1. Help the kids measure out and whisk together the almond milk, honey, cinnamon, and vanilla extract in a medium bowl until well combined. Add the chia seeds and set aside for 15 minutes.
2. Whisk the almond milk mixture again to redistribute any chia seeds that may have settled, then divide the mixture among four 6-oz. ramekins or small jars. Cover and refrigerate overnight. Serve topped with toasted almonds and fresh blackberries.
