Preheat the oven to 350°
Mix together the graham crackers, melted butter and sugar. Add cupcake liners to a muffin tin and evenly distribute about 1-1.5 Tbs of graham cracker crust into each one.
Using the bottom flat part of a cup, press down to spread the crust out evenly and compress it. Place the muffin tin into the center rack of the oven for 5 minutes to toast up a bit.
In the meantime, in a large bowl, add the softened cream cheese and mix each ingredient in separately starting with the sugar. Then mix in the eggs. vanilla, lemon juice, flour and sour cream.
Evenly distribute the cheesecake filling on top of the crusts. You’ll have a lot of filling left, so expect to make a second batch.
Place the muffin tin into the center rack of the oven for 15-20 minutes. It’s ok if the center is a little jiggly.
Allow the mini cheesecakes to cool to room temperature before lightly covering them with plastic wrap and placing them in the fridge for at least 4 hours and up to overnight.
Once you’re ready to serve them, remove them from the cupcake liners and add about 1 teaspoon of blueberry pie filling on top of each one.
Serve chilled and enjoy!
