S’mores Cookie Bars
Marshmallow fluff is something I have never eaten. I don’t know if it’s because I grew up in the Midwest or what… This recipe called for marshmallow fluff so I was excited to be able to check this fluff out and see what all the buzz is about. Marshmallow fluff is interesting. Since I had to use the entire jar for the bars, I didn’t get a chance to try a fluffer-nutter sandwich.
My sister B and I agreed that the proportions seemed a bit off on these bars. The chocolate was thick and seemed to overpower the other flavors in a classic S’mores. I think next time I would use regular Hershey’s bars instead of the king-sized ones which are pretty hefty.
S'mores Cookie Bars
Yield: ~16 bars
Ingredients:
1/2 cup butter, room temperature
1/4 cup brown sugar
1/2 cup sugar
1 large egg
1 tsp vanilla extract
1 1/3 cups all purpose flour
3/4 cup graham cracker crumbs
1 tsp baking powder
1/4 tsp salt
2 king-sized milk chocolate bars (e.g. Hershey’s)
1 1/2 cups marshmallow creme/fluff (not melted marshmallows)
Directions:
Preheat oven to 350°F. Grease an 8-inch square baking pan.
In a large bowl, cream together butter and sugar until light. Beat in egg and vanilla. In a small bowl, whisk together flour, graham cracker crumbs, baking powder and salt. Add to butter mixture and mix at a low speed until combined.
Divide dough in half and press half of dough into an even layer on the bottom of the prepared pan. Place chocolate bars over dough. 2 king-sized Hershey’s bars should fit perfectly side by side, but break the chocolate (if necessary) to get it to fit in a single layer no more than 1/4 inch thick. Spread chocolate with marshmallow creme or fluff. Place remaining dough in a single layer on top of the fluff.
Bake for 30 to 35 minutes, until lightly browned. Cool completely before cutting into bars.

Wow, these look amazing!
These are amazing! And they’re very chocolatey. Definitely need a glass of milk with them 🙂
Whoa! Those look insanely decadent and delicious!
Hi Jan. These Orio Crunch Brownies look delicious and I would like to try an make them. Being in Australia the recipe needs some clarification for me. How much butter is in a stick? We get butter in 1kg and 500 gm packs… Thanks so much. Just found your blog today and oh! oh!, everything looks so nice. I would like to leave my email address for you: jong2505@hotmail.com
Thanks ever so much…

These look so great! Can I eliminate the instant coffee or is it essential to the taste? I am making these for my 3-year-old niece’s birthday party, and she LOVES chocolate, but I don’t think she should have something with coffee in it. What are your thoughts?
Sarah – The coffe in the brownies is there to enhance the flavor of the chocolate. It is not necessary, you could definitely take it out without any issues. I hope you enjoy the brownies!
Sorry to be a pest with questions, but what kind of pan is the size you mentioned? I did a search online and I got two results – a jelly roll pan and also a much deeper roasting pan. The brownies in your photos look thick but I’m not sure if I need to pick up a new pan. Thanks for all of your help!!! 🙂
Sarah – Sorry for not getting back to you sooner. The pan I used is 11x17x1. So it’s not very deep. I always call it a jelly roll pan. Hope that helps!
