1/2cup+ 2 tablespoon of granulated sugar(125 grams)
1 3/4cups+ 2-3 tablespoons of all purpose flour(250 grams)
1 teaspoonbaking powder
1/2cupmini chocolate chips(100 grams)
Pre-heat oven to 350F (180C). Line a large cookie sheet with parchment paper.
In a large bowl whisk together the eggs, sugar and vanilla, then add the salt, flour and baking powder, mix together with a fork or with the flat beater, just until almost combined then add the chocolate chips. Mix to almost combined.
Move to a lightly flour flat surface and form into two logs about 12 inches (31 cm). If the dough is a little sticky then add a little more flour to the surface. Place the logs on the prepared cookie sheet, brush lightly with beaten egg yolk and bake 15-20 minutes, the dough should still be soft. Remove, let sit 2-3 minutes then slice (about 1/4 " or less if you wish) on the diagonal and bake for another 5-10 minutes or until dried. Let cool completely before serving. Enjoy!
