So, this jammy coconut loaf cake has been on my list for AGES, and I am so happy it is finally here for you guys! The sponge itself is soft, buttery and properly moist, with desiccated coconut running all the way through for that gentle nutty flavour.

The raspberry jam on top does two lovely things, it adds a sweet-sharp fruity hit against the mellow coconut, and it keeps every slice feeling extra moist. Honestly it is the kind of everyday bake I make just for myself with a cup of tea, but it is pretty enough to pop on the table for afternoon tea or a birthday too. I have baked this one more times than I can count because I adore raspberry jam and coconut together, and it works every single time.

Baking in a loaf tin

You want a 2lb loaf tin for this one. The long, deep shape gives you a tall, even sponge and a lovely flat surface for spreading all that jam, and it bakes up into neat, sliceable pieces. You can use half of the mixture in a 1lb loaf tin, or split the mixture into two 1lb loaf tins and bake for less time.

I use my trusty Tala 2lb loaf tin, but any 2lb tin you already have will do the job perfectly. Make sure not to over fill your tin however as they really can vary in size – I recommend only going to 2/3 full, and making cupcakes with spare mixture if your tin does come up smaller than mine.

A simple sponge

The actual sponge for this jammy coconut loaf cake recipe is incredibly simple – for eggs (I nearly always use medium in my house), with self raising flour, baking spread/unsalted butter, and sugar. As this is meant to be a light cake, I used caster sugar for a lighter flavour! 

When I am creating the base sponge mix, I weigh my 4 medium eggs in their shells to get a weight. Say its 211g, I then use 211g of self raising flour, baking spread, and caster sugar for the sponge – then, I add in the desiccated coconut and mix! 

Baking with coconut 

The coconut flavour all comes from desiccated coconut. It is so light that the 75g looks like a lot going into the sponge, but it melts into the crumb as it bakes and gives you a soft, gorgeously moist texture rather than anything gritty.

If you fancy a stronger coconut hit you can nudge the sponge coconut up to 100g, or for something more subtle just leave the sprinkle off the top. I use it in both the sponge and the topping because I love it, but it is easy to tweak to your taste.

Decoration

The good thing is with this bake is once the sponge has been baked and cooled… it’s SO EASY TO DECORATE! Honestly all you have to do is top the cake with your chosen jam (like I said, I use raspberry), and then sprinkle on some desiccated coconut! 

If you love this one, you might also want to try my original coconut loaf cake. The difference is simple: that one is a plain coconut sponge, whilst this jammy version adds the raspberry jam and coconut topping for a fruitier, moister finish. Serve this beauty just as it is, or with a bit of custard for the ultimate dream! It keeps lovely and moist for 4 to 5 days in an airtight container at room temperature. If you have any questions about the recipe, leave them below in the comments! Enjoy! x

Ingredients

Cake

  • 200 g unsalted butter
  • 200 g caster sugar
  • 200 g self raising flour
  • 4 medium eggs
  • 75 g desiccated coconut

Decoration

  • 200 g raspberry jam
  • 25 g desiccated coconut

Instructions

For the Cake

  • Preheat the oven to 180ºC/160ºC Fan, and line your 2lb loaf tin with parchment paper!
  • Beat together the unsalted butter or baking spread and the caster sugar until light and fluffy.
  • Add in the self raising flour, eggs and desiccated coconut and beat again until smooth and combined.
  • Pour the mix into the tin, and bake the cake in the oven for 50-55+ minutes! Test the cake with a skewer (and also listen for a bubbling/crackling sound as this noise means its not finished baking)
  • Leave the cake to cool in the tin.

For the Decoration

  • Once the cake has cooled fully, carefully spread the jam on the top of the cake.
  • Sprinkle on the desiccated coconut and enjoy!

Notes

  • I recommend using this 2lb loaf tin
  • Use a cake skewer to see if it’s done – it should come out clean. Also listen to the cake for a bubbling/crackling sound as this sound means its not finished baking and needs a bit longer! 
  • Loaf cakes can sometimes take slightly longer to bake in some ovens (if the oven temp is off) as they act similarly to bundt cakes!
  • You can use any flavour jam you like!
  • This cake lasts 4-5+ days at room temp!

    Hello Jane….absolute fan of your recipes….and been asked to do this one as a leaving cake at work….do you reckon it would work ok in an 8″ round tin? Any tips if so! Thinking of a double layer… many thanks 😊

    Hello Jane
    Absolute fan of your recipes….and been asked to use this one for a leaving cake at work….would you recommend a size of circular tin that it could work in? 8″? Wondering if to do a double layer sandwiched with the jam & coconut in the middle too?!

    Hiah, Would you be able to swap the SR flour for coconut pour please? If so what weights would you use and I’d guess you’d need to add baking powder?
    Thank you so much

    • Jane's Patisserie on June 10, 2021 at 11:15 am

      Hiya I have never baked with this so I don’t know, it wouldn’t just be a straight swap xx

    • Jane's Patisserie on June 7, 2021 at 4:21 pm

      aww thank you so much, hahaha I love it xx



  7. Jayne on June 5, 2021 at 8:30 pm

    Can you use a different sugar rather than caster sugar?

    • Jane's Patisserie on June 10, 2021 at 10:59 am

      Hiya, for best results use caster sugar but you can use light brown or dark brown soft sugars if you wanted x



    • Karen on November 13, 2024 at 8:31 pm

      Absolutely perfect! Thankyou for the recipe!



  8. Em on June 5, 2021 at 4:29 pm

    Oh my, just made this.. the lightest, fluffiest loaf cake I’ve ever made and the mixture was enough for my 2lb loaf tin and 6 little cupcakes – win win! Thanks for posting this – new favourite 😍

    • Jane's Patisserie on June 7, 2021 at 4:23 pm

      Aww thank you for such a lovely review I am so pleased you love it xx



  9. Megan on June 5, 2021 at 9:50 am

    If I was to make this into a traybake how would I alter the recipe?

    Really looking forward to trying this recipe

  10. Patty on June 5, 2021 at 9:50 am

    This looks lovely! Do you also think splitting the loaf across and adding a buttercream filling in the centre might work?

    • Jane's Patisserie on June 10, 2021 at 10:52 am

      Hey, yes could do!x



  11. Samantha Hutchinson on June 5, 2021 at 9:21 am

    Hi Jane, could this be done as a tray bake?

  12. Debs on June 5, 2021 at 8:49 am

    Hi Jane. This sounds like an easy and delicious cake 😋 and I’m eager to head to the kitchen right now and run one up. Just wondering if it could be more yummy by sprinkling toasted coconut 🥥 onto the raspberry jam or jam of choice {🍓🍒} or could this spoil the overall flavour and simplicity and one of the reasons why you didn’t? Best wishes. Debs

    • Jane's Patisserie on June 7, 2021 at 4:24 pm

      Hiya, I haven’t tried this but it is definetly worth a go if you would like!xx
