Method
- Step 1: Brown the butter in a light-colored saucepan over medium heat until rich and nutty. Immediately pour into a heatproof bowl to stop cooking. Let cool slightly.
- Step 2: In a large mixing bowl, combine the slightly cooled browned butter with granulated sugar and dark brown sugar. Stir until smooth.
- Step 3: Stir in the room temperature eggs, extra egg yolk, and vanilla extract until creamy.
- Step 4: In a separate bowl, whisk together all-purpose flour, bread flour, baking soda, fine sea salt, optional espresso powder, and baking powder.
- Step 5: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Do not overmix.
- Step 6: Gently fold in the chopped semisweet chocolate and toffee bits until evenly distributed.
- Step 7: Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes.
- Step 8: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
- Step 9: Scoop about 2-tablespoon-sized balls of chilled dough onto the prepared baking sheets, leaving 2 inches between them.
- Step 10: Bake for 10–12 minutes, until the edges are golden brown and centers are set but soft.
- Step 11: Immediately sprinkle cookies with flaky sea salt. Let rest on the baking sheet for a couple of minutes, then transfer to a wire rack to cool completely.
Notes
For extra crunch, add ½ cup of chopped toasted pecans or walnuts. Swap semisweet chocolate for milk or dark chocolate. If you can't find toffee bits, chop Heath or Skor bars.
