These Gooey S’mores Cookie Bars are what summer dreams are made of! They’re insanely delicious and taste just like a s’more, with graham cracker cookie dough layers that sandwich oodles of marshmallow creme and melty milk chocolate.
I love summer time! The kids are home from school, so we get to spend all day together. I like to keep a little schedule with them, just for our sanity. So, in the morning, they have a few chores to complete and some reading to do and then we have a fun activity every afternoon. Whether that’s swimming or just running through the sprinklers or playing hide and seek. The carefree summer days are unbeatable!
Something that’s always on my kids’ summer bucket list is camping in our yard. We always roast s’mores and tell spooky stories as it gets dark. Right now, we have fire restrictions in our area because we are in a severe drought. So we are trying to do our part by playing it totally safe and not building a camp fire in our fire pit.
So, guess what that means? I’ll be making loads of these Gooey S’mores Cookie Bars to get my s’mores fix this summer! Heck, I’ll be making them year-round when making a campfire isn’t an option! My family went wild for these! I knew that I wanted the cookie portion to taste just like graham crackers, so I crushed a bunch of graham crackers and added them to the dough.
Then, I layered about three-fourths of the dough on the bottom, added a whole tub of marshmallow creme (hello amazing!), and sprinkled milk chocolate candy bar pieces generously over that. To finish it off, I added the final one-fourth of the cookie dough on top and baked it to perfection! I love that the marshmallow creme stays gooey and soft! Sometimes marshmallows get a little more tough when baked. So marshmallow creme was the ultimate option!
These bars are absolutely irresistible! I can’t wait for you to make them to see what all this hype is about. 🙂 They live up to that hype! You’ll want to take them to every summer gathering. Everyone will go bonkers for them! Whatever your summer plans are, I hope they include these Gooey S’mores Cookie Bars! When I think of summer, s’mores are the first thing that come to mind. And when I think about s’mores now, my thoughts will immediately be drawn to these S’mores Cookie Bars, because they are that good!
They’re made in an 8″x8″ pan, so you’ll probably want to double them if you’re taking them to a gathering. Trust me, these will disappear in a hurry! The summer always flies by, so I’m really soaking it all in and trying to enjoy every moment with my kiddos before they head back to school. But you can bet I’ll be making tons of s’mores desserts to celebrate this fun season and make it even more memorable!

Gooey S’mores Cookie Bars
Ingredients
- 1 1/2 c. graham cracker crumbs finely crushed
- 1 c. light brown sugar packed
- 3 large eggs
- 1 1/2 tsp. vanilla extract
- 6 Tbsp. butter softened
- 1 1/2 tsp. baking powder
- 1 1/2 c. all-purpose flour
- 1/4 tsp. salt
- 7 oz. container marshmallow creme slightly warmed in the microwave to make it easily spreadable
- 2-3 Hershey Milk Chocolate Candy Bars broken into small sections
Instructions
- Preheat the oven to 350 degrees Fahrenheit.
- Grease an 8"x8" pan, or spray with nonstick baking spray.
- In the bowl of an electric mixer, add graham cracker crumbs, brown sugar, eggs, vanilla, and softened butter and cream together completely, scraping down the sides with a spatula in between.
- In a separate bowl, whisk together baking powder, flour and salt. Add flour mixture to the wet mixture and mix just until combined.
- Press 3/4ths of the cookie dough into the bottom of the prepared pan, reserving the remaining 1/4th for later.
- Spread the slightly warmed marshmallow creme over the cookie dough, then sprinkle evenly with Hershey bar pieces.
- Take small portions of the remainder of the cookie dough at a time, press flat in your palm, then lay on top and try to piece together as best you can. It's ok if the entire thing isn't covered completely. Small areas of marshmallow and chocolate may peek through.
- Bake for approximately 20-22 minutes, or just until set. Remove from oven, allow them to cool mostly, then cut into bars and serve.
