Preheat oven to 325° F. Place 18 cupcake-size muffin liners in two muffin pans. Spray the liners lightly with cooking spray.
For crust: In a small bowl, stir together graham cracker crumbs, sugar and melted butter, then press about 1 Tablespoon of mixture firmly into the bottom of each liner. Set aside.
For filling: Using an electric mixer, beat the cream cheese and sour cream until smooth and creamy. Add the eggs, one at a time, beating well after each addition. Add the sugar, lime zest, lime juice, cornstarch and vanilla and beat until smooth.
Divide and pour the filling equally into the 18 prepared crusts (about a 1/4 cup of batter per cup). Bake until the edges are set and the centers slightly jiggle when you tap the pan, about 20 minutes. Let cool completely then cover and refrigerate for at least 2 hours before serving.
For Raspberry sauce: Place the thawed raspberries, sugar, lime zest, and water in a medium bowl. Stir and mash with a spoon until smooth. Chill for at least 1 hour before drizzling over the cheesecakes. Serve and enjoy!
Notes
