Now that you have your ingredients ready, let’s dive into the magic of baking these delightful S'mores Brownies!
Step‑by‑Step Instructions for S'mores Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This critical step ensures that your S’mores Brownies will bake evenly and perfectly. While the oven heats up, gather your ingredients and equipment, including a large mixing bowl and a greased 13×9-inch baking pan, to streamline the baking process.
Step 2: Prepare the Brownie Batter
In your mixing bowl, combine the boxed brownie mix, eggs, oil, and water according to the package instructions for “cakey” brownies. Whisk the mixture until it's just blended—avoid over-mixing, as this can toughen the brownies. You should see a smooth and slightly thick batter ready to turn into a gooey base that’s perfect for your S’mores Brownies.
Step 3: Pour and Spread the Batter
Pour the brownie batter into your greased baking pan, spreading it out evenly using a spatula. This step helps to ensure every bite has that rich brownie goodness. As you smooth the top, keep an eye out for any air bubbles, gently popping them to create a lovely, burbling texture throughout your S’mores Brownies.
Step 4: Bake the Brownies
Place the pan in the preheated oven and bake the brownies for about 20 minutes. The edges should look set, while the center remains slightly underbaked, giving you that perfect fudgy texture. To check if they're ready, insert a toothpick—if it comes out with a few moist crumbs, you’re good to go!
Step 5: Add Toppings
Once the brownies are done baking, carefully remove them from the oven. Top the slightly underbaked brownies with scattered graham cracker pieces, then follow with a mound of mini marshmallows. Finally, place the chocolate bar squares on top, layering them for that decadent finish that truly embodies S’mores Brownies.
Step 6: Final Bake
Return the baking pan to the oven and bake for an additional 5 minutes. During this time, you'll want to keep an eye on the marshmallows; they should puff up and turn a lovely golden color. This final bake creates a magical topping that perfectly complements the rich brownie base below.
Step 7: Cool and Slice
After removing the brownies from the oven, let them cool for a few minutes. For cleaner cuts, you can allow them to cool completely before slicing. When ready, use a sharp knife (sprayed with cooking spray for ease) to cut generous squares of your S’mores Brownies, revealing the luscious layers within!

Expert Tips for S'mores Brownies
-
Check Your Oven: Ensure your oven is properly calibrated; an inaccurate temperature can lead to underbaked or overbaked brownies.
-
Avoid Overmixing: Mix the batter just until combined to maintain that gooey texture. Overmixing can make the brownies tough!
-
Layering Strategy: Press graham cracker pieces gently into the batter to prevent them from sinking too much during baking for the perfect S'mores Brownies experience.
-
Perfectly Cut Brownies: Let the brownies cool completely for cleaner cuts. Use a plastic knife or spray a regular knife with cooking spray for effortless slicing.
-
Store for Freshness: Store any leftovers in an airtight container at room temperature for up to 3 days to keep the brownies fresh and delightful!
How to Store and Freeze S'mores Brownies
Room Temperature: Store leftover S'mores Brownies in an airtight container at room temperature for up to 3 days. This keeps them soft and gooey, ready for midnight snacking!
Freezer: For longer storage, freeze individual brownie squares wrapped tightly in plastic wrap and then aluminum foil. They’ll stay fresh for up to 2 months. Just thaw at room temperature before serving.
Reheating: To enjoy them warm, pop the brownies in a microwave for about 10-15 seconds. This makes the marshmallows gooey again, bringing that fresh-baked taste back to life!

S'mores Brownies Recipe FAQs
How do I choose the right ingredients for S'mores Brownies?
Absolutely! When selecting your ingredients, look for boxed brownie mix with a simple list for the best results. Fresh eggs are key for structure, while high-quality chocolate bars enhance flavor. For the graham crackers, ensure they’re crunchy without dark spots to maintain texture. As for marshmallows, mini ones are perfect for the topping; if using larger ones, cut them into smaller pieces for uniform melting.
What’s the best way to store S'mores Brownies?
Very simple! Keep your leftover S'mores Brownies covered in an airtight container at room temperature for up to 3 days. This way, they maintain their gooey goodness! For longer storage, wrap individual squares tightly in plastic wrap followed by aluminum foil, and freeze for up to 2 months. They’ll be just as delicious when thawed at room temperature.
Can I freeze S'mores Brownies?
Of course! To freeze your S'mores Brownies, first, let them cool completely. Then, slice them into squares, wrap each piece tightly in plastic wrap, and place them in a freezer-safe bag or container. They can last up to 2 months in the freezer. When you’re ready to indulge, simply thaw them at room temperature. For that freshly-baked taste, you can pop them in the microwave for 10-15 seconds!
What if my brownies are dry or crumbly?
Oh no! If your brownies turn out dry, it may be due to overbaking. Remember, you want to remove them from the oven when a few moist crumbs cling to the toothpick. If they do seem dry after baking, consider adding a scoop of vanilla ice cream on top for a delicious remedy. Also, don’t hesitate to slightly underbake the next batch; that’s where the magic happens for the gooey texture!
Are there any allergy considerations for S'mores Brownies?
Absolutely! If you’re catering to particular allergies, check your boxed brownie mix for any potential allergens. Common components include eggs and gluten. For a vegan twist, replace eggs with flaxseed meal mixed with water (1 tablespoon of flaxseed meal + 2.5 tablespoon water equals one egg). For gluten-free options, use gluten-free graham crackers and a gluten-free brownie mix. It’s all about enjoying these delicious S'mores Brownies safely!
