In a medium bowl with an electric mixer, beat together the cream cheese and sweetened condensed milk until combined.
Add the egg and beat until combined.
Add the lemon juice and vanilla and beat until just combined.
Tap the bowl on the counter several times to release any air bubbles created while mixing.
Arrange the raspberries on top of your cooled pie crust, breaking up any chunks.
Pour the cheesecake mixture over the raspberries. Some will float to the top just make sure they aren't peaking out of the mixture.
Bake for 28-32 minutes until set.
Cool completely.
