If I had to pick one Summer dessert it would have to be anything with s’mores. And it would be these s’mores cookie bars!

I love the crunchy graham cracker, melted chocolate and toasted, gooey marshmallow. I even used to make gourmet s’mores on the stove!

Heck if you need other inspiration I love my nutella s’mores gelato as well. But I have to say these peanut butter s’mores cookie bars take the cake.

I love s’mores, but sometimes I just don’t want to have to spend all the time sitting around a fire pit to make them. In keeping with tradition I have been thinking of other ways that I can make s’mores to feed the masses.

This got my creative juices flowing and I thought of a s’more bar! I looked in my pantry and didn’t have graham crackers, so I looked at what else I could find and found peanut butter cookie mix.

The cookie mix was perfect because it emulated a graham cracker crust. So that is what I used and they came out phenomenal!

These peanut butter s’mores cookie bars have a rich peanut butter cookie crust, molten chocolate filling and a gooey toasted marshmallow topping.

I like to use dark chocolate, but you can use milk chocolate or even Reese’s peanut butter cups.

You can even change up the crust by doing a brownie crust or chocolate chop cookie crust.

Another fun tip with these s’mores cookie bar recipe is to use a kitchen torch to toast the marshmallows. If you are particular about how toasty your marshmallows get, this is the best trick to have the most control. I like to use this kitchen torch which also works great for my Instant Pot Creme Brulee
