    Cookie Butter has always been a true love of mine. If you have not tried Biscoff Spread or Trader Joes Cookie Butter you are SERIOUSLY missing out. It is one of my all-time favorites. Whether you are dipping apples in it, baking cookies with it (Cookie butter Sea Salt CC Cookies or my Cookie Butter Oatmeal Scotchies), spreading it on a waffle or stuffing it in these smores bars. There is nothing quite like it.

    Cheesecake and desserts with fresh whipped cream are my all time favorite but during these hot summer months years in Southern California, they just don't work for parties outside.

    So if I can't have cream then I'll take cookie butter.

    These were sooo good. Out of the oven and chilled straight out of the fridge. Not gonna lie, I ate half the pan myself. It was one of those let me straighten the line kind of pans, you know the kind where you slice a little bit off so then you have to end up slicing a little more off to even out the line in hopes that no one will notice.

    Cookie Butter Smore's Bar with a bie taken out and more bars in background

    📖 How do you make Cookie Butter S'mores Bars?

    Start off with preheating your oven and lining a 9-inch square pan (this one is my fave with the removable bottom) with foil, so the foil overhangs (this makes it easier to remove from the pan once baked.)

    In a large clear bowl add melted butter and brown sugar, whisking to combine. Add in egg and vanilla extract, then whisk again until fully combined.

    Then add the flour, graham cracker crumbs, baking soda, and salt. Mix until just combined.

    Then the best part! Cadbury's Dairy Milk, yum!

    💬 How do you layer everything?

    Press half of the batter into the prepared pan. Drop about 9 dollops of Cookie Butter on top of batter and using a knife swirl the Cookie Butter into the batter.

    Then place the chocolate on top of the batter, you want an even layer of chocolate, break the bar up to fit the nooks and crannies. Place all of the marshmallow fluff on top of chocolate in an even layer.

    Dollop the remaining Cookie Butter on top and swirl that into the marshmallow fluff.

    Take the remaining batter and press it between your hands into a disc, I think this makes it easier to make sure all of the marshmallows is covered.

    Bake for 25-30 minutes until. Let cool completely or else you will have a gooey mess!

    If you are going to eat the pan all to yourself, by all means, dig in a few minutes after they are out of the oven but if you are serving them to guests or you want them to look nice let them cool completely in the pan.
