Chocolate cheesecake

Preheat your oven to 160°C (325°F).
Grease a 9-inch (23cm) springform cake tin and line the bottom with parchment paper.
Crush the chocolate digestive biscuits into fine crumbs using a food processor or a zip-top bag and a rolling pin.
Mix the melted butter with the biscuit crumbs until the mixture resembles wet sand.
Press the biscuit mixture into the bottom of the prepared tin to form an even crust.
Bake the crust for about 10 minutes, then remove it from the oven and let it cool while you prepare the filling.

In a large mixing bowl, beat the cream cheese until smooth and creamy.
Gradually add the granulated sugar and continue to beat until well combined.
Add the melted and cooled dark chocolate to the cream cheese mixture, and mix until fully incorporated.
In a separate bowl, whisk the heavy cream until it forms stiff peaks.
Gently fold the whipped cream into the chocolate cream cheese mixture.
Add the eggs, one at a time, mixing well after each addition.
Stir in the vanilla extract.
Pour the cheesecake filling over the prepared crust and smooth the top.

Place the cheesecake in the preheated oven and bake for about 45 minutes or until the edges are set, and the center is slightly jiggly.
Turn off the oven, crack the oven door slightly, and let the cheesecake cool in the oven for about an hour.
Remove the cheesecake from the oven and refrigerate it for at least 4 hours or overnight to allow it to set.

Chop the dark chocolate finely and place it in a heatproof bowl.
In a small saucepan, heat the heavy cream until it begins to simmer.
Pour the hot cream over the chopped chocolate and let it sit for a minute.
Stir the mixture until the chocolate is completely melted and the ganache is smooth.
Let the ganache cool for a few minutes, then pour it over the chilled cheesecake.
Spread the ganache evenly over the top of the cheesecake.

Refrigerate the cheesecake for another hour or until the ganache sets.
Remove the cheesecake from the tin, slice, and serve. Enjoy your delicious chocolate cheesecake!
Note: You can also garnish the cheesecake with chocolate shavings or fresh berries if desired.
