Lemon Layer Cake

Heat the oven to 180C for a fan oven.

Grease and line 3 tins. Then grate the rind of a lemon and then juice the lemon.

Sift the flour and baking powder into a bowl. Stir in the margarine and sugar. Break the eggs into a cup and beat them in too.

Stir in the lemon juice and rind. Split the mixture between the tins and bake for 20 minutes. Turn the cakes out onto a wire rack. Leave to cool.

For the filling, break the eggs into a heatproof bowl and beat them. Add the sugar, lemon rind and the juice of a lemon.

Cut the butter into chunks and add them. Put 5cm water into a pan. Heat until it bubbles. Put the bowl into the pan.

Stir the mixture as it thickens. After 20 minutes, the mixture should coat the back of a spoon. (If not carry on heating) Take the pan off the heat.

Spread a cake with half of the filling. Put another cake on top. Spread the rest of the filling over that cake. Put the final cake on top. Don't worry if some filling oozes out.

Grate the rind of a lemon. Use a zester if you have one. For the icing, squeeze the juice from half of the lemon. Sift the icing sugar into a bowl.

Stir the lemon juice into the icing until it is smooth. Spread the icing over the cake. Sprinkle the rind on top of the cake and enjoy :)
