Preheat your oven to 350 degrees, and grease a round cake pan.
Place cinnamon rolls into the cake pan as shown.
Discard the cinnamon roll icing.
Pour heavy cream over top of the cinnamon rolls.
Bake according to the package directions, about 25 minutes.
Meanwhile, make your frosting.
In a large mixing bowl, beat together cream cheese and butter until fluffy.
Add powdered sugar and vanilla, and mix well to incorporate.
Add milk and a pinch of salt, and mix well again.
Add 4-5 drops of green gel food coloring, and mix until color is fully incorporated. Add additional food coloring until you reach your desired shade of green, if necessary.
Once cinnamon rolls have finished baking, allow them to cool.
Remove them from the pan, they should be somewhat triangle shaped.
Turn the triangle shapes upside down. From the top, long side, cut out a small triangle from the center, as shown. If needed, round off the corners to form your heart shapes.
Frost your cinnamon rolls with the green frosting and add a heart sprinkle.
Enjoy!
