Using a ⅓ measuring cup, pour the cream cheese filling into your prepared mini mason jars.
Place a kitchen towel on your counter. Try to remove air bubbles from the filling by lightly tapping them on your kitchen towel.
Preheat oven to 325 degrees Fahrenheit.
Pour your hot water into your metal baking dish about a third way up about 1-2 inches.
Carefully place your filled mini mason jars into the hot water bath. Place into the oven.
Bake for 28-35 minutes.
Remove from oven and water bath.
Fully cool your mini mason jar cheesecakes for about an hour.
Place your storage lids on the mason jars and refrigerate for 4 hours or overnight is best.
Serve chilled. You can also serve it with your favorite toppings.
