Preheat oven to 350 degrees F (175 degrees C). Dust 2 baking sheets with flour.
Combine brown sugar and butter together in a bowl; beat with an electric mixer until light and fluffy. Beat in egg, cinnamon, baking powder, cloves, and nutmeg. Mix in flour, 1 cup at a time, until dough comes together.
Shape dough into cookies by hand or using cookie cutters. Arrange on the prepared baking sheet.
Bake in the preheated oven until firm but not hard, about 10 minutes. Transfer to a wire rack to cool.
I always flour my baking sheets rather than greasing them when baking; I personally think it has a much better quality. If you do not want to flour the baking sheet, you must grease it.
If you really want to have a lot of fun, purchase a speculaas plank, which is a wooden mold created especially for these cookies. Flour the mold and gently press the dough in. Flip the mold over the baking sheet and peel the cookie out. I am constantly praised and asked about my gorgeous, delicious cookies and frequently use them as Christmas gifts and treats when I've used the mold.
