These S’mores Bars are layered with all the components of classic s’mores; they’re a decadent treat you can eat all year long!

Why You Must Make these Bars

I rebaked and photographed this yummy chocolate and marshmallow dessert recipe this summer after 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.

  • These are a fun dessert for summer picnics and parties! And even to celebrate impending marriages. 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.
  • They have all the s’mores components but can be picked up and eaten or plated to eat with a fork. Plus, I like them MORE than the traditional s’mores.

Ingredient Notes

  • Kitchen Staples – Sugar, Flour, Salt
  •  Butter – at room temperature
  •  Egg – at room temperature
  •  Vanilla – Make sure it’s real vanilla extract, not artificially flavored
  • Graham Cracker Crumbs – From a box or grind crumbs in your food processor using graham crackers.
  • Baking Powder – Note that baking powder most often expires before you use it all. Check the expiration date and replace it as needed. To test its freshness, you can also put a spoonful into a cup of very hot water. If it bubbles vigorously, it’s still active.
  • Milk Chocolate Hershey Bars
  •  5 standard-sized Hershey bars
  •  Jar of Marshmallow Creme
  •  Chocolate Chips – An optional addition you can press into the top of the cookie dough before baking.

How to Make

Expert Tips

  • 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.
  • PRO Tip: 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!
