01 - In a medium mixing bowl, whisk together the cocoa powder, chia seeds, chopped hazelnuts, and salt until evenly distributed.
02 - Pour in the almond milk, maple syrup, and vanilla extract. Whisk vigorously until the mixture is completely smooth and no cocoa lumps remain.
03 - Let the mixture sit for 5 minutes to allow the chia seeds to begin absorbing the liquid, then whisk again thoroughly to break up any clumps.
04 - Cover the bowl with plastic wrap or a lid and refrigerate for at least 4 hours, or overnight, until the pudding reaches a thick, creamy consistency.
05 - Stir the chilled pudding well to redistribute any settled ingredients. Spoon into individual serving bowls or jars.
06 - Top with extra chopped hazelnuts, dairy-free chocolate shavings, or fresh berries as desired. Serve chilled.
