Part 1: A Childhood Favourite That Still Steals the Show

Okay, let’s talk about a traybake that’s got major nostalgic energy. This Chocolate Cornflake Traybake Cake takes me right back to school bake sales, birthday parties, and rainy Saturday afternoons spent in the kitchen. There’s something so satisfying about the crunch of cornflakes mixed with that rich, buttery cocoa syrup—topped off with a thick layer of glossy milk chocolate. It’s classic, simple, and totally irresistible.

The best part? You don’t need any fancy equipment or complicated steps. This is one of those recipes where you toss, stir, press, pour, and chill. Done. It’s practically impossible to mess up, and it always delivers.

Now, some traybakes are just there to be practical. But not this one. This one shows up to the dessert table. It’s got texture, it’s got that sweet-salty balance, and it’s the kind of treat that gets people asking, “Did you make this? Can I have the recipe?”

So if you’re craving a little something sweet (but don’t want to commit to a full-on baking project), or if you’re planning a party and need something that pleases a crowd—this one’s for you.

Let’s get into the details and start stirring up something special!

Ingredients You’ll Need:

Here’s the full list of what goes into this chocolatey masterpiece:

150g cornflakes, lightly crushed
50g desiccated coconut
Pinch of salt
2 tbsp cocoa powder
4 tbsp golden syrup
125g unsalted butter
100g caster sugar
200g milk chocolate (for the topping)
2 tbsp butter (for the topping)

Let’s Start Cooking: Making the Base

Step 1: Preheat & Prepare

Preheat your oven to 180°C (fan) and line a 20cm square baking tin with parchment paper. This is technically a no-bake dessert, but we’re going to give the base a short stint in the oven—just 10 minutes—to help everything hold together a bit more firmly.

Step 2: Melt the Syrup Mixture

In a large saucepan, melt 125g butter, 4 tbsp golden syrup, and 100g caster sugar over low heat. Stir constantly as it melts—you want everything smooth and glossy, with no gritty bits. Let it bubble gently for just a minute or so.

Step 3: Add Cocoa & Salt

Sift in 2 tablespoons of cocoa powder and add a pinch of salt. Stir it all together until you’ve got a rich, dark chocolate syrup that smells incredible.

Step 4: Fold in the Crunch

Take the saucepan off the heat and stir in your lightly crushed cornflakes and desiccated coconut. Use a big wooden spoon or spatula and make sure everything is well coated. It’ll look messy—that’s okay! That rustic, chunky look is part of the charm.

Step 5: Press It In

Tip the mixture into your prepared tin and press it down firmly with the back of a spoon. You want an even layer with a nice, flat surface. Bake it for 10 minutes—this step is optional, but it really helps the bars hold together once chilled.

That’s the base done! Up next: we melt some chocolate (yes please), spread it over the top, and get that traybake into the fridge where the real magic happens.

Part 2: The Chocolatey Finale & Sweet Tips for Success

You’ve got the base pressed in, it smells incredible, and your kitchen probably already feels like the best kind of chocolatey hug. Now comes the satisfying part: pouring that silky milk chocolate topping over everything. And trust me, this part’s as fun to do as it is to eat later.

Step 6: Melt the Chocolate Topping

Melt 200g milk chocolate with 2 tablespoons of butter in a heatproof bowl. You can do this over a pan of gently simmering water (aka a makeshift double boiler), or in the microwave in short bursts, stirring in between.

Once melted and smooth, pour it over the cooled base and spread evenly with a spatula or the back of a spoon. You want to reach all the corners!

Step 7: Chill Until Set

Let it cool at room temperature for a bit, then transfer the whole tray to the fridge for at least 1 hour, or until the chocolate is fully set and the base is firm.

Step 8: Slice & Serve

Once chilled, lift the traybake out of the tin using the parchment paper and slice into 16 squares (or smaller bites if you want more servings). For the cleanest cuts, use a sharp knife and wipe it between slices.

Sweet Tips & Fun Variations

🧊 Chill Thoroughly: Want those perfect, glossy squares? Make sure your traybake is properly chilled before slicing.
🌰 Add-ins Welcome: Stir in chopped nuts, mini marshmallows, or dried fruit for a texture upgrade.

🍫 Change Up the Chocolate: Swap milk for dark chocolate if you prefer a richer taste, or go half-and-half for a balanced bite.
🎉 Party Topping: Before the chocolate sets, sprinkle over fun toppings like rainbow sprinkles, crushed nuts, or mini candies.

There’s just something about that crunch-meets-chocolate combo that makes this traybake totally irresistible. And since it stores so well, it’s great for lunchboxes, coffee breaks, or late-night fridge raids. (Guilty.)

Part 3: FAQs + Final Thoughts

Frequently Asked Questions

1. Do I have to bake the base?
Technically, no—you can skip the oven step. But baking it for 10 minutes helps it hold together better, especially when slicing.

2. Can I use honey instead of golden syrup?
You can, but golden syrup gives it that authentic British flavour and a stickier finish. Honey will work, just slightly different in texture.

3. What kind of chocolate works best for the topping?
Milk chocolate gives the classic flavour, but dark chocolate works beautifully if you want a less sweet, more intense topping.

4. How long will these keep?
Stored in an airtight container in the fridge, they’ll last up to 5 days—if they aren’t devoured first!

5. Can I freeze this traybake?
Yes! Freeze the whole tray or individual squares. Wrap well and freeze for up to 1 month. Thaw in the fridge overnight before serving.

6. Can I make this gluten-free?
Yes—just make sure your cornflakes are certified gluten-free, as some brands may contain traces of gluten.

7. How do I get neat slices?
Use a sharp, non-serrated knife. Run it under hot water and wipe dry before each cut for those clean, professional-looking edges.
