- Preheat the oven to 350°F. Line a muffin tin with paper liners. 
- In a medium bowl, whisk together the flour, baking soda, and salt. 
- In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Add the egg and vanilla extract, mixing until well combined. 
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Stir in the Oreo cookie crumbs. 
- Scoop about 1 tablespoon of the cookie dough into each muffin cup, pressing it down slightly to form a base. Bake for 10-12 minutes, or until the edges are golden. Remove from the oven and let cool completely. 
- In a separate bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until well combined. Gently fold in the whipped cream until fully incorporated. 
- Once the cookie cups are cool, spoon the cheesecake filling into each cup, smoothing the tops. Chill in the refrigerator for at least 1 hour before serving. 
- Serve chilled, topped with mini Oreo cookies if desired.
