Baked S’mores Cookie Bars

NO camp fire needed to make these

This is just as delicious & marshmallowy- gooey as the original recipe this is inspired by

I made a rather large batch of these S’mores Cookie Bars for 60 people just the other day. This is one of those desserts I knew my tray would come back without any leftovers.

So if we wanted some, I would need to make a smaller pan for my family while I made this big batch.

My son & I really like this dessert and probably rank this as one of our top favorites!

In fact, my son likes this dessert so much, this is what he asked for as his birthday ‘cake’ this year.

No cake for their birthdays

You see, neither of my children likes to eat cake and I noticed that with our son when he was just a year old.

So if my kids didn’t like to eat cake on their birthday (or would just eat the icing) why would I make them something on their special day they wouldn’t eat?

I just stopped making cake for my children’s birthdays and my son had a lot to do with it!

Please no cake mommy!

For my son’s first birthday I scheduled a photo shoot with a photographer at her studio to celebrate this momentous day.

We discussed a shoot with balloons, fun props & cute things to do. And we agreed that I would bring a smash cake for my son to play with.

What’s a smash cake? It’s just a small cake for the birthday boy or girl to get into with their hands to eat and get messy.

This was the first time my child would have cake and I was so excited about it.

But this did NOT go as planned.

My sweet baby boy is shy and while he did well at the beginning of the shoot, it went south quickly when the smash cake came out.

Literally as soon as we brought the smash cake to my son, he didn’t like it.

He wouldn’t touch the cake or even go to it. So I scooped some of the icing with my finger and brought it to his mouth but he pushed it away.

He started to get upset-so I thought I will get into his cake, and show him I wanted him to play with it and eat it.

I hoped he would want to do it, too. NOPE!

My birthday boy started to shed tears and eventually whaled until I cleaned up and got rid of the cake.

I chucked the smash cake and cheered up my boy.

On the bright side, the photographer was able to capture some sweet moments before his tears and a few afterwards that I’ve kept.

I still can’t figure out why he was so upset when the smash cake came into the scene.

My son had been photographed professionally during his first year marking every holiday at this studio so looking back I don’t believe it was this shoot.

For a couple birthdays after, I noticed he would not eat any birthday cake. Even at other parties we went to, he still wouldn’t eat cake.

Sometimes he wouldn’t even eat the icing and I thought every kid liked that!

He told me he didn’t like cake

One day when my son was older (and on a random day not his birthday) he told me that he didn’t like any kind of cake.

Could it be that he didn’t like cake when he was only 12 months old? Who really knows?

But one thing I do know-it is rare for either of my children to eat cake or cupcakes.

So for my children’s special day, I am happy to make something other than the traditional birthday cake.

They do like to eat sweets!

Don’t misunderstand-my kids LOVE sweets-they love sugary candy and chocolates.

My son does love some cakes-pound cake and cheesecake. Oh and pie-he loves pie! And his favorite is key lime pie.

If you think about  alternatives for birthday cake, it is actually pretty easy to come up with something else.

Some years we’ve had pie for his birthday or a big chocolate chip cookie ‘cake’ or a HUGE rice krispy treat ‘cake’-sometimes decorated with tons of candy on it.

No matter what they want, I want to make a ‘cake’ they will love and want to eat.

And the Baked S’mores Cookie Bar was easy to make for my son on his special day this year. I just tripled the recipe to make a large pan for his party.

The Baked S’mores Cookie Bars are delicious and messy just like the camp fire version.

I love to eat these when it’s warm and gooey with a tall glass of cold milk. And I love it a day old & cold with my morning coffee.

I especially love that I don’t need a camp fire to make this dessert.

  • • 1 stick unsalted butter room temp
  • • ¾ cup brown sugar
  • • 1 egg or ¼ cup egg white product room temp
  • • 1 tsp vanilla
  • • 1 cup all purpose flour
  • • 1 cup crushed honey graham cracker (about 1 sleeve of crackers or 9)
  • • ½ tsp kosher salt
  • • ½ tsp baking powder
  • • 1 bag semi-sweet chocolate chips
  • • 1 large jar (or 2 small jars) marshmallow fluff (NOT marshmallows)


  1. Line 8x8 pan with parchment and preheat oven 350 See Tip below
  2. In stand or hand held mixer, beat butter and sugar until pale and fluffy about 2-5 minutes. Add egg and mix well- scrape bowl as needed. Add vanilla and mix well
  3. In separate bowl, place flour, graham crackers, salt and baking powder mix with fork. Add dry mixture to wet in 3 parts. Any graham cracker pieces that weren’t crushed enough will get crushed here
  4. Divide dough equally and spread one half of dough in the bottom of pan. Heavily Layer semisweet chocolate chips so dough is completely covered.
  5. (Pull marshmallow fluff out of hot water bath) Spread marshmallow fluff with offset spatula (if you have one). If you allowed to softened in hot water bath it spreads easier (see tip below).
  6. Finish with the top layer of dough which can be hard to "spread" on. You can either roll the dough and transfer on top of marshmallow layer or lay flattened pieces on top and bring them together. It's okay if marshmallow fluff peeks out!
  7. *TIP*In a large bowl fill with hot tap water and place unopened jars of marshmallow fluff. Allow to sit in bath while making cookie dough so it softens and becomes easier to spread.
