How to Make S’mores Seven Layer Bars
-
Preheat and Prepare: Preheat your oven to 350°F. Spray a 9×13 inch baking dish with non-stick cooking spray or line it with parchment paper to ensure easy removal later.
-
Make the Base: In a small bowl, combine the graham cracker crumbs with the melted butter. Mix well until it’s crumbly and press this mixture evenly into the prepared baking dish.
-
Layer the Sweetness: Pour the sweetened condensed milk over the crumb base. Then, sprinkle half of the mini marshmallows, all chocolate chips, and broken graham cracker pieces over the top for that irresistible filling.
-
Bake It Up: Place the dish in the preheated oven and bake for 15 minutes. When time’s up, sprinkle the remaining marshmallows on top and return to the oven for another 10-15 minutes, until the marshmallows are golden brown and the edges are delightful.
-
Finishing Touch: Once out of the oven, transfer the dish to a cooling rack. Immediately place the broken chocolate bars on top to let them melt slightly. Allow to cool for at least 15 minutes before cutting into squares for serving—better yet, let them cool completely for best results.
Optional: Drizzle with extra melted chocolate for a decadent finish.

S’mores Seven Layer Bars Recipe FAQs
What type of graham crackers should I use for the base?
Absolutely, you can use any brand of graham crackers available to you! Look for ones that are fresh and crisp, as they provide the best crunch. If you prefer a slightly different flavor profile, consider using cinnamon graham crackers to add a hint of spice to your bars.
How should I store leftover S’mores Seven Layer Bars?
The more the merrier! To keep your S’mores Seven Layer Bars at their best, store them in an airtight container at room temperature for up to 3 days. If you want to keep them fresh longer, you can refrigerate them for up to a week. Just make sure to wrap them well to prevent drying out.

What if my marshmallows burn while baking?
Very! That can happen if they are exposed to heat for too long. To avoid this, keep an eye on them towards the end of the baking time. If they start to brown too quickly, you can place a piece of aluminum foil over the top to protect them while allowing the rest to bake thoroughly.
