OLD SCHOOL DINNERS JAM AND COCONUT SPONGE

by

Our School Dinners Jam and Coconut Sponge is a Vegan take on a retro traybake, that is still a very popular family favourite today. This bake dates back to the 60s, 70s, and 80s British school dinners. It is perfect for afternoon tea, tea time, picnics, parties and lunch boxes.

It is so easy and quick to prepare with every day store-cupboard ingredients – despite being an egg-free and dairy-free vanilla sponge you won’t need any fussy ingredients. Also, if you are a home-baker then you’ll likely already have the ingredients for this quick and easy vegan cake.

We have included an easy vegan custard recipe that is perfect with our sponge cake down below in the recipe notes.

  • 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 a water icing topping with sprinkles: Mix about 250 grams [9oz] of icing sugar with about 9 teaspoons of water, adjusting the quantities if necessary, until you have a thick spreadable water icing. Cover the entire cake with the icing spreading it out. Scatter cake sprinkles over.
