Preheat oven to 350ºF. Line each muffin tin with a cupcake liner. Place one Oreo cookie in the bottom of each cupcake liner.
In a mixing bowl with beaters, blend together cream cheese, Greek yogurt and sugar until thoroughly combined. Add in vanilla and mix.
Add in eggs, one at a time until blended.
Using cookie scooper or spoon, scoop cream cheese mixture into the muffin tin, over the Oreo in the bottom.
Place in oven and bake for 20 minutes. Pull out of oven and place muffin tin on a cookie rack to cool.
When cool, lightly take out of muffin tin and peel away the liner. Enjoy!
