This is my Grandma’s cookie recipe she made when she worked at a bakery in Germany before WWII. She moved to the US after the war and passed this cherished recipe on to her children and grandchildren.
Add yeast, water, salt, vanilla, sugar, eggs, baking powder and butter to middle of flour.
Knead dough until all ingredients are mixed. (Alternatively, use Kitchenaid with paddle blade to combine ingredients. First cream together butter and sugar; add eggs and vanilla; whisk together dry ingredients and add to wet alternating with water).
Chill dough for ~30 minutes to make it easier to work with. Chill dough between batches.
Roll a fourth of the dough out on to the counter to 1/8″ thickiness (Make sure the dough is rolled very thin).
Cut dough into 3×3 inch squares using a pizza/dough cutter.
Put 3+ chocolate chips in the middle.
Roll dough from corner. Cookie should look like a crescent roll. Make sure to pinch the dough together so they don’t unroll when cooking.
Place on parchment-lined baking sheet. Bake in the oven for 10-12 minutes.
Let cool for ~10 minutes.
Roll in powdered sugar using a ziplock bag.
Put cookies in container/ziplock and store in the freezer for best taste.
