- Arrange 12 portions at least 2 inches apart on the baking sheet and keep the rest chilled.
- Bake the first batch for 10–12 minutes, until the edges are golden and the centers still look slightly underdone.
- Immediately sprinkle the cookies with flaky sea salt.
- Let the cookies rest on the sheet for 5 minutes.
- Transfer the cookies to a wire rack.

Notes
For chewy centers, take the cookies out when the edges are golden and the centers still look slightly underdone. Store in an airtight container at room temperature for up to 5 days; baked cookies can be frozen for up to 2 months. For a dairy-free variation, use dairy-free butter and dairy-free caramel and toffee bits.
