Preheat your oven to 325°F (160°C). Line the bottom of a 9-inch springform pan with parchment paper or lightly grease it. In a medium bowl, combine graham cracker crumbs, sugar, melted butter, and salt until the mixture resembles wet sand. Press firmly into the bottom of the pan. Bake for 8-10 minutes until lightly golden. Set aside to cool.

Beat softened cream cheese with an electric mixer until smooth and creamy (2-3 minutes). Add sugar and vanilla extract, continuing to beat until fluffy. Add eggs one at a time, beating well after each. Mix in dulce de leche and flour until smooth. If using, incorporate sour cream for extra creaminess.

Pour the filling into the cooled crust. For a swirl pattern, warm extra dulce de leche for 10-15 seconds, drop spoonfuls on top, and use a toothpick to create a marbled effect.

Bake at 325°F for 1 hour 10 minutes until mostly set but slightly jiggly in center. Turn off oven and leave cheesecake inside for 1 hour to cool slowly (prevents cracking). Remove and cool completely at room temperature.

Cover with plastic wrap and refrigerate for at least 4-5 hours or overnight to set fully and develop flavors.

Remove from springform pan and place on a serving platter. Drizzle with extra dulce de leche and add whipped cream if desired. Slice with a clean, sharp knife between cuts.
