Below are step-by-step instructions to make basic Oreo Dessert Trays. You can switch ingredients to match specific recipes as needed.

1. Prepare the Base: Start with a layer of crushed Oreo cookies mixed with melted butter. Press this mixture into the bottom of a rectangular dish as the base layer.

2. Make the Cream Layer: Beat softened cream cheese with powdered sugar and vanilla extract in a separate bowl until smooth. Layer this mixture over the crushed Oreo base.

3. Add the Whipped Cream: Fold whipped cream into the cream cheese mixture and spread it evenly over the cream layer.

4. Melt the Chocolate: Melt chocolate chips in the microwave or a double boiler. Once melted, drizzle it over the whipped cream layer for added decadence.

5. Chill: Cover the dish with plastic wrap and refrigerate for at least 2 hours to allow the layers to set together.

6. Top It Off: Before serving, add crumbled Oreos or additional toppings like sprinkles or fruit for a finishing touch.

7. Slice and Serve: Cut into squares or rectangles for serving, ensuring each piece gets a taste of all the delightful layers.

By following these steps, you’re on your way to creating stunning Oreo Dessert Trays that taste as good as they look!
