Take a bowl and transfer the crushed oreos in it. Now to that add 1 tsp coffee diluted with some water and cocoa powder. Adding coffee and cocoa powder to it is optional you can skip it.

Now gradually add 1/4 cup milk and keep it whisking continuesly. Now add 1/2 tsp baking powder and 1/4 tsp baking soda. Mix it well and transfer it into the cake mould greased with some oil and lined with butter paper.bake the cake at preheated at 180°C for 15 - 20 mins

By the time prepare the Ganache. Take a cup of dark/milk chocolate. Now melt it using a double boiler method. (for that boil some water in a vessel and put another larger vessel over it. Put the Chocholate in the larger vessel and it will melt from the heated vapours.) if you want add a tsp of butter for a batter taste.

Now after 15 mins the cake was ready. I checked it by inserting a toothpick. If it comes clean, the cake is ready.

Now for preparing the syrup, take some chocholate syrup and dilute it with some water.

Put another layer over it and repeat the same process as done in the previous one. Like that assemble all pastry and let it freeze for about 10 mins. After 10 mins level up the cake with a spatula.

Now take the removed cream from oreo biscuits and pipe them using a piping bag and nozzle. Decorate it with a peice of oreo and chocholate savings. Now again freeze it for an hour. Serve it with some cold coffee. Uuum yummy

Yummy oreo pastry is ready. I made it for my dad on the fathers day and he loved it. Hope you're dad's will too love.
