Place the sesame seeds, single layer, in a large cast iron frying pan, and toast to a nice golden color.
Remove and set in a shallow bowl.
Place the flour, sugar, baking powder and salt in a large bowl.
Beat the eggs in a smaller bowl and stir in the melted butter and vanilla and add to the flour mixture.
Stir together until well incorporated.
On a clean, lightly floured surface, knead the dough a few times until smooth. Divide dough into sections. Taking one piece, roll into a long rope, about ½ inch thickness. Cut into 2-inch logs.
Fill a small bowl with cool water, dip each log in the water and then roll logs the toasted sesame seeds.
Place on a non-stick baking pan or a pan lined with parchment.
Bake 25 – 30 minutes or until a beautiful golden color is achieved.
