What Are Overnight Oats?
As the name suggests, overnight oats are an oatmeal recipe made in advance, usually overnight.
You can prepare them ahead of time - depending on what type of oats you are using, you can make the meal any time between 1 hour and 4 hours beforehand.
You absolutely can leave them to soak overnight, which will result in a richer and fuller flavour of the final dish.
If you are batch cooking, feel free to make this breakfast even a few days ahead. Always remember to use the freshest ingredients possible when doing so, to prolong the shelf life. And please, keep the final product in the fridge.

Key Ingredients and Substitutions
This recipe contains only 6 ingredients, most of which you will find in your pantry (store cupboard). You will need:
- Old-fashioned oats (oat flakes), also known as rolled or Scottish oats, a great source of fibre and many valuable minerals and vitamins, which are good for your heart and blood pressure. Porridge oats, and quick (instant) oats will work here too;
- Oreo biscuits or similar, look for 'cookies and cream' alternative in your grocery store,
- Plant-based Greek-style yogurt as a source of protein;
- Unsweetened oat milk, soy or almond milk to add an extra bit of moisture;
- Sugar-free chocolate sauce (syrup) or honey and cocoa powder for extra sweet chocolatey flavour;
- Ground nutmeg helps improve your immunity, gut, brain and overall health.
Choose plant-based plain yogurt instead of the same amount as the recipe suggests for both Greek-style yogurt and oat milk. The texture of the overnight oats will be similar.
Feel free to use cold boiled water if you prefer to omit adding plant-based yogurt and milk altogether.
See the recipe card (below) for exact measurements of all ingredients used.
This recipe is for 1 serving. Feel free to multiply everything by the number of portions if prepping breakfast in batches.

About Calories in This Recipe
Scrolling down to the nutrition card, you may notice that a portion of these overnight oats has got roughly 500 calories. This is mainly due to the Oreo cookies which are indeed sugary.
If you wish to lower the calorie count, but still want to enjoy this delicious breakfast, use just a half of the biscuits.
Alternatively, opt for sugar-free or 'zero sugar' options of chocolate and cream sandwich biscuits.
FAQs
What oats are best for overnight oats?
You can use any type of oats that you have on hand: rolled oats, old-fashioned oats, jumbo oats or even quick (instant) oats. The final texture will differ depending on the oats used in the recipe - the bigger the grain, the chewier and denser they will be and vice versa.
Yes, overnight oats can be beneficial to your diet. Oats contain a high amount of fiber, which helps your heart and blood pressure. Use sugar-free sweetener or sauce to make it sweeter.
For a lactose-free recipe, use plant-based yogurt and milk. If you wish to skip the milk altogether, add cold water instead (1:1 ratio), or use only plant-based plain yogurt (not Greek-style, which is normally much thicker; use the same amount as the recipe suggests for both yogurt and milk).
