100g chocolate, 125g butter, 75g flour, 200g sugar. 2 medium eggs. The
one I did the other night had walnuts and almonds (a decent handful,
chopped and toasted) but I've done it with morello cherries instead
for more of a black forest gateau taste.
Make by melting butter (microwave is easiest) and mixing in the
chocolate - I use powdered chocolate so you'll probably want to chop
it first if you're using blocks of the stuff. When that's all melted
together resist any urge to drink it, and mix in the sugar, eggs and
flour. You could use power tools at this point but to be honest a fork
works just as well. Mix in whatever else you're adding (toast nuts
first in a dry frying pan or in the oven), pour the whole lot into a
buttered tray or cake tin and bake at 180c for about 20 minutes, or
until a skewer comes out clean (my oven is a psychopathic german thing
and may be faster than yours).
They need to cool down for a while before you can get them out of the
tin, and you can make your life a lot easier by lining the tin with
backing paper with a couple of tabs that come up out of the tin to
grab onto when removing it. I'm told they keep for a fair while in an
airtight container, but I've not been able to verify this in practice
as they have a tendency to, um, evaporate.
