Found em!
In the row of shops opposite the church in trinity square are two small alleyways,with shops in, easily walked passed but the alleyway nearest town has a handmade chocolates shop down it. The giant walnut whips are not as big as i thought. But they are about 4 inches high, so some complicated maths suggests they've substantially more volume than the originals, only the white filling ones but she does coffee ones at christmas apparently.sold individuslly but a box of 4 is under a fiver.
I used to have a chocolate shop but it melted...
