Method
 

  1. Step 1: Prepare the Cake Base
    1. Preheat your oven to 175°C (350°F). Get an 8-inch springform pan ready by lining the bottom with parchment paper and giving the sides a good grease. 2. In a mixing bowl, cream together softened butter and sugar. Beat it for about 4 minutes until light and fluffy. 3. Add in the sour cream, milk, and vanilla, mixing them in well. Then, beat in the single large egg until perfectly combined. 4. Gently fold in your flour and baking powder. Do not overmix. 5. Pour batter into prepared pan and bake for about 25 minutes, or until a toothpick comes out clean. 6. Once baked, let it cool completely in the pan.
  2. Step 2: Create the Cheesecake Layer
    1. Reduce oven temperature down to 150°C (300°F). 2. In a large bowl, using a low speed on your mixer, beat softened cream cheese, sugar, flour, salt, and vanilla until smooth. Scrape down the sides often. 3. Add the sour cream and heavy cream, mixing again on low speed just until fully incorporated. 4. Add the eggs, one at a time. Mix just until the yolk disappears after each addition. Do not overmix. 5. Pour cheesecake batter over your cooled cake layer in the springform pan. 6. Place springform pan inside a larger roasting pan. Carefully pour hot water into the larger pan, making sure it comes about halfway up the sides of the cheesecake pan. 7. Gently slide this whole setup into your preheated oven. Bake for approximately 90 minutes. The center should look almost set, maybe a little jiggly still, but the edges should be firm. 8. Once baked, turn off the oven but leave the cheesecake inside with the door slightly ajar for about 10 minutes. 9. Carefully remove the cheesecake from the water bath. Use a small knife to gently run it around the edge of the pan. 10. Let cool at room temperature for 1-2 hours before refrigerating it, preferably overnight, to set up properly.
  3. Step 3: Make the Boston Cream Filling
    1. In a medium saucepan (off the heat), whisk together egg yolks, sugar, and cornstarch until a smooth paste. 2. Gradually whisk in the whole milk until all incorporated and smooth. 3. Place saucepan over medium heat and stir constantly until mixture comes to a boil. Once boiling, continue to cook and stir vigorously for another 2-3 minutes until thick. 4. Strain the hot filling through a fine-mesh sieve into a clean bowl. 5. Stir in the butter and vanilla until completely melted and combined. 6. Cover the surface of the filling directly with plastic wrap. Chill until cold.
  4. Step 4: Prepare the Chocolate Ganache
    1. Put chocolate chips or chopped chocolate into a heatproof bowl. 2. Heat heavy cream in a small saucepan or microwave until just simmering. 3. Pour hot cream right over the chocolate. Let it sit for 2-3 minutes. 4. Starting from the center, gently stir the mixture until completely smooth, glossy, and luscious. 5. Let the ganache cool slightly to thicken up but still be pourable.
  5. Step 5: Assemble the Cheesecake
    1. Take your well-chilled cheesecake out of the refrigerator. 2. Spread the equally well-chilled Boston cream filling evenly over the top of the cheesecake layer. 3. Pop it back into the refrigerator for about 10 minutes. 4. Pour the slightly cooled ganache over the top. You can carefully spread it or tilt the pan slightly. 5. Return the finished masterpiece to the refrigerator for at least another 2 hours to let the ganache set up completely. Then, slice and enjoy.

Notes

Tips for Success: Use room temperature ingredients for the cheesecake and sour cream for smooth mixing. Avoid overmixing ingredients, especially the cheesecake eggs, to prevent cracks. Do not skip the water bath for baking the cheesecake, it helps prevent cracks. Allow plenty of time for cooling slowly and chilling thoroughly in the refrigerator. Cover pastry cream directly with plastic wrap to prevent a skin from forming. You can make the cake base, pastry cream, and ganache ahead of time.
Storage: Store assembled cheesecake in the refrigerator, covered loosely or in an airtight container, for 3-4 days. If freezing, freeze the baked cheesecake layer before adding filling and ganache; thaw overnight in the refrigerator before assembling.
Substitutions & Additions: Try a chocolate cake base by swapping flour for cocoa powder. Use dark or milk chocolate for the ganache. Garnish with fresh berries. Add a touch of almond extract to the cake or pastry cream.
