Chocolate Birthday Cake!

It was lovely Chris' birthday last weekend, so I made him the most chocolaty of chocolate cakes. I don't actually like icing so this cake is perfect, as the topping is basically just melted chocolate. As far as I'm concerned it's the best chocolate cake recipe EVER! I'm not sure where it was originally printed, but it's a hand me down from my madre. Anyway, I command you to make this cake:

For the cake:

165g self-raising flour

165g caster sugar

165g soft margarine

3 large eggs, beaten

1.5 level tsp baking powder

1.5 tbsp milk

2 rounded tbsp of cocoa powder

1. Butter the cake tins and line the bottom with baking parchment. Put the oven on to preheat to 170 degrees
2. In a large bowl blend all the ingredients with a hand mixer until smooth, but do not over mix
3. Divide into the prepared sandwich tins and bake for 25-30 min until a knife comes out from the middle clean

For the topping:

One small tin carnation evaporated milk

115g light muscovado sugar

115g chocolate broken into pieces

55g soft butter

Few drops vanilla essence

1. Combine the sugar and evaporated milk in a small heavy based pan and heat gently until the sugar has dissolved, stirring often
2. When dissolved bring to the boil and then turn down and simmer for 5 minutes without stirring
3. Take off the heat and add the remaining ingredients. Stir briskly until it all becomes smooth and glossy
4. Leave to cool (but not chill) before spreading on the cakes
