I didn't take a photo while I still had a chance - it disappered rapidly! - but this one sort of resembles... (Except this one's got an extra layer that mine hasn't got, and it's probably got 1 zillion more calories even than mine...)
By the way, with the number of chocolate cake images I've leafed through by googling, it would probably have saved a lot of time had I just baked and photographed it instead...
Procedure is very simple, you just mash it all together as you go:
150 g (3/4 cup or so...) ground almonds
3 eggs (without the shell...)
100 g (a little less than 1/2 cup) white sugar
1 teaspoon of baking soda (hey, I'm not going into 1/3 of a 1/16 of .. you check it out here... I'm no baker, there's a reason my kids were utterly flabbergasted!)
splash it all together until it's like a thick soup. Grease the cake tin (round, not too big..) on the bottom, but not the sides, it keeps the cake hanging on to be possibly half an inch thick at least..
30 minutes in the oven at about 180 (355? F). Leave to cool.
(Then people of course put all kinds of stuff on top of this, strawberries and cheesestuff and whatnot, but we've always had a bit of a sweet tooth, so here's what we do:)
100 g unmelted (I give up the conversions..) butter or margarine - to be mixed with -
100 g icing sugar (7/8 cup!) (apparently confectioner's sugar in American?). Mixmixetc.
Add 1 egg (without the ... yes! You remembered! Amazing...)
1 teaspoon coffee (some regular sort. Shaken, or even stirred.)
2 tablespoons (1/8 cup?) of cocoa powder. Or enough to make the stuff as brown as you wish. Not too brown...
2 tablespoons or more - vanilla sugar. More mixmixetc.
Put on cake when cake has cooled down. Sound the foodbell. Dig in. And kids? DO try this at home!
