You can also use alternative sweeteners like honey or maple syrup. Feel free to experiment with different fruit toppings such as berries, mangoes, or peaches. For a vegan version, ensure that the sugar and vanilla extract you use are vegan-friendly. The chia pudding can be stored in an airtight container in the refrigerator for up to 3 days.
