The day before, add chia seed, almond milk, and maple syrup into a large mixing bowl and whisk to evenly combine the seed into the liquid.
Film the bowl with plastic wrap or a silicone lid and place it in the fridge for 1 hour. After that time, whisk the mixture again to unstick the seeds and prevent them from gravitating to the bottom of the jar and forming lumps. Film again and refrigerate overnight.
Serve the next days with toppings you love - fresh berries, a drizzle of peanut butter, or chopped nuts.
Store up to 3 days in a sealed mason jar in the fridge.
