Prep the mango: Peel and dice 1 large ripe mango. Set aside about half for topping.
Mash or blend the rest into a smooth puree. If the mango isn’t very sweet, stir in 1–2 teaspoons of maple syrup and a small squeeze of lime.
Mix the base: In a medium bowl or jar, whisk together 1 cup milk, 3 tablespoons chia seeds, 1–2 teaspoons sweetener (optional), 1/2 teaspoon vanilla extract, and a small pinch of salt.
Add mango flavor: Stir in 2–3 tablespoons of the mango puree to lightly flavor the pudding. Save the rest of the puree for layering.
Stir, rest, stir again: Let the mixture sit for 5–10 minutes, then whisk again to break up any clumps.
This step helps the chia absorb liquid evenly.
Chill to set: Cover and refrigerate for at least 2 hours, preferably overnight, until thick and creamy.
Assemble: Spoon a layer of mango puree into the bottom of a bowl or jar, add the chia pudding, and top with diced mango. Add any toppings you like.
Taste and adjust: If you prefer it sweeter or looser, drizzle a little extra sweetener or whisk in a splash of milk right before serving.
