For the full ingredient measurements, scroll down to view the recipe card at the bottom of the page.
- Almond milk, or other plant-based milk.

- Vanilla extract, a hint of vanilla tastes really good in this overnight oats.
- Rolled oats, or old fashion oats, they hold their shape and create texture in your overnight oats. I don’t recommend using quick cooking oats.

- Cinnamon, a hint of warming cinnamon pares so well with the other flavours.

Storage
This brown sugar overnight oats recipe will keep for about 5 days, if stored in an airtight container in the fridge. That’s why this recipe is perfect for a healthy meal-prep breakfast!
Just keep in mind that the longer the overnight oats sit, the more liquid the oats will soak up and you will end up with a thicker texture. If needed, you can stir in a little extra milk just before serving.
Overnight oats doesn’t freeze well, so I don’t recommend this.
Top Tip
Overnight oats are usually served cold straight out of the fridge. But they can also be served warm. Heat one portion of these brown sugar overnight oats in the microwave in 30 sec intervals until it is piping hot. The consistency might get a little thicker when heated, a suggestion is to serve them with a little extra milk. Add your favorit toppings and enjoy!
