Step 1

First, preheat oven to 375 degrees Fahrenheit. Line a baking pan with parchment paper.

Step 2

In the bowl of a stand mixer, add cold butter, white sugar and brown sugar. Beat for 2 minutes or until no clumps of butter remain.

Step 3

Then, add in egg and vanilla extract. Beat to combine.

Step 4

Add in flour, baking soda, sea salt and espresso powder. Stir until a thick dough is formed.

Step 5

Fold in chocolate chips.

Step 6

Use an ice cream scooper to scoop large balls of dough onto lined pan. Leave at least 3 inches of space between each ball of dough.

Step 7

Bake for 9 to 10 minutes or until cookies are just barely set in the middle.

Step 8

Finally, remove from oven. Allow cookies to cool on pan for 10 minutes. Then, carefully remove to a cooling rack. Sprinkle with sea salt if desired.
