In a large mixing bowl, whisk together the almond milk, chia seeds, maple syrup, and vanilla extract until well combined.

Fold in the mixed berries, ensuring they are evenly distributed throughout the mixture.

Cover the bowl and refrigerate for at least 2 hours, or overnight for a thicker consistency.

Stir the pudding before serving, and divide it into four serving bowls or jars.

Top with additional berries or nuts for an added crunch.
