Preheat the oven to 350°F and line a baking sheet with parchment paper.
In a mixing bowl, cream butter and sugars together until smooth.
Beat in the egg and vanilla extract.
In another bowl, whisk together flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients.
Stir in the chocolate chips.
Scoop dough into 12 portions and place on the baking sheet.
Bake for 8-10 minutes or until the edges are golden brown.
Let the cookies cool on a rack.
Meanwhile, melt the chocolate chips and heavy cream in a double boiler or microwave.
Stir in the instant coffee granules until dissolved.
Dip the cooled cookies into the coffee-infused chocolate, ensuring an even coating.
Let the chocolate set before serving.
