Lightly toast the oatmeal either in a dry skillet/frying pan or on a baking sheet/tray under a broiler/grill. It will take a few minutes, but you should start to smell it become a little nutty. Take care not to let it burn. Set aside to cool as you prepare the rest.
Whip the cream to at least soft peak, if not a little firmer. Gently mash the raspberries - you don't want them completely pureed but at least letting some juice out and a bit broken.
Fold the whisky and honey into the cream, ensuring well mixed but without making the cream too runny. Fold in the oatmeal, saving ½tbsp to top. Then fold in the raspberries and transfer to serving glasses/bowls.

Notes
Note - some recipes will have you soak the oatmeal in half the whisky overnight. This will give it a softer texture and it will tend to taste more of whisky doing this. Prepare as you prefer - I prefer as above as it is lighter and has a nice slightly crunchy texture (and is quicker!). You can also layer the cream and raspberries which will look a little prettier but it's more traditionally mixed. One nice compromise is to fold in around half to two thirds, and use the rest to make a raspberry 'band' in the middle as you put in the glass.
