Ingredients

Scale

Butter Mixture

1 cup unsalted butter, softened
1/2 cup brown sugar
1 cup granulated sugar
2 eggs
2 teaspoons pure vanilla extract

Dry Ingredients

2 2/3 cups all-purpose flour
3/4 teaspoon kosher salt
1 1/2 cups graham cracker crumbs

Other

4 XL Hershey bars (4.4 ounce size each)
16 ounces marshmallow fluff

Instructions

Preheat Oven and Prepare Butter Mixture: Preheat your oven to 350°F. In a large mixing bowl, beat the softened butter with both brown and granulated sugars until the mixture is creamy and well combined.
Add Eggs and Vanilla: Incorporate the eggs one at a time along with the pure vanilla extract. Continue beating until the mixture becomes light and fluffy, which should take a few minutes.
Combine Dry Ingredients: In a separate bowl, thoroughly mix the all-purpose flour, kosher salt, and graham cracker crumbs together.
Mix Dry into Wet: Gradually add the dry ingredient mixture into the butter mixture. Mix until the dough is evenly combined.
Assemble First Cake Layer: 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.
Add Chocolate Bars: Place three whole Hershey bars side by side over the dough layer. Cut the remaining chocolate bar into four lengthwise strips and arrange these in the gaps around the whole bars, covering the entire surface.
Spread Marshmallow Layer: Evenly spread the entire 16-ounce jar of marshmallow fluff over the chocolate layer, covering it completely.
Top with Crumbled Dough: Crumble the remaining half of the dough into small pieces and sprinkle them evenly over the marshmallow fluff layer. Gently pat down the crumbs to ensure some adherence.
Bake the Cake: Place the baking dish uncovered on the center rack of the preheated oven. Bake for 30 to 35 minutes until the top turns golden brown and puffed.
Cool and Serve: Allow the cake to cool completely before slicing into 16 pieces. Cooling helps the layers set for easier serving.

Notes

Ensure the butter is softened to room temperature for easy mixing.
Press the dough firmly at the base to create a solid layer; this supports the toppings well.
Using a greased baking dish prevents sticking and helps with easy removal.
Let the cake cool thoroughly to avoid melting layers when slicing.
This cake can be stored covered at room temperature for up to 2 days or refrigerated for up to 4 days.
