Preheat the oven to 350°F.
In a bowl, whisk together the flour, baking soda, instant coffee granules, and salt.
In a separate bowl, cream together the butter, brown sugar, and granulated sugar until smooth.
Add the egg and vanilla flavoring and mix well.
Gradually add the dry ingredients to the wet ingredients and mix until combined.
Fold in the chocolate chips or chunks.
Scoop the dough onto a lined baking sheet.
Place the pan with the scooped batter into the fridge for 5–7 minutes to cool slightly. This helps the cookies retain their shape and not flatten out when baking.
Bake for 13 minutes.
Remove from the oven and allow the cookies to cool. Enjoy warm!
