Open your package of cinnamon rolls with a spoon or wack the edge on the counter after peeling off the first layer of paper.
Spray your pan with oil, then add cinnamon rolls to the pan.
Add your heavy whipping cream to the bottom of the pan. Make sure there's a layer of the cream sitting at the bottom of the pan so the cinnamon rolls are sitting in it.
Melt butter in microwave, then combine butter, brown sugar and cinnamon.
Top your cinnamon rolls with the butter, brown sugar and cinnamon mixture.
Cover pan with foil.
Bake in over at 350° for 35-40 minutes. The exact time will vary with your oven, so keep an eye on them after that 30 minute mark.
