🍒 Ingredients
All the ingredients and their quantities are set out in the recipe card below.
Some notes on a few of them:
- Oats - it is best to use rolled oats / old fashioned oats for overnight oats rather than quick-cook or steel cut oats.
- Frozen berries - use blueberries, raspberries or other frozen fruit such as redcurrants, blackcurrants or perhaps some frozen mango.
- Chia seeds - I suggest using whole chia seeds rather than milled chia.
🍎 Toppings for your frozen berry overnight oats
Whether you like a bit of crunch or extra sweetness, you can always add fun toppings when serving your oats. Some ideas:
Nuts and seeds - such as pumpkin seeds and flaked almonds.
Extra fruit - whether fresh or frozen, add even more sweet treats to your oats!
Desiccated coconut - or coconut flakes for a creamy flavour.
📋 Swaps and variations
Use frozen berries of your choice. There are many options, including blueberries and blackberries or even cranberries.
Leave out the cinnamon. Some love a little hint of spice, but it can easily be left out of this recipe.
🔪 Step by step instructions
Making frozen berry overnight oats is perfect for meal prep, and has just a few steps.
Option 1:
Steps 1 & 2
Pour the non-dairy milk, chia seeds and cinnamon into a bowl, as well as the oats. Give it a good stir or whisk to combine (images 1 & 2).
Steps 3 & 4
Add the frozen berries and maple syrup to the bowl, and stir very well so they are evenly mixed into the oat mixture (image 3 & 4). Place in the fridge for at least two hours, or overnight.
Option 2: See below in the recipe card for how to make layered overnight oats!
💭 Recipe tips and notes
- Always give overnight oats a good stir or whisk, so all the ingredients combine and the oats and chia seeds can soak up the milk.
- Don't worry about thawing the berries before adding to the oat mixture. They will thaw in the fridge as you allow the oats to soak.
- If the oats are too dry for your personal taste you can always add a dash more milk just before serving.
📖 Frequently asked questions
Rolled oats (also called old fashioned oats) are the best kind for overnight oats. Steel cut oats can be used but will need to be soaked for longer, and will still have quite a lot of 'bite' to them.
Most fruits should work well, especially berries or mango.
I don't suggest using a lot more chia in the recipe as it can make the oats quite gelatinous in texture, and taste quite 'earthy'.

📖 Recipe
Frozen Berry Overnight Oats
Equipment
- Bowl or jars
Ingredients
- 1 cup oats
- 1 cup frozen berries
- 1.25 cups non-dairy milk
- 1 tablespoon chia seeds
- 1 tablespoon maple syrup
- ½ teaspoon cinnamon optional
Instructions
- Option 1: Pour the milk into a bowl or tupperware that can be sealed. Add the oats, chia seeds and cinnamon and stir or whisk to combine. Then add the maple syrup and frozen berries and stir well again.
- Option 2: To layer the overnight oats, follow option one, but add half the frozen berries to the oat mixture. Add the other half to your serving bowl or jar.
- Place both the bowls in the fridge for at least two hours, or longer if suitable. If you can, give the oat mixture a stir after about an hour. Adjust with more milk, if you wish for a looser consistency.
- Spoon the oat mixture on top of the frozen fruit (if following option 2) and add toppings of your choice.
Notes
- You can either layer the berries and oats, by having berries at the bottom of your bowl or jar and then topping with the oat mixture, or combine all together.
- Be sure to stir very thoroughly so the chia seeds and oats can soak up the milk and the juices from the fruit as it thaws.
- Don't worry about thawing the berries first, the beauty of this breakfast is that is thaws in the fridge as the oats soak!
- If you like quite a loose texture, then add a dash more milk as you serve them.
- See above in the recipe post for some ideas for fun toppings!
