Crush the Oreos

• Blitz the Oreo cookies in a food processor until finely crushed.
• Set aside a little of the crumbs for sprinkling.

Make the base

• Mix the crushed Oreos with the melted butter until the crumbs hold together.
• Press the mixture firmly into the cups of a muffin pan to form a base and sides.

Prepare the creamy filling

• Beat the cream cheese with the powdered sugar until smooth.
• Fold in the Nutella until evenly combined.

Fill the cups

• Spoon the Nutella cream into the Oreo cups, leaving a small hollow in the center.
• Add a small extra spoonful of Nutella in the middle for a gooey core.

Chill or bake

• Chill the cups in the fridge until firm, or bake them briefly at 180 °C for a softer, gooier result.

Finish and serve

• Drizzle the melted milk chocolate over the chilled cups.
• Sprinkle with the reserved Oreo crumbs and serve.
