Customize – Overnight Oats are perfect to customize with different flavors and spices such as pumpkin pie spice, apple pie spice, or toppings such as fruits and chocolate chips. Get creative and choose your favorite version of overnight oats!
Consistency is Key – If you prefer a thinner version, add more liquid, or if yours seems too thick, add more liquid. If you prefer thick, add less liquid or more thickening ingredients such as chia seeds or protein powder.

Make it Sweet – If you want it sweet, start with the sweetener in the recipe card below, then add additional sugar, honey, or sweetener to your preference.

How do you store overnight oats?

These need to be stored in an airtight container, a mason jar works the best. These can be stored in the refrigerator for up to 5 days. When ready to serve, serve straight out of the mason jar or heat before serving.
