Ingredients:

For the sponge:

50g cocoa powder

Six tablespoons of boiling water

100g baking spread

275g caster sugar

Three large eggs

125ml milk

175g self-raising flour

One teaspoon of baking powder

For the icing:

Three to four tablespoons of warmed apricot jam

100ml double cream

200g milk chocolate, chopped

For the decoration:

Chopped sweets, optional

White chocolate, optional

Marshmallows, optional

Method:

Preheat the oven to 180C or 160C Fan and grease a 30x23cm traybake tin with butter and then line it with baking parchment.

Put the cocoa in a bowl and add the boiling water, mixing until smooth. Add the baking spread or butter and beat into the cocoa until smooth, then add the remaining cake ingredients.

Mix until combined before pouring it into the tin and bake for around half an hour, until it shrinks away from the sides.

Leave to cool in the tin for 10 minutes and then turn it out and peel off the parchment. Use a pastry brush to brush the top of the cake with apricot jam and then leave to cool.

For the icing, warm the cream in a small pan and then add the milk chocolate until completely melted and smooth.

Leave to cool a little and then pour the icing over the cake, spreading it out with a palette knife.

If making the feather decoration, melt 100g of white chocolate and then place it in a piping bag or sandwich bag, snipping the end off.

Pipe lines down the cake about 1cm apart and then, using a cocktail stick, drag through the white chocolate in opposite directions.
