step 1
In a bowl cream the Butter and Sugar together untill smooth.
step 2
Add in the Eggs, and beat quickly so that it does not curdle (You could add a tbsp of flour at this point - if you are worried about it curdling).
step 3
Once the Eggs are combined, add in all of the Flour, and combine together, try to get as much air in the mixture as possible.
step 4
Grease a separate bowl with a little butter. In the bottom of the bowl put in your topping, (eg - Jam).
step 5
Once the Jam is in the bottom, add the sponge mixture on top of the Jam and level out slightly.
step 6
Cover with cling film or a plate and microwave for about 6-8 minutes (Time may vary on individual microwaves - so if you think it needs more time dont worry - you cant over cook the sponge - just be carefull if you have used chocolate spread this can burn)
step 7
Once cooked remove the cling film or plate (be carefull it will be hot). Place a large plate over the top of the bowl - holding the bowl and plate together - flip the bowl upside down and the sponge should land on the plate. Take the bowl off, cut into 4 and serve with custard.
