Preheat oven to 325 degrees. Spray the sides of the 9.5-inch springform pan with nonstick baking spray. Wrap the sides of the pan with a strip of parchment paper.
In a mixing bowl, add in the chocolate crumbs, sugar, and melted butter. Stir to combine.
Firmly press the crumbs evenly into the bottom and up the sides of the prepared pan.
Place in the oven and let bake for 15 minutes. Remove from the oven and let cool while you work on the cheesecake filling.
Cheesecake
In a mixing bowl, add in the cream cheese. Beat with a hand mixer on medium until smooth. Scrape the sides and bottom of the bowl.
Add in the sugar and flour. Beat until incorporated.
Add in the vanilla extract and then the eggs one at a time. Beat in each egg completely before adding the next. Scrape down the bowl after incorporating each egg.
Add in the cherry juice and sour cream. Mix until incorporated.
Stir in the chopped cherries and chocolate.
Just before adding the cheesecake mixture, wrap the outside of the springform pan with 2 layers of heavy-duty tin foil.
Pour the cheesecake filling into the crust.
Place the springform pan in a slightly larger baking pan. Fill the outer pan with 1 inch of water. This will keep the cheesecake from cracking.
Place in the oven at 325 degrees and let bake for 1 hour and 30 minutes or until done. To make sure the cheesecake is done, gently give it a wiggle. If it slightly jiggles in JUST the middle like jello, then it's done. If it jiggles all over, it needs to bake longer. Turn off the heat and crack the oven door slightly. Let it cool in the oven for 1 to 2 hours until it reaches room temperature and then place in the fridge to chill overnight.
Ganache
In a microwave-safe bowl, add in the chocolate chips and heavy cream. Microwave for 30 seconds and stir. Repeat microwaving for 30 seconds and stirring until the ganache comes together. It will look like a chocolate syrup.
Pour the ganache in the center of the chilled cheesecake and spread out with a knife.
Add the stemmed cherries on the edges of the cheesecake.
