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


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)


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.

    Like I said, it’s a multi-step process, so starting part of it tonight might be a good idea. If you make them, I definitely want one. These were so good.

    Definitely give it a shot. They take some time, but it’s SO worth it.

    I’ve been wanting to make these for quite a while as well. My mother-in-law LOVES cookie dough and her birthday is coming up. From all the versions I’ve seen floating around on the internet, I really like yours since you have the LOTS of cookie dough in the middle of your cupcakes. So, you baked the cupcakes with the frozen cookie dough inside? No problems with it baking up? I’m definitely trying this!

    Yep, just dropped the dough into the cupcake batter before baking it. The cupcakes did rise up quite a bit and then sank back down as they cooled. I was a little concerned I had underbaked them, but they were delicious. Definitely let me know how they turn out for you if you make them.

    I want, no NEED, to make these. Does it matter what size your cookie scoop is? Mine is a medium size with about 1.5 tbsp volume. Want to make sure it won’t be too much that it prevents the cupcake from baking up (because honestly, it’s not possible for it to be too much cookie dough).

    I’m honestly not sure what size my cookie scoop is. It doesn’t have any markings on it to give an indication! I think it’s the standard cookie scoop you’d get at the grocery store if that helps at all… I think 1.5 Tbsp sounds about right though.

    I’m already trying to decide what occasion to make them for.

    Well I *might* be making these for Cupcake Camp. So, if you make the trip into Boston for that, you might be able to have one! Too bad they’re not appropriate for Passover.
