Use a 1-inch cookie scoop or a spoon to add a layer of cheesecake batter to each muffin tin (this should fill them about halfway).
Spoon 1-2 teaspoons of the cinnamon filling over the cheesecake layer.
Spoon a final layer of cheesecake batter over the cinnamon filling. Gently spread the cheesecake batter through the muffin tin to cover the cinnamon filling layer. Use up all of the cheesecake batter on this step.
Add another 1 teaspoon of cinnamon filling to the tops of mini cheesecakes. Use up all of the filling on this step.
Use a toothpick to swirl the cinnamon filling and cheesecake batter together in each mini cheesecake,
Bake them for 20-22 minutes or until the center is not jiggly.
Remove them from the oven and allow them to cool to room temperature. After they have cooled to room temperature, place them in the fridge for at least 4 hours to set.
