Preferably take a wide and flat tray with shortest height.
Grease it with oil.
Sprinkle some wheat flour all over the tray.
Spread the flour inside the tray.
Turn down the tray so that excess flour is dusted out. Keep aside.
Take a bowl and place a sieve over it.
Add 1+1/4 cup flour, 1/4 cup milk powder, 1/2 cup powdered sugar, pinch of salt, 1/4 tsp cardamom powder, 1 tsp baking powder and 1/2 tsp baking soda.
Sift the ingredients in the bowl.
Add 2 tbsp semolina and mix.
Add 2 tbsp oil and mix.
Now slowly start adding milk and keep mixing the batter. For a smooth consistency of batter, about 1 cup + 2 tbsp of milk was used.
Transfer this batter into greased tray and spread evenly.
Place the tray in pre-heated oven and bake for 30 minutes @180 degree C in the middle rack with both the rods on.
Insert a toothpick and if it comes out clean, means bread is properly baked.
Bring the tray out and let bread cool down completely.
Take the bread out of the tray and place on chopping board.
Invert the bread from the tray and place bread on cooling rack for cooling completely.
Now it's a time to cutting. For proper piece of rusk, you can use scale to cut bread into pieces. The bread is cut into the shape of rusk.
Arrange these pieces on a baking tray.
Bake in a pre-heated y @150°C for 30 minutes initially.
Open the oven, turn the sides of the bread sticks.
Further bake @150°C for 30 minutes more or until bread sticks turn crisp.
As we like slightly dark brown rusk, so shifted the baking tray on top rack of the oven and baked just for 1 minute at @230°C with only top rod on. So can skip this part if don't like the deep colour of rusks.
Bring the tray out and arrange all rusks on cooling rack for complete cooling.
Whole wheat rusks are ready.
