3-Ingredient S’mores Cookie Bars capture all the nostalgia of a classic campfire treat in a warm, effortless baked dessert. By layering pre-made chocolate chip cookie dough with classic milk chocolate bars and sweet marshmallow creme, this simple recipe builds gooey, indulgent layers without all the mess of an open flame. It is a brilliant go-to treat for potlucks, birthday parties, or a fun weekend baking project with the family when you are craving something sweet in a hurry.

What makes these dessert bars so delightful is how the three simple components transform in the oven. As the bars bake, the soft cookie dough rises and turns golden, melting the chocolate underneath while the marshmallow creme creates a soft, gooey center. Whether you serve them warm straight from the pan for an extra melt-in-your-mouth texture or let them cool completely for neat, clean slices, these bars are guaranteed to satisfy any sweet tooth.

3-Ingredient S’mores Cookie Bars

Ingredients:

Step-By-Step Directions:

1. Preheat and Prepare: Preheat the oven to 350°F. Lightly grease a 9×13-inch glass baking dish or line it with parchment paper for easier removal after baking.

2. Form the Base Layer: Slice the 1/16.5 oz roll of refrigerated chocolate chip cookie dough in half. Press one half evenly into the bottom of the prepared baking dish to form the base layer.

3. Add the Chocolate: Lay the 4/1.55 oz milk chocolate bars over the dough in an even layer, breaking the bars into pieces as needed so they cover most of the surface.

4. Spread the Marshmallow Creme: Spoon the 1/7 oz jar of marshmallow creme over the chocolate layer and gently spread it as evenly as you can. It may not spread perfectly, and that is completely fine.

5. Top with Remaining Dough: Flatten pieces of the remaining half of the cookie dough with your hands and place them across the top to cover most of the marshmallow creme. Some small gaps are fine because the dough will spread out as it bakes.

6. Bake and Cool: Bake for 25 to 30 minutes, or until the top is golden brown and the edges are set. Cool the bars in the pan for at least 20 minutes before slicing so the gooey layers can settle properly.

7. Slice and Serve: Cut into squares and serve warm for extra gooey layers, or let them cool completely for neater, cleaner bars.
