Preheat your oven to 325°F (163°C). Line a muffin pan with cupcake liners.
Place one mini cinnamon roll at the bottom of each liner. Press gently to flatten.
In a large bowl, beat cream cheese until smooth. Add sugar and vanilla; mix well.
Add eggs one at a time, mixing after each. Stir in sour cream, heavy cream, and cinnamon.
Spoon the cheesecake mixture over the cinnamon rolls in the muffin cups.
Bake for 20–25 minutes, until the centers are set.
Cool completely, then refrigerate for at least 2 hours.
Top with whipped cream or drizzle with icing before serving.
