Peanut Butter Cup S’mores Bars

I have a confession … I’ve never really LOVED s’mores.

I know – that’s like saying I hate summer … but hear me out. I have never been a chocoholic, OR a big fan of marshmallows. So s’mores? I’ll take ’em or leave ’em.

But these bars. OMG. THESE BARS. There is no way that you’re not going to like these. Even B, another non-s’mores fan (yes, there are two of us and we found one another!), loves these bars. SO with the unofficial start of summer here, I decided to bring these bars to a Memorial Day BBQ and they did NOT disappoint. We got tons of compliments (yay!) and we will definitely be making these again. Enjoy!


Here’s what you need:

The Graham Cracker Crust:

  • 15 graham crackers, blended finely into graham cracker crumbs
  • 1 stick  butter, melted
  • 1/3 c. sugar

The Cookie Layer:

  • 1 ½ c all-purpose flour
  • ½ teaspoon salt
  • ½ teaspoon baking powder
  • 3/4 c firmly packed brown sugar
  • 3/4 c granulated sugar
  • 1 ½  cups (same as 1 1/2 sticks or 12 tbs) butter or margarine, softened
  • 2 eggs
  • 1 teaspoon vanilla extract
  • A 4.4 oz Hershey candy bar (the giant bar), broken up into chunks
  • 6 large Reese’s Peanut Butter Cups, chopped up into chunks
  • ½ c mini chocolate chips
  • 2 ½ cups mini marshmallows (1 ½ c to sprinkle on top, 1 c to add in batter)

Here’s what you do:

  1. Preheat your oven to 350 degrees.
  2. Crush the graham crackers in a food processor.  Combine with sugar and melted butter and press into a greased 9 x 13 inch pan.
  3. Bake the crust for 15 minutes.
  4. While the crust is baking, in a medium bowl, combine the flour, baking powder, and salt.
  5. In a large bowl of a stand mixer, combine the sugar and butter.  Add in the eggs and vanilla.  Add the flour mixture and gently stir in half of the Hershey candy bar chunks, half of the Reese’s chunks, the mini chocolate chips and 1 c. mini marshmallows.
  6. Carefully add the batter to the top of the graham cracker crust. I found it easiest to add big chunks in the corner of the pan and then carefully push the batter down with my hands so it is even. Be gentle – you don’t want to pull the crust apart. Don’t worry about making it perfectly even – it will spread as it’s baking.
  7. Press remaining candy (Reese’s and Hershey bar) on top of the bars. Sprinkle remaining marshmallows on top of the bars.
  8. Bake for 30 minutes or until marshmallows have started to brown/darken.  Allow to cool completely before cutting into them. I put mine in the fridge overnight before chopping them.
  9. Enjoy!
