Preheat the oven to 180º C\356º F. Grease a large rectangular pan with oil. In a medium sized bowl, mix the condensed milk, semolina, butter, coconut and baking powder. Pour in the pan and spread it with a spoon. Garnish with nuts and bake it for 30 minutes/ until nice and golden in color.(Keep checking after 20 minutes thru the glass) Drizzle with sugar syrup (very less) and set it aside to cool. (Only if u need- but it tastes better with sugar syrup) Cut into squares and serve.
