Prepare the cookie dough.
Divide the dough in half.
Color one portion red and color the other portion green.
Use a rolling pin to flatten each portion of colored dough between two sheets of wax paper.
Place the flattened dough on top of each other, similar to a stack of paper.
Tip: Since you rolled out the dough between two sheets of wax paper, you can just flip one sheet of dough on top of the other.
Start rolling this stack of cookie dough from one end to the other end. Use the sheet of wax paper from the base to help you roll. Just make sure it doesn't roll into your dough.
Toss sprinkles all over the cookie roll and along the sides and roll it back and forth until sprinkles stick on.
Chill in the refrigerator for a few hours or overnight until firm.
Then, use a very sharp knife to cut even slices.
Place them on a cookie tray, lined with parchment paper.
Bake at 350 degrees F for 10-12 minutes or until edges are firm.
Allow them to cool down completely and enjoy!
