Beat together butter and sugars in a large bowl with an electric mixer at high speed until pale and fluffy, 2 to 3 minutes. Lightly beat 1 egg with a fork in a small bowl and add 1 3/4 tablespoons of it plus remaining whole egg to butter mixture, beating with mixer until creamy. Beat in vanilla. Reduce speed to low and mix in flour mixture until just blended, then stir in chips.
