Method
Make the cookie dough
- Heat the oven to 350°F and line two 18x13-inch rimmed baking sheets with parchment paper.
- Whisk the flour and baking soda together in a medium bowl.
- Beat the butter, brown sugar, and granulated sugar in a large bowl on medium speed until light and fluffy, about 2 minutes.
- Beat in the eggs one at a time.
- Beat in the vanilla extract.
- Mix in the flour mixture on low speed just until no dry streaks remain.
- Fold in the butterscotch chips and chocolate chips.
- Cover the dough and refrigerate for 30 minutes.
Bake and finish the cookies
- Portion the dough into 24 balls, about 3 tablespoons each.
- Arrange 12 on each baking sheet, leaving at least 2 1/2 inches between them.
- Bake both sheets for 11–13 minutes, switching their positions and rotating them front to back halfway through, until the edges are golden and the centers still look soft.
- Sprinkle the warm cookies with the flaky sea salt.
- Let them cool on the baking sheets for 5 minutes.
- Transfer them to a wire rack to cool.
Notes
For soft centers, take the cookies out when the edges are golden and the centers still look soft. Store in an airtight container at room temperature for up to 4 days; freeze baked cookies for up to 3 months. For a dairy-free variation, use dairy-free butter and chocolate and butterscotch chips.
