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!
