Everything for these blueberry muffin overnight oats comes together right inside a single mason jar with zero cooking required. Five minutes of quick mixing before bed gives you a cool breakfast that tastes just like a bakery muffin.
Old fashioned rolled oats soak up milk and tangy yogurt while ground nutmeg delivers that cozy baked flavor. Fresh whole blueberries add bursts of sweetness in every bite.
Step-by-Step Instructions
1. Combine Base Ingredients
Add the rolled oats, milk, natural yogurt, and ground nutmeg into a clean mason jar. Skip the blueberries for now so they stay whole while mixing.
2. Stir Until Smooth
Stir the oat mixture thoroughly with a spoon until the yogurt and nutmeg blend evenly into the milk. Make sure no dry oats remain trapped at the bottom of the jar.
3. Add Fresh Blueberries
Fold in the whole blueberries gently on top of the oat mixture. Keeping them whole prevents excess juice from making the oats soggy overnight.
4. Chill Overnight
Seal the jar tightly with its lid and place it in the refrigerator at 40°F (5°C). Let the oats rest overnight for at least 8 hours until the mixture thickens into a creamy pudding.
Tips & Tricks
- Use a standard eight ounce jar so you have enough room to stir without spilling.
- Crush a small graham cracker over the top right before serving if you want extra bakery texture.
Variations
Graham Cracker Crunch
Sprinkle crushed graham crackers on top just before eating for a baked muffin top texture.
Nutty Crunch

How to Store Blueberry Muffin Overnight Oats
Refrigerator
Keep covered in the refrigerator at 40°F (5°C) for up to 3 days.
Freezer
Freezing is not recommended because the fresh blueberries and yogurt break down upon thawing.
Reheating
Serve cold straight from the fridge, or warm in the microwave for 30 seconds if you prefer hot oats.
Frequently Asked Questions
Q: Can I use steel cut oats instead of rolled oats?
Steel cut oats remain too tough when soaked cold overnight. Stick with old fashioned rolled oats for the ideal tender bite.
Q: Can I use frozen blueberries?
Yes, frozen blueberries work well. They will soften as they thaw overnight and color the oats purple, which tastes great.
