Why You’ll Love This Recipe
White chocolate rocky road is the sweeter, creamier cousin of traditional dark chocolate rocky road. It’s a no-bake, no-fuss dessert that comes together in 15 minutes flat. The combination of creamy white chocolate, chewy marshmallows, crunchy biscuits, and juicy raspberry candies creates a texture party in every bite.
This recipe is perfect for:
Holiday gifting (wrap in cellophane with a ribbon)
Last-minute potluck desserts
Baking with kids (no heat beyond melting chocolate)
Using up leftover biscuits and marshmallows
Ingredients
Use full-fat, quality ingredients for the best set and flavor.
500g (17.6 oz) white chocolate – chopping block or high-quality melting wafers (avoid cheap chips with stabilizers)
150g (5.3 oz) unsalted butter – cubed
3 tbsp golden syrup or light corn syrup – gives shine and prevents brittleness
200g (7 oz) mini marshmallows – plus extra 50g for pressing into the top
150g (5.3 oz) plain digestive biscuits or graham crackers – roughly broken into 1cm chunks (not crumbs)
100g (3.5 oz) freeze-dried raspberries – or chopped raspberry-flavored jelly candies
80g (2.8 oz) white chocolate chips or white candy melts – for drizzling on top (optional)
Equipment Needed
Large microwave-safe bowl or double boiler
Rubber spatula
20cm x 20cm (8×8 inch) square baking pan
Parchment paper (baking paper)
Kitchen scales or measuring cups
Refrigerator space
Method (Step-by-Step)
Step 1: Prepare the Pan
Line the square baking pan with parchment paper, leaving an overhang on two opposite sides. These “handles” will help you lift the rocky road out later. Time: 2 minutes | Intensity: Low
Step 2: Melt the Base
Place the white chocolate, cubed butter, and golden syrup in your microwave-safe bowl.
Microwave method (easiest): Heat on 50% power for 1 minute. Stir. Heat in 30-second bursts at 50% power, stirring each time, until smooth (total ~2-3 minutes). Do not overheat – white chocolate seizes easily.
Double boiler method: Simmer water in a saucepan, place bowl on top (not touching water), stir frequently until melted.
Intensity: Medium during melting (requires vigilance) | Time: 3 minutes
Step 3: Cool Slightly
Remove the melted mixture from heat and let it sit for 3-4 minutes. It should be warm but not hot. If it’s too hot, it will melt the marshmallows into a puddle instead of leaving chewy pockets. Intensity: Low
Step 4: Combine Dry Ingredients
In a separate large bowl, toss together the broken biscuits, mini marshmallows, and freeze-dried raspberries (or raspberry candies). Reserve about 30g of marshmallows for the top.
Step 5: Mix Everything Together
Pour the cooled white chocolate mixture over the biscuit-marshmallow mix. Fold gently with a rubber spatula until everything is coated. Do not overmix – you want distinct biscuit pieces, not dust.
Step 6: Transfer to Pan
Scrape the mixture into the prepared pan. Press down lightly with the back of a spoon or spatula. Do not compact too hard, or it will become dense like fudge. Sprinkle the reserved marshmallows and extra white chocolate chips over the top, pressing in slightly.
Step 7: Set in Fridge
Refrigerate for at least 2 hours, ideally 3-4 hours or overnight. The rocky road is ready when it feels firm to the touch and no longer sticky.
Intensity: Zero (waiting game) | Time: 2 hours
Step 8: Slice and Serve
Lift the block out using the parchment handles. Place on a cutting board. For 16 large squares: cut into 4 rows by 4 rows. For 32 bite-sized pieces: cut each large square diagonally.
Tip: Warm a large knife under hot water, wipe dry, then slice – this prevents cracking.
Last of the Recipe (Final Pro Tips)
Storage: Store in an airtight container in the refrigerator for up to 2 weeks. It can sit at room temperature for up to 2 hours during serving, but white chocolate softens faster than dark.
Freezing: Freeze in a single layer for 1 hour, then transfer to a freezer bag. Freezes well for up to 3 months. Thaw in the fridge overnight.
Variations:
Nutty rocky road: Add 100g toasted slivered almonds or macadamias.
Christmas version: Swap raspberries for chopped glace cherries and add 1/2 tsp peppermint extract.
Vegan option: Use vegan white chocolate, plant-based butter, vegan marshmallows, and golden syrup.
Troubleshooting: If your mixture is dry and crumbly, you overheated the chocolate. Gently reheat 2 more tablespoons of white chocolate with 1 tsp coconut oil and fold in. If it’s too wet, add 50g more crushed biscuits before setting.
