This New York-style Chocolate Ganache Cheesecake consists of cream cheese, sour cream, eggs, nutmeg, vanilla extra, and cornstarch on a vanilla wafers crust with a sour cream and powdered sugar topping with rum chocolate ganache and fresh raspberries.
Heavily coat a springform cheesecake pan with butter. Set aside.I am a purist when it comes to cheesecake. I do not recommend spraying it with olive oil or attempting a cheesecake in anything other than a cheesecake pan! It will not have the same flavor and it will not come cleanly out of any other type of pan.
Add vanilla wafers to food processor and process for 1-2 minutes, or until the wafers turn into fine crumbs.You want 1 1/2 cups of vanilla wafer crumbs, so you'll need to add about twice as much whole vanilla wafers to reach this amount. I find it easier to just weigh out 200 grams, which is the equivalent of 1 ½ cups. It's also okay if it's slightly more or slightly less. This isn't the kind of cake where 205 grams is going to matter.
Add butter and sugar to vanilla wafer crumbs and process for 2 minutes, or until the mixture is fully incorporated and begins to form a ball.
Add wafer mixture to the springform pan and firmly pack down.
Bake for 10 minutes.
Remove from oven and set aside.
Filling
Turn the oven up to 425 degrees Fahrenheit. Place a large baking dish on the bottom rack of the oven and fill with water.DO NOT SKIP THIS STEP. An essential part of making cheesecake is creating steam in the oven.
Add cream cheese, sour cream, and sugar to a food processor. Process for 2-3 minutes, or until smooth.
Add eggs gradually, along with nutmeg, vanilla extract, and cornstarch. It’s best to add 1 egg at a time and process until barely incorporated, about 10-15 seconds per egg.DO NOT OVERBEAT. I repeat, DO NOT OVERBEAT! There is nothing that will ruin the texture of a cheesecake faster than overbeating the eggs.
Pour filling on top of the crust. Let sit for a couple minutes and tap or shake lightly.This will let the air bubbles rise to the surface and will prevent the bubbles from causing brown spots or cracks in the cheesecake. DO NOT SKIP THIS STEP!
Bake for 45 minutes. The cheesecake should be very lightly browned on top.
Check after 30 minutes and turn down the heat if browning too quickly.
Turn off the oven and place a wooden spoon the door to prop it open. Let sit for 1-2 hours, or until cool. This will allow the cheesecake to set without removing it from the oven.I cannot stress this enough: DO NOT TOUCH IT! DO NOT REMOVE FROM THE OVEN! DO NOT REMOVE FROM THE PAN! AND DO NOT CUT!
After the cheesecake is cool, put in the refrigerator and let sit for at least 12 hours. It’s best to bake in the evening and let it set overnight. It will not turn out if you try to cut into it too early.
Topping
Mix sour cream and powdered sugar together.
Spread evenly across the top of the cheesecake.It doesn't have to be pretty, we're going to cover it up! Although you could stop at this point, if you don't want to make ganache. I've made plenty of cheesecakes that are just topped with
Chocolate Ganache
Dice, chop, shred, or otherwise make your chocolate smaller. Add to a large heat-safe bowl.
Heat heavy whipping cream until warm, but not boiling.I did this on the stove and stirred constantly until heated. You can likely do this in a microwave. Just make sure that it doesn't boil, foam, or curdle.
Immediately pour cream over chocolate, whisking constantly.
Add in rum and continue to mix for about 2 minutes. The ganache should be smooth, shiny, and the texture of hot fudge.
Let cool at room temperature until it reaches the consistency that you need it for and spread over the cheesecake.
Arrange raspberries on top.
Refrigerate and serve within 24 hours.
Tips, Tricks, & Notes
Cheesecake will keep for 2-3 days in an airtight container in the refrigerator. It will technically keep for longer and is still fine to eat. However, after a couple days in the refrigerator the butter will begin to separate, so I advice eating it sooner rather than later!
