Cream the butter and confectioner’s sugar on medium speed until smooth, about 2-3 minutes.
Add the eggs one at a time mixing until incorporated. Mix in vanilla extract and salt.
Next add 120 grams (1 cup) of flour and 1 teaspoon of baking powder at a time and beat with the mixer on low until just incorporated. Continue adding 120 grams (1 cup) of flour and one teaspoon of baking powder until you have added 5 of each.
Whisk together the remaining cup of flour and teaspoon of baking powder in a separate bowl.
Sprinkle half of the remaining flour onto a wooden board or counter top, remove the dough from the bowl and place it on top of the flour. The dough will be sticky. Sprinkle a bit of the flour on top of the dough. Gently incorporate, by kneading, as much flour as you need so that the dough is smooth but is still the slightest bit sticky.
Shape the dough into cookies by taking a 20 gram ball of dough and rolling it into a rope 4” long and creating a knot. (see video above)
Bake for 15 minutes or until light golden brown.
