Iloilo Biscocho: Twice-Baked Bread with a Crisp Butter-Sugar Finish

Biscocho is a familiar Iloilo pasalubong: bread sliced, dried and given a sweet buttery crisp finish. The Philippine Information Agency’s 2025 account of an Ilonggo food showcase identifies biscocho among the region’s featured baked products, while PagkainPinoy provides a home recipe for biscocho de Iloilo. In the kitchen the challenge is moisture. Too much butter before the bread dries produces greasy centres; too hot an oven burns the sugar while the inside stays soft. The answer is a deliberate two-stage bake with an honest cool-down test. Source 1 Source 2

What to prepare and decide

The Biscocho de Iloilo recipe uses a sound day-old loaf or rolls sliced about 1 cm thick, ½ cup softened butter, ½ cup sugar, an optional 2 tbsp milk powder and ½ tsp vanilla, plus a pinch of salt. The loaf’s actual size determines whether it gives the recipe’s 24–30 pieces. Use clean trays, a rack and a 150°C oven setting as the source’s starting point; check your appliance’s fan-conversion guidance. Source 1

A method you can repeat

1. Choose bread of similar thickness and composition. Cut as evenly as possible so thin ends do not burn while thick centres remain soft. A serrated knife gives clean slices without compressing a delicate loaf. Do not use bread with any visible mould; baking is not a safe salvage method.
2. Arrange slices in a single layer and begin at the recipe’s 150°C setting for 10–12 minutes, turning once. Aim for a dry pale surface rather than dark browning. Thickness and the oven change the actual time.
3. Let one trial slice cool briefly. Bread often feels more tender while hot, so a quick cool sample gives a better read of whether the inner crumb has dried. Return the batch for a little more gentle drying if it remains clearly moist.
4. Mix the softened butter, sugar, vanilla, salt and optional milk powder into a smooth spread. Apply a thin, even layer to one side rather than mounding it at the centre. Excess butter can soak the bread and delay crispness; a patchy coating makes some pieces oversweet and others bland.
5. Bake the thinly buttered slices for another 15–20 minutes at the same source setting, checking and rotating trays as needed until the edges are light gold. If the topping colours before the middle dries, lower the heat rather than letting the sugar scorch.
6. If the cooled test slice still has a moist centre, the recipe suggests another 5–10 minutes at 120°C. Cool the whole batch on a rack before packing so trapped steam does not soften it. Count unbroken crisp slices only after this check.

Why these choices matter

Twice-baking separates structural drying from sweet browning. The first stage removes moisture without burning; the second provides the butter-sugar surface. When both are attempted at full heat at once, the sugar may turn dark before the inner bread finishes drying. A cool test slice is a practical quality control that travels well from a home tray to a small bakery batch.

Serving, variations and real-world trade-offs

Serve as a dry merienda with coffee or tea. If pricing a pasalubong pack, count finished unbroken slices, wrapping materials and fuel rather than dividing costs by the initial loaf’s nominal slice count. A broken slice can still be eaten at home; it should not silently count as a saleable gift biscuit. The fan-versus-conventional oven guide helps avoid applying a temperature conversion twice.

Food safety and handling

Use sound bread and clean bakery tools. Butter and any milk-powder ingredients carry dairy allergens. Do not claim a fixed long shelf life for a homemade pack without a validated product, packaging and moisture-control process. Follow safe storage for the ingredients used. Source 4
