About This Recipe – In More Detail

Rocky road bars are a classic, but why not take a traditional rocky road slice to the next level with a different flavour? Just like these Biscoff Rocky Road Bars, I have created something new with this easy Malteser rocky road. 

I have combined the classic ingredients of a rocky road with different flavours. A smooth milk chocolate mixture, chewy marshmallows and glace cherries have been levelled up with added Malted Milk biscuits, and of course, the key ingredient, Maltesers! I have topped it all off with extra Maltesers and a generous drizzle of melted white chocolate. 

It’s simple recipe, that requires no baking, only melting. And, a little patience with the chilling and setting time. Just like this Mars Bar Tray Bake and Our Old-School Coconut Ice. You can get the kids involved in the kitchen and create a recipe together that is ready to set in the baking tin, in under 30 minutes.

Equipment Needed

  • 20cm Square Baking Tin: A square tin is used to set and chill the rocky road mixture. Line it with baking paper for easy removal of the bars later. If you only have a slightly different size to hand like an 18cm square tin or a 23cm tin, that’s ok.
  • Large Mixing Bowl: A large bowl to mix and combine the broken Malted Milk biscuits, chopped cherries, marshmallows, and crushed Maltesers.
  • Medium Saucepan: Used for melting the milk chocolate, butter, and golden syrup over low heat to create the base mixture. If you want to melt the mixture in the microwave instead, be sure to use a heatproof bowl.
  • Rolling Pin: For breaking the Malted Milk biscuits and Maltesers into smaller pieces inside sealed bags.
  • Sealed Plastic Bags: Used to contain and crush the Maltesers and biscuits.
  • Cutting Board: To place the chilled rocky road mixture for slicing into bars.
  • Baking Paper: Lining the baking tin with greaseproof paper for easy removal of the set rocky road bars.
  • Large, Sharp Knife: For slicing the chilled and set rocky road mixture into individual bars.

Ingredients

  • Malted Milk Biscuits: Malt biscuits provide texture and a biscuit base when broken into pieces, adding crunch and flavour to the rocky road bars.
  • Mini Marshmallows: Contribute chewiness, texture, and an element of colour to the bars. You can choose white marshmallows or multi-coloured ones.
  • Milk Chocolate: Forms the base of the mixture when melted, binding all ingredients together and providing the main chocolatey flavour.
  • Unsalted Butter: Combined with melted chocolate and golden syrup, it adds richness and helps create a smooth and glossy texture.
  • Golden Syrup: Acts as a sweetener and binder, aiding in combining the ingredients while adding a subtle caramel-like flavour. If you can’t find it at the supermarket or grocery store, you can make your own golden syrup.
  • Glace Cherries: Provide pops of colour, texture, and a sweet, fruity flavour to the rocky road bars when chopped into small pieces.
  • Maltesers: Offer additional crunch, flavour, and a malted milk chocolate taste to the bars. They’re crushed for even distribution within the mixture and left whole for topping.
  • White Chocolate: Used for drizzling on top of the set mixture, adding visual appeal and a contrasting flavour to the milk chocolate base.

Additions and Substitutions

Substitutions:

  • Malted Milk Biscuits: Substitute with digestive biscuits, graham crackers, or any other plain, crunchy biscuit for a different texture. You could try Maltesers Biscuits too, if you can find them in the supermarket.
  • Mini Marshmallows: Use larger marshmallows or regular marshmallows cut into smaller pieces.
  • Milk Chocolate: Experiment with dark chocolate or a combination of dark and milk chocolate for a richer flavour.
  • Golden Syrup: Corn syrup, maple syrup, or honey can substitute golden syrup for a similar binding sweetness.
  • Glace Cherries: Dried cranberries, chopped dried apricots, raisins or mixed dried fruit can replace glace cherries for a varied taste.
  • White Chocolate: Substitute with dark or milk chocolate for the topping or omit it entirely for a simpler version.

Additions:

  • Nuts: Add your favourite nuts like almonds, pecans, or walnuts for extra crunch and flavour.
  • Dried Fruits: Include chopped dried fruits like raisins, cranberries, or apricots for a fruity twist.
  • Candied Ginger: Finely chop candied ginger to add a spicy, sweet kick to the bars.
  • Cookies or Pretzels: Crushed cookies or pretzels can enhance texture and provide a salty contrast.

FAQ

How do I prevent the marshmallows from melting completely?

Allow the melted chocolate mixture to cool slightly before combining it with the dry ingredients to prevent complete melting of the marshmallows.

Can I use dark chocolate instead of milk chocolate?

Yes, dark chocolate can be used for a richer, less sweet flavour. Adjust sweetness based on personal preference.

Can I replace mini marshmallows with regular-sized marshmallows?

Yes, larger marshmallows can be used. Cut them into smaller pieces for easier mixing into the recipe.

Pro Tips and Guidance

  • Even Mixing: When combining the melted chocolate mixture with the dry ingredients, ensure everything is evenly coated for a well-distributed taste and texture in each bite.
  • Gentle Folding: When mixing the ingredients together, gently fold rather than vigorously stirring to prevent crushing the biscuits and marshmallows completely.
  • Cooling the Chocolate Mixture: Allow the melted chocolate mixture to cool slightly before mixing it with the dry ingredients. This prevents the marshmallows from melting and maintains their shape.
  • Pressing Firmly: Press the mixture firmly into the lined baking tin to ensure the bars hold together well after setting.
  • Clean Cuts: When slicing the set bars, use a large, sharp knife dipped in hot water and wiped dry between cuts for clean, neat slices.

Storage

  • Storage: Store the prepared rocky road bars in an airtight container at room temperature for up to one week. Keep them away from direct sunlight and heat sources to maintain their texture and flavour.
  • Freezing: Rocky road bars can be frozen for up to 2-3 months. Wrap individual bars tightly in plastic wrap or clingfilm and place them in an airtight container to prevent freezer burn. However, note that freezing might slightly alter the texture of marshmallows and biscuits upon thawing.
  • Defrosting: To defrost frozen rocky road bars, remove them from the freezer and let them thaw in the fridge for a few hours or overnight. Avoid refreezing thawed bars to maintain their quality.
