Preheat the Oven:
Preheat your oven to 350°F (177°C). Line a 12-count muffin pan with cupcake liners.
Make the Cheesecake Filling:
In a large mixing bowl, beat the cream cheese on low speed until smooth.
Add the granulated sugar and beat on low for about 2 minutes, until the mixture becomes smooth.
Beat in the sour cream and vanilla extract until well combined and smooth.
With the mixer on low, add the eggs one at a time, beating well after each addition. Scrape the sides and bottom of the bowl as needed. Be careful not to overmix after adding the eggs.
Gently fold in the crushed Oreo cookies by hand.
Prepare the Muffin Pan:
Place one whole Oreo cookie at the bottom of each cupcake liner.
Fill each cupcake well with the cheesecake filling.
Bake:
Bake the mini Oreo cheesecakes for 14-16 minutes, or until the centers are set but still slightly jiggly.
Cool:
Remove the muffin pan from the oven and place it on a cooling rack. Let it cool for 1 hour.
Loosely cover the pan with plastic wrap and transfer the cheesecakes to the fridge. Chill for at least 6 hours to set.
Make the Topping:
In a small mixing bowl, stir together the sour cream, sugar, and vanilla extract until smooth.
Serve:
Before serving, top each mini Oreo cheesecake with a dollop of the sweetened sour cream mixture and a sprinkle of crushed Oreo cookies.
Enjoy!
