The mixture should look slightly looser than you want the final texture, as the oats, chia seeds and protein powder will absorb liquid overnight. Different protein powders vary in thickness, so if the oats feel very thick in the morning, simply stir through a small splash of milk to loosen.

If using frozen raspberries, there’s no need to defrost they will soften overnight and release juices into the oats naturally.

The protein powder can be omitted if preferred. If leaving it out, reduce the milk slightly (use around 30-40ml instead of 50ml) or add an extra tablespoon of Greek yoghurt to maintain a thick, creamy texture. You may also wish to add a little extra sweetener to taste, as protein powder adds sweetness.
