These S’mores Blondies are chewy, gooey, and made for summertime. The buttery brown sugar cookie base is loaded with graham cracker crumbs, milk chocolate chips, and melty marshmallows. I add more of the s’mores mix-ins on top for a toasty marshmallow morsel in every bite. Forget the campfire and stay cool inside making these sweet treats.

I’m not much of an outdoorsy girl myself so I would take these any day over a traditional, sticky s’more by the campfire. Not only do these blondies have all the flavors of a s’more but they can be whipped up in under an hour. What’s not to love about a versatile cookie bar that is easy to make and quicker than scooping cookie dough?! If you’re feeling adventurous, give them a try with brown butter like my Brown Butter Blondie Bars.

Ingredients

‍

This recipe does not require anything fancy or fussy. Just your basic cookie recipe ingredients plus the s’mores staples.

• Graham Cracker Crumbs: You can buy these already ground up (in the baking aisle) or crush the graham crackers yourself. I put them in a small ziploc bag and smash them with a meat mallet or the bottom of a drinking glass. A mini chopper or food processor works too!
  
  
• Milk Chocolate Chips: I used Ghiradelli chocolate chips. Guittard also makes a nice size milk chocolate chip that’s a little bit bigger than most. Even a chopped-up Hershey’s bar would work!
  
  
• Marshmallows: I use mini marshmallows so they get disbursed throughout the batter. Scatter some on top of the blondies for perfectly toasted melty morsels on top.

How to Make S’mores Blondies

‍

1. Make the blondie base. The blondie base is just like a classic cookie base but uses melted butter so it all comes together quickly in one bowl. Brown sugar for the chewiness and a little baking powder to give it a slightly cakey texture on the edges.
   
   
2. Add in the s’mores mix-ins. The graham cracker crumbs get folded in with the other dry ingredients followed by the milk chocolate chips and mini marshmallows.
   
   
3. Bake the blondies. Bake the blondies partially until the top is just set, about 10 minutes. I let the bars bake a little first before adding the toppings so the graham cracker pieces and marshmallows don’t get too dark.
   
   
4. Add s’mores toppings. Remove the pan from the oven and sprinkle on as many graham cracker pieces, chocolate chips, and marshmallows as your heart desires. I like leaving a few pockets where the blondies can still peek through but it’s totally up to you!
   
   

‍

5. Finish baking the blondies. The blondies will need about another 15 minutes to bake until they are fully set and the marshmallows are perfectly toasty. Let them cool, then cut and enjoy!

What Does a Blondie Taste Like?

‍

Blondies taste very similar to the cookie dough base of a chocolate chip cookie but they’re baked in a square or rectangle pan, like a brownie. They are soft and buttery, slightly gooey in the middle, and chewy around the edges. I make my blondies with melted butter, which gives them more of a dense, gooey texture rather than light and fluffy. Just like cookies, the ideas you can come up with to mix into your blondies are endless!
