Take 10 of your 12 Oreo cookies and break them into large chunks. Don’t crush them too much; bigger pieces will make the shake taste better. Set aside the other 2 cookies for later. Break a Cadbury Dairy Milk chocolate bar into small pieces and melt it.

You can melt it in the microwave in 20-second intervals. Stir each time until it’s smooth. Let it cool for a minute before adding it to the blender.

Start by pouring 2 cups of cold milk into the blender. Next, add broken Oreo cookies, melted chocolate, and ¼ cup of sugar. If you prefer a thicker shake, add some ice cubes now. Blend everything on medium-high for 30 to 45 seconds.

If it’s too thick, add a little milk. If it’s too thin, add another scoop of ice cream or a few more ice cubes and blend for another 10 seconds.

Taste the shake. If you want it sweeter, add more sugar or some chocolate syrup and blend for 5 more seconds. If you want a stronger Oreo flavor, add one more cookie and pulse quickly.

Pour the shake into a tall glass. Add whipped cream on top, drizzle with chocolate syrup, and sprinkle crushed Oreo crumbs.

Crush the 2 reserved cookies and sprinkle them on top. Serve the shake cold and fresh. Hand it over with a wide straw and enjoy the thick chocolate flavor before it gets thin.
