Introduction

This S’mores Cake brings together all the best flavors of the classic campfire treat in a delicious, baked dessert. Layers of graham cracker dough, rich chocolate, and fluffy marshmallow fluff create a gooey, indulgent cake perfect for sharing with family and friends.

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. Beat the mixture until it becomes light and fluffy, about a few minutes.
Step 3: In a separate bowl, mix the all-purpose flour, kosher salt, and graham cracker crumbs thoroughly.
Step 4: Gradually add the dry ingredients to the wet butter mixture and mix until evenly combined, forming a 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 chocolate bar into four lengthwise strips and arrange them in the gaps around the whole bars to cover the surface.
Step 7: Evenly spread the entire 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 down the crumbles to help them stick.
Step 9: Bake the assembled cake uncovered on the center rack for 30 to 35 minutes, or 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 gooey chocolate, add chocolate chips or chunks inside the dough before baking.
Use your favorite chocolate bars or mix milk and dark chocolate for a richer flavor.
To avoid burning the top, tent the cake with foil halfway through baking if it browns too quickly.
Try adding chopped nuts or toasted coconut on top for added texture and flavor.

Storage

Store leftover S’mores Cake in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Reheat slices gently in the microwave for 15 to 20 seconds to soften the marshmallow layer before serving.

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?

Marshmallow fluff is smoother and easier to spread, but you can melt regular marshmallows with a little cream or butter and spread that mixture as a substitute.

Is it necessary to use graham cracker crumbs in the dough?

The graham cracker crumbs add the classic flavor and texture reminiscent of s’mores. You can substitute with finely crushed digestive biscuits or vanilla wafer crumbs if desired.
