To get a creamy filling, mix cream cheese and heavy cream before adding granulated sugar, which helps break down the cream cheese, and confectioner's sugar, which will help thicken the mix. Adding vanilla extract and lemon juice can help dial down the richness of the sweeter ingredients and balance out the flavors if needed.
Preheat the oven to 325°F and prepare a 12-muffin pan with 12 muffin liners. Set aside. Mix the graham cracker crumbs with the melted butter in a small bowl and stir to combine. Then, place about 1 Tablespoon into each muffin tin. Press the crumbs down with the back of a spoon to level.
Preheat oven to 350°F. Melt butter and add crushed cookies. Form the cookie mixture into 1 inch balls and place them in your mini cheesecake pan. Use tamper to firmly press the ball in to the bottom of the pan. In bowl beat cream cheese, sugar, eggs, and vanilla until thoroughly mixed.
In a saucepan, add strawberries that are cut in half, add the sugar, and lemon juice, and mix over medium-high heat. Mix the cornstarch with water and add to the mixture, mixing constantly. Decrease the heat to medium-low and simmer for 20 minutes mixing occasionally. Set aside and let it cool.
Scrape the whipped cream into a second bowl, then combine the cream cheese, sugar, and vanilla and mix until completely smooth and creamy. Gently fold the whipped cream into the cream cheese mixture and stir until completely combined and creamy. Spoon the mixture into a piping bag (if you like) and pipe it into the cups.
