SERVINGS

METHOD · 6 STEPS

mix · ~2 min
Mix the wet ingredients.
In a large mixing bowl, whisk together the milk, yogurt, maple syrup, vanilla extract, cinnamon powder, and salt until smooth and well combined.
mix · ~2 min
Fold in the oats and chia seeds.
Add the rolled oats and chia seeds to the wet mixture. Stir thoroughly with a spoon until everything is evenly distributed and no dry spots remain.
mix · ~1 min
Gently fold in the blueberries.
Add 1 cup of the blueberries to the oat mixture. Fold them in gently to avoid breaking the berries.
TIPIf using frozen blueberries, add them straight from the freezer — they'll thaw overnight and streak the oats a beautiful purple.
assemble · ~2 min
Portion the oats into jars.
Divide the oat mixture evenly among four 16-ounce mason jars. Press down lightly to submerge all oats in liquid. Seal with lids.
TIPPress down gently — this ensures every oat absorbs liquid for the creamiest texture.
rest
Refrigerate overnight.
Place the sealed jars in the refrigerator. Let the oats soak for at least 6 hours, preferably overnight, until thick and creamy.
TIPThe oats are ready at 6 hours but hit peak creaminess around 8-10 hours.
assemble · ~1 min
Top with remaining blueberries and walnuts before serving.
When ready to eat, top each jar with the reserved fresh blueberries and a generous sprinkle of chopped walnuts. Serve cold straight from the fridge.

PRO TIPS

What to keep in mind.

6 tips from the recipe — small details that make a real difference to the final dish.

1
Toast the walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant to deepen their nutty flavor.
2
Use a 1:1 ratio of milk to oats for the creamiest texture — this recipe already nails it.
3
If you prefer a thinner consistency, add an extra 2-3 tablespoons of milk before serving and stir.
4
For a natural purple swirl, mash half the blueberries before folding them into the oat mixture.
5
Make a batch on Sunday for up to 5 days of grab-and-go breakfasts — the oats hold up well.
6
Let the oats sit at room temperature for 5 minutes before eating if you don't like them ice-cold.

Swap the milk for almond or oat milk and use a plant-based yogurt (coconut or soy). The texture remains creamy, and the maple syrup keeps it sweet without honey.
