To prepare a thin and crispy chocolate chip cookies recipe, you'll need: 14 cup (60 g) chocolate chips, 1 teaspoon vanilla extract, and 1 tablespoon (25 ml) baking powder. Preheat the oven to 375?F (190?C) and grease two 9-inch (23 cm) round baking pans with non-stick cooking spray. Line the baking sheets with parchment paper and set aside. Cream the butter and sugar with an electric mixer on medium-high speed until light and fluffy, about 2 minutes. Add the egg and vanilla and beat until combined. Gradually add the flour and mix until just combined, scraping down the sides of the bowl as needed. Pour the wet ingredients into the dry ingredients, mixing just until the dough comes together. Form the mixture into balls, flattening them slightly with your hands. Flatten each ball slightly and place them on the prepared baking sheet. Bake the cookies for 12-15 minutes or until they are lightly browned. Allow to cool on wire racks before transferring to serving platters.
