Inside Out S’mores Bars

Sharing is caring!

S’mores are the ultimate campfire treat, but not everyone wants to fuss with a fire to enjoy that perfect combo of chocolate, graham crackers, and marshmallows. That’s where these Inside Out S’mores Bars come in. They take everything you love about the traditional treat and flip it. Instead of a toasted marshmallow sandwich, you get a thick, chewy bar with layers of gooey chocolate and marshmallow, surrounded by a soft graham cracker-inspired cookie base. It’s nostalgic, satisfying, and way easier to make in your kitchen oven.

This recipe is all about texture. The cookie base is soft and chewy with a hint of graham flavor, thanks to crushed graham crackers blended into the dough. The center is layered with chocolate chips and marshmallow creme, which melt into a rich, sticky middle layer as it bakes. The result is a dessert bar that gives you that campfire flavor in every bite, no flame required.

One of the biggest upsides is how easy they are. Everything goes into a baking pan—no fire, no sticks, no melting mess. It’s a one-bowl dough and a single pan, but the final result looks like something you’d see in a bakery window.

These bars are perfect for gatherings. Cut them into squares and stack them high on a platter, and they’ll disappear in minutes. They hold their shape well and taste even better the next day. That makes them great for make-ahead events like parties, potlucks, or family dinners.

You can also switch up the chocolate: try semi-sweet, milk, or even dark chocolate depending on how rich you want them. And because the marshmallow creme stays gooey even after cooling, these bars stay soft and indulgent for days.

Kids absolutely love these. They get the fun and flavor of s’mores in a neat, easy-to-eat format. And adults appreciate how these bars manage to be indulgent without being overly sweet or heavy.

Another plus: you can double the recipe easily and bake it in a larger pan for a crowd. Or make a half batch if you just want a few to enjoy for the week.

These bars pack and travel well, so they’re ideal for picnics, road trips, or lunchbox treats. You won’t need to worry about melting or crumbling like you would with traditional s’mores.

They’re also a fun baking project with kids. The layering is easy and satisfying, and it’s always exciting to cut into the finished pan and see the chocolate and marshmallow ribbons inside.

If you’re looking for something with familiar flavors but a creative twist, these bars deliver. They’re playful, rich, and satisfying.

Even better? You don’t need any special equipment—just a mixing bowl, spoon, and baking dish.

So if you’re craving that classic campfire dessert without leaving your house, these Inside Out S’mores Bars are the answer. They’re quick, fun, and absolutely addictive.

Servings

Makes 16 bars

Time

Prep time: 20 minutes
Cook time: 25 minutes
Cool time: 20 minutes
Total time: 1 hour 5 minutes

Ingredients

• 1 cup unsalted butter, softened
• 1 cup brown sugar, packed
• 1/2 cup granulated sugar
• 2 large eggs
• 2 tsp vanilla extract
• 2 cups all-purpose flour
• 1 1/2 cups crushed graham crackers (about 12 full sheets)
• 1 tsp baking soda
• 1/2 tsp salt
• 1 1/2 cups semi-sweet chocolate chips
• 1 (7 oz) jar marshmallow creme

Instructions

1. Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking dish with parchment paper.
2. In a large bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy.
3. Beat in the eggs one at a time, then mix in vanilla extract.
4. In a separate bowl, whisk together flour, crushed graham crackers, baking soda, and salt.
5. Gradually add the dry ingredients to the wet mixture until combined.
6. Press half the dough into the bottom of the prepared pan.
7. Sprinkle evenly with chocolate chips.
8. Carefully spread marshmallow creme over the chocolate layer. It’s sticky, so using greased fingers or a spatula helps.
9. Drop spoonfuls of the remaining dough on top and gently spread or pat down to cover.
10. Bake for 25 minutes, or until golden brown on top.
11. Let cool in the pan for at least 20 minutes before cutting into bars.

Tips

• Use parchment paper to make it easier to lift and slice cleanly.
• If marshmallow creme is too sticky to spread, microwave it for 10 seconds to loosen it up.
• For neater layers, chill the dough for 10 minutes before assembling.
• Try dark chocolate chips for a more intense flavor.
