Preheat the oven to 320°F (160°C). Grease and line an 8-inch springform pan with parchment paper.
Mix the biscuit crumbs with melted butter until the texture looks like wet sand.
Press the crumb mixture firmly into the base and up the sides of the pan.
Bake the crust for 8 to 10 minutes, then set aside.
Beat the cream cheese and sugar until smooth and creamy.
Add the sour cream, vanilla, and lemon zest. Mix until combined.
Add the flour and mix on low speed.
Add the eggs one at a time, mixing gently after each addition.
Pour the filling into the prepared crust and smooth the top.
Bake for 50 to 60 minutes, until the edges are set and the center has a slight wobble.
Turn off the oven, crack the door open, and let the cheesecake cool inside for 1 hour.
Cool completely, then refrigerate for at least 4 hours or overnight.
Decorate with berries and powdered sugar before serving.
