Important question for NI people - what's the story with tray bakes?

[PlanBwastaken]

It seems to pop up ever so often in discussion here, and then posters from Northern Ireland all chime in with their favourites. I still remember the delicious Lumpy-something I had in a little cafe in Antrim.

Is it a Northern thing, or am I way out? And can we have some recipes?

Any recipes please? Especially for lemon options

I like chopped walnuts in my 15s.

I would use 'tray bake' to describe any cake that's make in a bigger 'tray' shaped container (usually a lined meat tin in my case ), as opposed to individual fairy cakes or one 'round cake' to be cut up. Kind of like you used to get for school dinners, where there's a big rectangle of it and you then cut into squares.
Not heard it used to specifically only include 'fridge cakes'.

Love MN - you learn something every day.

Would love the lemon recipe too please, love a good traybake!
