Oven-Baked S’Mores Ingredients For the Base Graham Crackers – provide structure and a crunchy texture; you can substitute with gluten-free graham crackers for dietary needs. Butter – adds richness and a silky mouthfeel; use vegan butter for a dairy-free version. Sugar – sweetens the “goo” mixture, enhancing the dessert’s flavor; consider using brown sugar for added richness. For Filling the Layers Chocolate – the star ingredient providing a deep, rich flavor; semi-sweet or dark chocolate works well based on your preference. Mini Marshmallows – bring a chewy texture and sweet surprise; substitute with marshmallow fluff for an ultra-gooey consistency. Step‑by‑Step Instructions for Oven-Baked S’Mores Step 1: Preheat the Oven Begin by preheating your oven to 350°F (175°C). This step is crucial for ensuring your layers of graham crackers and gooey marshmallows reach that perfect melty consistency. Set a solid baking pan aside, as you will need it ready to create your oven-baked s’mores masterpiece. Step 2: Prepare the Baking Pan Line a 9×9-inch baking pan with parchment paper, allowing some edges to overhang—this makes for easier removal later. Gently press the parchment into the corners to avoid air pockets. Use a pair of kitchen scissors if necessary to trim any excess. With a prepared pan, you are one step closer to enjoying your oven-baked s’mores. Step 3: Create the Gooey Base In a medium saucepan, melt ½ cup of butter over low heat. Once fully melted, stir in ½ cup of sugar until fully combined and slightly bubbly. This mixture will create a rich gooey base for your oven-baked s’mores. Once the sugary mix is smooth, remove it from heat and let it cool briefly while you prepare the layers. Step 4: Layer the Graham Crackers Spread a single layer of graham crackers in the bottom of your prepared baking pan, ensuring they cover the entire base. Depending on the size of your crackers, you may need to break some into pieces to create a snug fit. Spoon half of the gooey butter-sugar mixture evenly over the crackers, saturating them for that deliciously chewy texture. Step 5: Add Chocolate and Marshmallows Evenly distribute your favorite chocolate—squares or chips—over the buttery graham crackers. Next, add a generous handful of mini marshmallows on top of the chocolate. This layer is where the magic of oven-baked s’mores begins to come together, creating that decadent blend of flavors and textures that everyone loves. Step 6: Repeat the Layers For the second layer, repeat by adding another layer of graham crackers over the chocolate and marshmallows. Drizzle the remaining goo mixture generously on top. This ensures all the layers meld beautifully during baking. Finish off by adding another layer of chocolate and a final sprinkle of mini marshmallows for that beautifully golden topping. Step 7: Bake to Golden Perfection Place the pan in your preheated oven and bake for about 20 minutes, or until the top is golden brown and bubbly. You’ll know it’s done when the marshmallows are puffy and lightly toasted, releasing that irresistible scent of sweet goodness. Keep a close eye on them to prevent over-baking, which can lead to a hard texture. Step 8: Cool and Serve Once out of the oven, allow your oven-baked s’mores to cool in the pan for about 10 minutes. This cooling period helps the bars set up slightly, making slicing easier. For a gooey treat, feel free to dig in while still warm; if you prefer clean cuts, wait a little longer before slicing into squares and serving. How to Store and Freeze Oven-Baked S’Mores Room Temperature: Store leftover oven-baked s’mores in an airtight container at room temperature for up to 3 days to maintain their gooey texture. Fridge: For longer freshness, you can refrigerate them in an airtight container, where they will stay delicious for up to a week. Freezer: If you want to enjoy these treats later, wrap them tightly in plastic wrap and then place in a freezer-safe bag. They can be frozen for up to 3 months. Reheating: To reheat, simply warm them in the oven at 350°F (175°C) for about 10 minutes or until heated through, restoring that delightful gooeyness. Helpful Tricks for Oven-Baked S’Mores Cool Before Cutting: Let the bars cool for about 10 minutes; this helps them set and makes for cleaner slices. If you dive in too soon, they may fall apart. Watch the Bake Time: Stay close while baking to avoid over-baking, which can harden your bars. Look for a golden-brown top and puffy marshmallows for perfect oven-baked s’mores. Layer Smartly: Ensure even layering of graham crackers, chocolate, and marshmallows to achieve that delightful gooey texture. Uneven layers can lead to dry spots. Substitutions Matter: Feel free to experiment with chocolate types and other mix-ins, but be mindful of how these changes may affect the taste of your oven-baked s’mores. Serving Suggestions: For a cozy experience, serve warm with a scoop of ice cream or a drizzle of chocolate sauce on top, adding an extra layer of indulgence. What to Serve with Easy Oven-Baked S’mores Bars? Warm, indulgent flavors and gooey textures create a perfect backdrop for a delightful spread that will elevate your dessert experience. Fresh Berries: Juicy strawberries or raspberries add a refreshing contrast, balancing the sweetness of the s’mores with their tartness. Vanilla Ice Cream: A scoop of creamy vanilla ice cream melts beautifully over the warm bars, enhancing the gooey sensation and bringing a comforting chill. Chocolate Drizzle: A simple drizzle of melted chocolate or a rich chocolate sauce deepens the chocolate notes, creating an even more decadent treat to savor. Grilled Peaches: Sweet, caramelized peaches bring a lovely fruity warmth that complements the textures of the s’mores, adding a Southern touch to your gathering. Nutty Granola: A sprinkle of crunchy granola offers added texture and a nutty flavor that harmonizes with the flavors in the s’mores. Mint Tea: A warm cup of mint tea refreshes the palate, making it a delightful drink option that pairs elegantly with the rich oven-baked s’mores. Coffee: A robust cup of coffee balances the sweetness beautifully, making it a perfect pairing for late-night gatherings with friends. Make Ahead Options These Oven-Baked S’mores Bars are perfect for meal prep, allowing you to save time for your busy weeknights. You can assemble the layers up to 24 hours in advance, covering them tightly with plastic wrap and refrigerating to maintain their freshness.
