Step 1: Prepare the Brownie Base

1. Preheat oven to 325°F (160°C). Grease and line the bottom of a 9-inch springform pan.

2. In a mixing bowl, combine melted butter, sugars, eggs, and vanilla. Whisk until smooth.

3. Stir in cocoa powder, flour, and salt until just combined.

4. Fold in chocolate chips (if using).

5. Spread brownie batter evenly into the pan. Bake for 18–20 minutes—just until set (it will bake more with the cheesecake).

6. Remove from oven and let cool slightly while preparing cheesecake layer.

Step 2: Make the Cheesecake Filling

1. In a large bowl, beat cream cheese until completely smooth.

2. Add sugar, sour cream or cream, and vanilla. Mix well.

3. Beat in eggs, one at a time, on low speed to avoid incorporating too much air.

4. Scrape sides and bottom of bowl to ensure smoothness.

---

Step 3: Assemble and Bake

1. Pour cheesecake batter over the slightly cooled brownie base.

2. Smooth the top with a spatula.

3. Wrap the springform pan in foil and place in a water bath (a roasting pan with 1 inch of hot water).

4. Bake at 325°F for 50–60 minutes, until the edges are set and center slightly jiggles.

5. Turn off oven, crack the door, and cool cheesecake inside for 1 hour.

6. Remove and refrigerate at least 6 hours or overnight.

---

Step 4: Optional Ganache Topping

1. Heat cream in a saucepan until just steaming.

2. Pour over chopped chocolate and let sit 2 minutes.

3. Stir until smooth and glossy.

4. Pour over chilled cheesecake and spread gently.

5. Let set before decorating with whipped cream, sprinkles, or candles.
