In a large mixing bowl, beat cream cheese until smooth.
Add sugar and vanilla extract. Mix until well combined.
Fold in half of the whipped topping. Spread this mixture into the graham cracker crust.
In a separate bowl, dissolve the strawberry gelatin in boiling water. Stir until fully dissolved.
Chill gelatin mixture in the fridge for 10-15 minutes, or until it begins to thicken slightly.
Stir sliced strawberries into the gelatin mixture. Pour this over the cream cheese layer in the crust.
Refrigerate for at least 4 hours or until fully set.
Top with the remaining whipped topping before serving.
