Easy Large Batch Cookie Bars Recipe

If you need to feed a crowd, or are looking for an update to your cookie recipe, this is it! These super tasty bars are moist and gooey from all of the melted marshmallow. Perfect treat for potlucks, parties, or cookie exchanges. Moreover, you can make these in advance and freeze them until you need them.

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 in a Sheet Pan

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.

Firstly, cream together the butter, sugar, eggs, and vanilla. This can be done in a stand up mixer, or using hand mixer. There will be a lot of batter with this recipe, so a stand up mixer is recommended if you have one.

Then, add in the flour, baking powder, and salt. No need to mix ahead in a separate bowl. The dry ingredients can go right in with the wet.

Then, fold in the chocolate chips and marshmallows. Here I use an entire bag of marshmallows and chocolate chips. Remember, this recipe feeds a lot of people!

Finally, spread the mixture on to the greased parchment-lined baking sheet and press down using a rubber spatula or damp hands.

Lastly, sprinkle on the crushed graham crackers and gently press to adhere.

Bake the cookies for about 20-25 minutes. You want the top of the bars to be just a light golden brown. Let the bars cool, then remove with parchment and cut into squares.
