In a medium-sized mixing bowl, combine the chia seeds, unsweetened almond milk, cocoa powder, maple syrup, vanilla extract, and a pinch of sea salt.
Using a whisk, vigorously mix the ingredients for about 2 to 3 minutes to ensure complete incorporation. Make sure there are no lumps of cocoa powder left unmixed.
After mixing, allow the pudding to sit undisturbed for 10 minutes. Then, whisk it again to break up any clumps of chia seeds that may have formed during the initial resting period.
Once again combined, you have the option to either cover the bowl with plastic wrap or portion the mixture into individual serving cups for ease.
Refrigerate the pudding for a minimum of 4 hours, or preferably overnight. This chilling period allows the chia seeds to absorb the liquid, resulting in a delightful thick texture.
When ready to serve, stir the pudding well. If the pudding is too thick for your liking, feel free to add a splash more almond milk, mixing until you achieve your desired consistency.
To serve, generously top the pudding with an assortment of fresh berries and a sprinkle of chopped nuts for a delightful crunch and burst of flavor.
