Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan or line it with parchment paper.
Open the can of cinnamon rolls and press them into the bottom of the pan to form a crust, sealing the seams together.
In a bowl, beat softened cream cheese and sugar together until smooth and fluffy.
Mix in the sour cream, vanilla, and eggs one at a time. Pour this luscious mixture over the cinnamon roll base.
In a small bowl, mix brown sugar and cinnamon. Sprinkle evenly over the top of the cheesecake.
Bake for 40–45 minutes until the edges are set and the center jiggles just slightly.
Let it cool for an hour, then chill in the fridge for at least 4 hours (overnight is better).
Drizzle with the cinnamon roll icing before serving. Don’t skip this part—it’s magic.
