No campfire needed for these S'mores Brownies. With just three extra ingredients: marshmallows, chocolate, and graham crackers, you can transform a box of Betty Crocker™ Supreme Original Brownie Mix into S'mores Brownies with a twist. This S'mores Brownies recipe is super easy; just top your brownies with mini marshmallows and graham crackers before placing under the broiler until everything is golden brown and toasty. Now for our favorite part, sprinkle with Hershey’s milk chocolate squares and enjoy an ooey, gooey S'mores Brownie. Your kids will love this recipe.

Recipe Ingredients

Below are the ingredients needed for these S'mores Brownies.

Brownie Mix: This is the base of the recipe, providing the fundamental brownie flavor and texture.

Miniature Marshmallows: Marshmallows are a classic component of s'mores, adding a sweet, gooey texture and flavor that complements the chocolate and graham crackers.

Graham Cracker Squares: Graham crackers provide a crunchy texture and a hint of honey flavor, which are characteristic of s'mores. They add structural contrast to the soft brownies and melted marshmallows.

Milk Chocolate Candy Bars: Milk chocolate is another key element of s'mores, offering a rich, sweet, and creamy flavor that ties all the components together.

Other Ingredients You’ll Need: Water, vegetable oil, eggs.

Storage

To properly store your S'mores Brownies and maintain their deliciousness, here are some tips.

Room Temperature

If you plan to eat the brownies within 1-2 days, place the cooled brownies in an airtight container away from direct sunlight.

Refrigerator 

For longer storage (3-4 days), refrigerate the brownies. Be aware that refrigeration can slightly dry them out, so be sure the container is well-sealed.  

Freezing 

For even longer storage (up to 3 months), you can freeze the brownies. Wrap them individually in plastic wrap, then place them in a freezer-safe bag or container. Thaw at room temperature before serving.

Reheating   

Place brownies on a microwavable plate and heat on medium (50%) for 10-15 seconds to bring back that gooey texture.
