S’mores Cookie Bars

I was reminded of this yummy chocolate and marshmallow dessert recipe this summer when one of my dear friends called me with a question. Her daughter was getting married up in Michigan and she and her husband wanted to make these for a pre-wedding event at their gorgeous lakeside home. I had to shake the cobwebs out of my brain to remember when I first baked these bars.

This was well before Danielle and I were sharing each other’s recipes each month, but I knew it came from her blog, Hugs and Cookies XOXO. Well, apparently they were a success—whew. I can only imagine eating these glorious s’mores cookie bars while watching the sunset on the beach. I thought it was time for me to make them again!

Tips for Making S’mores Cookie Bars

  • I love making cookie bars for one specific reason. Instead of scooping out cookie after cookie, rolling the dough and baking one sheet then another, the bar cookie dough is pressed into a baking pan and popped in the oven. Of course, when the bars are layered, it’s a tad more work.
  • For this recipe, the base layer and crumble topping is the same mixture, so that saves a step. Plus, no extra bowls are needed for the marshmallow cream and Hershey bars filling. Whew.
  • I like lining my baking pans with non-stick aluminum foil. Besides preventing the bars from sticking to the pan, the non-stick foil doubles as a sling to help remove the bars from the pan to cut, plus it allows for easy cleanup!
  • If you don’t have non-stick aluminum foil, just line your pan with regular foil and spray with your favorite non-stick cooking spray.
  • PRO Tip: Use a wet knife to spread the marshmallow cream. It’s sticky and often a challenge to make an even layer.
  • The first time I made this S’mores Cookie Bar recipe, I completely covered the marshmallow cream with cookie dough. But this time, I let some marshmallow peek through. I also sprinkled a few chocolate chips over the top, just to hint at what was below the surface. If you’re looking for stackable bars, you may want to press down on the top before baking to level the surface.

By the way, the whole family gave these bars their seal of approval. Not that I was worried!

Prep Time 30 minutes
Cook Time 40 minutes
Total Time 1 hour 10 minutes
Yield 16 bars


  • 1 stick butter (4 ounces), at room temperature
  • 3/4 cup sugar
  • 1 egg
  • 1 teaspoon vanilla
  • 1 1/3 cups flour
  • 3/4 cup graham cracker crumbs
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt

  • 1 7-ounce jar marshmallow creme
  • 3 tablespoons chocolate chips, optional


  1. Heat oven to 350°. Line 8 inch pan with nonstick foil or regular foil sprayed with cooking spray.
  2. Beat butter and sugar in large bowl until fluffy. Add egg and vanilla; beat well. Stir in flour, graham cracker crumbs, baking powder and salt. Mix until blended. Press half of dough into prepared pan.

Sprinkle with a few tablespoons of chocolate chips if desired.
  4. Bake 35-40 minutes or until lightly browned. Cool completely, then remove from pan using foil and cut to serve.

Love the oooey-goooey stuff what I see bloggers posting, but I don’t want to overdose on too rich of a dessert. Your son Nick is certainly spoiled by his mom…but why shouldn’t he be?

    • Hi, Maitha, I have never frozen these but I think they’d be OK. I’d guess that the marshmallow creme could get a little sticky after defrosting, but it’s definitely worth a try. Let me know how it goes and I can make a note in the recipe. Have a great weekend!
