So, I’ve kind of been addicted to s’mores lately…and not the traditional kind. First, I made s’mores with Girl Scout Cookies. Now?

Now I’m making s’mores with Reese’s Peanut Butter Cups. You’re welcome.

Enter the best s’more ever: Peanut Butter Cookie Reese’s S’mores!

As you probably already guessed from, oh, the 5,000,000 posts on this blog with peanut butter in them, I’m totally addicted to the stuff. Cookies, brownies, pie, breakfast. I can’t. Get. Enough.

One of my favorite candies are REESE’S® Peanut Butter Cups, which I’m sure you probably guessed by now. If a bag of them is in my house, I will eat all of them, no joke.

I *think* somewhere there is a proven scientific fact that one bag of Reese’s Peanut Butter Cups (no matter the size) is only one serving. Come on, back me up on this…right?

Anyway, what’s better than a peanut butter cookie and a peanut butter cup? A s’more made with both.

These? Are totally drool worthy.

I know, right?

They’re super easy to make too: take two rich peanut butter cookies (from my favorite recipe) and then make a s’more. I used the broiler to make my s’mores by placing a mini peanut butter cup on one cookie and a marshmallow half on the other. You heat them under the broiler for just a few seconds (really, don’t walk away from the stove!) and then sandwich them together.

The peanut butter cup gets gooey and oozey. The marshmallow gets melty and sticky. These are the best s’mores ever!

You could totally do this over an open flame in the traditional method. But then I’d have to be, you know, camping. #idontdothat

You can make these any way you want, for any event you’d like. They’d be perfect treat to feed all your friends that come over and watch the big basketball games this month. You could even do what I did and make the cookies look like basketballs before baking.

Cute food + s’mores + peanut butter cups = WIN

Speaking of winning, I have a favor to ask of you.

The Reese’s Brand and Walmart are teaming up to give famillies great ideas for how to celebrate the big game by creating the REESE’S® Baking Bracket Challenge. I helped create one of 32 recipes that can be found at www.Reese’ Fans who vote for my recipe (this one!) will be entered to win a daily prize: a $100 Walmart gift card. {I’m not sure which bracket my recipe will be in, but I appreciate your help!}

Bring together your friends and family for some college basketball watching. It’s a great oppotunity for some fun and good food! Occasions like these are made even better with Reese’s proudcts, especially when they’re made affordable by shopping at Walmart. Find ideas and more Game Day Recipes on the Reese’s site!

But first, make these. Then go vote for me {shameless plug}.

Slam Dunk Peanut Butter Reese’s S’mores

No ratings yet


  • 1/2 cup butter softened
  • 3/4 cup peanut butter
  • 3/4 cup packed brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla
  • 1 tablespoon milk
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1 3/4 cups flour
  • About 12 large marshmallows cut in half
  • About 24 Reese’s Peanut Butter Cup Miniatures unwrapped


  • Preheat oven to 350°F. Line 2 cookie sheets with parchment or silpat baking mats.
  • Cream butter, peanut butter, and both sugars in the bowl of an electric mixer fitted with the paddle attachment. Add egg, vanilla, milk, and salt and baking soda. Mix until combined. Slowly add flour and mix until dough comes together.
  • Scoop 1 tablespoon sized balls of dough and place them on prepared cookie sheets, 2 inches apart. Gently press each ball with the palm of your hand to flatten. Using a spoon, make marks to resemble a basketball, if desired. (You can also make the criss cross marks with a fork instead.)
  • Bake for 8-10 minutes, until the bottoms begin to look brown. Cool at least 5 minutes on cookie sheets before removing to a rack to cool completely.
  • Assemble the s’mores: turn cookies upside down on a cookie sheet. Place large marshmallow halves on half the cookies and a peanut butter cup on the other half. Broil until the marshmallow is toasty and peanut butter cup is melty, under a minute. Make sandwiches and serve warm.
  • Note: You can also toast the marshmallows the old fashioned way: over an open fire!
