Wash and dry 12 half-pint glass mason jars, lids and rings. Set aside.
Wash and thinly slice 12 strawberries and place in a bowl with one tablespoon of granulated sugar. Mix to combine, then store the strawberries in the refrigerator to macerate while you prepare the cheesecakes.
In a medium-sized mixing bowl, mix together the graham cracker crumbs, melted butter, cinnamon and brown sugar. Place 2½ tablespoons of crumbs into each mason jar and using a wooden muddler or small spoon, press down the crumbs to form a flat crust on the bottom of each jar. Set aside.
Using a hand or standing mixer, whisk together one pint of heavy whipping cream along with the corn starch and ⅓ cup of powdered sugar until thick and fluffy. Set aside.
In a separate bowl, mix the cream cheese along with one cup of powdered sugar and two teaspoons of vanilla until smooth. Fold 1½ cups of the whipped cream into the cream cheese mixture to make a nice airy batter.
Spoon ⅓ cup portions of the cream cheese batter into each mason jar and smooth evenly over the graham cracker crust. Top with a layer of strawberries then a dollop of the remaining whipped cream.
Eat the cheesecakes immediately, or seal and store the jars in the refrigerator to serve later. These cheesecakes will keep well for up to three days.
