Cut each celery stalk into 3-4 inch pieces, creating sturdy boats for the almond butter.
Pat the celery pieces completely dry with a paper towel to help the almond butter stick better.
Spread about 1-2 tablespoons of almond butter into the center groove of each celery piece, filling generously.
Sprinkle the filled celery sticks with hemp seeds, chia seeds, and a pinch of sea salt.
If desired, add a light dusting of cinnamon on top and serve immediately, or store covered in the refrigerator for up to 3 days.
