Cocoa cheesecake with marshmallows

Ingredients:

Cake

• 90g unsalted butter, melted, plus extra for greasing the pan
• 9 graham crackers (about 1 pack)
• 1/4 cup hot chocolate or cocoa mix
• A pinch of fine salt
• Special equipment: springform pan with a diameter of 22 cm.

Filling

• 4 packages of cream cheese, 220 g each, at room temperature
• 1 cup of sugar
• 2/3 cup hot chocolate or cocoa mix
• 1 cup sour cream
• 6 large eggs, room temperature
• 1 tbsp vanilla extract
• 10 marshmallows

Preparation:

1. Position a rack in the center of the oven and preheat the oven to 160°C.
2. Cake:
   
   Grind the graham crackers in a food processor until fine crumbs form. Add the butter, hot chocolate mix, and salt and pulse until the mixture comes together and holds its shape when pressed.
3. Pour the mixture into the prepared pan and press it into the bottom to form an even layer. Bake until the crust is set, about 10 minutes. Let cool completely. Place the pan with the crust on a large piece of foil and wrap the outside of the pan with foil to prevent water from seeping in during baking.
4. Filling:
   
   Wipe out the bowl of a food processor. Beat the cream cheese, sugar, hot chocolate mix, and sour cream until smooth and lump-free, scraping down the sides of the bowl several times. Add the eggs and vanilla extract and beat until smooth.
5. Spread the filling on the crust and place the pan in a roasting pan. Fill the roasting pan with enough hot water to reach halfway up the foil-lined pan.
6. Bake the cheesecake until the edges are set but the center jiggles slightly when you shake the pan (the cheesecake should ripple), 1 hour 10 minutes to 1 hour 20 minutes.
7. Turn off the oven and crack the door for a few seconds to release some of the heat. Close the door and let the cheesecake sit in the oven until completely set, about 1 hour.
8. Transfer the cheesecake pan to a wire rack. Run a knife around the edge and let the cheesecake cool to room temperature. Wrap and refrigerate overnight or for up to 2 days..
9. Before serving, cut the marshmallows diagonally and arrange them, cut side down, in a neat line around the edge of the cheesecake.
