These chocolate shortbread cookies are crumbly, buttery and practically melt in your mouth. They aren't overly sweet either, which is how I like my shortbread cookies.
In a stand mixer, beat butter and confectioners’ sugar together on medium speed for about 3 minutes, until the mixture is very smooth. Beat in vanilla, then reduce mixer speed to low and add flour and cocoa powder, mixing only until it disappears into the dough.
Gather dough and place in between two sheets of parchment paper. Roll the dough into a rectangle shape that’s 1/4 inch thick. Refrigerate the dough for at least 2 hours.
Once the dough is firm, preheat the oven to 325°F. Cut the dough into 1 1/2-inch rectangles. Bake the cookies for 18 to 20 minutes.
