Step 1

Preheat oven to 350 degrees. Line baking sheets with parchment paper or nonstick baking mats; set aside.

Step 2

In the bowl of an electric mixer fitted with the paddle attachment, cream together butter and sugars. Add eggs, one at a time, mixing well after each addition. Reduce speed to low and add both flours, baking powder, baking soda, vanilla, and chocolate; mix until well combined.

Step 3

Using a 4-ounce scoop for larger cookies or a 1-ounce scoop for smaller cookies, scoop cookie dough onto prepared baking sheets, about 2 inches apart. Bake until lightly browned, but still soft, about 20 minutes for larger cookies and about 15 minutes for smaller cookies. Cool slightly on baking sheets before transferring to a wire rack to cool completely.
