Portuguese Biscoitos: The Traditional Recipe and How to Bake Them at Home

Biscoitos are traditional Portuguese butter cookies that originated in the Azores — most notably on the island of São Miguel — recognisable by their crisp, dry texture and their shape, either a ring or a flat disc. Originally, they were a long-lasting bake meant to keep for weeks, perfect for dipping into coffee or tea.

For centuries, Portugal was a major maritime power, and trade with its colonies brought cinnamon, vanilla, and cane sugar from the New World into local kitchens. According to culinary historians, this newfound access to once-rare ingredients transformed home baking — cookies went from being a holiday treat to an everyday pleasure enjoyed across all walks of life.

Every region keeps its own version alive:

• Azores: biscoitos — the crisp, buttery cookie rings that this whole article is about.

• Alentejo: filhós — fried anise-spiced dough, especially popular at Christmas.

• Porto: bolachas de água e sal — light, savoury crackers served at breakfast or with wine.

• Madeira: broas de mel — dense honey cookies spiced and sweetened with local honey.

When people talk about Portuguese sweets, three names usually come up: biscoitos (crisp buttery cookie rings from the Azores), pastéis de nata (flaky pastry cups filled with egg custard from Lisbon), and broas castelares (soft cookies made with sweet potato, almonds, and honey, traditionally baked for All Souls' Day). Each has its own origin story and occasion — here's a quick rundown before we get baking.

Pastéis de nata are the iconic flaky pastry cups filled with egg custard, baked at high heat until the tops develop those signature scorched spots. They first appeared before 1820 at the Jerónimos Monastery in Lisbon's Belém district — legend has it the monks used egg whites to starch their habits and turned the leftover yolks into custard. After the monasteries were dissolved in 1834, the monks sold off the recipe, and since 1837 the pastries have been baked as Pastéis de Belém.

Broas castelares are soft cookies made from sweet potato, ground corn, and almonds, sweetened with honey and lemon zest — traditionally baked around All Souls' Day and Christmas, when sweet potatoes are in season. One common mix-up to avoid: they're made with sweet potato, not pumpkin. They're named after the Castelar brothers, who first sold them at Lisbon's Confeitaria Francesa around 1860. If you're a fan of almonds in your baking, our Portuguese almond cake follows a similar spirit.

Biscoitos are the simplest of the three — dry, crisp butter cookies you can bake from what's already in your pantry, perfect for dunking in coffee or tea. They show up at family celebrations and just as easily at a quiet afternoon get-together. These are what we'll focus on now.

You can bake traditional biscoitos with just six ingredients in under an hour: cream the butter and sugar, work in the egg and flour, shape into rings or discs, and bake for 12–15 minutes at 180°C (350°F). Below you'll find exact quantities, a method with sensory cues to guide you, and the most common mistake to avoid.

• 250g all-purpose flour

• 100g granulated sugar

• 100g softened butter

• 2 eggs (medium)

• 1 teaspoon vanilla extract

• a pinch of salt

• zest of ½ lemon (optional, but highly recommended)

1. Cream the butter and sugar for 2–3 minutes until light and fluffy. The air you work in now is what gives the cookies their delicate texture.

2. Add the eggs one at a time, then stir in the vanilla and lemon zest. Adding them gradually keeps the mixture from splitting.

3. Add the flour and salt and mix just until combined. The moment the last streaks of dry flour disappear, stop — overworked dough means tough cookies.

4. Wrap the dough and chill it for 30 minutes. Chilled dough holds its shape better and won't spread while baking.

5. Shape into walnut-sized balls and flatten gently into discs (or roll the dough into thin ropes and join the ends into rings, the traditional Azorean way). Arrange on a parchment-lined baking sheet, leaving space between each one.

6. Bake for 12–15 minutes at 180°C (350°F), until the edges turn golden. Let them rest on the tray for 5 minutes before moving to a wire rack — they'll be soft straight out of the oven and only turn properly crisp once fully cooled.

Biscoitos take well to all kinds of twists. Add a teaspoon of cinnamon or a tablespoon of cocoa to the base recipe, swap the lemon zest for orange, or fold in a handful of ground almonds or chopped dark chocolate. If the almond version sounds appealing, head straight to the sister recipe below; chocolate lovers will want to check out the crisp chocolate variation.

Perfectly crisp biscoitos come down to four things: good-quality butter, brief mixing, precise oven temperature, and proper cooling. Get these right and everything else falls into place.

• Use butter, not margarine — real butter gives richer flavour and better structure. Let it soften at room temperature, but don't let it melt.

• Choose your sugar for texture — granulated white sugar gives crispness, while a pinch of brown sugar adds a caramel note and a chewier centre.

• Mix briefly — once the flour goes in, mix just until combined so the gluten doesn't develop.

• Watch your oven — 180°C (350°F) is the sweet spot. Too low and the cookies stay pale and soft; too high and the edges burn before the centre bakes through. Home ovens are commonly off by 10–20°C, so an oven thermometer is worth having.

• Cool in two stages — 5 minutes on the tray, then onto a wire rack, so the bottoms don't turn soggy from trapped steam.

• Store airtight — kept in a sealed container in a dry spot, they'll stay crisp for 7–10 days; baked cookies also freeze well for up to 3 months.

Biscoitos make a wonderful edible gift — they keep well, travel without breaking, and look instantly festive packed in a nice tin. Bake two or three flavours (classic, almond, chocolate) for a varied box that will win over even picky food lovers.

For packaging, a glass jar with an airtight lid or a tin box is your best bet — it keeps the cookies fresh and looks great too. Add a ribbon, a sheet of parchment paper between layers, and a small card with a few words about where biscoitos come from — that story turns it into a proper gift. If you're putting together a full holiday cookie box, throw in something homemade as well.
