Creating these delightful bites involves a few simple steps:

1. Preheat your oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners.
2. In a bowl, mix the crushed chocolate wafer cookies with melted butter until the mixture resembles wet sand.
3. Press the mixture into the bottom of each muffin cup, creating an even layer for the crust.
4. Bake the crusts for 5 minutes and let them cool while you prepare the filling.
5. In a large bowl, beat the cream cheese until smooth. Add sugar and cocoa powder, mixing until well combined.
6. Add in the eggs, one at a time, followed by the vanilla extract. Mix until the batter is smooth and creamy.
7. Pour the cheesecake batter evenly over each crust.
8. Bake for 18-20 minutes or until the centers are set. Let them cool completely.
9. In a small saucepan, heat the heavy cream over medium heat until it begins to simmer. Pour over the chopped dark chocolate and let it sit for a minute before stirring until smooth.
10. Top each cooled cheesecake bite with the melted chocolate ganache.
11. Chill the bites in the refrigerator for at least 2 hours before serving.
