Set aside 2-3 resealable jars. If making one large serving, set aside one large jar.
Add all ingredients to the jar(s) of your choice, leaving enough room to stir. Or, add all ingredients to a mixing bowl for easier stirring, then pour into jars when done.
Stir until well mixed. Add any optional toppings except fruit. Seal jars.
Store overnight in the refrigerator for up to 5 days. Overnight oats will become thicker as each day passes. If desired, add non-dairy milk to thin it out. Enjoy cold, or heat in the microwave in 20-second increments until warm. Top with fruit before serving.
Notes
*I prefer using coconut cream in overnight oats—it lends a thick, creamy and delicious texture. If using non-dairy yogurt, make sure to choose your favorite kind—the flavor will be very present. Use vanilla yogurt for a tasty addition!
