S’mores Cookie Bars Recipe

The First Bite That Started It All

The smell of toasted marshmallow hit me first—warm, sweet, and smoky. Then came the crunch of graham cracker, the melt of chocolate. One bite, and I was hooked. Ever wondered how you could turn campfire s’mores into a no-mess, anytime treat? These bars are the answer. They’re like summer nights packed into a pan, ready to share.

My Sticky (But Sweet) Kitchen Adventure

My first try? Marshmallow creme everywhere—fingers, counter, even my cat’s paw. The dough stuck like glue, but the bars still tasted like heaven. Cooking teaches patience, and sometimes, messy is better. Now I keep wet towels nearby for quick clean-ups. Share your own kitchen mishaps below—did your first bake turn out perfect or chaotic?

Why These Bars Hit Different

– Graham crumbs add a toasty depth you can’t get from flour alone. – The marshmallow layer puffs up just enough—gooey, not gummy. Which flavor combo surprises you most—brown sugar and vanilla or chocolate and marshmallow? Try both and decide.

From Campfires to Cookie Tins

S’mores began in the 1920s, thanks to Girl Scout handbooks. *Did you know graham crackers were once a health food?* These bars skip the fire but keep the fun. They’re proof that great ideas evolve. Vote: classic s’mores or these bars—which wins your heart?

How to Make S’mores Cookie Bars


Step 1

Preheat your oven to 350°F. Line an 8- or 9-inch pan with parchment paper. Let the paper hang over the edges. This makes cleanup easy. (Hard-learned tip: Cold butter won’t cream well. Let it soften first.)
Step 2 Beat butter and brown sugar until fluffy. Add the egg and vanilla. Mix until just combined. Don’t worry if it looks lumpy. What’s the best way to soften butter fast? Share below!
Step 3 Whisk flour, graham crumbs, baking powder, and salt. Add this to the wet mix. Stir until no dry spots remain. (Hard-learned tip: Spoon flour into cups. Scooping packs too much.)
Step 4 Press 2/3 of the dough into the pan. Spread marshmallow creme on top. Add chocolate chips. Crumble the rest of the dough over it. (Hard-learned tip: Wet your fingers to press sticky dough easier.)
Step 5 Bake 25–30 minutes until golden. Cool completely before cutting. Use the parchment to lift the bars out. Cook Time: 25–30 minutes Total Time: 45 minutes Yield: 9–12 bars Category: Dessert, Cookies

3 Fun Twists on S’mores Bars

Storing and Serving Tips

These bars stay fresh at room temp for a week—just cover them tight. For longer storage, freeze them in slices for up to 3 months. Thaw overnight before serving. Want warm gooeyness? Microwave a slice for 10 seconds. *Fun fact: My grandkids sneak them cold from the freezer!* Double the batch for parties—they vanish fast. Why this matters: Fresh marshmallow creme can dry out, so sealing matters. Ever tried freezing s’mores bars? Share your tricks below!

Quick Troubleshooting

Dough too sticky? Chill it 15 minutes—easier to press. Marshmallow layer uneven? Wet your spoon lightly to spread smoother. Bars crumble when cutting? Cool them fully first. Why this matters: Graham crumbs absorb moisture, so patience prevents cracks. Had a baking fail? Tell me—we’ve all been there!
