It's likely that you already have the ingredients for this tasty classic retro traybake.
Vegan School Dinners Jam and Coconut Sponge Traybake
The term old school dinners refers to the school dinners of the 70s, 80s, and 90s and the traditional bakes, desserts and meals that were served up during school dinnertimes.
School Dinners Vegan Jam Sponge is a plant-based remake of the old British school dinners favourite. Best of all this cake tastes just as good as the traditional old school bake.
The sponge recipe for this traybake is adapted from a recipe I discovered years ago eggless sponge cake from the book Rose Elliot's Book Of Cakes (1984).
You can check out Rose Elliot's website and some of her recent books over at roseelliot.com.
I bake this traybake for picnics, afternoon tea, pack lunch, and whenever anyone comes to visit.
Jam and coconut sponge is also ideal as part of buffet or pot luck spreads, parties, cake sales, any celebration or special occasion where food is involved.
The topping can be adjusted to your favourite frosting or decoration. Try a thick water icing and finish with vegan hundreds and thousands sprinkles. So pretty.
How To Prepare Vegan Old School Dinners Jam and Coconut Sponge:
Recipe Notes And FAQS
Store this sponge traybake within a cake tin or covered food container for up to 5 days, in a cool, dry area.
Or cover with food safe wrap and store in the refrigerator.
Undecorated jam and coconut sponge can be frozen well wrapped with food and freezer safe wrap for up to 3-4 months.
Remove the wrap before defrosting. Decorate soon after defrosting.
It is traditional to serve jam and coconut sponge with custard especially pink or green!
Usually pink custard would be made with a packet of strawberry or raspberry blancmange mix. But I haven't been able to source one that is dairy free and vegan.
However, for a vegan plant-based custard recipe the following is the one I always use:
Vegan Custard Recipe:
A tasty, easy plant-based custard that can be ready in under 20 minutes and used to compliment all your favourite vegan puddings.
- 2 tablespoons of custard powder
- 2-3 tablespoon of granulated sugar or any sugar, syrup or sweetener of choice
- 400-500 ml (2 cups) of plant-based milk. (The amount depends on whether you prefer a thin or thicker custard).
For a traditional pink custard vegetarian recipe, check this one here at littlestuff.co.uk.
However, the link to the little stuff recipe isn't vegan so only suitable for the vegetarians, etc in your life! Unless of course you can source a vegan blancmange mix and use plant-based milk.
You could always try adding some vegan-friendly pink food colouring to the vegan custard recipe above. I have tried several times to colour the custard pink but the colour was more peachy!

Jam and coconut topping:

- Un-decorated sponge can be frozen, well wrapped, for 3-4 months. Defrost at room temperature, with wrappings removed. Once at room temperature toppings can be added.
- For an iced topping with sprinkles: Sieve about 12 tablespoons of sieved icing sugar (powdered sugar) and mix with a few drops of water at a time until the desired consistency. Spread over your sponge. Scatter sprinkles over. If only decorating half the traybake with icing just use about 6 tablespoons of icing sugar.
- If your icing is too thin just add some more icing sugar and mix until its how you like it.
- For icing that is too thick add tiny drops of water and mix.
- For a lemon traybake, add some grated lemon zest to the sponge mix. Use lemon juice to prepare the icing instead of the water. Decorate with sprinkles or more lemon zest.
