Preheat your oven to 325°F (160°C).
In a medium bowl, combine the Golden Oreo cookie crumbs and melted butter. Mix until the crumbs are evenly coated with butter.
Press the mixture firmly into the bottom of a 9-inch springform pan, creating an even crust.
Bake the crust in the preheated oven for 10 minutes. Remove and let it cool while you prepare the filling.
In a large mixing bowl, beat the softened cream cheese and sugar together until smooth and creamy.
Add the eggs, one at a time, beating well after each addition.
Mix in the sour cream and vanilla extract until well incorporated.
Gradually add the flour and milk, mixing until just combined. Be careful not to overmix.
Gently fold in the chunks of Little Debbie Christmas Tree Cakes into the cheesecake batter.
Pour the cheesecake filling over the prepared Golden Oreo crust in the springform pan. Smooth the top with a spatula to create an even layer.
Tap the pan on the counter a few times to release any air bubbles.
Bake the cheesecake in the preheated oven for 1 hour or until the center is set and the top is lightly browned.
Once baked, turn off the oven and crack the oven door open. Let the cheesecake cool in the oven for 1-2 hours.
Remove the cheesecake from the oven and refrigerate for at least 4 hours or overnight to chill and set completely.
Carefully run a knife around the edge of the springform pan before releasing the sides.
