Add the ingredients to a medium bowl and stir well.
Cover and refrigerate, or divide into smaller containers, cover, and refrigerate for at least four hours or overnight. The mixture will firm up into a pudding-like texture as the chia seeds absorb the liquid and plump up.
Serve cold with berries, if desired.
Notes
Store in an airtight container for up to a week in the fridge. This is best served cold.
Use ground chia seeds for a smoother final consistency. Note that they are sometimes more bitter tasting.
Use nondairy yogurt as needed.
Have for breakfast or snack as you like.
Top with whipped cream if desired.
Serve with strawberries or other fruit on top if desired.
