After thawing the frozen kunafa dough, cut into about 1 cm in length.
Add vanilla extract and the coffee mixture, then mix again.
Scrape down the sides and the bottom of the bowl.
Bake for 11-14 minutes, or until a toothpick inserted in the center of the brownie comes out clean.
Cool for 5-10 minutes. Then, use the bottom of a small glass to press into the center of each brownie, creating a well. Press further with your fingers if needed.
Optional: Top with more chopped pistachios and a slice of chocolate for extra flavor and decoration.
