How to Make S'mores Cookie Bars – Easy Homemade Gooey Treat
Step 1 — Prep & Preheat
Prep the dough: In a large bowl, cream together softened butter, granulated sugar, and brown sugar until light and fluffy. Beat in eggs one at a time, then stir in vanilla extract.
Step 2 — Cook and Build Flavor
Mix dry ingredients: In a separate bowl, whisk together flour, baking soda, salt, and cinnamon (if using). Gradually blend dry ingredients into the wet mixture until just combined.
Step 3 — Finish, Taste, and Adjust
Layer the bars: Preheat oven to 350°F. Spread half the cookie dough evenly in a greased 9x13-inch pan. Sprinkle graham cracker crumbs evenly over the dough, then layer with chocolate chips and mini marshmallows. Carefully spread remaining dough over the top in dollops, gently covering the marshmallow layer without mixing.

You can substitute crushed digestive biscuits or vanilla wafers if graham crackers aren’t available; they provide a similar texture and slight sweetness.
Keep leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days.
