Step 1

In a large mixing bowl, beat cream, powdered sugar, and vanilla just until stiff peaks form, about 7-9 minutes.

Step 2

In a 13x9 pan or 3-quart dish, add a single layer of Oreos. You may need to break your cookies in half to fit the sides depending on the size of your baking dish. Top with 1/2 of the whipped cream. Repeat layers, ending with whipped cream.

Step 3

Cover and refrigerate for at least 6 hours or until cookies are softened. For best results chill overnight. [See note for a quicker version].

Step 4

To serve, top with crushed cookies. Other options include chocolate chips, caramel, or nuts.
