Here is my favorite blueberry overnight oats recipe, made with creamy coconut milk, chia seeds, maple syrup, and a touch of vanilla for a breakfast that’s ready when you wake up.

These overnight oats have become my go-to on busy mornings when I need something healthy and filling but don’t have time to cook. I prep a few jars on Sunday night, and breakfast is sorted for half the week. Plus, the kids actually eat them without complaining, which is a win in my book.

What Kind of Coconut Milk Should I Use?

For this recipe, you’ll want to grab the canned full-fat coconut milk, not the carton kind you find in the refrigerated section. The canned version is much thicker and creamier, which gives your overnight oats that rich, satisfying texture that makes them feel like dessert for breakfast. If you only have light coconut milk on hand, it’ll still work, but your oats might be a bit thinner and less creamy. Just make sure to give the can a good shake before opening it, as the cream and liquid tend to separate while sitting on the shelf.

Options for Substitutions

This recipe is super forgiving and works well with different ingredients you might already have:

Coconut milk: If you’re not a fan of coconut or don’t have it on hand, regular milk, almond milk, oat milk, or soy milk all work great. Just keep in mind that coconut milk gives these oats a creamier texture, so other milks might be slightly thinner.
Frozen blueberries: Fresh blueberries work just as well, or you can swap in other berries like strawberries, raspberries, or blackberries. Mixed berries are also a nice option if you want variety.
Rolled oats: Stick with rolled oats for this recipe – quick oats will get too mushy, and steel-cut oats won’t soften properly overnight without cooking.
Maple syrup: Honey, agave nectar, or even a mashed banana can replace the maple syrup. You can also skip the sweetener entirely if your berries are sweet enough or if you prefer less sugar.
Chia seeds: Ground flaxseed works as a substitute and adds similar thickness and nutrition. Use the same amount as the chia seeds.

Watch Out for These Mistakes While Making

The biggest mistake with overnight oats is not using enough liquid, which leaves you with a thick, paste-like texture instead of creamy oats – if your mixture looks too thick after stirring, add an extra splash of coconut milk before refrigerating.

Another common error is skipping the chia seeds or not mixing them in well, since they help thicken the oats and create that satisfying, pudding-like consistency you’re looking for.

Make sure to give your jars a good stir before putting them in the fridge and again in the morning, as the oats and chia seeds tend to settle at the bottom and can create uneven texture.

For the creamiest results, let your oats sit for at least 6 hours rather than the minimum 3 – this gives the oats plenty of time to soften and absorb all those blueberry flavors from the coconut milk.

What to Serve With Blueberry Overnight Oats?

These overnight oats are pretty filling on their own, but I love adding a handful of sliced almonds or chopped walnuts on top for some extra crunch and protein to keep me full until lunch. A drizzle of almond butter or peanut butter also works great if you want to make it even more satisfying. If you’re serving this for brunch or want to make it feel more special, fresh fruit like sliced bananas, strawberries, or extra blueberries on the side adds a nice touch. You could also pair it with a hard-boiled egg or some Greek yogurt if you want more protein to round out your breakfast.

Storage Instructions

Store: These overnight oats are perfect for meal prep! Keep them in an airtight container or mason jar in the fridge for up to 5 days. I usually make a big batch on Sunday and have breakfast ready to grab all week long.

Make Ahead: The beauty of overnight oats is that they’re meant to be made ahead. Just mix everything together the night before and let the oats soak up all that creamy coconut milk while you sleep. They actually taste better after sitting for at least 8 hours, so don’t skip this step!

Serve: You can enjoy these straight from the fridge for a cool, refreshing breakfast, or warm them up in the microwave for about 30-45 seconds if you prefer them cozy. Add your fresh toppings right before eating so they stay nice and crunchy.

Ingredients

1/2 tsp vanilla extract (pure vanilla for best flavor)
1/4 cup shredded coconut (unsweetened preferred)
2 tbsp maple syrup (or honey as a substitute)
1 cup rolled oats (old-fashioned oats for better texture)
1 can coconut milk (13.5 fl oz, I use Thai Kitchen brand)
2 tbsp chia seeds (adds thickness and nutrition)
1 cup frozen blueberries (fresh or frozen work equally well)

Step 1: Prepare the Blueberry-Coconut Base

1 can coconut milk
1 cup frozen blueberries

Pour the can of coconut milk into a blender with the frozen blueberries and blend until completely smooth and combined.

This creates a rich, fruity base that will infuse the oats with flavor.

The frozen blueberries will thicken the coconut milk slightly and give it a beautiful purple hue.

I like to blend until there are no visible berry pieces—this helps the texture stay creamy throughout the night.

Step 2: Mix the Overnight Oats

1 cup rolled oats
2 tbsp chia seeds
2 tbsp maple syrup
1/2 tsp vanilla extract
blueberry-coconut mixture from Step 1

In a bowl or measuring cup, combine the rolled oats, chia seeds, maple syrup, and vanilla extract.

Stir these dry and wet ingredients together until evenly distributed.

This ensures the sweetness and vanilla flavor are balanced throughout the oats.

Then divide this mixture evenly between two jars (or containers of similar size).

Pour the blueberry-coconut mixture from Step 1 over the oat mixture in each jar and stir well to combine, making sure the oats are fully submerged and no dry pockets remain.

Step 3: Chill and Set Overnight

Cover both jars with lids or plastic wrap and refrigerate for at least 3 hours, though overnight (8 hours or more) is ideal.

During this time, the oats will absorb the liquid, the chia seeds will expand and create a creamy texture, and all the flavors will meld together beautifully.

The longer it sits, the thicker and more pudding-like the consistency becomes.

Step 4: Finish and Serve

Remove the jars from the fridge and give them a good stir.

If the oats seem too thick, add a splash more coconut milk or milk of your choice to reach your preferred consistency.

Taste and add another drizzle of maple syrup if you’d like it sweeter.

I find that chilling overnight sometimes mutes the sweetness slightly, so don’t be shy about tasting before serving.

Divide between bowls and top each serving with a handful of shredded coconut and a few fresh or thawed blueberries for color and texture contrast.
