Place the oats on a baking sheet, drizzle with the honey and stir around a little. Toast under a preheated medium grill for about 6–8 minutes, turning occasionally, until golden, watching carefully to ensure they do not burn. Transfer to a plate to cool slightly.
Gently mix together the toasted oats, yogurt, whisky, if using, and raspberries in a bowl until just combined – do not over-mix.
Divide between 4 small bowls or glasses and serve drizzled with extra honey.
