Take 12 Oreo biscuits on a plate
Remove all cream from Oreo biscuits and keep it aside in a bowl.
Break 5 oreo biscuits into pieces. (don't make too small pieces, roughly break them)And keep aside in a separate bowl.
Blend the remaining 7 Oreo biscuits in a mixer blender for 1 minute. (Don't make too fine powder) and transfer it to a bowl and add 1 tablespoon of clarified butter in powdered Oreo biscuits and mix well, keep aside.
Now mix 2 tablespoons cornflour, 2 tablespoons of milk powder, 2 tablespoons sugar, cream of Oreo biscuits,4-5 drops vanilla essence, and 2-3 tablespoons of lukewarm or room temperature milk and mix well.
Further, boil the milk in a heavy bottom cooking pot on a medium flame
Once the milk gets boiled lower the gas flame and add this mixture of cornflour with all ingredients in it. Then milk started becoming thicker (it takes 2-3 minutes). Turn off the gas flame. Then transfer half of the mixture of pudding to a heat-resistant bowl.
Add ½ teaspoon coffee powder and 75 gm Dairy milk or dark chocolate in the remaining half mixture of pudding and cook it on lower flame, until the chocolate gets Dissolved completely. (It takes 1-2 minutes).
Once all chocolate Dissolved completely turn off the gas flame and remove it into another heat-resistant bowl.
As both the mixture of the puddings is hot, let it cool down. You can keep the bowl in cold water.
Once both the mixture cools down up to room temperature.
Add the crushed Oreo biscuits to a white mixture and mix gently.
Now take two serving glasses.
Fill 2 teaspoons of powdered Oreo biscuits mixture at the bottom of both the serving glasses and press it with the help of a spoon or disposable glass as I have done.
Further, pour half-half chocolate pudding mixture in both the glasses and spread the remaining 2 teaspoons of powdered Oreo biscuits over it.
Put these glasses in the freezer for 30 minutes for setting this pudding.
After 30 minutes remove the glasses from the freezer and now spread half-half white Oreo pudding mixture.
At last spread 1 teaspoon chocolate syrup and choco chips on white Oreo pudding mixture.
Again put these glasses in the freezer for 30 minutes for setting pudding.
After 30 minutes remove the glasses from the freezer.Your Oreo pudding is ready to serve.
Garnish with Oreo biscuits and serve chilled and enjoy.
