Key Ingredients
- Butter - we use unsalted butter. If you want to use salted butter, you can reduce the salt in the recipe by ¼ teaspoon.
- Sugars - you will need a combination of both granulated sugar and brown sugar which keeps the flavors on point and the texture nice and chewy.
- Baking Powder - this helps to give the bars a little lift.
- Graham Crackers - these are crushed and added to the cookie dough.
- Chocolate Chips - you can use mini or regular size.
- Marshmallows - we use mini marshmallows. If you prefer Marshmallow Fluff, you can see our directions below for how to make these S’mores Cookie Bars with that instead.
- Hershey’s Chocolate Bars - this is classic. You can always use a different brand of milk chocolate, or else substitute extra chocolate chips. It’s a good idea to place the broken apart chocolate pieces in the freezer for a few minutes before putting them on top of the hot cookie bar pan so that they hold their shape.
How To Make S’more Bars
- Mix the cookie dough. Cream together the butter and sugars until light and fluffy. Add in the vanilla and salt and mix to combine, then slowly add the eggs, mixing on low to combine. In a separate bowl, whisk together the baking powder and flour, and add into the butter mixture, mixing on low just until combined. Once your dough is almost completely combined, add the chocolate chips and crushed graham crackers and gently fold in by hand.
- Press into a baking sheet. Remove dough from the bowl and press into the greased cookie sheet as evenly as possible.
- Bake. Bake in a preheated oven for about 20 minutes, or until the edges are golden brown and the large cookie has begun to set. Remove from the oven and spread the mini marshmallows evenly over the top, then return to the oven for about 10 more minutes, until the marshmallows begin to melt and brown slightly.
- Cool. Remove from the oven and let cool for about 1 minute, then place the frozen Hershey's Chocolate pieces evenly over the top. Cool completely before cutting into bars. Enjoy!
