Preheat oven to 175°C. Line a 25 x 38 cm jelly roll pan with parchment paper, ensuring overhang at edges.

In a large bowl, combine chocolate cake mix, eggs, vegetable oil, water, and vanilla extract. Beat until the batter is completely smooth.

Pour batter into the prepared pan and spread evenly. Bake for 12 to 15 minutes, or until a toothpick inserted in the centre comes out clean.

While the cake bakes, lay a clean kitchen towel flat and dust generously with powdered sugar.

When baked, immediately invert the hot cake onto the sugared towel. Remove the parchment. Carefully roll the cake from the short end with the towel inside. Allow to cool fully in rolled form.

In a mixing bowl, beat cream cheese and unsalted butter until smooth. Gradually add powdered sugar and vanilla extract; mix until uniform. Fold in crushed Oreo cookies delicately.

Gently unroll the completely cooled cake. Spread the Oreo cream cheese filling evenly, leaving the outermost edge clean. Roll the cake up tightly, this time without the towel.

Wrap the filled roll snugly in plastic film. Refrigerate for at least 60 minutes or until fully set.

Melt white chocolate and drizzle over the chilled roll. Garnish with whole or additional crushed Oreo cookies. Slice with a sharp knife and serve cold.
