Browned Butter Toffee Chocolate Chip Cookies

Step 1

In a medium stainless sauté pan set over medium heat, melt the butter. Swirling the pan occasionally, continue to cook the butter. It should become foamy with audible cracking and popping noises. Once the crackling becomes quieter, continue to swirl the pan or stir until the butter develops a nutty aroma and brown bits start to form at the bottom. Once the bits are amber in color, remove from heat and pour into a mixing bowl.

Step 2

Add the granulated sugar and brown sugar to the hot butter, stirring to combine. Set aside to cool to room temperature.

Step 3

In a medium bowl combine the flours, baking soda, espresso powder, baking powder, and salt.

Step 4

To the cooled butter mixture, whisk in the eggs, yolk, and vanilla until combined. Gradually stir in the flour mixture with a rubber spatula. Stir in the chocolate chunks and toffee bits. Wrap dough in plastic wrap and refrigerate for at least 24 hours but no more than 72 hours.

Step 5

Let dough sit at room temperature just until it is soft enough to scoop, about 1 hour.

Step 6

Preheat the oven to 350ºF. Line baking sheets with parchment paper.

Step 7

Divide the dough into 3-tablespoon sized balls and drop onto prepared baking sheets. Dough may be slightly challenging to scoop.

Step 8

At this point you can portion the dough, place it on a baking sheet and freeze until solid. Remove frozen balls of dough to an airtight container and store for up to 6 weeks.

Step 9

Bake for 12 to 14 minutes, or until golden brown. Remove from oven and sprinkle flaky sea salt on top of the cookies, if desired. Let cookies cool for 2 minutes before removing to wire racks to cool completely.

Step 10

Store in an airtight container at room temperature for up to 3 days.
