In a large mixing bowl, combine butter and powdered sugar. Beat them together on high speed using a paddle attachment for about four to five minutes until the mixture becomes light and fluffy.
Next, crack in the eggs, mixing well until they are fully incorporated. Now, pour in the milk and continue to mix.
Once your wet ingredients are ready, it’s time to add the honey and orange zest. Stir them in until everything is evenly mixed.
In a separate bowl, sift together the flour, baking powder, and vanilla extract. This ensures that your dry ingredients are evenly distributed.
Gradually add the flour mixture to the butter mixture. Mix slowly to prevent flour from flying everywhere.
Once combined, turn the dough out onto a lightly floured surface and knead it gently. Form it into a ball, then cover it with plastic wrap.
When you’re ready to bake, preheat your oven to 170°C (340°F).
Take small portions of the chilled dough, about 25 to 30 grams each, and shape them into your desired forms.
Using a brush, lightly coat each cookie with the egg yolk mixture.
Bake the cookies in your preheated oven for about 20 to 25 minutes, or until they are golden brown.
Once done, remove the cookies from the oven and allow them to cool completely on a wire rack.
