Preheat your oven to 375 degrees F. Meanwhile, pop open those rolls of cinnamon rolls and arrange them in a heart shape on your pan. I used 12 around the edges and squished the last 4 into the middle. I also flattened a few of the edges and made a little bit of a point on the roll on the bottom of the heart. Then stick those puppies in the oven. I cooked mine for about 22 minutes to make sure the middle rolls were done, but things cook differently everywhere, so keep an eye on them.
While the cinnamon rolls are cooking, dye the included icing pink or red. I just added two drops of food coloring to each pot of frosting and mixed it up.
When the cinnamon rolls are done, give them one minute to cool, then spread that frosting right on with a knife and let your little ones help you add some festive Valentine's sprinkles.
