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

Layers

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 (175°C). In a large mixing bowl, beat the softened butter with brown and granulated sugars until creamy and well combined.
Add Eggs and Vanilla: Incorporate the eggs one at a time, mixing well after each addition, then add the vanilla extract. Beat the mixture until it becomes light and fluffy, which takes a few minutes.
Combine Dry Ingredients: In a separate bowl, thoroughly mix together the all-purpose flour, kosher salt, and graham cracker crumbs.
Mix Dry into Wet: Gradually add the dry ingredients to the butter-sugar mixture, mixing until evenly combined to form a dough.
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 them in the gaps around the whole bars to cover 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. Gently pat down the crumbles to help them stick slightly.
Bake the Cake: Place the baking dish uncovered on the center rack of the preheated oven. Bake for 30 to 35 minutes or until the top is golden brown and puffed.
Cool and Serve: Allow the cake to cool completely before slicing into 16 pieces to help the layers set for easier serving.

Notes

Use room temperature softened butter for easier mixing and better texture.
You can substitute Hershey bars with your favorite chocolate bars if desired.
The marshmallow fluff layer provides the classic gooey texture so be sure to spread it evenly.
Cooling the cake fully is important for clean slicing and to keep layers intact.
Store leftovers in an airtight container at room temperature for up to 3 days.
