Begin by crushing 36 Oreo cookies in a food processor until fine crumbs form. In a mixing bowl, combine the crushed Oreos with ¼ cup melted unsalted butter until well coated. Press this mixture firmly into the bottom of an 8 or 9-inch springform pan, creating an even layer. Chill the crust in the refrigerator for 15 minutes to set and firm up.

As the crust chills, take a large mixing bowl and chill it in the freezer for about 10 minutes. Then, add 2 cups of heavy whipping cream, ½ cup powdered sugar, and 1 teaspoon vanilla extract to the bowl. Using an electric mixer, whip the mixture on medium-high speed until stiff peaks form, which should take about 3-5 minutes. Be careful not to over-beat, as you want it fluffy and smooth for the No-Bake Oreo Cake.

In another bowl, use an electric mixer to beat 8 ounces of softened cream cheese until it’s smooth and creamy, which takes about 2 minutes. Gradually pour in ½ cup sweetened condensed milk, mixing on low speed to combine until fluffy. Afterwards, gently fold in the prepared whipped cream in batches, ensuring the mixture stays light and airy for the filling.

Now it's time to add some texture to the filling. Carefully fold 1 cup of crushed Oreos into the creamy mixture, making sure to distribute them evenly without deflating the whipped cream. This incorporation of cookie bits will elevate the creamy filling, making your No-Bake Oreo Cake irresistibly delicious!

Retrieve your chilled crust and pour the creamy filling over the top, smoothing it out with a spatula for an even layer. Tap the pan gently on the counter to remove any air bubbles trapped in the filling. Cover the springform pan with plastic wrap and let it chill in the refrigerator for at least 4 hours or overnight for best results.

Once fully set, carefully run a sharp knife around the edges of the springform pan before releasing the side. For a festive touch, decorate the No-Bake Oreo Cake with ½ cup of mini Oreos on top. To cut, dip a knife in hot water and wipe it dry, ensuring clean, beautiful slices for serving your guests!
