Combine almond milk, chia seeds, cashews, 2 tablespoons cacao nibs, maple syrup, cocoa powder, vanilla extract, sea salt, and cinnamon, in a high-speed blender. Blend until well combined, 30 seconds to 1 minute. Stir in 1 tablespoon cacao nibs and pour into individual bowls. Cover and refrigerate for 1 hour or overnight. Mixture will thicken as it chills.
Sprinkle pudding with remaining cacao nibs before serving.
