Take 6 pieces of bread.

Remove their edges with pizza cutter/knife.

Again divide them in 2 equal parts with knife/pizza cutter. Keep aside. Now I have 12 pieces out of 6 bread pieces. However it will depend upon the size of bread you choose.

Take the white chocolate slab and grate some of it in one plate and chop some on the other and keep aside.

Take a bowl, add milk power, powdered sugar and cocoa powder.

Make a paste with water which should neither be too thick nor too runny. Be careful while adding water. Add water, spoon by spoon, stirring continuously.

Take the melted chocolate in another bowl and add vanilla essence & milk to make it little creamy.

At last, take some milk at room temperature in another bowl and soak first piece of bread. Be careful and do it very very quickly, otherwise bread may break down.

Squeeze the bread piece gently and place it on a plate.

Apply some cocoa paste. Now sprinkle some grated white chocolate.

Place the another piece on it after soaking it in milk. Apply cocoa paste and sprinkle white chocolate.

Repeat the same process upto 5 pieces.

When it comes to 6th piece, likewise soak it in the milk and place on the 5th one. But don't apply cocoa paste or sprinkle grated white chocolate over it.

Now it's a time for the chocolate sauce. Spread the chocolate sauce on the top i.e. on 6th layer evenly.

Garnish with chopped white chocolate and chocolate chips. Place it in the refrigerator for some time to get firm and chilled.

bread pastry is ready.
