May’s Cookie of the Month is a Frosted S’mores Cookie with a graham cracker cookie, a layer of silky chocolate, and a marshmallow frosting. Yes, I’m hopelessly devoted to it.
May’s Cookie of the Month
The Cookie: ‘Tell me, s’more! Tell me, s’more!’ Frosted S’mores Cookies
Inspired by summer’s favorite delicacy and “Grease”’s biggest hit – May’s ‘Tell me, s’more! Tell me, s’more!’ Cookie is not one to drop out on. A thick graham cracker cookie base (with graham cracker in the dough & crumbs on the outside!) is baked to soft, chewy, golden perfection. Then it is topped with a silky chocolate ganache-like situation and frosted with a fluffy marshmallow frosting. To put it simply, it is the one that I want and I’m definitely losing control.
The Movie: “Grease”
In honor of graduation season, we’re throwing it back with a watch party of “Grease”. Because a classic mallow/chocolate/graham treat moment deserves a classic movie, right? They just go together like “ramma-lamma-lamma-ka-dingity-da-dinga-dong”.
The Activity: ‘Drive-in’ viewing of Grease
Let me set the scene: you blow up an inflatable swimming pool and fill it with pillows and blankets until it is cozyyy. Then you and your friends grab an obscene amount of snacks (and cookies) and sing your hearts out while watching “Grease”. Bonus points if you project the movie onto the side of your house and do this all outside!
Ingredients in ‘Tell Me S’more’ Cookies
Cookie Base
- Salted butter, softened – I always use salted butter in my recipes! You can easily sub in unsalted butter, you may just want to add a pinch of salt to the dough.
- Brown sugar, packed
- Granulated sugar
- Eggs
- Vanilla
- All-purpose flour
- Graham crackers, crushed + divided – You will put crumbs into the dough AND roll the finished dough balls in crumbs, too.
- Baking soda
- Baking powder
- Salt
Chocolate Layer
- Chocolate chips – I used milk chocolate, because it kind of felt necessary for s’mores? But you can use semisweet or dark chocolate if that is your preference.
- Sweetened condensed milk
Marshmallow Frosting
- Butter, softened – Again, I used salted butter!
- Powdered sugar
- Vanilla extract
- Marshmallow creme – I found this at my grocery store in the baking aisle.
How to Make Frosted S’mores Cookie
- Preheat the oven to 350°F. Line a cookie sheet with parchment paper or a silicone baking mat and set aside.
- In the bowl of the stand mixer or with an electric hand mixer, cream together the butter, brown sugar and granulated sugar until light in color and fluffy in texture.
- Scrape the sides of the bowl and then mix in the eggs and vanilla.
- Add the flour, 1 1/2 cups graham cracker crumbs (reserving the remaining crumbs for later), baking soda, baking powder and salt. Mix until a dough forms.
- Portion the dough out into 3 tbsp portions. Roll into a ball and then roll into the remaining graham crackers crumbs before arranging on the prepared baking sheet.
- Repeat with remaining dough.
- Bake at 350°F for 11-13 minutes or until the cookies have spread and the centers no longer look glossy.
- Remove from the oven and allow the cookies to cool.
- Once cool, microwave the chocolate chips and sweetened condensed milk together for 30 seconds at a time until smooth. Stir between intervals.
- Once smooth, spread the chocolate onto the top of each cookie.
- Allow the chocolate layer to set, and once set, make the marshmallow frosting by combining the butter, powdered sugar, vanilla and marshmallow cream until smooth.
- Spread the frosting onto the top of each cookie and top with some graham cracker crumbs. You can also add a square of chocolate, if desired.
- Store at room temperature for up to 3 days. Enjoy!

My new favorite cookie recipe by far! I am never disappointed by any cookie recipes Karli creates. Made a batch for my boyfriend to bring to work and they were a big hit! Not one cookie made it back home!
Made these this week and my friends all devoured them. Was planning to bring extras to work but there were none left. Will have to make a double batch next time to keep up with the demand :). Thanks for your posts! Love these recipes
I’m going to try these tomorrow thanks for the recipe they look amazing
These turned out delicious! Love the amount of graham cracker in the cookie so good. They turned out really good thanks for the recipe.
Made these for the first time and they were a big hit with everyone! Certainly will be my go to recipe for S’mores cookies
I made these last week for my family and co-workers and also my husband’s co-workers…let’s just say they went SUPER fast and was told it was the BEST cookie I’ve made thus far!!! (I’ve made MANY cookies for them, so that’s saying something!) Thank you for your wonderful recipes Karli! Much love from Wisconsin.
My sons new favorite cookie him and my husband loved them
These cookies are serious to die for. Im typically nervous to try recipes that don’t have metric measurements since I’m a bit of a perfectionist, but have made these three times now without issue! These taste like summer nights in cookie form. The graham cracker cookie is soft and chewy which in my opinion is a HUGE level up from the traditional crunchy graham cracker in s’mores. That being said you still get an incredible graham cracker flavor in the cookie. For my last batch, I added 1/2 tsp salt to the graham cracker I rolled the dough balls in to cut a little bit of the sweetness and they turned out even better (I didn’t think that was possible). I’ve made hundreds of cookies in my life and this to be my new favorite to make in the summertime. Thank you!!! 🌟🌟🌟🌟🌟
I made these for my friends and family and they LOVED them SO SO much. I sell cookies, and these are by far my best sellers! They do take a while to make, but are totally worth it!! Amazing!!
These are delicious! However, are you sure the yield is 40 cookies? I made them smaller than 3 tbsp each and got way less than 40 cookies.
