Introduction

This s’mores cake brings the classic campfire treat into a deliciously rich dessert perfect for any occasion. Layers of buttery graham cracker dough, melted chocolate, and fluffy marshmallow fluff combine to create a gooey and irresistible cake that everyone will love.

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 with the brown and granulated sugars until creamy and well combined.
Step 2: Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract until the mixture is light and fluffy.
Step 3: In a separate bowl, mix together the all-purpose flour, kosher salt, and graham cracker crumbs until evenly combined.
Step 4: Gradually add the dry ingredients to the butter mixture, mixing until a uniform dough forms.
Step 5: Divide the dough in half. Press one half evenly into the bottom of a greased 9×13-inch baking dish to form the base layer.
Step 6: Arrange three whole Hershey bars side by side over the dough layer. Cut the remaining bar into four lengthwise strips and fill the gaps around the whole bars to cover the surface completely.
Step 7: Evenly spread the entire 16-ounce jar of marshmallow fluff over the chocolate layer, covering it completely.
Step 8: Crumble the remaining half of the dough into small pieces and sprinkle them evenly over the marshmallow fluff. Gently pat the crumbs down to help them stick.
Step 9: Bake the assembled cake, uncovered, on the center rack of the oven 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 gooeyness, add a sprinkle of mini marshmallows on top before baking.
Use your favorite chocolate bars or even a mix of milk and dark chocolate for varied flavor.
Let the cake cool fully to help the layers set and prevent the marshmallow from oozing out when sliced.
For a nutty twist, sprinkle chopped toasted nuts over the marshmallow layer before adding the crumb topping.

Storage

Store any leftover 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 slices gently in the microwave for about 10-15 seconds to bring back the melty texture without drying out the cake.

How to Serve

The image shows a square slice of layered dessert on a white plate, placed on a white marbled surface. The dessert has four distinct layers: a crumbly golden brown crust at the bottom, a pale yellow creamy layer above it, followed by a smooth, light brown chocolate layer in the middle, and topped with a thick, fluffy white topping that has a slightly toasted light brown surface. The layers are clearly visible and each has a different texture and color that contrasts well with the others. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular marshmallows instead of marshmallow fluff?

While marshmallow fluff spreads more evenly, you can substitute with regular marshmallows by melting them gently before spreading or layering them directly over the chocolate. Be prepared for a slightly different texture and appearance.

What can I use if I don’t have graham cracker crumbs?

If graham cracker crumbs aren’t available, you can crush digestive biscuits or similar mildly sweet cookies as a substitute. They will provide a similar texture and flavor base for the cake.
