This German Black Forest Cheesecake is a chocoholic's dream. Creamy, indulgent chocolate cheesecake on a chocolate Graham cracker crust, and topped with Kirsch marinated sweet cherries and a homemade cherry infused whip cream.
Soak the cherries in the kirschwater for at least 4 hours or overnight. For less alcohol flavor only soak half of the cherries and reserve the remaining cherries.
Make the Crust
Finely chop the crackers in a food processor. Add the melted butter and sugar and pulse to combine.
Form the crust into a greased 9 inch springform pan and refrigerate until needed.
Make the Filling
Add the sugar, softened cream cheese, and quark to the bowl of a stand mixer. Mix the cream and sugar together until it is smooth. Scape the sides of the bowl then add the cocoa powder and mix to combine.
Add the eggs one at a time, mixing and scaping between each addition.
Melt the chocolate using a double broiler on in a metal pan over a pot of simmering water.
Add the melted chocolate to the bowl with the cream cheese mixture along with the chopped cherries and 1 teaspoon of vanilla.
Pour over the graham cracker crust and smooth and even our the top.
Bake the Cheesecake
Bake at 350 degrees for 1 hour rotating half way through. The cake is done when the center barely jiggles and the top no longer appears wet.
Refrigerate, uncovered overnight.
Make the Whipped Topping
Add the heavy cream, powdered sugar, cherry juice, and vanilla to a bowl and beat until stiff peaks are formed.
If using an iSi Whip add all the the chilled ingredients and use one charge for the iSi Whip. Shake 5-8 times or until it reaches the desired consistency.
Make the Cherry Topping
Remove the cherries from the fridge and pour over a strainer. Reserve the cherry juice and set aside.
Stir the sugar in with the cherries then add to a sauce pan. Heat over medium heat, stirring occasionally.
In a separate bowl add the cornstarch in with ¼ cup of the reserved cherry juice and stir until smooth.
After about 5 minutes the cherry mixture should reach a boil. At this point stir in the cherry juice-cornstarch mixture and stir until the syrup has thickened, about a minute. Remove the pan from the heat and stir in 1 teaspoon of lemon juice. Chill the mixture in the refrigerator until ready to use.
Assemble the German Black Forest Cheesecake
