Lemon custard filled cake with meringue topping

So last night it was my husband's turn to cook, so we had pizza from Toni's. I decided I wanted to use my time to make this really delicious cake - I have been wanting to make this cake forever! It seems to be flop proof.....it looks like a really long list of ingredients but this cake is very easy to make. Here is the recipe for my cake take on a lemon meringue pie:

Base:

• 125g butter
• 80ml castor sugar
• 4 extra large egg yolks
• 250ml cake flour
• 10ml baking powder
• 2ml salt
• 125ml milk

Meringue

• 4 extra large egg whites
• 1ml cream of tartar
• 200ml castor sugar

Custard

• 350ml milk
• 45ml sugar
• 45ml custard powder
• fine zest of a lemon
• juice of half a lemon
• 125ml fresh cream, whipped (optional)

Method:

• For the cake base, cream butter and sugar together, then add egg yolks one at a time and beat until light and fluffy. Sift flour, baking powder and salt together and add alternately with the milk to the butter, sugar and egg mixture. Divide the cake batter between 2 greased 23cm loose-bottomed cake pans.
• For the meringue, beat the egg whites until foamy then add cream of tartar and carry on beating. Gradually beat in the sugar until soft peaks form. Spread the meringue over the uncooked cake batter.
• Bake in a preheated oven at 160 degrees celcius for about 30 minutes or until the meringue is golden. Allow to cool slightly in the pans before removing to cool further.
• For the custard, heat the milk in a saucepan, add the sugar, custard powder, stirring until thickened. Leave to cool, add lemon zest and juice and mix well. Fold in the whipped cream if using it - I did not use any cream for a change.
• Once the cakes are completely cooled it is time to put it all together. Sandwich the 2 cakes (meringue side up) together with the lemon custard in the middle.

This cake is soooo delicious. There is none left for a photo....I will just have to bake another for Mother's Day tomorrow and post the picture before the  hubby and kids get to the cake....again.
