What you'll need

Here are all of the ingredients for Cornflake rocky road...

Chocolate: For this recipe, you'll want to use semi-sweet chocolate. If you use milk chocolate, the extra sugar will cause the mixture to seize. I typically use something like Asda Just Essentials dark chocolate but most cheaper 'dark' chocolate will work.
Butter: Butter will help to soften the chocolate after it's set, meaning you won't be munching on a solid block of chocolate! I recommend using unsalted butter unless you particularly like the sweet and salty mix.
Golden syrup: Golden syrup will help the chocolate and the butter mix together more easily without splitting or seizing. You can swap it out for an equal amount of agave nectar or honey if you're in a pinch.
Digestive biscuits: Some crunchy biscuits are a must-have for any good rocky road recipe. I like to use digestives but you can use any other kind of biscuits that you like, such as shortbread or rich tea biscuits.
Cornflakes: The star of the show, Cornflakes! I used 60g of Cornflakes in total, which gave a nice crunch and flavour without totally overpowering the other ingredients. I used Kellogg's Cornflakes but feel free to use any brand you like.
Mini marshmallows: You'll need 100g of mini marshmallows but you can just chop up some regular-sized marshmallows if that's all you have. Marshmallows will add extra sweetness, a chewy texture, and a pop of colour.

Equipment

Aside from the ingredients, you'll also need the following kitchen equipment:

Baking tin: An 8x8-inch tin is the best size to use for a thick rocky road slice but an 8x10-inch tin will work too. If you want to use larger tins such as 9x11 or 9x12, I'd recommend increasing the ingredients too- you can do this using my cake pan converter tool.
Greaseproof paper: Or baking paper, to stop the rocky road from sticking to the tin. To make the rocky road easier to remove, leave a bit of baking paper hanging over each edge.
Bowls and utensils: For this recipe, you'll need a large bowl and a wooden spoon for mixing, and a sharp knife for cutting. To press the mixture firmly into your tin, I recommend using either the back of a metal spoon or a small rubber spatula- these won't stick to the mixture as much as the wooden spoon will.
Saucepan: To melt the chocolate, butter and golden syrup together. You can do this in the microwave too if you have a heatproof bowl. Just make sure to take it out and stir it every 30 seconds or so to prevent burning or seizing.
Kitchen scales: To ensure your measurements are accurate, use a kitchen scale to weigh out the ingredients. I tend not to use cups when baking because they can differ so much from person to person.

How to make Cornflake rocky road

Step 1: First, start by lining an 8x8x3-inch tin with baking paper. Set it aside for now, ready for your mixture to go in later.

Step 2: Next, add 300g of semi-sweet chocolate to a saucepan along with 100g of unsalted butter and 3 tablespoons of golden syrup. Place the saucepan over low heat on the stove and stir gently until there are no lumps of chocolate or butter left.

If you prefer, you can also melt these ingredients in a heatproof bowl in the microwave. You'll need to take the bowl out and stir every 20-30 seconds, otherwise the mixture can burn or seize.

Step 3: Now it's time for the dry ingredients. Add 150g of digestive biscuits to a large mixing bowl then crush them into medium-sized chunks using your hands. Don't make the pieces too small!

Step 4: Add 60g of Cornflakes and 100g of mini marshmallows to the bowl and mix briefly to combine.

Step 5: Now pour the melted chocolate/butter mixture from earlier into the bowl with the dry ingredients. Mix well until everything is evenly coated in the chocolate.

Step 6: Transfer the rocky road mixture to your lined tin and press it firmly into place. The more firmly you can press it in, the less likely it is to fall apart once it's set.

Step 7: You're all done! Just pop your rocky road into the fridge for 3 hours to set then cut it into slices and enjoy! I like to cut mine into 16 squares but feel free to make them as big or as small as you like.

Top tips

Let the melted chocolate mixture cool for a few minutes before you add it to the bowl with the rest of the ingredients. This will prevent it from melting the marshmallows.
Use semi-sweet chocolate for best results. Anything that's around 50% cocoa solids should work just fine. Milk chocolate can cause the mixture to split.
