Speculoos (Biscoff-Style) Cookies

Before you start

Speculoos, or speculaas, are spiced shortcrust cookies from Belgium and the Netherlands, traditionally pressed into carved wooden molds. The Belgian style sold as Biscoff is plainer in shape and leans more on caramelized brown sugar than on spice, with a crisp, snappy texture that is good on its own and better dunked in coffee.

Three choices shape the result. Dark brown sugar plus a little dark syrup gives the deep caramel taste. A long rest lets the flour fully absorb moisture and the spices bloom; you can bake after 2 hours, but an overnight rest gives a more even, crunchier cookie. Finally, roll the dough thin and bake it until it is deeply browned at the edges and dry throughout, since speculoos should not bend at all.

Ingredients

• 250 g (2 cups, spooned and leveled) all-purpose flour
• 2½ tsp ground cinnamon
• ½ tsp ground ginger
• ¼ tsp ground nutmeg
• ¼ tsp ground cloves
• ¼ tsp ground cardamom
• ⅛ tsp finely ground white pepper
• ½ tsp baking soda
• ¼ tsp fine salt
• 115 g (½ cup) unsalted butter — softened
• 150 g (⅔ cup packed) dark brown sugar
• 2 tbsp (40 g) dark candi syrup, golden syrup or mild molasses
• 1 tbsp milk

Method

1. Whisk the flour, all the spices, baking soda and salt in a bowl until the spices are evenly distributed.
2. Beat the butter, brown sugar and syrup on medium speed for 2 minutes, until smooth. Beat in the milk.
3. Add the dry ingredients on low speed and mix until the dough clumps together. It will look a little dry at first; press it into a ball by hand.
4. Divide the dough in half and roll each half between two sheets of parchment to 3 mm (⅛ in) thick. Refrigerate the sheets for at least 2 hours, or overnight.
5. Heat the oven to 175°C (350°F) and line the baking sheets with parchment. Cut the cold dough into 7 x 4 cm (2¾ x 1½ in) rectangles with a pizza wheel and a ruler, or use a fluted cutter. Space them 2 cm (¾ in) apart. Re-roll and chill scraps.
6. Press a pattern into each cookie with a stamp or the tines of a fork if you like.
7. Bake one sheet at a time for 12 to 15 minutes, until deep golden brown all over and slightly darker at the edges. Thin edges brown fastest, so rotate the pan halfway through.
8. Cool the cookies on the sheet for 5 minutes, then move them to a rack. They crisp fully as they cool; any that bend once cold can go back in the oven for 2 minutes.

Tips for success

• Make the spice mix in a larger batch and store it in a jar; it keeps for months and makes the next round quicker.
• Even thickness matters more than the exact shape. Use rolling pin guide rings or two 3 mm strips of wood as rails.
• If you own a carved speculaas mold, dust it with rice flour, press the dough in firmly and tap it out onto the sheet.

Substitutions

Dark brown sugar

Light brown sugar works but gives a paler cookie with less caramel depth. Add an extra teaspoon of syrup to compensate.

Candi syrup

Golden syrup is the closest common swap. Molasses makes a darker, more bitter cookie, so use only 1 tablespoon with 1 tablespoon of honey.

All-purpose flour

A gluten-free 1-to-1 blend works well in rolled spice cookies. The dough is more fragile, so keep it cold while cutting.

Variations

Speculoos cookie butter

Grind 200 g baked cookies to fine crumbs in a food processor, then blend in 80 ml evaporated milk, 2 tablespoons neutral oil and 1 tablespoon brown sugar until smooth. Refrigerate and use within 1 week.

Almond speculaas

Press sliced almonds onto the back of each cookie before baking, as in the Dutch style.

Troubleshooting

Cookies are chewy instead of crisp

They were underbaked or rolled too thick. Bake until evenly deep brown and keep the dough at 3 mm; re-crisp them at 150°C (300°F) for a few minutes.

Edges burn before the centers brown

The dough was uneven or the pan is dark. Roll evenly between guides and use a light-colored sheet, rotating it halfway.

Spice flavor is flat

The spices were old or the dough did not rest. Use fresh ground spices and rest the dough overnight before baking.

Storage

Store the cookies in an airtight tin at room temperature for up to 3 weeks. The dough keeps wrapped in the refrigerator for up to 3 days or in the freezer for 2 months.

Safety notes

Contains wheat and milk. Even without eggs, raw dough made with untreated flour should not be eaten.
