Ingredients
 

Main Ingredients

  • 0.9 cup unsalted butter, softened
  • 0.5 cup granulated sugar
  • 0.28 cup light brown sugar, packed
  • 2 tsp pure vanilla extract
  • 0.5 tsp fine sea salt
  • 0.5 tsp baking powder
  • 2 tbsp cornstarch
  • 2.1 cup all-purpose flour
  • 1.1 cup toffee bits (chopped toffee candy)
  • 0.25 tsp flaky sea salt optional, for finishing

Instructions

Preparation Steps

  • Beat butter with both sugars until pale and fluffy, 2–3 minutes.
  • Mix in vanilla and fine salt until smooth.
  • Whisk flour, cornstarch, and baking powder in a separate bowl.
  • Add dry ingredients to the butter mixture in two additions; mix just until a soft dough forms.
  • Fold in toffee bits until evenly distributed.
  • Divide dough in half; shape each into a 1¾-inch-thick log.
  • Wrap logs tightly and chill until very firm, 1–2 hours.
  • Heat oven to 350°F. Line two baking sheets with parchment.
  • Slice chilled logs into ¼-inch rounds and set 2 inches apart on sheets.
  • Bake 10–12 minutes, until edges turn light golden. Rotate pans halfway through.
  • Cool 5 minutes on the sheet, then transfer to a rack. Sprinkle flaky salt if using.

Notes

Variation: Swap 1/2 tsp almond extract for part of the vanilla, or roll the logs in coarse sugar before slicing for sparkle. Storage: Refrigerate dough up to 3 days or freeze logs up to 2 months; slice from frozen and add 1–2 minutes to bake time.
