Preheat the oven to 180 degrees Celsius (356 degrees Fahrenheit) (fan).

Split the vanilla pod and mash the seeds into some sugar.

Put flour, sugar, vanilla, almond flour, and soft butter into a mixing bowl and mix the dough well.

Gather the dough with an egg yolk.

Once the dough is gathered, it's ready to be rolled out on a floured surface. The thickness should be about 1-1.5 centimeters.

Cut the dough into stars (or the shape you desire) and place them on a baking tray lined with baking paper.

Ensure there is some space between the cookies so they don't bake together.

Bake the cookies for 6-10 minutes at 180 degrees Celsius (356 degrees Fahrenheit) (fan), and let them cool on a wire rack before packing them in an airtight container.
