Extra large tray bake - advice needed please!

Asda sells tray bake disposable trays as wells as non stick. May be simpler to use the disposables.

Whiff

Starof this is a perfect filling and can be used as topping for people who don't like buttercream . It very old so only in ounces.

For a cake your size I woud do 4-6 times quality

Chocolate fudge icing

1oz melted spread
2 tbsp milk
1oz cocoa powder
3oz icing sugar

Mix all ingredients into melted spread. Have been using this recipe for over 30 years. Not met anyone who doesn't like it.

Whiff, do you think your recipe would work with butter instead of spread?

Skye yes it would. As it said butter when I wrote it down all those years ago and when spreads started to taste nice I put spread by the side of butter.

I have used it to sandwich Viennese biscuits together instead of jam and buttercream. As the biscuits are very rich the fudge icing tastes better than jam and buttercream it should be.

Only add one tbsp of milk to start with as it depends on how old the icing sugar and cocoa powder are . I found sometimes 1 was enough it's always easier to add extra but you can't take it away if it's to runny.

Thank you, Whiff. That is all helpful.

I used to do tray bakes weekly when my daughter started up a mother and toddler group on Saturday mornings. I bought a roasting tray from Poundland and some liners that I cut to size. Doubled up the quantities and lowered the normal temperature. Lemon drizzle always went down well especially if it had some chopped stem ginger in syrup as well.
