In a stand mixer, beat the cream cheese and sour cream until smooth.
Add the vanilla and mix until it’s incorporated into the cream cheese mixture.
With the mixer on low add the powdered sugar in small batches and continue to mix until combined.
Taste the mixture and increase the powered sugar to desired sweetness if serving plain. (This cheesecake is intended to have fresh fruit on top. It’s not as sweet as a cheesecake you would eat plain.)
In a small bowl, whisk the heavy cream until stiff peaks form.
Fold the whipped cream into the cheesecake mixture.
Pour the mixture into the graham cracker crust. Use an offset spatula to smooth the top into an even layer. Cover with plastic wrap and chill for 2 hours or up to overnight.
Remove the cheesecake from the springform pan to a cake plate or platter.
Thinly slice the strawberries and place on top of the cake for garnish.
Serve.
