In Food Processor or Blender, place the Oreo Cookies (including the filling) and pulse until you have fine crumbs. Place the Crumbs in a bowl. Place the Butter in a bowl, and microwave for about 15 seconds, or until the Butter is melted. Pour the Butter over the crumbs, and stir well to coat the cookie crumbs.
Line the 6-inch Spring-form pan with Parchment Paper, and pour the crumbs into Pan. Using the back of a spoon, or your fingers if you prefer, press the crumbs evenly into the bottom of the pan, and smooth out to an even layer.
Open the packages of Peeps, and you'll find the rows of Peeps are attached, so leave them attached to each other, do not separate them. Place the Peeps against the side of the Spring-form pan, on top of the Crust, and line the whole pan with the Peeps.
Place the Pan in the Freezer.In the mixing bowl of a stand Mixer, place the softened Cream Cheese, and pour in the Eagle-brand Milk, or sweetened condensed Milk. Add the Vanilla, and blend on low until mixed. Scrape down the sides of the bowl, and mix until completely blended and smooth.
You may want to scrape the sides of the bowl a couple of times, to make sure all the cream cheese is well blended. Remove the mixing bowl from the mixer, and fold in the Mini Chocolate Chips, and the Orange Chips.
Remove the pan from the Freezer and pour the Cheesecake batter into the Pan, filling the pan with the batter. Place the pan back in the freezer for 24 hours.
When the Cheesecake has been in the freezer for 24 hours, check the cheesecake and make sure it is set, or firm to the touch.
