Count out 100 mini cupcake liners and place them in mini cupcake tins.
Crush the Oreos including the creme filling, into fine, crumbly crumbs.
Measure 1 teaspoon of Oreo crumbs into each of the 100 cupcake liners. If you have remaining crumbs, just divide them up among the cupcake liners.
Press down the Oreo crumbs with your fingertips.
Preheat your oven to 300 degrees.
In a mixing bowl, beat the cream cheese, sweetened condensed milk, and vanilla until completely blended and smooth.
Melt the chocolate chips and beat into the cream cheese mixture.
Beat in the eggs just until combined and smooth. Don't overbeat in the eggs, or your filling will puff up too high and fall in.
Scoop the cheesecake filling into the Oreo-crusted cupcake liners and fill them right to the tops of the liners.
Bake at 300 degrees for 15 minutes. I usually bake these in 2 batches. Cool to room temperature and then chill for 2 hours before serving. Sprinkle with chocolate jimmies for a dressed-up look if you desire.
