Instructions
- Step 1: Combine browned butter, sugar, and brown sugar with vanilla, egg and egg yolk.
- Step 2: Add flour and baking powder to wet ingredients.
- Step 3: Mix chocolate chips in dough.
- Step 4: Add 3/4 of the dough to the pan and spread out marshmallow fluff, then dollop on the remaining dough. Bake in a preheated oven for about 35 minutes.
Hint: Make sure to leave the parchment paper slightly longer than the pan so you can easily remove the bars after they’re done baking!
Variations
S’mores is definitely my favorite combination with these cookie bars, but the options are endless!
- Chocolate Chip – sometimes plain and simple is the way to go! Leave out the marshmallows and enjoy these chocolate chip cookie bars!
- Peanut Butter – add a few dollops of peanut butter to the top of these to get a delicious peanut butter swirl!
- White Chocolate Raspberry – swap out the dark chocolate for white chocolate and add in freeze-dried raspberries for a fruity spin on these cookie bars!
Equipment
The only thing these easy s’mores bars require in a square pan to bake them in! You can also use a 9×13 rectangular dish, but the bars will be on the thinner side! Using a square pan creates thick and chewy bites!
Here is the link to the pan I use!
Storage
Store these S’mores Bars in an airtight container in the pantry for about 5-6 days! If you were going to freeze them, I recommend baking them first, allow to cool completely before wrapping them individually and then storing in an airtight container for about 3 months.
While you can technically freeze these, I don’t recommend it with this recipe because the marshmallow fluff can lose its texture and consistency after freezing.

Top tip
To get clean lines when you’re cutting these bars, let them cool for about 10-15 minutes before cutting! If you try to cut them while they’re still hot, it could turn into some messy slices!
FAQ
Absolutely! You might have to lower the baking time, since these bars will be slightly thinner than if you use a square pan!

Currently have these in the oven. However, the dough was so crumbly. You have one part where it says 2 eggs and another where it says 1 egg and one egg yolk. I did the latter.
Oh no! I’m sorry that happened! The recipe calls for 1 egg and 1 egg yolk, I went back and updated the section that says 2 eggs. I believe I wrote that so people would know you need to have two eggs at home for this recipe, even if you only use the yolk from one of them! But I updated that to make it more clear for everyone!
Mine also came out crumbly! 2 cups of flour seems like an awful lot… I’m thinking maybe it’s wrong?
Oh no! I’m sorry about that! Let me fix the recipe for you!
Love the gooey marshmallow in these!!
