For the crust, process cookies until crumbs in a food processor. Melt butter and mix with cookie crumbs with a fork until completely combined. Press into bottom of 8-inch square baking dish that is lined with parchment paper or foil.
Bake crust in a 350 degree oven for about 8 minutes. Remove and cool while preparing cheesecake filling.
For filling, in a double boiler, heat heavy cream on low until warm. Add in chocolate chips and stir continuously until chips are melted. Set aside.
In a large mixing bowl, beat cream cheese with sugar and cornstarch until fluffy. Beat in the sour cream, vanilla and eggs. Slowly beat in the chocolate mixture.
Pour into prepared crust. Bake in a 300 degree oven for about 35 minutes. Turn oven off, and let cheesecake remain in oven an additional 20 minutes.
Remove and cool. Refrigerate for at least 3 hours. Cut into small bites before garnishing.
For the garnish, beat butter with powdered sugar, marshmallow cream, and heavy cream on high for about 3-4 minutes until fluffy. Put in a pastry bag and using a star tip (or french tip) pipe a small swirl on each bite. Top with one mini Oreo. Enjoy!
Notes
Use a double boiler for your white chocolate. If you don’t have a double boiler, you can use a glass or metal bowl positioned over a saucepan to create your own faux double boiler.
Pay attention so that you don’t overbeat the cream cheese mixture.
If you don’t have a food processor, use a plastic bag to crush Oreos. Place cookies in the resealable plastic bag, removing excess air. Crush cookies by using a rolling pin.
Unlike traditional vanilla cheesecake, these mini cheesecakes do not require a water bath. This makes this a great recipe to try for cheesecake beginners.
Top your mini cheesecake with the marshmallow frosting and a mini Oreo cookie. Or keep it bare for simplicity sake!
Swap out the Oreo Cookies for Nutter Butters or Mint Oreos for a unique twist.
