In the bowl of a stand mixer (or using a hand mixer), cream together butter, brown sugar, and white sugar on medium speed until light and fluffy (2 to 3 minutes).
¾ cup packed brown sugar, ¾ cup unsalted butter, softened, ½ cup granulated sugar
With the mixer on low, add egg and vanilla. Return mixer to medium and mix until incorporated. Scrape sides if needed.
1 large egg, 1 teaspoon vanilla bean paste
With the mixer on low, add dry ingredient mixture gradually until dough forms. Stir in chocolate chips by hand. Refrigerate dough for at least 30 minutes.
1 ½ cups semi-sweet chocolate chips
When you're ready to bake the cookies, preheat oven to 350ºF, and line baking sheets with parchment paper or Silpat, and set aside.
Form balls from generous 1 tablespoon of dough. I use my small scoop. Arrange balls on prepared baking sheet with space between to allow for spreading (see note).
Bake cookies for 9 to 11 minutes or until edges are just barely golden. Remove from the oven and let the cookies cool for about five minutes on baking sheet before transferring to a wire rack to cool completely.

Notes
Bakery-style cookies: If desired, place 2 to 3 chocolate chips on top of each ball of dough before baking for a pretty appearance.
Storage: Cool the cookies completely before storing in an airtight container. They'll keep for at least a week at room temperature, or can be frozen for up to 3 months.
Variations: You can substitute 1 cup of whole wheat flour for 1 cup of all-purpose flour. Feel free to use different varieties of baking chips, such as Reese's Pieces, milk chocolate chips, or M&Ms.
