Wash and hull the strawberries, then blend them into a smooth purée. If using frozen berries, thaw them completely first.
In a medium bowl, whisk together your milk, vanilla extract, maple syrup, and a pinch of salt.
Slowly add the chia seeds to the liquid mixture while whisking continuously to prevent clumping.
Gently fold in the strawberry purée, creating swirls throughout the mixture. For a layered effect, you can reserve some purée for layering when serving.
Transfer the mixture to individual jars or a covered container and refrigerate for at least 4 hours or overnight.
Before serving, stir the pudding and check the consistency. If too thick, add a little more milk; if too thin, add more chia seeds and wait 30 minutes.
Serve chilled with optional toppings such as fresh strawberry slices, granola, or mint leaves.
