Recipe Ingredients

Toasted marshmallows and Hershey's chocolate bars on top of a S'mores Cookie Skillet.
  • Semi-Sweet Chocolate Chips: Adds a smooth and slightly bitter taste that balances the sweetness of the marshmallows and sugar.
  • Mini Marshmallows: They melt into soft, gooey goodness, creating little pockets of sweetness throughout the cookie.
  • Graham Cracker Crumbs & Chunks: A mix of crisp and crumbly, these add a light sweetness with a hint of cinnamon.

For a full list of ingredients and amounts, see the recipe card below.

Variations

  • Add-Ins: You can mix in chopped nuts like pecans or almonds for a little crunch, or swirl in some peanut butter or Nutella for added richness. If you’re feeling extra indulgent, try adding caramel bits or even extra chocolate varieties.
  • Butter Alternative: You can easily swap the melted butter for coconut oil if you’re looking for a dairy-free option. It adds a subtle hint of coconut.

Step 1: Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius).

Step 2: In a large mixing bowl or the bowl of a stand mixer, add the melted butter, sugars, egg, egg yolk, and vanilla. Beat the mixture for 30 seconds, then let it rest for 30 seconds. Repeat this process 3 times.

Step 3: In a small mixing bowl, whisk together the flour, graham cracker crumbs, salt, baking soda, and cinnamon. Using a spatula or wooden spoon, stir in the dry ingredients. Fold in ½ cup + 2 tablespoons of the chocolate chips and ½ cup of mini marshmallows.

Step 4: Press the mixture into a 10-12 inch cast iron skillet, creating a slight mound in the center (this is because the edges tend to rise during the baking process). Top with the remaining chocolate chips, mini marshmallows, graham cracker chunks, and chocolate bar pieces.

Step 5: Place in the oven and bake until the center is mostly set, about 18-20 minutes. Remove and place the halved marshmallows (cut/sticky side down) around the edges of the cookie, spacing them about ¼ inch apart. Return to the oven and continue baking until the marshmallows turn golden brown on top. Remove from the oven and allow to cool for 15-20 minutes before slicing and serving.

  1. It was super delicious, but it took longer to cook than listed and turned the entire marshmallow bronzed instead of just the surface. Overall pretty fun and easy to put together!
