Overnight oats with Formula 1
Written by Rachel Orriss | Last updated July 2026
Overnight oats are useful because breakfast is already waiting in the fridge. Formula 1 can be used as the flavour part of the mix, especially if you want a vanilla, banana or chocolate-style base without making a shake in the morning.
The point is not to turn oats into a complicated recipe. Keep the bowl simple, make the texture nice, and use products only where they add something.

How to make Formula 1 overnight oats
Here is the simple version to start with. Add 50g rolled oats to a jar or bowl, then pour in around 200ml milk or unsweetened plant milk. Stir in one serving of Formula 1 Vanilla Cream or Formula 1 Banana Cream until the powder is fully mixed through and there are no dry patches at the bottom.
If you like a thicker, creamier pot, add two spoonfuls of plain yoghurt before chilling. If you want it more filling, add a small serving of Protein Drink Mix as well, then use an extra splash of milk so the oats still soften properly overnight.
Cover the jar and leave it in the fridge for at least 6 hours, ideally overnight. In the morning, stir it again and loosen with a little more milk if needed. Top with banana slices, berries, apple, cinnamon or a spoonful of yoghurt. Keep the toppings simple so the Formula 1 flavour still comes through.
A good first combination is Vanilla Cream, oats, milk, yoghurt and berries. For a warmer breakfast flavour, use Banana Cream with sliced banana and cinnamon. Once you know the texture you like, you can make two or three jars at once for the next few mornings.
Simple base recipe
Use oats, milk or a milk alternative, yoghurt if you like it thicker, and one serving of Formula 1 for flavour. Stir until the powder is fully mixed in, cover it, then leave it in the fridge overnight. In the morning, loosen it with a splash of liquid if it is too thick.
Banana, berries, apple, cinnamon and a spoon of yoghurt all work well. If you want a more filling version, add Protein Drink Mix, but do not add every extra at once. Build the recipe around taste first.
Texture tips
If the oats taste powdery, they usually needed more liquid or more stirring before chilling. If they taste too sweet, add plain yoghurt or fresh fruit. If they are too thick, add liquid after chilling rather than trying to guess the perfect amount the night before.
Vanilla Cream is the easiest all-rounder. Banana Cream works well with banana slices or cinnamon. Chocolate flavours work better with yoghurt, berries or a small spoon of nut butter.
Three easy versions
For a fruit bowl, use Vanilla Cream, oats, yoghurt, berries and enough milk to loosen it. For a banana breakfast, use Banana Cream, chopped banana, oats and cinnamon. For a higher-protein version, use Formula 1 with Protein Drink Mix and keep the toppings simple.
Make one jar first before batch-prepping several. Once the texture and flavour work, it becomes an easy repeat breakfast for work mornings.
What not to overdo
Overnight oats can become heavy if every topping goes in at once. Nut butter, granola, honey, dried fruit and chocolate extras all add up quickly. Choose the flavour direction first, then add one or two extras at most.
Formula 1 should make the recipe easier, not turn breakfast into a long list of ingredients.
Formula 1 oat combinations
| Flavour route | Good with | Why it works |
|---|---|---|
| Vanilla Cream | Berries, banana, apple, yoghurt. | Neutral base and easy to repeat. |
| Banana Cream | Banana, cinnamon, oats, yoghurt. | Breakfast-style flavour without much effort. |
| Smooth Chocolate | Greek-style yoghurt, berries, nut butter. | More dessert-style, but still simple. |
| Protein Drink Mix add-on | Any flavour when you want more protein. | Useful add-on, but not needed for every bowl. |

Questions about Overnight Oats with Formula 1
Can I put Formula 1 in overnight oats?
Yes, many people use it for flavour in a cold oat mix. Add it with the liquid and stir well so the texture is even.
Which flavour works best?
Vanilla Cream and Banana Cream are the easiest starting points because they work with fruit, yoghurt and oats without fighting the flavour.
Do I still need protein powder?
Only if you want the recipe to be higher in protein. Protein Drink Mix is an add-on, not a must-have for every bowl.
Can I make it the night before?
Yes. Overnight oats are best mixed and chilled so the oats soften before breakfast.
