To prepare a very rich very thin chocolate lace cookies cookies recipe, first you need to prepare your ingredients. First, you'll need your chocolate chips. You can buy them at most grocery stores, or you can make your own at home. Then, add your flour, baking powder, salt, and cocoa powder to your mixing bowl and mix until the ingredients are well combined. Next, pour your wet ingredients into your dry ingredients and stir until they're evenly coated. Finally, knead your dough until it's smooth and elastic. Roll the dough into balls and place them on ungreased cookie sheet. Bake the cookies for 10 to 12 minutes or until golden brown. Allow to cool on the baking sheet for 5 to 10 minutes.
