Mix warm milk, yeast and sugar. Let it sit until foamy and active. Add butter, salt and flour. Mix until soft dough forms.

Place dough on floured board. Knead gently for eight minutes. Dough should feel smooth and stretchy. Let it rest and rise until doubled.

Roll dough into a large rectangle shape. Keep even thickness across surface. This helps filling spread well and bake evenly every time.

Spread melted butter over dough surface. Sprinkle marshmallows, chocolate chips, and crushed graham crackers evenly. Leave small border along edges.

Roll dough from long side into log. Cut even slices with knife. Place rolls in greased baking dish close together.

Cover dish loosely with towel. Let rolls rise again until puffy and light. This makes them very soft when baked.

Preheat oven and bake rolls until golden brown. Watch marshmallows melt and bubble gently. Remove from oven and cool slightly before serving.

Drizzle melted chocolate on top if desired. Add few mini marshmallows for pretty look. Serve warm for best soft texture.
