Mash the berries: In a bowl, lightly mash the raspberries with a fork to release their juices. Leave some chunks for texture.
Whisk the base: In a separate medium bowl, whisk coconut milk, maple syrup, vanilla, and a pinch of salt until smooth.
If the coconut milk is separated, whisk well to combine the cream and liquid.
Add chia seeds: Stir in the chia seeds and mashed raspberries. Mix thoroughly so no clumps of seeds remain.
Let it thicken: Cover and refrigerate for 10 minutes. Remove, stir again to redistribute the seeds, then return to the fridge.
Chill fully: Refrigerate for at least 2 hours, or overnight for a thicker set.
The pudding should be spoonable and creamy.
Serve: Spoon into bowls or jars and top with extra raspberries and your favorite add-ons. Taste and add a drizzle of syrup if you prefer it sweeter.
