In a mixing bowl, whisk together rolled oats and chia seeds until combined.

Pour in your favorite milk into the oat mixture and stir gently until fully incorporated.

Gently fold in fresh blueberries, being careful not to burst them.

Cover the bowl with plastic wrap or transfer to an airtight container and refrigerate for at least 6 hours or overnight.

Once rested, portion the mixture into jars or containers for quick serving.

Before serving, stir and adjust consistency with a splash of milk if needed. Serve chilled topped with additional blueberries or honey.
