Introduction

This s’mores cake captures all the classic campfire flavors in a rich, gooey dessert perfect for any occasion. Layers of buttery dough, melted chocolate, and fluffy marshmallow fluff come together for a crowd-pleasing treat that’s sure to satisfy your sweet tooth.

The image shows a square piece of layered dessert on a white plate, placed on a white marbled surface. The bottom layer is a crumbly, golden-brown crust that looks crunchy. Above this is a light yellow pudding layer that is smooth and creamy. On top of the pudding is a thick, rich chocolate pudding layer with a glossy texture. The dessert is topped with a thick, fluffy white whipped cream layer that is toasted with light brown spots, giving it a slightly burnt look. The layers are clearly visible, stacked neatly.

Ingredients

1 cup unsalted butter, softened
1/2 cup brown sugar
1 cup granulated sugar
2 eggs
2 teaspoons pure vanilla extract
2 2/3 cups all-purpose flour
3/4 teaspoon kosher salt
1 1/2 cups graham cracker crumbs
4 XL Hershey bars (4.4 ounce size each)
16 ounces marshmallow fluff

Instructions

Step 1: Preheat your oven to 350°F. In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until creamy and well combined.
Step 2: Add the eggs one at a time along with the vanilla extract, beating until the mixture is light and fluffy.
Step 3: In a separate bowl, combine the all-purpose flour, kosher salt, and graham cracker crumbs thoroughly.
Step 4: Gradually add the dry ingredients to the butter mixture and mix until it forms an even dough.
Step 5: Divide the dough in half. Press one half evenly into the bottom of a greased 9×13-inch baking dish to create the base layer.
Step 6: Place three whole Hershey bars side by side over the dough. Cut the remaining bar into four lengthwise strips and arrange these strips around the whole bars to cover the surface.
Step 7: Evenly spread the entire jar of marshmallow fluff over the chocolate layer.
Step 8: Crumble the remaining half of the dough into small pieces and sprinkle them evenly over the marshmallow fluff. Gently pat down the crumbles.
Step 9: Bake the cake uncovered on the center oven rack for 30 to 35 minutes, until the top is golden brown and puffed.
Step 10: Allow the cake to cool completely before slicing into 16 pieces for easier serving.

Tips & Variations

For extra crunch, sprinkle chopped nuts such as pecans or walnuts over the marshmallow layer before adding the dough crumbles.
Substitute regular chocolate bars with dark or milk chocolate based on your preference.
Use mini marshmallows instead of marshmallow fluff if you prefer a different texture.

Storage

Store the s’mores cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. Reheat individual pieces briefly in the microwave to restore gooeyness before serving.
