Method

  1. Heat oven to 180C/fan 160C/gas 4. Butter and line the base of a 18 x 28cm cake tin or tray. Put the butter and sugar into a bowl; beat together with electric hand beaters until light and fluffy. add the eggs a little at a time, beating well between each addition.

  2. Sieve the flour, cocoa and bicarbonate of soda into the bowl, then tip in any bran left in the sieve. Pour in the natural yogurt. Stir everything to a smooth mixture and spoon into the prepared tin. Bake for 20-25 mins until just firm and shrinking away from the sides of the tin. Cool in the tin for 5 mins, then turn onto a wire rack to cool completely.

  3. For the icing, sieve the icing sugar and cocoa into a bowl, then pour in the butter and 2 tbsp just-boiled water. Stir together to a smooth, spreadable consistency. if it’s too stiff, very carefully add a little more boiling water, drop by drop.

  4. Spread the icing over the top of the cake, using a palette knife dipped in hot water. Will keep in an airtight container for up to 1 week.

  5. Melt the chocolates in three different bowls in the microwave on High for 1 min or over a pan of simmering water. Spoon the melted chocolates into three plastic disposable piping bags. Snip the ends off and pipe 12 simple shapes on top of the cake. Leave to set. Just before serving, cut the cake into 12 squares and push in the candles.

I made this cake for mother's day and everybody enjoyed delicious! But I confess I had some doubts: the coverage needed much more water than the recipe demanded, the coverage was difficult to extend and much thicker than it seemed in the picture. Also did not find self raising wholemeal flour and had to use self raising white flour. Can you tell me how much I would have to use of baking powder in wholemeal flour? Oh, very well and resulted in a square 20x20cm.

The easiest cake Ive made so far. Instead of piping on shapes, I just grated a few blocks of milk and white chocolate across the top of the cake, went down a treat :)

I make lots of different cakes and decided to try this one for a joint birthday for my husband and a friend.Made a ganache instead of icing as suggested by someone in comments and it was lovely but the cake itself was awful.Tasted like a "diet" cake.Had to apologise for it tasting so yuk even though it looked lovely.Gave most of it to my chickens.

I made this for my husband's birthday and it was lovely. I used two 9 inch round tins as I haven't got a square one. I could only find drinking chocolate in the cupboard so I grated some extra chocolate in to the mixture and also used self raising flour rather than wholemeal flour. I made the topping and used some of it to sandwich the two cakes together. My little boy and I then finished it off with grated chocolate and sprinkles. It looked great and tasted delicious. Everyone commented on how light and moist it was. Will definitely make it again.

A bit sharp for my liking, but it did age well.

Made this cake yesterday for my sons birthday. Bought everything except piping bags, but was good enough with icing pens and sprinkles.
