Raspberries: Fresh or frozen raspberries will work. Frozen berries may need slightly longer in the microwave and can release a little more liquid.

Protein powder: Vanilla whey works particularly well, but use your favourite flavour or leave it out if preferred. If yours tends to go grainy when mixed directly into thick yoghurt, smoothing it with a little warm water or milk first makes it much easier to incorporate.

Greek yoghurt: I use a thick fat free Greek yoghurt such as Fage. Vanilla Skyr would also work if you prefer something a little sweeter and less tart.

Honey: Maple syrup or your preferred liquid sweetener can be used instead.

Seeds: Use any mixed seeds you have pumpkin, sunflower, linseed or additional chia seeds would all work.
