Smookie is the biggest crowd-pleaser, these addictively delicious bars are made of a thick and fluffy marshmallow layered between soft and chewy Grahm cracker chocolate chip cookies.

The combination of chocolate and marshmallow is so popular for a reason, and it can come in many versions like S’mores Pies, and S’mores Hamentashen. You can even take the extra milk with this S’mores Babka, and Hot Cocoa Brownies.

Smookie needs no explaining, it might look all fancy but truth be told that this is nothing more than a bar, much like these White Chocolate Pecan Blondies, these Matcha Brownies, and these Biscoff Brownies. It would be wise to just stop, take a moment, slowly breathe in and out, and let it all sink in.

You’re good? GREAT!

Here is some more great news: these bars are super easy to make, and even more fun to eat. You see like any good old s’more, there are two ways to enjoy this treat.

The “tidy” way – eat it after slicing. Just pick up a slice and enjoy.

The Messy (hence the FUN) way – place in a 500F preheated oven and bake for 3-5 minutes. I would use a spoon and eat straight out of the pan. (please note that the marshmallow will melt and drizzle out so reheat the smookie in a pan.)

For the cookie:

What ingredients are in this Smoke recipe:

  • Bread flour, the bread flour has a high recent age of gluten which absorbs water and provides the cookie a chewy texture. If you do not have bread flour at hand, use regular all-purpose flour.
  • Graham crackers crumbs
  • Unsalted butter at room temperature
  • Salt
  • Baking soda
  • Light brown sugar, provides flavor and contributes to the chewy texture of the cookie.
  • Granulated sugar
  • Egg, at room temperature
  • Chocolate chips, the recipe calls for semi-sweet, but you can use milk chocolate chips or any kind you like.

For the Marshmallow:

  • Granulated sugar
  • Light corn syrup, this syrup provides volume and the elasticity needed for the marshmallow. If you prefer, use honey instead but please know, it will change the flavor.
  • Water
  • Salt
  • Gelatin powder
  • Vanilla extract

How to make these Smookie bars?

There are three parts in making these parts: making the cookies, making the marshmallow and assembling.

Since the marshmallow sets daily fast, it is important to plan ahead and start baking the cookies. You can do that same day or even a day or two in advance.

Baking the cookies:

Baking the cookie dough is an easy and simple process as baking chocolate chip cookies but with the exception of scooping the dough.

We start by mixing the butter and sugar together until well combined, then mixing in the egg and vanilla extract. The next step is to incorporate the dry ingredients into the mixture followed by the chocolate chips.

In this recipe, we divide the dough into 2 parts: 2/3 of the dough will be baked in 8″x8″ square pan, and the remaining 1/3 part will be baked in a separate 8″x8″ pan (or a mold).

Once the dough is baked, allow it to cool while you make the marshmallow.

Making the Marshmallow:

To make the marshmallow we will need to use a candy thermometer. Firstly, mix the gelatin with 1/2 the amount of the water in a bowl of a standing mixer and allow the elating to bloom and hydrate. Next, cook the sugar, corn syrup, salt, and remaining water over the stove until the temperature reaches 240C. Pour the sugar syrup over the gelating mixture and beat using the whisk attachment on low gradually increasing to high speed. You will notice that just as in the images below, the mixture will gradually change it color from transparent to white and its texture from liquid and viscous to thick and elastic. The process can take anything from 5-10 minutes depending on the speed of the mixer you are using.


This is the fun part. But before we start, make sure to great the spatula you are using otherwise the marshmallow will stick to the spatula leaving you with a marshmallow mess.

Pour the marshmallow on top of the bigger piece of cookie and allow it to set. Once set, break the second piece of cookie and lay the pieces on top of the marshmallow. And last, remove from the pan, slice, and enjoy!

Storing the Smookie bars:

The bars should be stored at room temperature for up to 5 days.

Here are a few more ideas:

  • Feel free to add any color of food coloring to the marshmallow. (add it right after you drizzle the hot syrup in the mixing bowl.
  • For a marble effect, add a few drops of food coloring right after you layered the marshmallow on the cookie, and using a toothpick, create the marble effect.

    I would like to try these GF – I have no equivalent of bread flour – wondering how essential that is to the recipe.

    1. Dikla

      Bread flour is what makes the cookie chewy. I have yet to try it GF but I know that GF flour out there are really good and the cookie should come out just fine!

  2. Dikla

    Hi there! I’m trying out this recipe today but as I’ve been going through it, I’ve noticed some typos and missing ingredients.

    Example, in the instructions you say to add the vanilla to the cookie dough, but in the ingredients list you do not include it for the cookies. Just the marshmallow.

    It’s also unclear how much gelatin to use. So I’m opting to do a different mallow recipe that’s clearer instead of screwing up my first ever mallow attempt.

    1. Dikla

      Hi Courtney,

      Thank you for your message, the cookie recipe calls for 1/2 tsp vanilla. The marshmallow calls for 1 1/2 packs of powdered gelatin which is 3 tsp powdered gelatin.

      I hope this makes things clearer feel free to shot another comment if you have more questions.

    This recipe looks amazing!! I am in the UK and have never heard of Graham crackers crumbs, is this an essential ingredient? Please can you suggest an alternative?

    1. Dikla

      Graham crackers are basically sweet and crispy tea biscuit and an icon here in the states. I feel comfortable to say you can use a plain crispy cookie instead. One that you think would taste good with chocolate and marshmallow.

  4. Dikla

    I’m so excited to be on your email list! Can’t believe I wasn’t already!
    Congratulations on your cookbook, it looks so beautiful and informative!

Leave me your lovely thoughts
