Buttery cookie bars layered with chocolate spread and gooey marshmallows for a nostalgic, indulgent dessert.

# The Ingredients You'll Need:

→ Cookie Dough

01 - 1 cup unsalted butter, softened
02 - 1 cup packed brown sugar
03 - 0.5 cup granulated sugar
04 - 2 large eggs
05 - 2 teaspoons vanilla extract
06 - 2.5 cups all-purpose flour
07 - 1 teaspoon baking soda
08 - 0.5 teaspoon salt
09 - 1 cup graham cracker crumbs
10 - 1 cup semi-sweet chocolate chips

→ Filling

11 - 1.5 cups milk chocolate spread
12 - 2 cups mini marshmallows

# Step-by-Step Instructions:

01 - Preheat the oven to 350°F (175°C) and line a 9×13-inch baking dish with parchment paper to prevent sticking and allow easy removal.
02 - In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, forming the base for the dough.
03 - Beat in the eggs one at a time, mixing thoroughly after each addition, then stir in vanilla extract to enhance flavor.
04 - Whisk together the all-purpose flour, baking soda, salt, and graham cracker crumbs until evenly blended for consistent texture.
05 - Gradually add dry ingredients to the wet mixture, mixing just until incorporated to avoid overworking. Fold in semi-sweet chocolate chips evenly.
06 - Press half of the cookie dough evenly into the prepared baking dish to create a solid base layer.
07 - Spread the milk chocolate spread evenly over the cookie dough base, then sprinkle the mini marshmallows evenly on top.
08 - Flatten remaining dough into pieces and gently place over the marshmallow layer, covering as much as possible to seal the filling.
09 - Bake for 25 to 30 minutes until the top is golden brown, avoiding overbaking to maintain moistness.
10 - Allow bars to cool completely in the baking dish before slicing into squares to set for clean cuts and optimal texture.

# Extra Tips:

01 - Use softened (not melted) butter for ideal creaming. Avoid overmixing when adding dry ingredients to keep a tender crumb. Parchment paper helps lift bars easily. For extra gooey texture, add more mini marshmallows in filling.
02 - Store leftovers in an airtight container at room temperature for up to 3 days or freeze for longer preservation.
