Peanut Butter Cookies Stuffed with Oreos

When I was remaking these Rolo Stuffed Peanut Butter Cookies last week, I got to thinking about what else I could stuff in a peanut butter cookie. Peanut Butter Cups came to mind, obviously, and then Oreos did. So I decided to do BOTH.

Later, as I was “testing” one of the cookies (because, you know, I have to eat everything, obviously #excuses), I started thinking about how I was going to work off said cookie. How I was bored with my workouts and needed something to push me. So I went and signed up for a half-marathon.

I think the sugar was clouding my brain…or something.

So, back to these cookies. They’re the perfect training snack because, peanut butter. It’s like eating GORP or something!

How to Make Extreme Oreo Stuffed Peanut Butter Cookies

Now, stuffing Oreos in cookies isn’t new. Picky-Palate pretty much invented it several years back and my friend Amy over at Belly Full started making them in muffin tins. They’re like a hunk of cookie, that’s for sure!

This peanut butter cookie is my absolute favorite recipe. It’s perfectly soft and gooey and very peanut buttery. And it’s easy to make too!

Once you have your dough, you mix in some peanut butter cups. TIP: if you’re using a stand mixer, you don’t even need to chop the peanut butter cups; it’ll do the work for you. If you’re using a hand mixer, you’ll want to give them a rough chop first.

You put 2 tablespoons of cookie dough in the bottom of a muffin pan. Then you put a full Oreo on top, cover it with 2 more tablespoons of cookie dough, and then sprinkle more chopped peanut butter cups on top.

These Extreme Oreo Stuffed Peanut Butter Cookies stay gooey and soft for a few days but I liked them best about 10 minutes after they came out of the oven. I used a knife to help me get them out of the pan and the Oreo inside was still warm and the peanut butter cups were melty.

Cookie heaven, I’m telling you. Someone needs to put one on a fishing rod and drive the half marathon in front of me, mmkay?

  1. Good luck with your training! I’m sure you’ll do great! Running at Disneyland has got to be loads of fun (as fun as running can get 🙂 ).

  2. Wow, these look great! Wish I had one now…although, I still have a few other goodies in my freezer! Can’t complain.
    xoxo

  3. These look amazing! And good luck with the half marathon prep- that’s a lot of running, you totally deserve these 🙂 Pinning!

  4. Whoa. Anything with “extreme” in the title is gonna be a total winner. These look beyond my wildest dreams. And now I want to eat them all. Except without signing up for a half marathon, because that seems kind of painful. But kudos to you for going there, girl! You’re gonna do great!
