Preheat your oven to 350 degrees. Line 2 Baking sheets with parchment paper.
In a mixing bowl, whisk together the flour and baking powder. Set aside.
In another mixing bowl combine the eggs, extract, sugar, milk, oil and zest. Mix with a fork until smooth.
Add in the dry ingredients and mix with your hands until a dough that doesn’t stick to your hands forms. If the dough feels sticky, add 1 tablespoon of flour at a time until the desired consistency is reached.
Working with a tablespoon of dough at a time, roll the dough into a ball and then roll it into a log about 1 1/2 inches thick.
Roll the logs in granulated sugar and place the cookies 2 inches apart on the baking sheet.
Using the palm of your hands, gently press down and flatten each cookie into an oval shape.
Dust each cookie generously with confectioners sugar and bake for 25-30 minutes or until the bottoms of the cookies just begin to brown.
