To make mini cheesecakes, first, line mini muffin pans with paper liners, yielding approximately 36 servings. Place one mini Nilla wafer in each paper liner at the bottom to substitute graham crackers.
In a medium bowl, use an electric mixer to beat cream cheese and sugar. Gradually add milk and mix until smooth. Then, slowly add the pudding mix and beat for 2-3 minutes until the mixture is thick and smooth.
