Preheat your oven to 180°C (fan) and line two baking trays with greaseproof paper.

Lightly roll out the puff pastry sheets on a floured surface, and cut into rectangles of approximately 4"x2.5".

Pipe or spread a generous amount of vegan Nutella into the center of each rectangle, add banana slices, and brush edges with dairy-free milk.

Lay narrow strips of pastry across the filling in a zig-zag pattern to create a mummy look.

Brush the tops of the hand pies with more dairy-free milk and sprinkle with granulated sugar.

Bake the hand pies for 15 to 18 minutes until golden brown and puffy.

Cool on a wire rack for a few minutes before adding decorations.
