fat free sponge with full fat filling

...a slightly contradictory recipe but it works well.  A light and fluffy fat free sponge - almost virtuous - filled with full fat whipped cream and jam!  You could of course substitute a lower fat filling such as low fat creme fraiche or mascarpone and fresh fruit however as I am also doing my bit to prevent food waste (I had a pot of double cream that needed to be used up) that is what I am using.  So if you needed another reason that baking this was a good idea this is not only delicious but also environmentally friendly ;-)

Just off to do my run now......happy baking :-)

ingredients:

4 eggs
180g caster sugar
90g plain flour
1 tsp baking powder
1 tsp vanilla extract
pinch of salt

filling:

3-4 tbs fruit jam (I used plum)
250ml double cream

method:

• preheat the oven to 180C and grease and line 2 8" sandwich tins.  
• whisk the eggs and sugar together for at least 4-5 minutes with an electric whisk - until it is has doubled in size and is light and airy.  
• sieve in the flour, baking powder and salt and add the vanilla extract - fold in gently with a metal spoon - being careful not to knock the air out.  
• pour the mixture equally between the 2 tins and bake for approximately 15-20 minutes. It is done when slightly springy to touch.  
• remove carefully from the tins and leave on a wire rack until completely cool.  
• for the filling - spread the jam on one of the cakes then whisk up the cream until thick.  
• spread the cream over the jam before sandwiching with the other cake 
• sprinkle with icing sugar and it is ready!  Enjoy with a lovely cup of tea.
