Mix the milk, chia seeds, vanilla extract, and cinnamon in a wide and shallow bowl. Place the bowl in the fridge for 10 minutes so the chia seeds thicken.
Add vegan butter to a pan over medium heat. A non-stick pan will work best.
Dip a slice of bread into the batter on one side for 10 seconds, then dip it on the other side for 10 seconds.
Place the bread on the pan. Repeat with 1-2 more slices. Bread should be spaced out enough that the slices are not touching each other.
Cook until the bottom is a light golden brown, for approximately 4 minutes. Flip each slice, then cook the other side for an additional 3-4 minutes until it's a light golden brown too.
Remove from pan and place on serving dish. Between batches, add more butter to the pan as needed. You can also mix in an extra sprinkle of cinnamon to the batter bowl between dipping slices.
Serve with maple syrup and fresh berries! Enjoy while warm.
Notes
When selecting a gluten-free bread, thicker breads will be better for french toast. Sandwich bread will work, but it may not hold together as well or can get a little soggy. If you'd like to keep this recipe paleo, select a bread that is paleo.
Store leftovers in an airtight container in the fridge. The french toast slices can also be frozen.
If you don't have vegan butter, you can use an oil such as coconut or avocado oil.
If you don't like the texture of chia seeds, be sure to grind them using a coffee grinder or herb grinder.
Option to sprinkle extra cinnamon and mix into the batter in between dipping slices.
