Portion cookies onto baking sheets: Using a tablespoon measure or a small ice-cream scoop, drop heaping portions of dough about 2 inches apart onto prepared baking sheets.
Bake cookies: Bake until cookies are golden around the edges, but still soft in the center, 8 to 10 minutes. Remove from oven, and let cool on baking sheet 1 to 2 minutes.
Cool and store: Transfer cookies to a wire rack and let cool completely. Store cookies in an airtight container at room temperature up to 1 week.
