1/2 cup light muscovado sugar or light brown sugar
8 ounces best-quality bittersweet chocolate
3/4 cup black coffee and 3/4 cup water*
2 eggs, beaten slightly
8 ounces raspberries plus more, for serving
Confectioners' sugar, for dusting
* or instant coffee made with 2 teaspoons instant coffee and 1 1/2 cups boiling water
Heat oven to 350 degrees F.
Butter an 8-inch springform pan and line the base with baking parchment. Sift
the flour, baking powder, salt, and cocoa powder together in a bowl and set aside.
Put the butter, framboise, sugars, chocolate and coffee with water in a heavy-bottomed
saucepan and stir over low heat until everything melts and is thickly, glossily
Stir this mixture into the sifted flour and cocoa. Beat well until all is smooth
and glossy again, then beat in the eggs. This will be runny - don't panic, and
don't add more flour; the chocolate itself sets as it cooks and then cools.
Pour into the prepared pan until you have covered the base with about an inch
of the mixture, and then cover with raspberries and pour the rest of the mixture
on top. You may have to push some of the raspberries back under the cake batter
by hand. Bake 45 to 50 minutes, until the top is firm and probably slightly cracked;
don't try to test by poking in a skewer as you don't want it to come out
clean; the grunge is what the cake is about. When it's ready, take the cake
out of the oven and put on a rack. Leave in the pan for 15 minutes and then turn
When you're just about to eat, dust the cake with the confectioners'
sugar tapped through a strainer.
Serve with the additional berries, piled in a bowl.
