Tray bake is just a cake baked in a square/rectangular tray so it's easy to slice into even pieces- at least that's my understanding of it!
Parsley- I am NOT making tablet; tablet is the most sickly-sweet DELICIOUS stuff and I know I'll have the will power of a peanut if I make it! But will try the carrot cake recipe and the others- thanks! Most carrot cake here has the 'wrong' sort of icing on it- cream cheese icing is how we like it so will make that one.
Grumpy Goat- I love the look of the granola bars but I fear my littlest will wrinkle her nose at them but I think I'll give them a shot anyway- thanks!
Judging by what came out of my oven last night (before the recipes on here appeared) I add that the recipe will need to be idiot-proof. I iced it in lemon icing (in the hope that that would cover a multitude of sins) and wrapped a weeks worth anyway- if their lunch boxes come back with the slices still in them tonight the dog may be in luck.
