Sunday Recipe - School Dinners Jam and Coconut Sponge Squares. (2024)

Posted By Laura in Family Recipes, Retro School Dinners Recipes | 50 comments

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 – 40minutes

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.

A 70's child, I’ve been married for a Very Long Time, and appear to have made four children, and collected one large and useless dog along the way.I work, I have four children, I have a dog… ergo, I do not do dusting or ironing.I began LittleStuff back in (gulp) 2004.I like huge mugs of tea. And Coffee. And Cake. And a steaming cone of crispy fresh fluffy chips, smothered in salt and vinegar. #healthyeaterWhen I grow up I am going to be quietly graceful, organised and wear lipstick every day. In the meantime I *may* have a slight butterfly-brain issue.

          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

            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?

    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

      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.

      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.

      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 :)

    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.

    Absolutely delicious. I also did mine with a cooked pastry base, spread with raspberry jam and then the sponge on top. Takes longer but worthwhile.
