This no-fail Thermomix rocky road is made with creamy white chocolate, fluffy marshmallows, glacé cherries and pistachios, and takes just 10 minutes to prepare before setting in the fridge for 3 hours.
By gently heating and stirring the white chocolate at a steady 50°C, the Thermomix keeps it smooth and well-behaved - no seizing, no graininess, and no burnt chocolate stuck to the base of the bowl.
White chocolate rocky road is especially popular during the festive season, so much so that it's often referred to as white Christmas rocky road. This recipe is perfect for gifting, as it slices neatly and is easy to wrap up, alongside other reliable homemade treats such as my creamy caramel fudge.

Recipe Ingredients
Note: The full quantities are shown in the recipe card below.
- White chocolate - use white chocolate melts from the baking aisle for the most reliable results. These are designed to be melted and will not go grainy. An exception is Lindt white chocolate, which melts very well.
- Marshmallows - large marshmallows cut in half are just the right size to ensure a gooey mouthful in every bite.
- Glacé cherries - bright red, sticky, and very Christmasy. See substitutions below.
- Pistachios - no need to chop them up beforehand, except for a few for the topping. See substitutions below.
- Vegetable oil - choose a neutral flavour oil like sunflower or canola. The addition of vegetable oil helps keep the white chocolate smooth and makes the rocky road easier to cut once set.
Substitutions
Glacé cherries - can be substituted for dried cranberries or dried cherries. If you're in Australia, you could also use Allen's Ripe Raspberry lollies.
Pistachios - you can use other nuts such as almonds, cashews, hazelnuts, peanuts, macadamia nuts, or pecans.
Step-by-Step Directions
Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.
- Line a baking tin, with overhangs on opposite sides to make it easy to lift the rocky road out. Have pistachios, marshmallows and glacé cherries weighed and ready to add. Reserve about 10 cherries and a tablespoon of pistachios for the rocky road topping. Roughly chop the reserved pistachios into small pieces so they scatter neatly over the surface.
- Add the white chocolate to the Thermomix bowl and melt for 3 minutes, on 50°C, speed 1. Scrape down the bowl, then melt for a further 2 minutes, 50°C, speed 2.
- Work quickly and add the mix-ins, then gently mix for 10 seconds on reverse speed 2.
- Give the mixture a good stir with a spatula to ensure everything is evenly coated with white chocolate.
- Quickly tip the mixture into the prepared tin before it starts to set. Press down and smooth over the top.
- Scatter over the reserved cherries and pistachios and gently press them into the surface. Refrigerate for 3 hours, or until set.
Recipe Tips
- Use the right melting chocolate from the baking aisle.
- Keep the temperature at 50°C when melting the white chocolate.
- Leave the measuring cup off while melting the chocolate to prevent condensation dripping in and causing it to seize.
- Work quickly when adding the mix-ins, as they bring the temperature of the chocolate down and it begins to set.
- For extra crunch, toast the pistachios in a frying pan over low heat.
- Leave overhangs when lining the tin to make it easier to lift the rocky road out once set.
Storage
Store the rocky road in an airtight container in the fridge for 1-2 weeks.
Common Questions
No, doubling the recipe isn't recommended, as the Thermomix bowl isn't large enough to melt and mix the chocolate evenly.
This can happen if the wrong type of white chocolate is used. Use white chocolate melts and not cooking chocolate.
Over-chilling can make the rocky road firm. Let it sit at room temperature for 5-10 minutes before slicing.
