National S’mores Day is also coming up on August 10th, so be sure to hold on to this cookie recipe.
What’s a S’more?
I’m sure most of you are familiar with s’mores, but just in case you aren’t…
You typically roast a marshmallow on a long stick over a campfire, then put it in between two graham crackers and chocolate. A fun summer treat!
How to make S’mores Bars:
No fire needed for this cookie version!
First preheat your oven and lightly grease a 13×9-inch baking dish.
Then in a mixing bowl, mix together the flour, graham cracker crumbs, baking soda, and salt.
I like to put the graham crackers in a food processor and process for just a few seconds to get the crumbs. You could also put the crackers in a resealable bag and using a rolling pin, roll over the crackers back and forth until crumbs.
Next, in another bowl, mix together the butter and sugars with an electric mixer until light and fluffy. Mix in the egg and vanilla until well combined, then mix in the flour mixture.
Spread about half of the cookie dough on the bottom of the 13×9-inch baking dish. Butter or grease your hands a little if they stick to the dough too much. You can use your fingers or back of a fork to help form a nice even layer.
Unwrap the chocolate bars and place them in a single layer on top of the cookie. Break the bars into pieces to fit around the edge if necessary. I used the regular Hershey’s chocolate bars (not the king size).
Spread the marshmallow fluff on top of the chocolate bars. Do NOT use regular marshmallows. They will melt.
Lastly, you’ll want to cover the marshmallow fluff with the remaining cookie dough. You have a couple of choices. You can take some of the cookie dough, flatten it in your hand then place on top of the marshmallow fluff in pieces.
OR my new preferred way, is to roll out the remaining dough on a piece of parchment paper or silicone mat to form a 13×9 inch rectangle the same size as your pan. Flip it over on top of the marshmallow fluff then peel off the parchment paper or silicone mat. With your fingers fix any holes, but don’t worry if there are some open spots!
Bake the S’mores Bars until they are golden brown around the edges.
Yes, I know there are many s’more bar recipes out there. The ones I have seen are all made in small pans. A small pan is not going to cut it. Like I mentioned, I made these in a 13×9-inch pan and trust me, go with the 13×9 inch pan version!
These s’more cookies will go FAST! If you want to spruce these cookies up a bit you could add all sorts of things like nuts, peanut butter, bananas, toffee bits, coconut, etc. into the middle
Some recipes call for the king size chocolate bars, but like I mentioned above, I used regular sized chocolate bars. Unfortunately, you do need quite a few to fill a 13×9-inch pan (like 9 chocolate bars…) so look for a multi-pack in the candy section of your grocery store to save some money.
You could also just use chocolate chips if you want or melt the chocolate chips, spread on wax paper, cool until hard, and use that instead of the chocolate bars. If you do just use chocolate chips, it may take some extra effort spreading the marshmallow fluff on top since you won’t have a flat surface like the bars.
Be sure to cool the S’mores Bars so you can cut into squares. The chocolate and marshmallow may be a little ooey gooey while warm. I personally love that, but if you don’t let them cool completely first. I
