Nutella Brownie Cheesecake

For the brownie layer:
Preheat oven to 180ºC (355ºF).

In a medium bowl, mix melted butter into Nutella until well incorporated. Add eggs and mix until smooth. Add brown sugar and mix until light and gooey.

In a separate bowl, whisk flour, cocoa powder and salt. Pour onto the wet ingredients and stir until incorporated.

Transfer mixture into a 9-inch springform pan sprayed with a little oil. Give it a little shake to make sure the mixture is evenly distributed. Place in oven to bake for 25 minutes.

For the cheesecake layer:
In a clean mixing bowl, beat cream cheese until light and fluffy. Fold in sugar, followed by sour cream. One at a time, crack eggs into the bowl and mix until light and fluffy. Finally, mix in Nutella until mixture is smooth.

Once brownie base has baked and had time to cool, wrap a 9-inch springform pan in two layers of foil and place a tray of water on the bottom shelf of the oven. Pour cheesecake mixture over the brownie base and jiggle around to evenly distribute. Place in the oven to bake for 1 hour. Turn heat off and let cool with door open for half an hour before placing in the fridge overnight.
