Ingredients
Method
- Step 1: In a medium saucepan over medium heat, melt the butter and cook until golden brown and fragrant, stirring constantly. Once browned, transfer to a bowl and stir in espresso powder. Refrigerate for 1–2 hours, until firm.
- Step 2: In a stand mixer, beat the solidified brown butter with brown sugar and granulated sugar for 3–4 minutes, until light and fluffy.
- Step 3: Add the egg and vanilla extract, mixing until smooth and fully incorporated.
- Step 4: Add baking powder, baking soda, salt, and flour. Mix on low until just combined; do not overmix.
- Step 5: Gently fold in the Heath toffee bits until evenly distributed throughout the dough.
- Step 6: Scoop dough into large balls and refrigerate for at least 2 hours or up to 24 hours for best flavor.
- Step 7: Preheat oven to 350°F (175°C). Place dough balls on parchment-lined baking sheets, sprinkle with flaky sea salt, and bake for 11–13 minutes, until edges are golden and centers are set.
- Step 8: Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before serving.
Notes
For deeper flavor, chill the dough overnight. You can substitute the espresso powder with instant coffee granules if desired. Store cookies in an airtight container at room temperature for up to 4 days.
