Sunday Recipe – School Dinners Jam and Coconut Sponge Squares.

One of my own personal favourites, and as usual so easy you can whip it up yourself or easily cope with small helpers too. My bigger helpers can manage this one on their own. Of course, tray bakes are ideal for school/cubs/scouts/brownies/guides cake requests, but just as good when feeding a hungry horde. If you’re doing this one the proper school dinner way, it MUST be served with a lashing amount of thick custard of choice (try our school dinners pink custard perhaps).

Time to prep – 10 minutes

Time to Bake – 40 minutes

What you need:

  • 8 oz butter
  • 8 oz sugar
  • 10 oz SR flour
  • 2 tsp baking powder
  • 4 eggs
  • Jar of Red jam (Yes it must be red, it’s the rules. Seedless raspberry is best, we think)
  • Pack of Desiccated Coconut

What you do:

  1. Preheat the oven to 180ºC, gas mark 4, Fan 170. Grease and line a roasting tin (mine is approx 20cmx30cm) with greaseproof paper.
  2. Beat the butter and sugar together until light and fluffy – an electric mixer is best for this. Add the eggs one at a time beating well with each addition. If the mixture starts to separate, add a little flour with the egg. Fold in the remaining flour and the baking powder.
  3. Pour the mixture into the tin and level the surface. Bake for 35-40 minutes, until well-risen and golden, and coming away from the sides of the tin.
  4. Turn the cake out of the tin and allow to cool on a wire rack.
  5. Spread your jam of choice over the top of the cake and sprinkle with desiccated coconut.
  6. Cut into individual squares – I usually cut mine in 18.
  7. To be VERY popular, serve while still slightly warm with custard of choice.
  8. Sit back and bask in the glow of approval.

You can see our other school dinners recipes here – the cornflake tart is a very popular choice.

        • I’ve made this delicious cake several times but the last one for some reason was a really thick cake mixture so if it happens again do I add water or milk

          Post a Reply
          • I’d add a little milk to loosen it if it’s really thick, but the texture shouldn’t change too much – maybe there was a hiccup in the flour measuring?

        • Trying mine on Friday … Fingers crossed

  10. What an easy cake too make, although when you add the flour I find it gets very heavy and doughy so I add a few drops of milk to help with the folding in, everyone in the house enjoys this cake plus the dogs x

  11. I wanted to know what shelve in the oven I have to bake on please

    Post a Reply
    • I have a fan oven, it’s been a long time since I cooked on gas! But I’d definitely go for the middle shelf, and keep an eye on it towards the end of the cooking time.

    • My pleasure – nothing beats it for a comfort eat!

  12. What size eggs do you use? I just tried medium but it came out like a batter,seemed too thick

    Post a Reply
    • I’d say mine are usually large – I keep chickens, so they aren’t size-graded, but I’m guessing they’d rank as large.
      If your mix is a little thick you can loosen with a splash of milk.

  15. Hi what sugar do you use? Also butter, salted or unsalted or do you use something like stork for cakes? Want to make this cake today

    • Hi Merrell
      I use granulated or caster sugar, whichever is to hand. And I only ever have salted butter in the fridge, so that’s what I use :)

      Post a Reply
  16. I’ve just turned mine out onto a wire rack and I can’t wait for it to cool off so I can add the jam and coconut on top. I’m seriously considering eating it all myself and not telling anyone I made it.
