I love making magic bar variations! Because magic bars are actually magical.

But you guys. I forgot how amazing these S’mores Magic Cookie Bars were until I recently decided they needed a video and to be re-photographed.

What is the Magic Bar?

Traditionally, magic cookie bars are a seven layer bars with graham crackers, chocolate chips, nuts, coconut, and sweetened condensed milk. There is for sure a reason why these dessert bars are called magical. Because of the make up of the original recipe, it’s easy to come up with a ton of variations on these bars.

I love throwing a thicker layer in the middle of my magic bar recipes. Usually a brownie or cookie layer gives a little something extra. In these S’mores Magic Cookie Bars, I went with a sugar cookie layer. It makes for a truly decadent amazing dessert.

These are rich and best enjoyed when cut into small bites. And then if you are me, go back to the pan over and over and over again until you beg your husband to take the whole pan to work.

Tips for Making these Magic Bars

You are basically making cookies from scratch to shove in the middle of these magic bars, so these tips might come in handy.

  1. Room temperature butter means that you can dent the butter easily with your finger but can’t push it all the way through. To bring your butter to room temperature fast, cut it into one inch pieces and leave it on the counter for a half hour.
  2. Measure your flour by scooping it into the measuring cup and then leveling off. This will prevent the flour from packing (if you scoop right from the container), and ending up with a recipe with too much flour.
  3. When it comes to the baking time, keep an eye on them. Oven temperatures can vary, making a big difference in how long these need. Mine baked close to 27 minutes, but from 22 minutes on, I was checking on them and waiting to get a nice golden edge around them.

S’mores Magic Bars

Serves: 24 bars
(tap # to scale)
Prep: 25 minutes
Cook: 27 minutes
Total: 52 minutes
These S’mores Magic Cookie Bars will disappear almost as fast as you can make them, they are irresistible! Made up of absolutely amazing layers of graham cracker, sugar cookie, chocolate, marshmallows, and topped with sweetened condensed milk, there is a LOT to love about these!

Ingredients

Graham Cracker Layer

  • 9 graham cracker sheets approximately 5.4 oz worth, crushed
  • 6 TBSPs of unsalted butter melted
  • 2 TBSPs granulated sugar

Cookie Layer

  • 1 1/4 cup all purpose flour scooped and leveled
  • 1/4 tsp salt
  • 1/4 tsp baking powder
  • 3/4 cup granulated sugar
  • 1/2 cup unsalted butter room temperature
  • 1 tsp vanilla extract
  • 1 large egg
  • 1 cup milk chocolate chips
  • 1 cup mini marshmallows
  • 3/4 cup sweetened condensed milk

Instructions

  • Preheat your oven to 350 degrees. Spray a 9 by 13 inch pan with cooking spray well and set aside.
  • In a large bowl, mix together the graham crackers, the 6 TBSPs of butter (melted) and the 2 TBSPs of sugar. Press into the bottom of the pan.
  • In a different bowl, mix together 1 1/4 cup flour, 1/4 tsp salt, and 1/4 tsp baking powder, set aside.
  • Beat together 3/4 cup of granulated sugar and 1/2 cup unsalted butter until creamy, about two minutes. Add in the egg and then the vanilla until just combined. Slowly add in the flour mixture until it is fully combined.
  • Very carefully spread the cookie dough mixture on top of the graham cracker crust. The easiest way to do this is to take small amounts, flatten it in your hands, and set it on the crust. You may not be able to entirely cover the graham cracker crust, that’s okay.
  • Evenly spread the mini marshmallows and the chocolate chips over the top of the cookie dough. Then evenly pour the sweetened condensed milk over the top.
  • Bake for 22 to 27 minutes or until the edges are golden brown. (Mine required closer to 27 minutes.)
  • Let the bars cool overnight before cutting. Or just take a fork and go for it.

    I made these for a funeral and they were delicious! And a HUGE hit. But i’m Wondering if they can be frozen? I’m doing all the desserts for a wedding and they’ve requested these. Just trying to get a head of the game.

    • Lisa Longley says

      I haven’t tried freezing them, if you do, let me know how it turns out!

  3. Becky says

    Hello! I made these bars last night. I baked them for 25 minutes. I left them to cool on the counter overnight. When I cut them this morning, the cookie part didn’t seem to be done. Is that the way they are supposed to be? I am supposed to take these to work today but I don’t want to if they aren’t done. Thank you!

    • Lisa Longley says

      Becky, I’m sorry the cookie part wasn’t done. That layer definitely is on the softer side, but it shouldn’t seem raw. Without being there its hard for me to know where things might have gone wrong. I will say that oven temperatures do vary, so that could be to blame.

    I don’t normally leave a comment but these were just too good not to! I have tried different smores bar recipes and sometimes theyre dry & crumbly or dont taste much like a smore, these checked every box!! Gooey marshmallows, melted chocolate & graham crackers. Maybe I have an extreme sweet tooth cuz in the recipe it said: very rich take small pieces :) um no take a giant piece so you dont have to go back 3 times they’re just that amazing!!

    • Lisa Longley says

      Erma, I got this comment at the end of the **worst** day, and it totally changed my mood. Thank you so much for taking the time to come back and let me know! It seriously made my day.

    WOW!!!!!!! I’m really having to use some serious will power not to go back and eat the entire pan right now. These are amazing! My husband, who doesn’t usually get super excited about food, LOVED these. Mmmmmm!!! I cooled them quickly by popping them in the freezer for 30 minutes and then thawing a few minutes on the counter before cutting. Worked great!

    • Lisa Longley says

      I’m so happy you liked them Andrea!

    Has anyone tried to do the sugar cookie layer on the bottom then the graham cracker? I was thinking maybe the cookie would be a good base and spread easier than on top of the graham cracker :)

  7. Suzy v says

    I just took mine out of the oven, I’m not sure if they turned out right, bc the marshmallows are crunchy and not gooey? I took them out of the oven when it said to, thought at first Mabey I should have poured the condensed milk over the top but reread and I did it correct. I’ve never had them before so not sure if they will get soft and gooey after sitting overnight? But even if they don’t, i wont be mad, bc all things s’mores are yummy!! Thanks for the recipe!

    • Lisa Longley says

      The sweetened condensed does get poured over the marshmallow layer before it goes in the oven. I hope they turned out okay!

    I made these last week for the first time and my family were interested, but generally ignored them overnight while they cooled. Then they tasted them. OMG, I won’t tell you how fast the entire batch disappeared. Fast forward to today. They asked to make them (and even agreed to help!). When the timer went off they came bounding down the stairs. Think this batch may less even fewer days! This is a keeper.

      This is the greatest comment! Thank you so much for coming back to let me know, Amy!
