Place the Lotus Biscoff biscuits and digestives into a plastic freezer bag, seal it, and crush them into small pieces using a rolling pin. Avoid turning them into dust. Transfer the crushed biscuits into a bowl.
200 g Lotus Biscoff Biscuits, 50 g Digestive Biscuits
In a microwave-safe bowl, melt the white chocolate and butter in 30-second bursts, stirring between each interval. In a separate bowl, melt the Biscoff spread for 30 seconds. Do not melt the white chocolate and Biscoff spread together to avoid the mixture seizing and becoming grainy. Combine the melted white chocolate mixture and Biscoff spread with the crushed biscuits and golden syrup, and mix thoroughly.
200 g White Chocolate, 3 tablespoon Golden Syrup, 175 g Biscoff Spread, 75 g Butter
Press the mixture firmly into a 20 cm square baking tin lined with cling film, using the back of a spoon to compact it evenly.
Melt the additional Biscoff spread and drizzle it over the tiffin. Sprinkle with 1 crushed Lotus Biscoff biscuit. Place the tin in the fridge for 2 hours to set before cutting into bars.
