Peanut Butter S’mores Cookies

Jump to Recipe

If you follow my Instagram, you might have noticed my impulse s’mores purchase on Memorial Day. It was like fate…I wasn’t planning on going to the store, I wasn’t planning on going to THAT store, I wasn’t planning on making s’mores, and then I saw that fateful combination, my very favorite of all the s’mores combos, and they all came home with me.

Well, I ended up having some leftover Reese’s Peanut Butter Cups, so I chopped them up and threw them into a batch of cookie dough along with some marshmallows. And they were so good that I knew I needed to share them with you guys, but this time around, I used the unwrapped Reese’s minis because they’re just the right size for something like this. Or snacking. You know.

You’re going to start with 2 3/4 cup all-purpose flour and some baking soda, baking powder, and table salt.

In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.

Next, you’ll need some brown sugar and white sugar (I’m always going to put more brown sugar in cookies. This it who I am.)

Grab 2 sticks of butter, 1/4 cup full-fat cream cheese, some vanilla, an egg, and an egg yolk. Well, don’t grab them; gently retrieve them and allow them to come to room temperature.

Add the egg and egg yolk, then add the vanilla and beat to combine. With the speed on low, gradually add the flour mixture. Add the peanut butter cups and mix until just combined.

Scoop by rounded tablespoons onto the prepared baking sheets.

Questions & Reviews

  1. These look fabulous! And I love the idea of PB in with a s’more. Can’t wait to try them!

  2. I can’t even tell you how much this is speaking to my pregnant stomach… I just finished a workout, so I can eat these, right?

  3. Recipes like this make me so sad. I have a couple of peanut butter haters in my family and my husband likes both peanut butter and chocolate, but not together. I know, right?! That would leave way too many cookies for me to eat by myself and the only way to ensure self-control is never to make them. I wish I could eat as many peanut butter s’mores cookies as I want AND be thin. Sigh.

  4. Who ever has left over peanut butter cups??? Laughing. What a fun cookie. My co-workers would clean this out in the first morning break!

  5. I read this post while I was up feeding my 2 month old baby at 3:00 am and then when I went back to sleep I dreamt about these cookies. Pretty sure that means I need to make them ASAP!

  6. These sound super fun! I’ll have to try these for my kids, they love peanut butter s’mores and I’m sure they would go nuts over these.

  7. These sounds amazing! Can you explain the purpose of the cream cheese? I’ve never seen it in a cookie recipe and wondered what it does. Not that I doubt your amazing recipe, just trying to learn!
