In a medium bowl or jar, whisk together 1 cup of milk, 1/4 cup chia seeds, a sweetener of your choice, and 1 teaspoon of vanilla extract. Stir vigorously for 30-60 seconds until well combined. Cover and refrigerate for at least 4 hours, or ideally overnight, until thickened.

While the chia pudding is chilling, peel and dice half of a ripe mango. Purée the remaining half until smooth to create a silky mango layer. Hull and slice fresh strawberries, mashing a few to create a jam-like texture.

Once the chia pudding has thickened, start layering in serving cups. Spoon a layer of chia pudding, followed by mango purée, then a dollop of the strawberry mix. Repeat to create multiple layers, finishing with fresh fruit on top.

Place the assembled cups back in the refrigerator for an additional 30 minutes to meld flavors, allowing them to chill.

After chilling, serve the chia pudding cups for breakfast, snack, or dessert. Garnish with optional toppings like coconut flakes, granola, or fresh mint leaves.
