Combine the almond milk, protein powder, cocoa powder, vanilla, maple syrup, and salt in a bowl or jar, whisking until smooth.
Incorporate the chia seeds by stirring them in.
Allow the mixture to rest for 5 minutes, then stir again to ensure even distribution of the chia seeds.
Cover and refrigerate for at least 2 hours, or overnight for optimal thickness.
Before serving, stir again and add your favorite toppings like dairy-free yogurt, dark chocolate shavings, fresh berries, or a spoonful of peanut butter.
