Old School Jam and Coconut Sponge

A nostalgic gluten-free traybake with light sponge cake topped with warm sticky raspberry or strawberry jam and generous sprinkle of desiccated coconut.

This old school jam and coconut sponge takes me right back to primary school dinners - except this version's a fair bit better than what we got back then. It's a proper classic: a light gluten-free sponge topped with warm, sticky jam and a generous sprinkle of coconut.

The recipe itself couldn't be simpler. You'll make a basic sponge using the classic creaming method, where butter and sugar are beaten together until fluffy before adding eggs and flour. The gluten-free flour works brilliantly here - in fact, most people wouldn't notice the difference in the finished cake.

Whether you need to avoid gluten or not, everyone can enjoy a proper slice of nostalgic traybake.

That's what makes this recipe particularly special. The gluten-free flour creates the same light texture as a traditional sponge.

What makes this cake so good is how the warm jam slightly melts into the sponge, while the coconut adds a lovely texture and subtle sweetness. It's brilliant with a cup of tea, but if you're feeling indulgent, serve it with custard like we used to get at school.

This is the kind of cake that works just as well at a bake sale as it does for dessert after Sunday dinner. The jam topping creates a sweet, sticky layer that soaks into the top of the sponge slightly, giving you that perfect balance of moist cake and fruity sweetness. The coconut adds a gentle crunch and tropical note that complements the jam beautifully.

You can use either raspberry or strawberry jam depending on what you prefer, or whatever you have in the cupboard. Both work equally well, though raspberry tends to have a slightly sharper flavour that cuts through the sweetness nicely.

Storage

Store in an airtight tin for up to 5 days. The sponge keeps well and actually improves slightly after a day as the jam soaks in.

Variations

Try using different jam flavours like apricot or blackcurrant. For a richer version, add a layer of buttercream before the jam.
