Method
Preparation
- In a stand mixer, combine softened butter, shortening, and packed brown sugar. Mix until sandy and lump-free.
- Add eggs one at a time, beating well after each addition, and stir in vanilla.
- Whisk flour, baking soda, cream of tartar, and salt separately.
- With mixer on low, gradually add dry ingredients to wet mixture, mixing until just combined.
- Fold in toffee bits and chopped pecans by hand.
- Shape dough into two 10-inch logs and wrap tightly in plastic wrap.
- Freeze the wrapped logs for at least 4 hours or until firm.
Baking
- Preheat the oven to 375°F (190°C).
- Unwrap frozen logs and slice into 1/2-inch rounds. Place slices 2 inches apart on baking sheets.
- Bake for 9–11 minutes until edges are lightly browned and centers are set.
- Cool on pans until firm, then transfer to a wire rack to finish cooling.
Notes
For a nut-free version, omit pecans and add an extra 1–2 oz of toffee bits or 1/2 cup chocolate chips. Store cookies in an airtight container for up to 4 days.
