Prepare the Batter: In a large mixing bowl, whisk together the all-purpose flour, sugar, cardamom powder, and chopped nuts until well combined.

Mix Wet Ingredients: In a separate bowl, cream the softened butter until light and fluffy. Add the condensed milk, mixing until smooth and fully incorporated.

Combine Dry and Wet Ingredients: Gradually fold the dry mixture into the wet mixture. Gently mix until just combined.

Bake: Line a cupcake tray with liners and fill each with the batter, about two-thirds full. Bake them at 350°F (175°C) for 18-20 minutes.

Cool: Once baked, remove the cupcakes from the oven and let them cool in the tray for about 5 minutes before transferring them to a wire rack to cool completely.

Decorate: Once fully cooled, adorn your cupcakes with edible silver leaf and additional chopped nuts for a festive touch.
