Rocky road Christmas trees

The Thermomix melts butter and chocolate gently without burning, then combines everything into a rich, chewy mixture. Shaped into Christmas trees and decorated with cachous, they make a charming homemade edible gift or party treat.
About this recipe
Rocky road Christmas trees Thermomix TM7 recipes bring the cosiest chocolate tradition of the festive season straight into your all-in-one kitchen machine. These charming no-bake treats start with milk arrowroot biscuits folded through a rich mixture of melted dark chocolate, cocoa powder, condensed milk and butter, dotted with gooey mini marshmallows for that signature rocky road chewiness. The TM7 melting function is the real hero here: its gentle heat control transforms butter and dark chocolate into a glossy, silky base without a single second of burning or seizing, something a bain-marie rarely achieves so reliably. Once chilled and cut into triangular tree shapes, each piece is drizzled with extra chocolate and finished with sparkling cachous that mimic festive baubles. This dessert is perfect for children's Christmas parties, homemade gift boxes, or an afternoon baking session with little helpers who love pressing the decorations into place. Searching for easy festive sweets means finding a recipe that works without an oven, and this one delivers exactly that.
Preparation tips
- Press the rocky road mixture firmly into a lined tin before chilling so the Christmas tree shapes hold together neatly when cut; a second sheet of baking paper on top helps you compact it evenly.
- Cut the chilled slab into triangles with a warm knife for clean edges, then insert a small pretzel stick or piece of biscuit at the base as an edible trunk for each tree.
- Store the finished trees in an airtight container in the fridge between layers of baking paper; the condensed milk base keeps them chewy for up to a week, and children can decorate the cachous themselves.
Recipe variations
- Gluten-free version: replace the milk arrowroot biscuits with gluten-free plain biscuits and use certified gluten-free chocolate; the marshmallows, condensed milk and cocoa mixture stays exactly the same.
- Festive white chocolate variant: swap the dark chocolate for white chocolate and tint the trees with a dusting of green-coloured sugar; add dried cranberries and pistachios alongside the marshmallows for a red-and-green Christmas look.
