Prepare a 12-well muffin pan with 12 cupcake liners. Silicone liners are easy to remove and can be reused. Set aside.
Put the 1 3/4 cups graham cracker crumbs (12 rectangles or 28 squares) into a food processor and process until you have fine crumbs (unless you are using crumbs from a box). Alternatively, add them to a zip lock bag and use a rolling pin to bash them up into fine crumbs.
Add the melted 6 tablespoons unsalted butter to the food processor and process until combined. The cookie mixture should now look like damp sand. If using crumbs from a box, these can be mixed in a bowl.
Divide the crumb mixture between the 12 cupcake liners. Use the back of a spoon to compact it on the bottom of the liner. Set aside while you make the cheesecake filling.
Add 3/4 cups of the heavy whipping cream to a mixing bowl. (Put the remaining heavy whipping cream back into the refrigerator to use as topping for the mini cheesecakes later.) Using a hand whisk or the whisk attachment on an electric hand mix the heavy whipping cream to stiff peaks.
In a separate bowl, beat together the softened 1 1/2 cups cream cheese, 1 cup powdered sugar and 1 teaspoon vanilla extract until smooth.
Fold the whipped cream into the cream cheese mixture using a hand spatula.
Add the 1/2 cup rainbow sprinkles and gently fold them into the cheesecake mixture.
Divide the cheesecake mixture between the cupcake liners. Use the back of a spoon to level it.
Cover the muffin tin with plastic wrap and place it into the freezer for 60 minutes.
When the mini cheesecakes have set, remove them from the freezer.
Add the remaining 1 cup of heavy whipping cream to a bowl and whisk it to soft peaks. Transfer the whipped cream to a piping bag fitted with a star nozzle. Pipe swirls on top of each mini cheesecake and add sprinkles to decorate.
