Soft and Gooey S’mores Bars
It’s not summer time without some sort of s’mores dessert. While I love the traditional campfire version, it’s also fun to make variations like these delicious s’mores bars. Add a scoop of homemade ice cream and this bar recipe is the best summer dessert you can enjoy year round!
Ooey gooey s’mores bars are the best parts of my favorite chocolate chip cookie “congo” bar recipe combined with a graham cracker crust, chewy center and marshmallow top. Add some milk chocolate candy bar and it’s the most delicious s’mores bars!
How to Make S’mores Bars
- Make crust. Combine melted butter and graham cracker crumbs in a small bowl with a fork. Press crust down into a greased 9×13″ baking dish and set aside.
- Cream dough. In a large bowl, cream together butter and sugar. Add in eggs and vanilla and stir until combined. In a separate bowl, mix the baking powder and salt with 1 cup of flour. Then pour flour mixture into the butter mixture and stir in the rest of the flour. Fold in chocolate chips and marshmallows.
- Assemble s’mores bar recipe. Press dough into pan with a spatula or flour on your hands. The dough goes right on top of the crust. Then add the candy bar, graham cracker and marshmallows on top.
- Bake. Bake at 325°F for 30-35 minutes, or until lightly browned. Oven temps will vary. Test with a toothpick. The dough should be soft in the center.
Quick Tips
- Line your baking dish with foil: It helps with easy removal and requires less clean up.
- Add extra toppings: Don’t forget to top your dough with extra marshmallows, candy pieces and graham crackers. It adds AMAZING flavor.
- Let cool before cutting: The bars continue to set as they cool and will be easier to cut.
- Store in an airtight container: Keep at room temp in an airtight container for about 3 days (or in the fridge for about 5 days).
- Wrap and freeze: You can also freeze them. Let cool, then wrap in foil and place in airtight container/bag. Store in freezer for 2-3 months.

I’ve made these twice now and they were all big hit both times. My brother had me make a pan for his family. I’ll be making them again for sure. There even better heated up in the microwave for a couple of seconds . I’ve added extra hershey bar’s to mine. So good
I’m so happy that they were a hit with your family! Extra Hershey’s is always a good idea :)
I was scared from some of the other reviews so I packed the dough in pretty good. Bottom stayed on pretty good; they were delicious, but a little hard around the edges. Next time I won’t pack it down so much.
Excellent recipe!!! They were delicious!!!
I’m so glad you enjoyed them! :)
Made this last night and they came out perfectly!

Light brown sugar.
Hi jamielyn! If I make this recipe in an 8×8 will it be insanely thick?
Hi Liz! Yes, it will definitely be thick. You might have a hard time getting it to cook all the way through without the edges burning!
Just made this and they’re so awesome I recommend you make them
I’m so glad you enjoyed them!!
Do I use salted or unsalted butter?
I use unsalted!
Great recipe!!!
Any suggestions for replacing sugar/flour with almond flour/splenda?
Hi Eve! I’m sorry I’m not too familiar with those substitutes to give you a good answer. Please let us know if you give it a try!
I substitute gf 1:1 flour and gf graham crackers and they always turn out great
This is soo gooey and good. You could eat the whole pan with a carton of milk. Will make again.
