Dairy Free Overnight Oats with Coconut Milk and Mango

There is something genuinely exciting about opening the fridge in the morning to find breakfast already done. These dairy free overnight oats with coconut milk and mango do exactly that. You spend about five minutes putting them together the night before, and by morning you have a thick, creamy, tropical jar of goodness waiting for you. No cooking, no rushing, no stress. Just scoop, eat and get on with your day.
What makes this recipe stand out from the crowd is the nutritional profile. A lot of overnight oats recipes lean heavily on sweeteners, flavoured yogurts and sugary toppings, which quietly turns a healthy breakfast into a dessert. This version takes a different approach. The creaminess comes from full-fat light coconut milk blended with unsweetened almond milk, which keeps the fat content balanced while delivering that rich, velvety texture you want. Rolled oats bring serious fibre to the table, which means you stay full for longer and avoid that mid-morning energy crash. A scoop of vanilla plant-based protein powder is stirred right into the base, bumping up the protein to around 22 grams per serving without any chalky aftertaste. Chia seeds add another layer of fibre, plus omega-3 fatty acids and a gentle thickening effect that makes the oats almost pudding-like by morning.
The mango topping is where the real magic happens. Fresh mango is naturally sweet, loaded with vitamin C and beta-carotene, and it brings a bright, sunny flavour that transforms this from a plain oat jar into something you genuinely look forward to eating. A squeeze of fresh lime juice over the mango cuts through the richness of the coconut and keeps the whole thing feeling light and vibrant. A pinch of turmeric stirred into the oat base adds a subtle warmth, supports the anti-inflammatory benefits and gives the oats a beautiful golden hue. Toasted coconut flakes and a small handful of chopped macadamia nuts go on top for crunch and healthy fats. The whole combination tastes like a tropical holiday in a jar. If fresh mango is out of season, frozen mango works brilliantly here. Just thaw it overnight in the fridge alongside the oats and it will be perfectly soft and juicy by morning.
This recipe is completely dairy free, egg free, vegan and naturally gluten free if you use certified gluten-free oats. It works beautifully as a weekly meal prep staple. You can line up four jars on a Sunday evening, fill them all in one go and have breakfast sorted for most of the week. Each jar keeps well in the fridge for up to four days, and the texture actually improves after the first night as the oats continue to absorb the liquid and become even creamier. If you prefer a thinner consistency, simply stir in a splash of almond milk in the morning before adding your toppings. This is one of those recipes that fits seamlessly into a busy lifestyle, supports your health goals and genuinely tastes great. Once you try the coconut and mango combination, it is hard to go back to plain overnight oats.
Ingredients
- 1 cup rolled oats (use certified gluten-free oats if needed)
- 3 cup light coconut milk (canned, full-fat light variety works best)
- 1 cup unsweetened almond milk (or any other unsweetened plant-based milk)
- 2 tbsp chia seeds
- 2 scoops vanilla plant-based protein powder (approximately 50g total, pea or rice protein both work well)
- 1 tbsp pure maple syrup (adjust to taste or omit if your protein powder is sweet enough)
- 1 tsp ground turmeric
- 1 tsp vanilla extract
- 1 pinch fine sea salt
- 1 cup fresh mango (diced into small cubes, approximately 1 medium mango)
- 1 tbsp fresh lime juice (from roughly half a lime)
- 2 tbsp unsweetened toasted coconut flakes (for topping)
- 2 tbsp raw macadamia nuts (roughly chopped, for topping)
Instructions
- 1
Add the rolled oats, chia seeds, vanilla plant-based protein powder, ground turmeric, vanilla extract and a pinch of sea salt to a medium mixing bowl. Stir everything together so the dry ingredients are evenly combined.
Mixing the dry ingredients first helps the protein powder distribute evenly without clumping when the liquid goes in.
- 2
Pour in the light coconut milk, unsweetened almond milk and maple syrup. Stir thoroughly for about one minute until no dry pockets remain and the mixture looks smooth and uniform.
Taste the liquid mixture at this point and adjust the maple syrup to your preference before the oats absorb everything overnight.
- 3
Divide the oat mixture evenly between two clean glass jars or airtight containers. Seal with lids and place in the fridge for a minimum of 8 hours, or overnight.
Mason jars with wide mouths are the easiest to fill, stir in the morning and eat straight from.
- 4
While the oats chill, place the diced mango in a small bowl and toss with the fresh lime juice. Cover and refrigerate separately until morning.
Storing the mango separately keeps it fresh and prevents it from making the oats watery overnight.
- 5
In the morning, remove the jars from the fridge. If the oats are thicker than you like, stir in a splash of almond milk to loosen them up. Give everything a good stir.
- 6
Spoon the lime-tossed mango generously over the top of each jar. Scatter the toasted coconut flakes and chopped macadamia nuts over the mango. Serve immediately straight from the jar.
Add the toppings just before eating so the coconut flakes and nuts keep their crunch.

Pro Tips
- ✓
Use certified gluten-free rolled oats if you are coeliac or highly sensitive to gluten cross-contamination.
- ✓
Full-fat light coconut milk strikes the best balance between creaminess and calorie count. Coconut cream makes the oats very rich, while coconut water makes them too thin.
- ✓
Frozen mango cubes work just as well as fresh. Thaw them in a covered bowl in the fridge overnight alongside the oats.
- ✓
If your plant-based protein powder is already sweetened or vanilla-flavoured, skip the maple syrup entirely and taste before adding any extra.
- ✓
Batch prep four jars at once on Sunday for four days of effortless breakfasts. Just keep the toppings separate until you are ready to eat.
- ✓
A tablespoon of hemp seeds stirred into the base adds extra protein and omega-3s with barely any change to the flavour.
Frequently Asked Questions
Variations
- •
Mango Passionfruit
Scoop the pulp of one passionfruit over the mango topping for an extra burst of tropical flavour and a beautiful tangy contrast to the creamy coconut base.
- •
Mango Ginger
Stir a quarter teaspoon of freshly grated ginger into the oat base alongside the turmeric. The warmth of the ginger pairs beautifully with the sweet mango and brightens the whole flavour profile.
- •
Pineapple and Mango
Swap half the mango for diced fresh pineapple to create a more complex tropical topping. Pineapple also contains bromelain, a natural enzyme that supports digestion.
- •
High Protein Mango Overnight Oats
Stir two tablespoons of hemp seeds and one tablespoon of almond butter into the base before chilling. This takes the protein content well above 28 grams per serving and adds extra healthy fats.
Substitutions
- •Almond milk → Oat milk, soy milk or macadamia milk (Any unsweetened plant-based milk works. Soy milk adds the most protein. Oat milk gives a slightly sweeter flavour.)
- •Light coconut milk → Full-fat coconut milk (Full-fat coconut milk creates a richer, more indulgent result but increases the calorie and fat content noticeably.)
- •Maple syrup → Medjool date paste, agave nectar or raw honey (Date paste adds fibre alongside sweetness. Raw honey is not vegan but works well for non-vegan versions.)
- •Plant-based protein powder → Two tablespoons of hemp seeds plus one tablespoon of almond butter (This lowers the protein slightly but keeps the recipe whole-food based with no powders required.)
- •Macadamia nuts → Sliced almonds, chopped cashews or pumpkin seeds (Pumpkin seeds make this recipe nut-free and are an excellent source of zinc and magnesium.)
- •Fresh mango → Frozen mango, thawed overnight (Frozen mango is nutritionally identical to fresh and is available year-round. Thaw in the fridge the same night you prep the oats.)
🧊 Storage
Store the oat base in sealed jars or airtight containers in the fridge for up to 4 days. Keep the mango topping in a separate covered bowl and add fresh each morning. Do not freeze overnight oats as the texture becomes grainy and watery once thawed.
📅 Make Ahead
This recipe is designed for make-ahead preparation. Prep up to four jars in one batch on a Sunday evening and refrigerate. The texture actually improves after the first night as the oats fully hydrate. Simply add fresh toppings each morning before eating.
