How to Make S’more Nut Bars

These come together quickly and bake beautifully.

Step 1: Preheat and Prepare

Preheat oven to 350°F (175°C). Line a 9×9-inch baking pan with parchment paper or lightly grease it.

Step 2: Make the Crust

In a mixing bowl, combine graham cracker crumbs, flour, brown sugar, and melted butter. Stir until crumbly but evenly moistened.

Press mixture firmly into the bottom of the prepared pan.

Bake for 8–10 minutes until lightly golden.

Step 3: Add the Layers

Remove crust from oven. Sprinkle chocolate chips evenly over the hot crust. The heat will start to melt them slightly.

Add chopped nuts over the chocolate layer.

Top generously with mini marshmallows.

Step 4: Bake Again

Return pan to oven and bake for 10–12 minutes, until marshmallows are puffed and lightly golden.

Watch closely during the last few minutes — you want that beautiful toasted top without burning.

The sight of those golden marshmallows bubbling? Pure magic!!

Step 5: Cool and Slice

Allow bars to cool completely before slicing. This helps them set and keeps the layers intact.

For clean cuts, use a sharp knife and wipe between slices.
