Kitchen Equipment You’ll Need

- 9×13-inch baking pan
- Mixing bowls
- Whisk
- Rubber spatula
- Measuring cups and spoons
- Cooling rack
Step-by-Step Instructions
Step 1:
Preheat your oven to 350°F (175°C) and grease your baking pan. This is an important first step, as it ensures that your S’more Bars will come out easily once baked. While the oven heats up, you can gather and prepare the other ingredients.
Step 2:
In a mixing bowl, combine the melted butter, brown sugar, and granulated sugar until smooth. This mixture should have a glossy appearance. Make sure to mix well so that all the sugars are fully incorporated into the butter.
Step 3:
Add the large eggs and vanilla extract to the sugar mixture, mixing until everything is well combined. You want this mixture to blend seamlessly, which will help create a rich flavor in your S’more Bars.
Step 4:
In another bowl, whisk together the all-purpose flour, baking powder, and salt. This dry mix is crucial for giving your bars structure, so make sure to whisk thoroughly to evenly distribute the baking powder and salt.
Step 5:
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; you want a thick batter that holds together well without becoming tough.
Step 6:
Spread half of the batter into your prepared baking pan. Use a spatula or the back of a spoon to ensure it’s evenly distributed across the bottom of the pan. This will form a solid base for your delicious filling.
Step 7:
Sprinkle the graham cracker crumbs evenly over the batter in the pan. This layer not only adds flavor but also gives that classic S’mores texture we all love. Make sure to cover it well for an even taste throughout!
Step 8:
Now sprinkle chocolate chips and mini marshmallows on top of those graham cracker crumbs. This is where things start to get really exciting! The chocolate will melt beautifully while baking, creating gooey pockets of goodness.
Step 9:
Dollop the remaining batter over the filling and spread it gently to cover everything. Don’t worry about making it perfect; some bits peeking through will just add character to your bars!
Step 10:
Bake in your preheated oven for 20-25 minutes or until golden brown on top. Keep an eye on them as they bake; when they start turning that lovely golden color, you know they’re almost ready!
Step 11:
Once baked, remove from the oven and allow to cool in the pan for at least 10 minutes. This cooling time helps everything set properly so you can cut nice bars without them falling apart.
Step 12:
Cut into bars and serve warm or at room temperature. These treats are great either way—warm with melty chocolate and marshmallows or cooled for a firmer bite! Enjoy every delicious bite!
Tips & Tricks
- Use room temperature eggs: Eggs incorporate better into the batter when they’re at room temperature, resulting in a smoother texture and more even baking.
- Don’t overmix the batter: Overmixing can lead to dense bars; mix just until combined for a light and chewy texture that holds together perfectly.
- Spread batter gently: When dolloping the remaining batter over the filling, use a gentle touch to avoid disturbing the layers below — this keeps your s’more bars beautifully layered.
- Keep an eye on baking time: Ovens vary, so start checking for doneness a few minutes early — you want a golden brown top for that perfect balance of chewy and crispy.
- Let them cool before slicing: Allowing the bars to cool in the pan helps them set properly and makes cutting easier, ensuring neat, delicious squares without crumbling.
- Serve warm with ice cream: For an indulgent treat, serve warm S’more Bars with a scoop of vanilla ice cream — the contrast of warm and cold elevates the entire experience!
Optional Ingredients
- Cream Cheese: Swirl in softened cream cheese for a rich, tangy contrast that adds creaminess to each bite. Blend it with a bit of sugar for sweetness before folding it into the batter.
- Cayenne Pepper: A pinch of cayenne pepper can introduce a surprising kick, enhancing the overall flavor profile. Mix it into the dry ingredients for that subtle heat.
- Chopped Nuts (e.g., walnuts or pecans): Add a crunchy texture and nutty flavor by folding in chopped nuts. They provide a delightful contrast to the soft marshmallows and chocolate.
- Orange Zest: Incorporate fresh orange zest to bring a bright, citrusy note that beautifully balances the sweetness of the bars. Just a teaspoon will do wonders!
- Caramel Sauce: Drizzle warm caramel sauce over the top before serving for an indulgent touch that adds both sweetness and richness, making your S’more Bars even more decadent.
What to Pair with S’more Bars?
To complement the rich sweetness of S’more Bars, consider serving a fresh arugula salad drizzled with a light lemon vinaigrette. The peppery notes of arugula and the citrus tang from the dressing create a refreshing contrast to the gooey chocolate and marshmallow filling. This balance not only cleanses the palate but also adds a vibrant touch to your dessert table.
For those seeking heartier options, roasted sweet potatoes or buttery corn on the cob would make delightful comfort sides. The natural sweetness of these vegetables harmonizes beautifully with the flavors in S’more Bars, while their warm textures provide a satisfying contrast to the chewy marshmallows and crunchy graham cracker crumbs. Together, they create a well-rounded meal that feels cozy and indulgent.
Finally, pair your S’more Bars with a chilled glass of sparkling lemonade or iced chai tea. The effervescence of sparkling lemonade offers a zesty brightness that cuts through the richness of the bars, while iced chai tea brings warm spices such as cinnamon and cardamom that echo the comforting flavors of vanilla and brown sugar. These drink options infuse an inviting atmosphere, making your dessert experience even more delightful.
Variations and Substitutions
Coconut Oil instead of Butter: Swap out the unsalted butter for melted coconut oil to create a subtly tropical flavor in your S’more Bars. This variation not only adds a hint of coconut aroma but also makes the bars dairy-free, perfect for those with lactose intolerance.
Honey for Sugar: Replace the granulated sugar with an equal amount of honey for a naturally sweet twist. This substitution will impart a unique floral note and moisture, making your bars wonderfully chewy while slightly reducing the overall sweetness.
Almond Flour for All-Purpose Flour: For a gluten-free version, try using almond flour in place of all-purpose flour. This change will add a nutty flavor and a denser texture, making each bite rich and satisfying while accommodating those with gluten sensitivities.
Nut Butter Addition: Incorporate 1/2 cup of creamy peanut butter or almond butter into the batter for added richness and flavor. The nutty essence complements the chocolate and marshmallows beautifully, resulting in a more indulgent treat that appeals to nut lovers.
Dark Chocolate Chips Instead of Milk Chocolate: Opt for dark chocolate chips instead of milk chocolate chips to enhance the depth of flavor in your S’more Bars. The bittersweet chocolate balances perfectly with the sweetness of the marshmallows, creating a sophisticated dessert that caters to adult palates.
Spiced Graham Crackers for Extra Flavor: Use cinnamon or chocolate-flavored graham cracker crumbs instead of plain ones. This swap infuses your bars with an additional layer of spice or richness, elevating the classic S’mores experience to something extraordinary and deliciously different.
Mini Marshmallow Fluff instead of Mini Marshmallows: For a smoother texture, replace mini marshmallows with mini marshmallow fluff spread over the filling layer. This creates an ooey-gooey consistency that melds beautifully with the other ingredients, offering a delightful contrast to the firm base.
How to Store
To store your S’more Bars, allow them to cool completely in the pan before transferring them to an airtight container. They can be kept in the refrigerator for up to one week. When you’re ready to enjoy them again, simply reheat individual bars in the microwave for about 10-15 seconds, which will help restore their gooey texture and soften the chocolate and marshmallows.
S’more Bars can be frozen, but the texture may change slightly upon thawing due to the marshmallows. To freeze, cut the bars into portions and wrap each piece tightly in plastic wrap before placing them in a freezer-safe bag or container. They will stay fresh for up to three months. Thaw in the refrigerator overnight or at room temperature for a couple of hours, and reheat as needed for a warm treat.
Frequently Asked Questions
Can I use a different type of sugar in this recipe?
Yes, you can use coconut sugar or white sugar instead of brown sugar for a lighter flavor. However, using brown sugar adds moisture and a rich caramel taste that complements the S’more Bars beautifully.
Can I make these S’more Bars gluten-free?
Absolutely! You can substitute the all-purpose flour with a 1: 1 gluten-free flour blend. Just ensure that your graham cracker crumbs are also gluten-free to keep the entire recipe compliant.
How do I know when my S’more Bars are done baking?
The S’more Bars are ready when they turn golden brown around the edges and a toothpick inserted in the center comes out clean or with just a few moist crumbs. Keep an eye on them to prevent over-baking.

While chocolate chips are ideal for this recipe, feel free to use chopped chocolate bars or even peanut butter chips if you’re looking for a unique twist on the classic flavor combination.
