01 - Preheat the oven to 265°F (130°C).
02 - In a mixing bowl, whisk together coconut milk, almond milk, chia seeds, maple syrup, vanilla extract, and sea salt until fully incorporated.
03 - Let the mixture rest for 10 minutes, then whisk again to prevent clumps.
04 - Pour the mixture into a shallow ovenproof dish made of glass or ceramic.
05 - Cover the dish tightly with aluminum foil and place in the preheated oven.
06 - Slow roast for 2 hours, stirring gently every 30 minutes to achieve even texture; pudding is ready when thickened and chia seeds are swollen.
07 - Remove from oven and cool at room temperature. For chilled pudding, refrigerate at least 2 hours.
08 - Spoon pudding into bowls or jars and garnish with toasted coconut flakes, fresh berries, chopped nuts, and an optional drizzle of maple syrup.
