Line just the bottom of a springform pan (23 cm) with parchment, grease the sides, and set your oven to heat up to 175°C.
02 -
Add your brownie mix, the oil, the water, and both eggs to a bowl. Stir until it looks and feels glossy and there aren’t dry spots.
03 -
Spoon the brownie mix into your lined pan. Pop it in the oven for about 15 minutes till it’s just set on top.
04 -
Soften the cream cheese and beat until totally smooth. Keep adding the sugar and flour while you mix until it’s lump-free.
05 -
Now pour in your vanilla and sour cream, mixing it well. Stir in the egg with your hand, going slow so you don’t whip in too much air.
06 -
Once the brownie’s done, pour the cheesecake batter right on top while it’s still a bit warm. Smooth it out evenly.
07 -
Drop oven temp to 160°C. Bake for 45 minutes. You want the middle to jiggle just a little.
08 -
Turn the oven off and leave the cheesecake inside for 20 minutes—door shut. After that, crack the door and let it chill another 30 minutes inside.
09 -
Take out the cheesecake, set it on the counter to cool a bit, then stick it in the fridge for 2–3 hours till it's cold and set.

Using a mixer, beat heavy cream and icing sugar together until stiff peaks form. This just means it holds its shape when you lift the beaters.

Dollop whipped cream over your cold cheesecake. Drizzle with fudge or chocolate and toss on berries or chocolate curls if you like. Now slice it up and enjoy.
