreen, and hunting for your keys, am I right?) Let’s learn how to make this Cookies N Cream Marshmallow Bars Recipe!
Ingredients:
- Approx. 6 cups large marshmallows
- 4-5 sleeves of oreo cookies (about 1.5 regular sized packages or about 30 cookies)
- 1/8 cup butter
- White icing (opt.)
- Oreo crumbs (opt.)
- Mini chocolate chips (opt.)
Disclaimer #1: the actual number of oreos may or may not have mysteriously started to decrease as cookies inexplicably ended up in my mouth. It was the weirdest thing. That’s why it’s a good idea to just get two bags of oreos – you know, for emergency cookie shortages.
How To:
- Find a large, microwave-safe bowl and add in the marshmallows and butter. Microwave on high for about 1.5 minutes or until they puff up nice and poofy. Mine took almost 2 minutes.
- While the marshmallows are cooking, time to get those oreos going. If you have a food processor, you will pour those cookies in and pulse until they turn into coarse crumbs. Taste testing at this point is always helpful. If you don’t have a food processor (you are still a good person), just put the oreos in a large ziplock baggie and pummel those babies until you get the coarse crumbs.
- By now the marshmallows are done so take them from the microwave and stir in the butter until well combined. Then quickly add in the oreo cookie crumbs. Stir. You will want to work quickly at this point because it gets sticky. I was too busy getting this step done to stop and photograph it. I know you have imaginations – imagine me looking amazing in my domestic goddess apron, stirring cookie crumbs into marshmallows like a pro.
- Press the mixture into an 8X8 pan that has been lined with some wax paper. Yeah, it’s time for disclaimer #2: I made two big mistakes at this point in the recipe. First, I used a 9X13 pan. That made for mighty thin squares. Second, I lined with tin foil sprayed with cooking oil, which was okay but I know that waxed paper lining would have been divine. Learn from my mistakes – don’t repeat them!
- Now, your squares could be done at this point – just cut into squares and you are out the door in less than 5 minutes! But, hey, I wasn’t going to let the other delicious additions go to waste, so they were going on these babies. I first spread a layer of white icing (from a can – I mean, we’re
lazyin a hurry, right?) - Then top with the reserved cookie crumbs and the mini chocolate chips. Time to get our drool on!
- Cut into squares and enjoy the ooey-gooey-chocolatey-icingy-amazingness!
Yeah, mine were a little too thin (use that 8X8 pan, I tell ya!) so they were extra gooey, but WHOA NELLY! They were good. Like smack your neighbor good. (Disclaimer #3 – I do not advocate for anyone to smack their neighbor.)
If you make this in an 8X8 pan, it will make around 10-12 squares depending on how large you like your squares.
