Preheat the oven at 350°F.
Lay the dough flat on a baking tray. Separate out the triangles.
Place a spoonful of apple filling on the wide end of each triangle. Sprinkle cinnamon on top of the filling.
Roll the crescents: Roll each triangle from the wide end toward the pointed end.
Arrange the crescents on a baking tray and sprinkle a little cinnamon powder over the top.
Bake the crescents for about 18 minutes, until golden brown and cooked through. Check them near the end to make sure they don’t overbake.
Remove from the oven and serve warm.
