S’mores Bars Ingredients
For the Crust
- 1 cup graham cracker crumbs – This forms the base of your S’mores Bars, giving them that classic, crunchy texture.
- 1/4 cup granulated sugar – Sweetens the crust and helps it bind together beautifully.
- 1/2 cup unsalted butter (melted) – Adds richness and moisture to the crust for a gooey finish.
- 1/4 teaspoon salt – Enhances the flavors and balances the sweetness of the ingredients.
For the Filling
- 1 cup chocolate chips (semi-sweet or milk chocolate) – Melts perfectly to create a luscious, chocolatey layer in your S’mores Bars.
- 1 cup mini marshmallows – Provides that essential gooeyness and marshmallow flavor reminiscent of traditional s’mores.
- 1/2 cup chocolate bars (broken into pieces) – Adds extra chunks of chocolate for delightful bites throughout the bars.
How to Make S’mores Bars
1. Preheat the oven to 350°F (175°C). In a mixing bowl, combine 1 cup of graham cracker crumbs, 1/4 cup of granulated sugar, 1/2 cup of melted unsalted butter, and 1/4 teaspoon of salt. Mix until everything is well blended and crumbly.
2. Press the mixture firmly into the bottom of a greased 9×9 inch baking pan. Ensure it’s even and compact for a sturdy base that holds all that gooey goodness.
3. Sprinkle 1 cup of chocolate chips evenly over the crust. This layer will melt beautifully during baking, creating a delightful chocolate foundation.
4. Add 1 cup of mini marshmallows and 1/2 cup of broken chocolate bars on top of the chocolate chips. This is where the magic happens—the melty marshmallows will create that iconic s’mores experience.
5. Bake in the preheated oven for 20-25 minutes, or until the marshmallows are golden brown and the chocolate is perfectly melted and bubbly. Keep an eye on it; you want that perfect toasted look!
6. Cool before cutting into bars. Allow them to set for a bit after removing from the oven; this helps maintain their shape when you slice them up.
Optional: Drizzle with melted chocolate for an extra indulgent treat!

Tips for the Best S’mores Bars
- Graham Cracker Consistency: Ensure your graham cracker crumbs are fine for a smoother crust; large chunks can lead to uneven baking.
- Butter Measurement: Use melted butter, not softened. Melted butter helps bind the crust properly, preventing it from crumbling.
- Layering Chocolate: Distribute chocolate chips evenly before adding marshmallows. This ensures every bite of your S’mores Bars has that rich chocolatey goodness.
- Marshmallow Browning: Keep an eye on the marshmallows while baking; they can go from golden to burnt quickly. A little patience goes a long way!
- Cooling Time: Allow the bars to cool completely before cutting; this helps them set and makes slicing much easier, resulting in neat, beautiful bars.
How to Store and Freeze S’mores Bars

- Room Temperature: Keep your S’mores Bars in an airtight container for up to 3 days to maintain their gooey texture and delightful flavor.
- Fridge: For extended freshness, store the bars in the refrigerator for up to 1 week. Just be sure to wrap them tightly to prevent drying out.
- Freezer: You can freeze your S’mores Bars for up to 2 months. Wrap each bar individually in plastic wrap and place them in a freezer-safe bag.

- Peanut Butter: Swirl in 1/2 cup of creamy peanut butter into the chocolate layer for a nutty, delicious twist. The combination of chocolate and peanut butter is timeless, offering a rich contrast to the sweetness of the marshmallows.
