Preheat oven to 350 degrees.
Line 48 cups in mini muffin tins with mini cupcake liners.
Put 1 vanilla wafer into each cupcake liner.
Beat cream cheese until light and fluffy. Add in eggs, sugar, vanilla extract, and lemon juice together until smooth and creamy. Be sure to scrape down sides and then beat well again.
Using a mini cookie scoop or a 1/2 tablespoon measuring spoon, portion out batter evenly among the 48 muffin cups.
Bake for 12-15 minutes or until cheesecakes sides puff up and center is still a TINY bit jiggly, being careful to not over bake.
Let cheesecakes cool for 10 minutes in pan.
Remove from pan and cool for another 10-20 minutes on a cooling rack.
Place in sealed container and store in fridge for at least 2 hours, or until completely chilled, before serving.
