How to make Smores Cookie in a Skillet
Now that you’ve got all the ingredients gathered, let’s walk through how to make the graham cracker cookie crust, then turn that into a smores skillet cookie.
Step 1: Mix the Dry Ingredients
In a mixing bowl, whisk together flour, 1 cup graham cracker crumbs, cornstarch, baking soda, and salt.
Step 2: Cream the Butter and Sugars
In a separate bowl, beat softened butter, granulated sugar, and brown sugar until fluffy. Add the egg and vanilla, and mix until smooth.
Step 3: Make the Dough
Gradually mix the dry ingredients into the wet mixture until a soft cookie dough forms.
Step 4: Press Into the Skillet
Evenly press the cookie dough into a 12-inch cast iron skillet. Sprinkle the remaining ¼ cup graham cracker crumbs over the top.
Step 5: Bake
Bake at 325ºF for 20–25 minutes or until the edges are golden and the center is set. A toothpick inserted should come out clean.
Step 6: Add the Chocolate
Sprinkle milk chocolate chips on the hot cookie and let them melt. Spread evenly, leaving a border around the edge.
Step 7: Top with Marshmallow Fluff
Drop spoonfuls of marshmallow fluff over the chocolate. Return to the warm oven for 1 minute to soften, then spread gently.
Step 8: Toast the Marshmallow
Turn on the broiler and toast the top for 30–60 seconds. Keep a close eye on it—marshmallow burns fast!
How to Serve and Storage
Serve this warm Smores cookie recipe right out of the skillet! The cookie will be soft and gooey, the chocolate melty and the marshmallow cooked just right.
The cookie base will be more soft and crumbly while it is warm, but will set up a little more as it cools.
This cookie can be stored in an airtight container on the countertop for up to 3 days, it won’t be as good as the first day, but all the delicious smores flavors will be there.
Want to make it even better? Heat in the microwave for 30 seconds!
Recipe FAQs
Yes! Use mini marshmallows and scatter them over the chocolate. Broil until toasted.
I like to use milk chocolate for that classic s’mores flavor, but dark chocolate or even chocolate bars work great too!
You can make the cookie dough a day ahead and refrigerate it. Press into the skillet just before baking.

Notes
- Nutrition facts are just an estimate of the ingredients listed.
- For the graham cracker crumbs, I prefer to make the crumbs added to the cookie finer and the 1/4 cup placed on top a little more coarse.
- Store in an airtight container on the countertop for up to 3 days. Do not store in the cast iron skillet.
- to make ahead, bake the graham cracker cookie and add the chocolate and marshmallow before serving, just use the oven to heat and melt the chocolate and marshmallow fluff
