Afghan Biscuits
Classic New Zealand chocolate cornflake biscuits topped with chocolate icing and a walnut half.

Preparation: 25 min · Cooking: 15 min · Total: 1 hr 35 min · 24 servings
Ingredients
- 50 g plain cornflakes, lightly crushed — Leave visible flakes.
- 25 g unsweetened cocoa powder — Use 20 g in the dough and 5 g in the icing.
- 200 g unsalted butter, softened — Use 180 g in the dough and reserve 20 g for the icing.
- 160 g plain wheat flour
- 24 pc walnut halves — One half per biscuit.
- 150 g icing sugar
- 115 g caster sugar
- 5 ml vanilla extract (optional)
- 30 ml hot water — Add only as needed for the icing.
Instructions
Prepare the trays and ingredients
Heat the oven to 180°C conventional (160°C fan) with a rack in the middle. Line two trays. Lightly crush the cornflakes with your hands; leave visible flakes. Reserve 20 g of the butter for the icing and keep the walnut halves aside for the finish.
Cream butter and sugar
Beat 180 g softened butter with the sugar and vanilla for 2–3 minutes until smooth and a little paler. Do not melt the butter; a soft, creamy base keeps the biscuits rich rather than cakey.
Mix the cocoa-cornflake dough
Whisk flour with 20 g cocoa powder, then mix into the butter base just until no dry flour remains. Fold in the crushed cornflakes with broad strokes, keeping their crunch. The dough will be thick and slightly crumbly but should hold when pressed.

Portion the biscuits
Scoop 24 level tablespoons of dough, roll only enough to bring each portion together, and place 5 cm apart. Flatten each to a rough 5 cm round about 1 cm thick; an uneven surface is characteristic and holds the icing well.
Chill the shaped dough
Cover the trays and refrigerate for the preserved 30-minute timer. Chilling firms the buttery dough and helps the biscuits keep a thick, craggy shape. If the dough becomes too firm, leave it for 5 minutes at room temperature before baking.

Bake until set
Bake one tray at a time for 12–15 minutes. The biscuits are ready when the edges are set and the tops lose their wet shine; do not wait for them to become hard in the oven because they firm while cooling.
Edges are set, the top is matte, and the biscuit is still tender while warm; it firms as it cools.
Cool before icing
Leave the biscuits on the tray for the preserved 10-minute timer, then transfer carefully to a wire rack. They must be fully cool before icing; warm biscuits melt the topping and break easily.

Ice, finish, and store
Sift the icing sugar with the remaining 5 g cocoa. Rub in the reserved 20 g butter, then add hot water a teaspoon at a time until the icing is thick and spreadable, not runny. Spread about 1 teaspoon on each cool biscuit and press one walnut half on top. Let the icing set for the preserved 25-minute timer before packing or serving.

Tips
- Keep the cornflakes in visible pieces; fine crumbs lose the biscuit’s signature crunch.
Common mistakes
- Overmixing crushes the cornflakes and makes dense biscuits.
- Icing while warm makes the topping slide off.
Substitutions
- Use pecan halves in place of walnuts if needed; omit the nut only for allergy requirements.
Storage
Store completely cooled, iced biscuits airtight at cool room temperature for up to 4 days, with baking paper between layers.
Reheating
Serve at room temperature; these biscuits do not need reheating.
