Crush Oreos in chunky bits, not powdered. Layer them at the bottom of your serving dish for a chocolatey, bold base.
Prepare a robust, spiced coffee with cardamom or a pinch of cinnamon. Allow it to cool slightly and use it to soak the Oreo layers.
Whip heavy cream with a hint of condensed milk until it's smooth and thick. This provides a sweet, rich Indian-style flavor without being overpowering.
Fast and furiously dunk additional Oreos into the coffee that has been brewed and spoon over the layers on top of the cream. Repeat until your dish is completed to the rim.
Chill the tiramisu for not less than 4 hours. Sprinkle some cocoa powder dust on top, then sprinkle some crushed pistachios as the final desi flourish.
