Preheat the oven to 200°C (180°C fan-forced).
Take the ice cream out of the freezer to soften.
Mix the breadcrumbs, nuts and mixed spice together in a bowl, then spread out evenly on a shallow baking tray lined with baking paper. Bake for 8 to 10 minutes until the mixture turns golden.
Mix the breadcrumbs into the softened ice cream, then return the freezer. Allow a couple of hours for the ice cream to firm up before serving.
Add a few extra toasted nuts on top if you like.
