It's finally starting to feel a bit like summer in the UK, so this week, I got started on my no-bake summer treats! Hurrah!

Inspired by the lime and ginger cheesecake I made a couple of years ago, this ginger and lime rocky road has a similar summery feel and delicious flavour. It's quick to make with only 5 ingredients, and there's absolutely no baking involved!

Ingredients

White chocolate: I used white chocolate to create the base of my rocky road, not only for the neutral colour but also because it picks up the lime flavour better than milk or dark chocolate.
Gingernut biscuits: These spicy biscuits pair perfectly with the super sweet chocolate, creating a nice balance. I used 200g. If you don't have gingernuts, you could use another type of biscuit (such as digestives), then add sweetened crystallised ginger for the flavour.
Mini marshmallows: You can't make a good rocky road without these! I used 80g, which gave a nice chew without overpowering the mixture.
Lime zest: Because this recipe uses quite a lot of white chocolate for the base, we'll need to use quite a lot of lime zest too, to really get that flavour to shine through! I used the zest of 4 small limes, plus a little extra for the top.
Lime marmalade: This is optional but swirling some lime marmalade (or lime curd) on top is great for some extra flavour. I got mine from Asda.

Equipment

8x8 tin: I recommend this size of tin, which will give you 9 very chunky slices or 16 smaller squares. If you need to use a larger tin, use my cake tin converter to adjust the recipe to fit; otherwise, you'll end up with thin slices.
Baking paper: Line the tin well, up the sides too, to prevent sticking.
Saucepan: Or a heatproof bowl, to melt the white chocolate.
Microplane: Or a fine grater, for the lime zest.
Mixing bowl: A large one, to mix everything together.
Utensils: You'll need a wooden spoon for mixing the ingredients, a small spoon or spatula for pressing the mixture into the tin, a toothpick for swirling the marmalade, and a sharp knife for cutting.

How to make ginger and lime rocky road

Step 1: Add 200g gingernut biscuits to a large bowl, then use your hands to break them up into medium-sized chunks. We don't want them to be too small- around ¾-inch pieces are perfect.

Step 2: Add 80g of mini marshmallows and the zest of 4 limes to the bowl. Mix briefly to combine them with the biscuit pieces.

Step 3: Pour 500g of melted white chocolate into the bowl. Mix well, until all of the dry ingredients are evenly coated and there's no chocolate left pooling at the bottom.

Step 4: Spoon the mixture into your lined tin and press it down firmly into place. Then spoon over 2-3 teaspoons of lime marmalade and gently swirl it in with a toothpick or butter knife.

Step 5: Top with more lime zest, biscuit pieces and marshmallows.

Step 6: Pop the whole thing in the fridge for 3 hours to set, then cut it into slices and enjoy!

Top tips

For a stronger lime flavour, add a teaspoon or two of lime extract to the melted white chocolate.
To get clean slices, let the rocky road come to room temperature before you cut it. Use a warm knife and press down gently to prevent breakage.
Add a handful of chewy lime sweets to the mixture for extra texture and flavour. You could use Skittles, Starburst, candy lime slices, or even some chunks of lime jelly.

FAQs

How long will ginger and lime rocky road last?

This will keep well in the fridge for up to 1 week. Keep it stored in an airtight container to ensure the biscuits stay nice and crunchy!

Can I freeze this?

Yes, you can freeze the slices for up to 3 months in an airtight container. Alternatively, freeze the entire slab (after it's set) wrapped tightly in clingfilm. To defrost, transfer it to the fridge overnight or let it sit at room temperature for an hour or two. Do not refreeze.

Can I use milk chocolate instead?

Yes, this will work, but the lime flavour might not taste as strong as it does with the white chocolate. If you're adding chewy lime sweets then milk or dark chocolate will be totally fine!
