Open the cinnamon roll tube and separate out the icing and the rolls.
Unroll your first roll and shape into a tree by starting at the base of the tree and making a 2-2.5" line of dough and then curving it up to make the next row slightly smaller, and repeating until your dough is gone.
Bake as directed on the package.
While the rolls bake, mix the food coloring into the icing.
Remove the cinnamon rolls from the oven once they are done and let cool 3-5 minutes.
Spread the green icing evenly over the top each row then sprinkle with the sprinkles then place the yellow M&M on top.
