In a medium bowl, combine the rolled oats, chia seeds, yogurt, milk, and honey. Stir well until everything is evenly mixed and smooth.

Spoon half of the oat mixture into the bottom of two mason jars or other sealable containers, spreading it into an even layer.

In a small bowl, use a fork to mash the raspberries until they’re broken down and jammy. Divide the mashed raspberries evenly between the two jars, spooning them on top of the oat layer.

Spoon the remaining oat mixture over the raspberries to create the final layer. Smooth the tops if desired.

Seal the jars with lids and refrigerate overnight, or for at least 6 hours. These oats will keep well in the fridge for up to 5 days. Stir before eating and top with extra fruit, granola, or your favorite add-ins if you’d like.
