Introduction

This S’mores Skillet Cookie brings the nostalgic campfire treat to your kitchen in a warm, gooey dessert that’s perfect for sharing. Crisp edges and a soft, marshmallow-studded center make it irresistible any time of year.

A large round dessert with a rough, golden-brown cookie crust forms the outer layer, studded with melted dark chocolate pieces scattered throughout. Inside, there's a soft melted dark chocolate layer mixed with gooey toasted marshmallows, creating a rich and sticky texture. In the center, three scoops of creamy white ice cream with vanilla speckles sit, slightly melting into the warm dessert. Two silver spoons are placed inside the dish, one near the edge and the other in the middle, partially digging into the dessert. The whole dish rests on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 cup melted unsalted butter
1 1/3 cup packed brown sugar
2/3 cup granulated sugar
2 large eggs (room temperature)
1 egg yolk (room temperature)
1 tbsp vanilla extract
3 cups all-purpose flour
1/2 tsp baking powder
1 tsp baking soda
2 tsp salt
2 cups semi-sweet chocolate chips (divided)
1/2 cup graham cracker crumbs (about 4 whole sheets, divided)
1 cup mini marshmallows (divided)

Instructions

Step 1: Preheat your oven to 350°F (180°C). Grease an oven-safe skillet thoroughly with butter or baking spray and set it aside.
Step 2: In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until the mixture is well combined.
Step 3: Add the eggs, egg yolk, and vanilla extract to the sugar mixture. Whisk until everything is fully incorporated.
Step 4: Using a rubber spatula, fold the flour, baking powder, baking soda, and salt into the wet ingredients. Fold gently until just a few dry streaks remain.
Step 5: Fold in 1 cup of the chocolate chips, the crumbs from 2 crushed graham cracker sheets, and ½ cup of mini marshmallows until the dough is mostly uniform.
Step 6: Transfer the dough to your prepared skillet and press it down evenly to fill the pan.
Step 7: Sprinkle the remaining chocolate chips, graham cracker crumbs, and mini marshmallows evenly over the top.
Step 8: Bake for 40 to 45 minutes, or until the edges are set and golden but the center remains soft and slightly springy to the touch.
Step 9: Remove from the oven and let the skillet cookie cool for about 10 minutes before serving. Optionally, top with ice cream for an extra indulgent treat.

Tips & Variations

For a toasted marshmallow flavor, briefly broil the cookie topping for 1-2 minutes after baking—watch carefully to avoid burning.
Substitute dark chocolate chips for semi-sweet to add a richer depth of flavor.
Use crunchy peanut butter swirled into the dough for a nutty twist on classic s’mores.
If you don’t have a skillet, a round cake pan works well as a baking alternative.

Storage

Store any leftover skillet cookie tightly covered at room temperature for up to 3 days. Reheat gently in the microwave for 15-20 seconds to revive its soft texture. For longer storage, freeze the baked cookie wrapped in foil for up to 2 months; thaw at room temperature before reheating.

How to Serve

A round baked dessert in a black cast iron skillet with a white handle sits on a white marbled surface. The dessert has one main layer of golden brown cookie base with melted chocolate chips and small toasted marshmallows scattered throughout. On top of this base are three smooth scoops of creamy vanilla ice cream placed in the center. Two spoons rest inside the skillet, one on the top left and the other on the bottom right of the ice cream. Around the skillet are scattered white mini marshmallows and a small white bowl filled with more mini marshmallows. Nearby, there is a clear glass of milk and a white plate stacked with two silver forks. A crumpled light beige cloth is on the bottom right corner of the image.

FAQs

Can I make this recipe without a cast iron skillet?

Yes, you can use any oven-safe skillet or a round baking pan about 9-10 inches in diameter. Just adjust baking time slightly if needed.

Why is the cookie center still soft after baking?

The cookie is meant to have a soft, slightly gooey center for that classic s’mores texture. If you prefer a firmer center, bake a few minutes longer but be careful not to overbake.
