In a large mixing bowl combine your yogurt, chia seeds, maple syrup, vanilla extract, nut butter, and milk. Whisk really well. Then whisk some more. Chia seeds need to be very well combined for the best results.
Refrigerate overnight.
Once your chia seed pudding is ready, divide it equally among 4 jars.
If desired you may drizzle 1 teaspoon additional nut butter on top like I did (mostly for aesthetics) so there's a little tucked under the chocolate shell for looks.
Melt your chocolate together with the coconut oil in a double boiler OR in the microwave, stirring every 20 seconds. This creates your chocolate shell mixture.
Pour a thin layer of your chocolate shell over each chia seed pudding and sprinkle very lightly with flaky sea salt. Place in the refrigerator for at least 20 minutes so the shell hardens.
Keep refrigerated until ready to serve, but no more than 5 days.
Enjoy!
