🥣 How to make (step-by-step photos)

1️⃣ Step One: Blend blueberries

To do this, simply add sliced blueberries, plant-based milk, maple syrup, and vanilla extract to a high powered blender and blend until smooth (alternatively, you can also add all ingredients to a bowl and use a handheld immersion blender).

👉 Pro tip: While many blueberry overnight oats recipes are simply just unflavored overnight oats with blueberries on top, in this recipe we’re going to flavor the oats themselves by blending blueberries and mixing with the oats.

2️⃣ Step Two: Mix overnight oat ingredients

Then pour the blended blueberry mixture over the oats, then close the jar with a lid and shake well to mix the ingredients.

👉 Container tip: If you don’t have a jar, you can alternatively mix the ingredients in a bowl and then add to a small glass.

4️⃣ Step Four: Garnish and serve

When you’re ready to eat the oats, simply remove the jar or glass from the refrigerator, top with garnishes like blueberries or granola, and enjoy!

❓ Recipe questions + quick tips

What are the best plant-based milks for overnight oats?

Some of the best plant-based milks for overnight oats are almond milk, coconut milk, and oat milk, as they have a creamy texture and subtle flavors that complement the oats well.

How long should I soak the oats overnight for the best texture?

For the best texture, it is recommended to soak the oats in plant-based milk overnight for at least 4-6 hours or ideally up to 12 hours, as this allows the oats to absorb the liquid and soften to a creamy consistency.
