Spread on top of one layer - half of the apricot puree.
Cover with second layer.
Cut the cake in 2 inch by 1 inch pieces and arrange them in the bottom of large glass serving bowl.
Pour liquor over cake and spread the rest of apricot puree on top.
Custard[]
Mix Sugar and corn flour in a glass bowl with a little milk till very smooth; add the rest of the milk.
Cover and microwave for 3-4 minutes or until it nearly thickens.
Every few seconds, mix with a hand whisker.
Add 1 egg at a time and beat well with the whisker.
If you have a double saucepan (and you have the time), continue to stir continuously over boiling water for 10 minutes or, just be careful, and continue to microwave for another 1 -2 minutes, but you will have to beat with the whisker every 2 seconds so it will not get to be an omelet.
