Beat cream cheese until smooth, then add heavy cream, powdered sugar, and vanilla and whip to stiff peaks.

Fold in sliced strawberries.

Arrange a single layer of graham crackers in the bottom of a 9x13-inch pan.

Spread one-third of the cream mixture over crackers, then repeat layers two more times, ending with cream on top.

Top with additional sliced strawberries.

Cover and refrigerate overnight or at least 6 hours before slicing and serving.
