Add powdered sugar and vanilla extract; continue beating until fluffy.
In a separate bowl, beat cream cheese until smooth.
Gently fold the whipped cream into the cream cheese until fully combined.
In a 9x13-inch baking dish, place a layer of graham crackers on the bottom.
Spread part of the cream mixture over the crackers.
Add a layer of sliced strawberries.
Repeat layers until all ingredients are used, finishing with cream and strawberries on top.
Cover and refrigerate for at least 6 hours or overnight before serving.
