A problem with gingerbread puddings!

Dear Lindsey

I’ve tried to make sticky gingerbread puddings unsuccessfully now three times in a row!

I follow the recipe exactly and I’ve never had problems with any of Delia’s recipes before. I cook the puddings until they are full and springy in the middle for the full amount of time but after a few minutes out of the oven they shrink dramatically and become very dense.

What am I doing wrong? I’ve tried chopping up the apples and ginger larger and smaller and put them in the oven for a bit longer but they turn out exactly the same - dense and flat . I’ve cooked Delia’s similar little sticky toffee puddings lots of times and they always turn out light a well risen. Many thanks in advance for any advice!
