Preheat the oven to 350 degrees.
Unroll the pie dough and with a butter knife spread the butter all over the pie dough circle.
Sprinkle the sugar all over.
Sprinkle the cinnamon all over.
Cut the circle into quarters, then cut each quarter into three's to get 12 triangles.
Roll up the triangle starting from either the pointed end or the wide end, whichever you like. Moisten the ends of the roll up with a little water to be sure the dough sticks together and the roll up closes nicely.
Place the roll ups onto a greased or parchment-lined cookie sheet and prick the tops once with a fork.
8 .Bake at 350 degrees for about 15-20 minutes or until they are lightly browned. If your pie is baking at 400 or 425 degrees, you can also put these in with the pie at that temperature, just bake them for about 10 minutes, and watch them until they are lightly browned. Cool the roll ups on a wire rack. Store them covered on top of the counter.
