Unroll two cinnamon rolls and place them next to one another in a straight line down the center of a 9" round pan. Allow any excess to curl over at the top.
Gently unroll and arrange the remaining cinnamon in swirls around the pan. Cut the final cinnamon roll in half so that there's an even amount on both sides.
It's ok if there's space as the cinnamon rolls will rise and fill in the spaces as they bake.
Bake per the package instructions (often at 350F for 23-27 minutes) until golden.
In a small bowl, stir together the caramel sauce and red food coloring.
Brush over the warm cinnamon rolls.
Notes
Use thick refrigerated cinnamon rolls for a thicker, domed cinnamon roll brain. The regular-sized variety produces a thinner pan of cinnamon rolls.
Testing for doneness: To test if your cinnamon rolls are done, use a toothpick to gently tug at the center. You want to be able to pull the center slightly up and have it look cooked through.
