Line the bottom of a 9 inch Spring form pan with Parchment paper and layer oatmeal cream pies on the bottom.
Cut several of the Oatmeal Creme Pies in half, and line the edge of the Spring-form pan on top of the second layer of pies in the bottom.
Mix the softened cream cheese until smooth and creamy.
Add the vanilla and lemon juice, and mix.
In a separate bowl, add half of the 3 ounce package of Instant cheesecake flavored pudding and 1/2 a cup of half n half, and mix until the pudding is smooth, and no longer grainy.
Add the additional 2 Tablespoons as needed, to make the pudding smooth.
When pudding is smooth and thick, add it to the mixing bowl, and blend until completely smooth with the cream cheese.
Add the powdered sugar a little at a time, and blend well after each addition.
Pour the cheesecake batter into the Spring-form pan on top of the Oatmeal Creme Pies.
Smooth the top, and place the Cheesecake in the freezer for 2 hours.
Remove from freezer and cover the cheesecake with waxed paper and aluminum foil, and place in the refrigerator for at least 12 hours.
When you're ready to serve, remove from the refrigerator and pipe large dollops of Buttercream frosting around the edge on top of the cheesecake.
Crumble the remainder of the Oatmeal Creme Pies in the center of the top of the cheesecake, and place large pieces of Oatmeal pies on the edges of each piece, wedged in the dollop of frosting.
Serve, and Enjoy!
