Line a baking tray with parchment paper and set it aside for the shaped pinecones.

Crush 1 packet of Parle-G biscuits into a fine, sand-like crumb using a rolling pin.

Combine the crushed biscuits with 3 tbsp cocoa powder in the mixing bowl.

Stir 3 tbsp sweetened condensed milk into the biscuit mixture until it starts to clump together.

Add 3/4 tbsp milk and knead the mixture into a firm, moldable chocolate dough.

If the dough remains dry or crumbly, mix in 1 tbsp melted butter until it holds together.

Divide the dough into 10 equal portions and roll each portion into an oval pinecone-shaped base.

Press cornflakes into each dough base in overlapping rows, starting at the bottom and working upward to create pinecone scales.

Chill the finished pinecones in the refrigerator until firm enough to serve.
