How To Make S’mores Bars
Step 1: Prep The Pan
Preheat your oven to 350°F.
Line a 9×13 baking dish with parchment paper or lightly grease the pan.
Step 2: Make The Graham Cracker Crust
In a mixing bowl, stir together the graham cracker crumbs and melted butter until the crumbs look evenly coated.
Press the mixture firmly into the bottom of the baking pan to create an even crust.
Bake for 8 minutes.
Step 3: Add The Chocolate
Remove the crust from the oven and immediately sprinkle the chocolate chips evenly over the warm crust.
Let them sit for about a minute so they begin to soften.
Step 4: Add Marshmallows
Scatter the mini marshmallows over the chocolate layer.
Return the pan to the oven and bake for 15–20 minutes, or until the marshmallows are golden brown and toasted on top.
Step 5: Cool Before Slicing
Let the bars cool completely before cutting.
For cleaner slices, chill the pan in the fridge for 20–30 minutes first.
Tips For The Best S’mores Bars
Don’t Skip Cooling
The chocolate layer needs time to set slightly before slicing. Warm bars are delicious, but messy.
Use Good Chocolate
Semi-sweet chocolate balances the sweetness of the marshmallows really well, but milk chocolate works too if you want a more classic s’mores flavor.
Watch The Marshmallows Carefully
Marshmallows go from golden to burnt fast. Keep an eye on the oven during the last few minutes.
Storage
Store leftover bars in an airtight container at room temperature for up to 3 days.
You can refrigerate them if your kitchen is warm, but let them come to room temperature before serving for the best texture.
