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 sugar and granulated sugar 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, whisk together the flour, kosher salt, and graham cracker crumbs until evenly mixed.
Step 4: Gradually add the dry ingredients to the butter mixture, stirring until a dough forms and everything is evenly combined.
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: Lay three whole Hershey bars side by side over the dough layer. Cut the remaining chocolate bar into four lengthwise strips and arrange these strips to fill the gaps, covering the surface completely.
Step 7: Spread the entire jar of marshmallow fluff evenly 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 the crumbles down to help them adhere.
Step 9: Bake the cake uncovered on the center rack of the oven 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 to make serving easier and to let the layers set.

Tips & Variations

For extra gooey texture, add mini marshmallows on top of the marshmallow fluff before adding the crumb topping.
Use dark chocolate bars instead of Hershey’s for a richer, less sweet flavor.
Press the crumb topping lightly to prevent it from falling off when serving.
Make sure the butter is fully softened to achieve a smooth, creamy dough mixture.

Storage

Store any leftover S’mores Cake in an airtight container at room temperature for up to 3 days. For longer storage, keep it covered in the refrigerator for up to one week. To enjoy the gooey texture, warm individual slices slightly in the microwave before serving.

FAQs

Can I use regular marshmallows instead of marshmallow fluff?

Marshmallow fluff provides a smooth and spreadable layer that melts evenly. If using regular marshmallows, melt them gently and spread carefully, but the texture will be different and less uniform.

Is it possible to make this cake gluten-free?

Yes, substitute the all-purpose flour with a gluten-free flour blend and ensure the graham cracker crumbs are gluten-free. The texture may vary slightly, but it will still be delicious.
