Creating the Heavenly Lemon Oreo Dessert can be a simple yet satisfying task. Follow these steps to ensure success:

1. Prepare the Base: In a bowl, combine the crushed Oreo cookies and melted butter. Mix until well combined.
2. Press into Pan: Press the Oreo mixture into the bottom of a 9×9 inch square dish to form a crust.
3. Make the Cream Cheese Layer: In a mixing bowl, beat the softened cream cheese until smooth. Gradually add powdered sugar, mixing until well blended.
4. Add Lemon Juice: Pour in the fresh lemon juice and vanilla extract, continuing to mix until fully incorporated and creamy.
5. Add Condensed Milk: Gently fold in the sweetened condensed milk, ensuring no lumps remain.
6. Prepare the Whipping Cream: In another bowl, whip the heavy cream until soft peaks form. Fold this whipped cream into the lemon mixture.
7. Layer the Filling: Pour the lemon filling over the Oreo crust, spreading it evenly.
8. Chill the Dessert: Cover and refrigerate for at least 4 hours, or until set. For best results, refrigerate overnight.
9. Garnish and Serve: Before serving, garnish with lemon zest if desired. Cut into squares and enjoy!

These straightforward steps will lead to a heavenly dessert that you’ll be proud to present.
