These cookies are irresistibly soft and buttery, bursting with a bold chocolate coffee flavor. The walnuts add a wonderful crunch and texture that perfectly complements the richness of these cookies.
Cream the softened butter, sugar, and vanilla together until light and fluffy.
In a separate bowl, whisk together the flour, cocoa powder, instant coffee, and salt. Gradually add this mixture to the creamed butter mixture, mixing until just combined.
Fold in the finely chopped walnuts, ensuring they’re evenly distributed.
Cover the dough and refrigerate for at least an hour or overnight. Chilling helps the dough firm up and prevents excessive spreading during baking.
Preheat your oven to 350°F (175°C).
Roll the chilled dough into 1-inch balls and place them on an ungreased baking sheet, leaving space between each.
Bake for 12–15 minutes or until the cookies are set. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.
While still warm (but not hot), dust the cookies generously with powdered sugar.
