A Taste of Sweet School-Day Nostalgia

There’s something about this Classic Jam and Coconut Traybake that takes you right back to your childhood lunch breaks, sitting at a school canteen table with a tray and a cup of lukewarm tea. And then—there it was: a soft vanilla sponge topped with a glossy layer of strawberry jam and a snowy sprinkle of desiccated coconut. Simple, sweet, and always the highlight of the day.

This recipe is a true British classic, and it’s one of those bakes that never goes out of style. Whether you remember it from your school days or you’re just discovering it, the combination of tender sponge, fruity jam, and coconut is comfort food at its finest. It’s easy, it’s quick, and it feeds a crowd—what more could you ask for?

I first baked this traybake on a whim when I stumbled across an old handwritten recipe tucked inside my mum’s cookbook. The moment I pulled it from the oven and sliced into those golden squares, the smell alone brought back a wave of childhood memories. It’s the kind of bake that feels familiar and special all at once.

So, whether you’re baking for a birthday, tea party, school fundraiser, or just a quiet afternoon treat, this is a winner. Let’s get stuck in.

Ingredients

For the Sponge:

• 200g unsalted butter, softened

• 200g caster sugar

• 200g self-raising flour

• 2 tbsp milk

• 1 tsp vanilla extract

For the Topping:

• 4 tbsp strawberry jam

• 50g desiccated coconut

Step 1: Preheat the Oven

Start by preheating your oven to 180°C (160°C fan) / 350°F. Grease and line a 20cm x 30cm rectangular baking tin with baking parchment, making sure there’s some overhang for easy lifting later.

---

Step 2: Cream Butter and Sugar

In a large mixing bowl, cream together the butter and caster sugar until light, pale, and fluffy. This will give your sponge a lovely soft texture, so don’t rush this step—take a good 2–3 minutes with an electric mixer or a sturdy wooden spoon.

---

Step 3: Add the Eggs

Crack in the eggs one at a time, beating well after each addition. If the mixture starts to look a little curdled, don’t worry—just add a spoonful of flour to bring it back together.

---

Step 4: Fold in the Dry Ingredients

Sift in the self-raising flour and gently fold it into the wet mixture using a spatula or large spoon. Be careful not to overmix—you just want everything combined. Then stir in the vanilla extract and milk to loosen the batter.

---

Step 5: Bake the Sponge

Pour the batter into your prepared baking tin and smooth the top with a spatula. Bake in the centre of your preheated oven for 25–30 minutes, or until a skewer inserted into the centre comes out clean.

Let the cake cool completely in the tin. This is important—if the cake is warm when you add the jam, it’ll melt and soak in too much.

Jam, Coconut & All the Finishing Touches

Now that your sponge is baked and cooled, it’s time to dress it up. This part is quick, easy, and super satisfying—because who doesn’t love slathering on a sweet layer of jam?

---

Step 6: Add the Jam

Spoon 4 tablespoons of strawberry jam over the top of the cooled sponge. Use the back of a spoon or a small offset spatula to spread it evenly across the entire surface. You want a generous layer here—don’t be shy!

Tip: Warm the jam slightly in the microwave for 10–15 seconds to make it easier to spread.

---

Step 7: Sprinkle the Coconut

Next, scatter 50g of desiccated coconut evenly over the top of the jam-covered sponge. It’ll stick nicely and create that signature snowy finish that makes this traybake so nostalgic.

---

Step 8: Slice and Serve

Once everything’s set, lift the cake out of the tin using the parchment and cut it into 12 generous squares. Serve with a cuppa or wrap them up in lunchboxes for a sweet midweek treat.

---

Optional Variations:

• Use raspberry jam or apricot jam for a different twist.

• Add a layer of buttercream under the jam for a more indulgent finish.

• Top with glacé cherries for a retro school-dinner look.

FAQ & Final Thoughts

Frequently Asked Questions

1. Can I use margarine instead of butter?
Yes, baking margarine works well and will still give you a light sponge texture.

2. How should I store the traybake?
Store in an airtight container at room temperature for up to 4 days. It’s best eaten within the first 2–3 for ultimate freshness.

3. Can I freeze it?
Absolutely! Freeze slices individually wrapped for up to 2 months. Defrost at room temperature before serving.

4. Can I make this gluten-free?
Yes, substitute the self-raising flour with a gluten-free self-raising blend. Add ¼ tsp of xanthan gum if your blend doesn’t contain it.

5. What other jam flavors work?
Raspberry, apricot, or even blackcurrant jam all work beautifully with the coconut topping.

6. Can I make it as cupcakes instead?
Sure! Spoon the batter into lined muffin tins (fill ¾ full) and bake for 15–18 minutes. Once cooled, top each with jam and coconut.

7. Is it overly sweet?
It’s sweet, yes, but balanced with the vanilla sponge and subtle coconut. You can slightly reduce the sugar if preferred.
