Key Ingredients in S’mores Bars
- Graham Cracker Crumbs – These form the buttery, golden crust and mimic that signature s’mores crunch.
- Melted Butter – Helps bind the crust and gives it rich flavor and structure.
- Hershey’s Milk Chocolate Bars – Extra-large bars melt smoothly and bring that classic s’mores taste.
- Mini Marshmallows – Toasted on top for a gooey, golden finish that screams campfire comfort.
How to Make S’mores Bars
Foolproof Steps for Perfect S’mores Bars
- Prep the Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch pan with foil and lightly spray it with nonstick cooking spray. - Make the Crust
Mix graham cracker crumbs with ½ cup melted butter. If it feels too dry, add 1–2 tablespoons more butter. Press the mixture evenly into the pan. - Bake the Crust
Bake for 8–10 minutes, just until the edges turn lightly golden. Then, turn off the oven. - Layer the Chocolate
Arrange the Hershey’s bars over the warm crust. Return to the warm (but off) oven for 1 minute to melt slightly. - Add the Marshmallows
Nestle mini marshmallows neatly on top of the melted chocolate, covering it completely. - Broil to Toast
Broil for 1–2 minutes until the marshmallows are golden brown. Keep a close watch—marshmallows toast quickly! - Cool & Set
Let the bars cool fully. For quicker setting, cool on the counter for 15 minutes, then chill in the fridge before slicing. - Slice Cleanly
Use a sharp knife for perfect squares. Wipe the blade between cuts for neat edges.
S’mores Bars Tips and Twists
Tips for Success
- Line your pan with foil for easy lifting and cleanup.
- Add a touch more butter if the crust seems dry—it should feel like damp sand.
- Always watch the broiler closely—marshmallows can burn in seconds.
- Chill the bars before slicing to keep the layers intact.
- Use a hot knife (dipped in warm water) for smooth cuts.
Easy Twists
- Peanut Butter: Swirl peanut butter into the melted chocolate before adding marshmallows.
- Nutty Crunch: Sprinkle crushed peanuts or almonds before the marshmallows go on.
- Cookie Swap: Use crushed Oreos or chocolate chip cookies instead of graham crackers.
Storage, Reheating, and Make-Ahead Tips
How to Keep Your S’mores Bars Delicious
- Storage: Store in an airtight container at room temp for 3–4 days or in the fridge for up to a week.
- Reheating: Warm individual bars in the microwave for 8–10 seconds to revive that gooey magic.
- Make-Ahead: Bake and cool a day before serving. They hold up great and slice even better after chilling.
