- STEP 1
Preheat the oven to 180C/350F/Gas 4.
- STEP 2
Grease and line a 20cm/8in tin.
- STEP 3
Place all of the cake ingredients, except the boiling water, into a large mixing bow and beat the mixture until smooth and well combined.
- STEP 4
Add the boiling water to the mixture, a little at a time, until smooth. (The cake mixture will now be very liquid.)
- STEP 5
Pour the liquid into the prepared tin and bake in the oven for 45 minutes, or until the top is firm to the touch and a skewer inserted into the centre of the cake comes out clean.
- STEP 6
Remove the cake from the oven and allow to cool completely, still in the tin, before turning out.
- STEP 7
Decorate as desired.
