1. Preheat oven to 325 degrees. Spray the sides of a 9-inch springform pan with nonstick baking spray and line the sides of the pan with strips of parchment paper. You can also opt for a nonstick baking spray with flour and forget the strips of parchment paper.
2. Add the cookies in a food processor. Pulse until all of the cookies are just crumbs. Remove any large pieces of cookie.
3. Add in the butter and pulse until the cookie crumbs resemble wet sand.
4. Press the cookies into the bottom of the 9-inch springform pan.
5. Place in the fridge or freezer while preparing the cheesecake filling.

Cheesecake

1. Add the cream cheese to a mixing bowl. Beat on medium with a hand mixer until the cream cheese is smooth. Scrape down the sides and bottom of the bowl.
2. Add the sugar and beat until incorporated.
3. Add the eggs one at a time. Beat each egg in before adding the next. Scrape down the sides and bottom of the bowl.
4. Add the sour cream, raspberry puree, and vanilla extract. Beat on medium until it's just incorporated. Scrape the sides and stir in any remaining sour cream or raspberry puree.
5. Pour half of the batter into a separate bowl. Try to keep it as even as possible. I used a scale, but a measuring cup would work as well.
6. Add the raspberry extract and food coloring, if you're using it, to one of the bowls of cheesecake batter. I left the food color out. Stir until everything is combined.
7. Melt the chocolate chips in a medium microwave-safe bowl by microwaving in 30-second increments and stirring after each increment. Repeat until the chocolate chips are completely melted.
8. Add 1/2 of a cup of batter from the second bowl into the bowl with the melted chocolate. Immediately start stirring in the batter into the chocolate to avoid the chocolate seizing up or cooling down too much.
9. Once the batter is incorporated, add the cocoa powder to the chocolate mixture. Stir until it's completely incorporated.
10. Now pour the chocolate mixture into the second bowl of cheesecake batter. Stir to combine.
11. Add the chocolate cheesecake batter to the springform pan first. Spread it out evenly.
12. Slowly pour the raspberry cheesecake batter on top to avoid it plopping into the pan and disturbing the chocolate layer. Spread it out so it covers all of the chocolate batter. You can also spoon the raspberry batter on top instead.
13. Wrap the springform pan with heavy duty tin foil. I like to do two layers of tin foil to keep the water out of the cheesecake. Place the cheesecake into a slightly bigger pan and fill with an inch to two inches of hot water.
14. Place in the oven and bake for 1 hour 20 minutes - 1 hour 30 minutes until done. To make sure the cheesecake is done, give it a wiggle. If it slightly jiggles in JUST the middle like jello, then it's done. If it jiggles on the edges, it needs to bake longer. Turn off the heat and crack the oven door slightly. Let it cool in the oven.

Ganache

1. Once the cheesecake has cooled to room temperature, begin making the ganache.
2. Add the chocolate chips and heavy cream into a microwave-safe bowl. Microwave in 30-second increments and stir after each increment. Repeat until the ganache looks like a smooth chocolate syrup.
3. Pour the ganache on top of the room temperature cheesecake. Place in the fridge until the ganache begins to thicken up. It will take 1 - 2 hours.
4. Add the fresh raspberries on top of the ganache and place back into the fridge overnight or at least 6 hours for the cheesecake to firm up.
