These cinnamon speculoos cookies (also called Biscoff or speculas cookies) are deliciously crispy and fragrant. Their distinctive spicy aroma comes from the addition of a LOT of cinnamon and the caramelizing of the brown sugar. Yummy.
Roll out the dough to 3 mm (0.1 inch) thickness and cut out shapes with a cookie cutter. Leave to dry out at room temperature for 2 hours before baking.
Preheat the oven to 180°C (355F). Bake in the oven for 10 to 15 minutes.
