Ingredient notes

Ingredients for chocolate tiffin.

Digestive biscuits: Place in a plastic bag and crush with a rolling pin, leaving some larger pieces for texture. Swap for rich tea biscuits, graham crackers (US) or ginger biscuits.

Butter: Unsalted is preferred.

Golden syrup: Use clear runny honey if you can’t get golden syrup.

Chocolate: Use a mix of dark and milk chocolate for the base, and milk chocolate for the topping.

Cocoa powder: Adds an extra chocolate boost to the base.

How to make tiffin

The recipe card with ingredient quantities and the full method is below.

One: Line a 20cm (8″) square tin with non-stick baking paper or clingfilm.

Two: Place the butter, golden syrup, and broken pieces of dark and milk chocolate in a large microwave-safe bowl. Microwave in 30-second bursts, stirring between bursts, until fully melted and combined.

Three: Fold in the crushed digestive biscuits and cocoa powder until the biscuits are fully coated in chocolate.

Four: Press the mixture firmly into the lined tin — use the back of a heavy spoon to compact the mixture tightly.

Five: For the topping, melt milk chocolate with a few drops of vegetable oil in the microwave in short bursts to keep it smooth. Spread the melted chocolate over the base, then refrigerate for at least 2 hours, preferably overnight.

Six: Remove from the fridge 10–15 minutes before cutting to avoid the topping cracking when sliced.

Top tips

  • Use good quality chocolate — it makes a big difference.
  • Add a few drops of vegetable or coconut oil to the melted milk chocolate topping to reduce cracking.
  • Let the tiffin sit at room temperature for 10–15 minutes before slicing for cleaner cuts.
  • Use a long, sharp knife and wipe it between cuts for neat bars.
  • For a more adult flavour, use all dark chocolate in the base.

Variations

  • Add 75g chopped walnuts or pecans for extra crunch.
  • Stir a few tablespoons of smooth peanut butter into the melted chocolate for a peanut butter twist.
  • Fold in 100g dried fruit like raisins, chopped apricots, glace cherries or cranberries.
  • Swap the biscuits for ginger biscuits, shortbread, Oreos, hobnobs or jammie dodgers.
  • Stir in crushed honeycomb, Smarties, mini eggs, chopped chocolate bars or other sweets.
  • Add peppermint extract and top with crushed candy canes for a festive version.
  • Use white chocolate in the base and add dried cranberries or pistachios for colour and contrast.
  • Add a splash of Baileys for a boozy chocolate tiffin.

Storage

Make-ahead: Prepare up to 3 days in advance.

Store: Keep tiffin bars in an airtight container in a cool, dry place. In hot weather, refrigerate to prevent melting. They’ll keep up to 5 days.

Freeze: Tiffin freezes well — place cut bars in a freezer-safe container for up to 3 months, or wrap the whole slab in two layers of foil and freeze as one piece.
