To make a heart shape with the dough, unroll the cinnamon roll dough completely, then fold it in half lengthwise to the center. Roll the ends in a cricle facing inwad. Pinch the fold to form the heart shape.
Place the rolls on the baking sheet and place in the oven to bake for 15-18 minutes.
Once done, let them cool slightly.
While they are cooling, mix the icing.
Put 2 T of the icing into a separate bowl and color with the red food coloring.
Frost the cinnamon rolls.
Add the rest of the icing to a different bowl, and color with the green food coloring. Add the heart sprinkles.
