You will find two different types of Lotus Biscoff spread in the supermarket, a crunchy one and a smooth one. For this rocky road recipe, I’ll be using the smooth Biscoff spread. The same I use in our other Biscoff recipes, like scrumptious Biscoff Flapjacks, Gooey Biscoff Brownies, Biscoff Banoffee Pie and these decadent Biscoff Filled Cookies.

Biscoff rocky road is unique in flavour, with caramel undertones combined with white chocolate and crunchy biscuits mixed throughout. It’s personally, one of my favourite and best rocky road recipes ever.

Equipment Needed:

  • 20cmx23cm (8x10in) Rectangular Tin: This tin will be used to shape and set the rocky road mixture. Make sure it’s the correct size for the recipe to ensure proper setting and easy removal of the traybake. You can also use a 20x20cm square tin. 
  • Mixing Bowl: A large mixing bowl will be used to combine all the ingredients and create the rocky road mixture. Choose a bowl with enough space to comfortably mix everything together.
  • Heatproof Bowl or Saucepan: You’ll need a microwave-proof bowl to melt the white chocolate and Biscoff spread. Make sure it’s microwave-safe or suitable for double boiling. If you are melting the ingredients on the stovetop, you will need a saucepan of a suitable size.
  • Spatula or Wooden Spoon: A spatula or wooden spoon will be used to stir and combine the ingredients in the mixing bowl.
  • Palette Knife or Offset Spatula (optional): A palette knife or offset spatula can be helpful for smoothing the top of the rocky road mixture once it’s in the tin.
  • Sharp Knife or Bench Scraper: A knife or bench scraper will be used to cut the set rocky road into individual portions. Choose a sharp knife or scraper for clean cuts.

Ingredients:

  • White Chocolate – The taste of white chocolate goes particularly well with the Biscoff spread so I don’t recommend substituting it for a milk or dark chocolate in this recipe. If you want a milk or dark chocolate rocky road try this Maltesers Rocky Road Recipe instead. 
  • Smooth Lotus Biscoff Spread – The Biscoff flavour is very particular and tastes similar to caramel. It cannot be substituted for other spreads. However, if you want more texture in your rocky road, you could try the crunchy version of the spread. 
  • Unsalted Butter – For most dessert and sweet recipes, I use unsalted butter. If you need to add any salt to a sweet recipe, you can be more controlled by adding the salt separately. However, in this recipe we do not need the addition of salt. 
  • Mini Marshmallows – I use the mini variety of marshmallows as you can add them whole, without needing to cut them up. It saves on time and stickiness! 
  • Lotus Biscoff Biscuits – Lots of traditional rocky road recipes in the UK contain digestive biscuits or similar. This recipe is unique in its flavour, with the addition of crunchy Biscoff biscuits broken into small pieces and mixed throughout the slices. These give the rocky road a crunchy caramel flavoured texture. 
  • White Chocolate Smarties – Multi-coloured smarties give a nice rainbow finish to your rocky road, adding colour as well as extra crunch and chocolate chunks too. If you can’t find the white chocolate variety use milk-chocolate ones instead.

Substitutions and Additions:

Wondering if you can substitute or add an ingredient? Here, I will tell you if that’s possible.

  • Nuts: Add some crunch and texture by including chopped nuts like almonds, walnuts, or pecans. Mix them in with the other ingredients for extra indulgence.
  • Dried Fruits: Enhance the sweetness and chewiness by adding dried fruits such as cranberries, raisins, or chopped dried apricots. They add a delicious contrast to the creamy white chocolate.
  • Fudge: If you want to add a twist to your rocky road, consider incorporating fudge pieces as a substitute or additional ingredient to the Smarties.
  • Sea Salt: Want to add a little enhancement to the overall flavour? Try adding a sprinkle of sea salt into the melted Biscoff spread. 

If you choose to add any of the ingredients suggested, slightly reduce the quantities of other ingredients. This ensures there is enough melted chocolate to cover everything.

Variations:

  • Biscuit/Cookie Variations: Substitute Lotus Biscoff cookies with other types of cookies or biscuits, such as digestive biscuits, shortbread, Speculoos cookies or Oreos. This variation allows you to customise the flavours to your preference.
  • Flavoured Marshmallows: Use flavoured chewy marshmallows like strawberry or vanilla for an extra burst of flavour.

Substitutions:

  • Smarties: If you can’t find Smarties, you can replace them with M&M’s or any other colourful chocolate-coated candies. The goal is to add a pop of colour and extra sweetness to the rocky road.
  • Vegan version: The good news is that you can substitute many of the ingredients in this Rocky road recipe and make it vegan. You can find, vegan marshmallows, vegan butter, vegan white chocolate and even vegan Biscoff cookie butter in most supermarkets. Leave out the Smarties or replace with some other Vegan chocolate if you wish.

Step-By-Step Guide – How To Make How To Make Lotus Biscoff Rocky Road

  • Prep the Tin: Line a 20x23cm (8x10in) baking tin with parchment paper, greased to prevent sticking.
  • Melt and Combine: In a medium saucepan, gently melt the white chocolate over a very low heat, 100g of Lotus Biscoff Smooth Spread, and unsalted butter over low heat. Stir continuously until the mixture is smooth and well blended. Allow the melted chocolate mixture to cool slightly, ensuring it is not too hot to melt the marshmallows and affect the colour of the White Chocolate Smarties. You can also use a heatproof bowl and microwave in short blasts, stirring after each one until fully melted.

  • Drizzle, Set and Slice: Heat additional Lotus Biscoff Spread in the microwave at 10-second intervals until it reaches a drizzling consistency. Be careful not to overheat. Drizzle the warmed Biscoff spread over the top of the rocky road, creating a decorative pattern. Place the tin in the fridge and let it set for at least 1 hour or until firm. Once set, remove the rocky road from the tin and carefully cut it into bars of your desired size.

Frequently Asked Questions

Can I use regular-sized marshmallows instead of mini marshmallows?

Yes, you can use regular-sized marshmallows if you prefer. Just keep in mind that you may need to cut them into smaller pieces to ensure they are evenly distributed throughout the rocky road. Larger pieces will prevent the rocky road from compacting and holding together.

Can I store the rocky road at room temperature?

Yes you can but during warmer weather it is best to store the rocky road in the fridge. When it’s hot outside, the chocolate and other ingredients may soften at room temperature, leading to a messier texture. Chilling will help the rocky road maintain its shape and stay fresh.

Can I use a different type of biscuit instead of Biscoff?

While Biscoff biscuits provide a unique flavour, you can use other biscuits such as digestive biscuits or graham crackers as a substitute. Choose a biscuit that compliments the flavours you enjoy.


Mastering This Recipe – Expert Tips

  • Line the Baking Tin: To easily remove the set rocky road from the tin, line it with greased baking paper. Lightly grease the paper with butter or a neutral-tasting oil. This will prevent sticking and make it easier to lift the bars out.
  • Firmly Press the Mixture: When spreading the mixture into the tin, be sure to press it down firmly. This helps to compact the ingredients and ensures the rocky road holds together. Avoid loose or crumbly bars by applying even pressure as you press it down.
  • Allow Chocolate to Cool: After melting the chocolate, let it cool slightly before adding the remaining ingredients. If the chocolate is too hot, it can melt the marshmallows and cause the Smarties to lose their colour. Allow it to cool for a few minutes to prevent this from happening.
  • Melting the Biscoff Spread: For easier spreading, melt the additional Biscoff spread that will be used for drizzling. Use a microwave-safe bowl and heat it in 10-second intervals, checking the consistency each time. Be cautious not to overheat it, as it can burn. Slowly and carefully heat the spread until it reaches the desired consistency.

Storage

  • Airtight Container: Store the White Chocolate Biscoff Rocky Road in an airtight container at room temperature. This will help keep it fresh and prevent it from drying out. Ensure the container is tightly sealed to maintain the texture and flavours. It will last for approximately 3 days at room temperature.
  • Refrigeration: If you live in a warm climate or during hot summer months, I would recommend to store the Rocky Road in the fridge. This will help the chocolate set and keep the ingredients firm. Place the Rocky Road in a covered container or wrap it tightly in cling film before refrigerating. It will last up to a week.
  • Freezing: You can also freeze the Biscoff Rocky Road for longer storage. Wrap individual portions or the entire tray tightly in plastic wrap or foil, then place it in a freezer-safe container or bag. It can be stored in the freezer for up to 2-3 months.
