Combine all the ingredients in a large bowl and mix well until fully blended.

Grease the baking pan with 1 tablespoon butter and sprinkle with some fine breadcrumbs.

Pour the basbousa mixture into the pan and bake at 350°F (180°C) for 30 minutes, or until golden and cooked through.

Pour the hot syrup over the basbousa as soon as it comes out of the oven. Return it to the oven for another 4 minutes with the door slightly open. You can cover it after removing from the oven. Enjoy!
