Preheat oven to 350°F. 

Lightly spray muffin tray with nonstick cooking spray and set aside.

Roll out each tube of dough into a rectangle and pinch the seams closed. 

Spread 2 tbsp. of butter over each sheet of dough.

In a small bowl, whisk together sugar and cinnamon.

Sprinkle 1/4 c. sugar mixture evenly over the buttered dough and press the mixture lightly into the dough. Set the remaining mixture aside.

Roll the dough into a tight log. Cut the log in half and then cut each half in half again so that you have four pieces from each log of dough.

With the layered side facing out, roll each section into a cinnamon roll shape and tuck in the end piece of dough. Place into the muffin tray.

Bake for 18-20 minutes or until golden brown. 

After removing from the oven, roll each cruffin in the remaining sugar mixture. 

Serve and enjoy.
