Doubling up a recipe

[sherrardk]

If I double up the quantities it his recipe http://www.bbcgoodfoo...school-treacle-sponge

How will it alter the cooking time (or won't it), thanks.

All depends on the size of tin used - if the tin you are going to use makes it no deeper than the recipe shows it should take the same time (roughly) but if it's going to be deeper you might find the middle still a bit sticky after alloted time so give it another 5-10 mins and then test the middle with a skewer - if it comes out clean it's cooked

The other solution is to cook them in smaller individual size moulds like cups or madalin moulds and speed up the cooking and saving money, easier to freeze any remaining serves too
