Ingredients and Substitutions
Rolled Oats
Rolled oats work best because they soften overnight while staying chewy. Quick oats can get mushy.
Chia Seeds
These help thicken the oats and create a creamy texture.
Soy Milk
Soy milk adds extra protein, but any milk works.
Yogurt
You can use plain yogurt, coconut yogurt, or vanilla yogurt.
Vanilla Protein Powder
Vanilla flavor works best with blueberries, but plain protein powder also works.
Maple Syrup
Honey or agave syrup can be used instead.
Lemon Juice
This brightens the blueberry flavor and adds freshness.
Blueberries
Fresh or frozen blueberries both work great.
Why This Recipe Works (Quick Science)
The oats absorb the liquid overnight, which softens them without cooking. Chia seeds soak up moisture and naturally thicken the mixture. Protein powder and yogurt increase the protein while helping create a creamy texture. Blending the blueberries into the milk spreads berry flavor through every bite.
Instructions
Step 1: Add the Dry Ingredients
Add ½ cup rolled oats, 1 tablespoon chia seeds, and 2 tablespoons vanilla protein powder into each glass jar. Stir together.

Step 2: Blend the Blueberry Milk
Add 1 ½ cups soy milk, 1 ½ cups blueberries, 9 tablespoons yogurt, 3 tablespoons maple syrup, and 3 teaspoons lemon juice into a blender. Blend until smooth and creamy.

Step 3: Pour and Stir
Pour the blueberry milk mixture evenly into the jars with the oat mixture. Stir very well until combined.

Step 4: Refrigerate Overnight
Cover the jars with lids and refrigerate for at least 6 hours or overnight until thick and creamy.
Step 5: Add Toppings and Serve
Top each jar with fresh blueberries and sliced almonds before serving.
