Preheat oven to 375 degrees and line a baking sheet with parchment paper.

Place the melted butter in a shallow dish, for dipping the crescent roll triangles.

In a shallow flat dish, mix cinnamon and sugar.

Open the crescent rolls and separate into individual triangles.

Dip one triangle into the melted butter, then coat with cinnamon sugar.

Lay the coated triangle on a flat surface; place two apple slices onto the wide end.

Gently roll the triangle into a crescent shape starting from the apple end.

Place the roll onto the prepared baking sheet and repeat with remaining triangles.

Bake for 10-13 minutes or until golden brown on the bottoms.

Allow to cool slightly before serving.
