Preheat the oven to 350F.
Line a muffin tin with paper liners.
In a bowl, combine the finely crushed graham crackers with granulated sugar. Then, stir in the melted butter. Divide between 24 paper liners. Press firmly with the back of the spoon to create the crust. Set aside.
In a mixing bowl, beat together the softened cream cheese, granulated sugar, and all-purpose flour using an electric mixer. Add eggs, one at a time. Then, beat in vanilla extract and sour cream. Don’t over-mix, beat just until combined.
Divide the cream cheese filling between the 24 paper liners. Each liner has to be about ⅔ full. Bake for 15-20 minutes. The New York cheesecake cupcakes should jiggle a little in the middle when done.
Remove from the oven and sprinkle with crushed graham crackers. Let cool to room temperature.
Prepare the frosting. In a bowl, beat together the cream cheese, softened butter, and powdered sugar. Transfer to a piping bag and decorate these easy cheesecake cupcakes. Enjoy!
