Brown the flour in the butter. Add milk, sugar and gum mastic. After it is cooked, add vanilla. After the mixture cools a bit, add 1 packet of powdered whipped cream and stir. Put the pudding into a large bowl. Put some of the ETİ Benim’O cookies into the pudding. Chill in the refrigerator for one day. When serving, put one Benim’O cookie on top of each bowl of pudding. If desired, rinse the bowl with water before pouring in the pudding. Then you can turn the bowl upside down and remove it before serving.
