Crimp a bunch of foil all around a 23-cm springform pan so no water can sneak inside. Butter up every part, including the sides. Then, kickstart your oven to 175°C.
02 -
In a big bowl, blend cookie crumbs and warm butter with your hands until they lump together. Smush this all over the base of your pan, running it partway up the edge.
03 -
Pop your crust into the oven, set a timer for 10 minutes. Let it cool down on a rack, then lower oven heat to 165°C.
04 -
Set a saucepan with just-simmering water, then rest a mixing bowl on top, but keep it out of the water. Drop in your chocolate and espresso powder. Stir every so often and let it melt fully. Leave the bowl on warm water for a bit.
05 -
Pitch all cream cheese into a food processor and run it until it’s totally creamy, should take 2 minutes. Stop and scrape the sides. Scoop in both sugars and cocoa powder, blend again. Drop eggs and yolks in, one at a time, giving each just a quick mix before tossing in the next.
06 -
While it’s running, stream in cream and vanilla, don’t stop for about 20 seconds. Mix just enough to pull it together.
07 -
Scrape in your melted chocolate from earlier and gently fold till you get a sticky, even blend.
08 -
Pour half that chocolate mix on your cooled crust. Scatter raspberries all around. Pour over the rest so they’re totally covered.
09 -
Drop your foil-lined pan into a roasting dish. Slide both into the oven, then add hot water until it’s up about 2.5 cm on the edge. Cook for around 70 minutes. When finished, the middle should shake a little but not look soggy.

Pull your cake from the water, open the foil so steam escapes, and run a thin blade around the edge to dodge cracks. Let the whole thing chill out in its pan till it’s no longer warm.
11 -
Move your cooled cake right into the fridge. Let it hang out there at least 6 hours before freeing it or slicing up.
12 -
Toss chocolate bits in a heatproof bowl. Gently warm up your cream until it’s almost bubbling, pour it over the chocolate. Wait a minute, then whisk until silky. Add butter and stir till smooth. Let that mixture sit on the counter until it thickens a little.
13 -
Work ganache over the top of your cake with a spatula. Let it sit out about an hour so it sets nicely.
14 -
Grab a thin, sharp knife and slice, wiping it off every time for neat pieces. Finish each one with some chocolate sauce, raspberries, and if you want, a little sprinkle of cocoa. Store any extras covered in your fridge for up to 5 days.
