A decadent, multi-layered dessert bar combining chocolate chip cookie dough, graham crackers, gooey marshmallows, and rich chocolate, inspired by classic campfire smores with a fun, chaotic twist.

The first time I baked these Chaos Cake Smores Cookie Bars for a casual get-together, every square disappeared in minutes. Friends loved the combination of textures, with gooey marshmallow, crisp graham cracker, and melty chocolate in one bite.

Ingredients

  • Cookie Dough Layer: 1 cup (225 g) unsalted butter, softened, 1 cup (200 g) light brown sugar, packed, 1/2 cup (100 g) granulated sugar, 2 large eggs, 2 tsp vanilla extract, 2 1/2 cups (315 g) all-purpose flour, 1 tsp baking soda, 1/2 tsp salt, 2 cups (340 g) semisweet chocolate chips
  • Smores Layers: 8 full sheets graham crackers, 2 cups (100 g) mini marshmallows, 8 oz (225 g) milk chocolate bars, broken into pieces
  • Topping: 1/2 cup (85 g) chocolate chips, 1/2 cup (25 g) mini marshmallows, 1 graham cracker, crushed

Instructions

Prepare the Pan:
Preheat oven to 350°F (175°C). Line a 9x13-inch (23x33 cm) baking pan with parchment paper, leaving an overhang for easy removal.
Make Cookie Dough:
In a large bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy. Beat in eggs one at a time, then add vanilla extract.
Combine Dry Ingredients:
In a separate bowl, whisk together flour, baking soda, and salt.
Finish Dough:
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Fold in the chocolate chips.
Layer and Build:
Press half of the cookie dough evenly into the prepared pan. Arrange graham cracker sheets in a single layer over the dough, breaking as needed to cover. Sprinkle mini marshmallows and the milk chocolate bar pieces evenly over the graham crackers. Drop spoonfuls of the remaining cookie dough over the top, gently spreading to cover as much as possible. Sprinkle with additional chocolate chips, mini marshmallows, and crushed graham cracker.
Bake:
Bake for 28–32 minutes, or until golden brown and set. The center should be slightly gooey.
Cool and Serve:
Cool completely in the pan before lifting out and cutting into bars.
