S’Mores Cookie Bars

That classic combination of graham crackers, chocolate and marshmallow has been a favorite dessert for many, many years. Unfortunately, many of us (myself included!) can’t fathom the idea of having to go camping in order to take advantage of making s’mores around a campfire.

If you’re hungry for  s’mores, but don’t want to deal with the whole campfire thing, try making these s’mores cookie bars in your kitchen. They combine all the flavors of the chocolate, marshmallow and graham crackers into easy-to-eat bars that you can take to a potluck or just enjoy at home with a glass of milk.

ingredients needed to make s'mores cookie bars

To begin, you’ll want to gather together the following ingredients: graham crackers, white and brown sugars, butter, flour, baking soda, salt, egg, vanilla, chocolate chips, mini marshmallows, and Hershey’s chocolate bars.

You’ll want to pop the marshmallows into the freezer for a few minutes to get firm while you prep the crust and the cookie dough. This helps the marshmallows to retain their shape, rather than melt into the bars when baked.

For the crust, combine the graham cracker crumbs with melted butter and sugar, them press into an even layer in the pan. There’s no need to pre-bake the crust; just set it to the side while you work on the cookie dough.

Mix the two sugars with butter in a large mixing bowl; add the vanilla and egg, then the dry ingredients. Lastly, add in some chocolate chips and marshmallows. The dough will look a little clumpy.

When mixed, spoon the cookie dough on top of the graham cracker crust, and press into an even layer. Sprinkle the remaining marshmallows on top and bake for about 15-20 minutes, until the center is set.

While the cookie bars are baking, break up your Hershey’s bars into smaller pieces and place them into the freezer. When the cookie bars come out of the oven, let them cool for just a few minutes, then place the Hershey’s pieces on top of the bars. The residual heat of the cookie bars will melt the chocolate ever-so-slightly, allowing the Hershey’s name to hold its shape.

After the bars are completely cool, cut them into squares and enjoy!
