Preheat oven to 160°Celsius.
Crush the Oreo cookies into crumbs by processing them in a food processor or by putting them in a zip lock bag and pressing them with a rolling pin. Place the crumbs in a bowl, add the melted butter and mix.
Transfer the crust mix into a parchment paper-lined 7 inches round springform pan and press it down evenly and firmly. Set aside.
In a separate bowl, beat cream cheese until smooth for 30 seconds.
Scrape the sides of the bowl, add the sugar, flour, and salt. Beat again for 20 seconds.
Add in both the eggs and vanilla extract. Beat for about 10 seconds until the eggs are well combined. Scrape the bowl and continue beating for another 10 seconds until the batter is all smooth and creamy. Do not overbeat to avoid the batter from incorporating too much air.
Fold in the sour cream until it is well incorporated into the batter, followed by the strawberry filling.
Pour the batter into the prepared crust and bake in a water bath for 55 minutes at 160 °Celsius. When done, the sides should be firm and the center of the cake still wobbly. Turn the oven off and leave the cake in the oven for another 10 minutes.
Remove from oven and let the cake cool for another 20 minutes before loosening the cake tin and removing the cake out.
Let the cake rest in the refrigerator for at least 4 hours or overnight before serving.
Garnish the cake with a layer of fresh whipped cream and strawberry halves.
Keep leftovers refrigerated.
