Combine dry ingredients

In a bowl, mix all-purpose flour, almond flour, baking powder, Dutch speculaaskruiden, and salt.

Cream butter and sugar

In a separate bowl, cream together butter and dark brown sugar until fluffy.

Form the dough

Add the egg to the butter mixture and mix until combined, then slowly fold in the dry ingredients, alternating with milk, until a dough forms.

Refrigerate the dough

Shape the dough into a disc, wrap in plastic wrap, and refrigerate for at least 1 hour.

Do not skip the chilling step, or the cookies may spread too much.

Preheat the oven

Preheat your oven to 350°F (175°C).

Use a small cookie scoop to ensure uniform size and shape.

Prepare baking tray

Line a baking tray with parchment paper.
