In a medium bowl, combine the strawberries, milk, yogurt, vanilla extract, and maple syrup. Use an immersion blender to blend the mixture until smooth. Alternatively, you can blend the ingredients in a standing blender and transfer the mixture to a bowl.
Stir in the chia seeds thoroughly to ensure even distribution.
Cover and refrigerate for at least 4 hours or overnight, allowing the chia seeds to absorb the liquid and thicken into a pudding-like texture.
Serve chilled, topped with fresh strawberries, additional fruit, or whipped cream, if desired.
