MARS BAR CAKE
For the Shortbread
150g/5oz butter
100g/4oz caster sugar
275g/10oz plain flour
For the Caramel
100g/4oz butter
100g/4oz caster sugar
2 x 15ml spoons (tablespoons) golden syrup
1 large can condensed milk
Topping
2 large bars chocolate, (I use 1 x milk and 1 x plain.)
1 x 30 x 22cm (12? x 9?) Swiss roll tin, greased.
Method - Shortbread
Cream the butter and sugar together in a mixing bowl. Work in the flour until the mixture looks like fine breadcrumbs. Press the mixture into the greased Swiss roll tin. (tip ? use the back of a metal spoon to press it down, and make sure that it is pressed down as firmly as you can get it.) Bake at 180C/350F for 15 ? 20 min, until the base is golden brown. Remove from the oven and allow to cool until COLD.
Method ? Caramel
Put all the caramel ingredients into a saucepan and heat GENTLY until the sugar has dissolved. DO NOT STOP STIRRING as the bottom will burn. Increase the heat gradually until it boils, and boil the mixture for 5 minutes. DO NOT STOP STIRRING. If you see little brown bits in the caramel it is too hot too soon, so adjust the heat accordingly. (tip ? use a wooden spoon, and if you rush this bit you will burn the caramel. Little brown bits are ok, but bigger brown or black bits are burnt and taste horrible. Take your time) Remove from the heat and allow to cool for about 1 minute. Pour the caramel onto the cold shortbread base, making sure it is spread all over. IMPORTANT - allow to cool until cold and set.
Melt the chocolate either in a bowl over a pan of hot water or in the microwave. When set, the cocolate can crack so I add about 1/4 teaspoon of vegetable oil to the chocolate while it is melting, it makes the set chocolate easier to cut without breaking.
Spread this over the set caramel and shortbread. Allow to cool until the chocolate is set, then cut into portions and enjoy!
The trick to this recipe is to make sure that you take your time with the caramel and that you let each layer get cold, not just cooler, before adding the next layer.
And the great thing about it is that it takes a long time to let everything cool in between, so if you start at about 7pm you can keep yourself occupied until at least 11pm.
