Step 1

Preheat oven to 350°F. Line two baking sheets with a baking mat or parchment paper and set aside.

Step 2

Melt 1 stick of the butter in a pan over medium-heat. Cook for about 3-5 minutes, swirling the pan every so often. Allow the butter to brown (when it turns an amber golden color and has a nutty aroma, it’s done). Remove from the heat and then pour into a bowl and chill for 5 minutes.

Step 3

In a large bowl, combine the remaining 1/2 cup softened butter, brown sugar and white sugar. Mix for 1 minute, until smooth and creamy. Then add in the melted brown butter and stir until combined. Mix in the eggs and vanilla.

Step 4

Then add the flour, salt and baking soda. Mix until well combined. Stir in the chocolate chips and toffee bits. Cover and refrigerate until ready to bake.

Step 5

Scoop cookie dough onto the prepared pan, about 2 inches apart. Press extra toffee bits or chocolate chips on top if desired. Bake for 7-9 minutes, or just until the edges are golden brown, while the center is still slightly doughy. For a crispier cookie bake the full 9 minutes.

Step 6

Remove from oven and allow the cookies to cool for a few minutes on the pan. Sprinkle with flaked salt if desired. Then move to a cooling rack.
