Mix graham cracker crumbs, melted butter, and sugar until well combined.
Press the mixture firmly into the bottom of a springform pan to form the crust. Chill in fridge for 20 minutes.
In a large bowl, beat cream cheese until smooth. Add powdered sugar, vanilla, and lemon juice and mix well.
Fold in whipped topping gently, making sure it stays light and airy.
Spread the cream cheese mixture over the chilled crust evenly.
Spoon blueberry pie filling over the top and spread gently.
Cover and refrigerate at least 4 hours, preferably overnight, until set.
Slice and serve chilled. Try not to eat the whole thing in one sitting. (No judgment if you do!)
