Because these make so many bars, they are perfect for kids parties and teacher appreciation events as well. Be sure to let these cool completely before cutting. Because they are a sticky bar, they will be much easier to cut into squares when they are well chilled.

How to Make S’Mores Cookie Bars:

Preheat oven to 350 degrees. Line a baking sheet, like this Nordic Ware Commercial Baker’s Half Sheet with parchment paper and spray with cooking spray. Set aside.

First, cream together the butter, sugar, eggs, and vanilla. This can be done in a stand up mixer, or using hand mixer. Next, add in the flour, baking powder, and salt and stir well to combine. Fold in the chocolate chips and marshmallows.

Spread the mixture on to the greased parchment-lined baking sheet and press down using a rubber spatula or damp hands. Next, sprinkle on the crushed graham crackers and gently press to adhere. Bake for 25-30 minutes. Let cool completely before cutting.

Enjoy!
