Cornflour sponge cake

l've made this cake for over 65 years from a recipe from my Grandma's 1934 cookery book .

If you make a classic sponge cake -
4 eggs
8 ozs soft butter
8 ozs castor sugar
I teaspoonful baking powder
I teaspoonful vanilla essence
8 ozs flour -
And replace 2ozs of the flour with cornflour - you'll get a very nice balance -not too dry , but different .

I used to add Camp
Coffee and decorate it with walnuts for a change .

I ggled cornflour sponge cake and found this:

I have my Grandma's old recipe for 'Sand Cake', which might be a similar thing - I seem to remember its crust possibly being crunchy.
