Pour all the base dry ingredients and base liquid ingredients into a mason jar (8 ounces or larger). Add any optional dry ingredients desired, and/or any optional liquid ingredients to the jar as well. You can add one optional ingredient, multiple optional ingredients, or none. The optional ingredients (and spice) allow you to customize the oats to your liking.
Stir the ingredients until well combined. Refrigerate the oats overnight. The oats may be kept in the fridge for 2-3 days. Alternatively, you can make multiple jars of dry oat mixes, seal the jars, and store them away in the pantry or fridge until you're ready to add the liquid ingredients. Once the liquid is added, store the oats in the fridge and serve within 2-3 days.
To enjoy, add any optional toppings to the top of the oats. I personally like to top my oats with a nut butter, banana or berries, and hemp seeds. Enjoy. This recipe makes enough for one serving (1 cup).
Notes
* A few of my favorite spice options: cinnamon, pumpkin pie spice, cardamom, nutmeg (only a few pinches, not 1/2 tsp), cloves (only a pinch or two, not 1/2 tsp), ginger (only a pinch or two, not 1/2 tsp). You can also add in turmeric powder, if desired. If adding turmeric, start with 1/4 tsp since the taste is potent. You can also mix spices to create a custom flavor profile. Calorie Count Disclaimer: The nutrition facts are for every ingredient listed. While I believe in nourishing ingredients over counting calories, we do provide calorie information to keep Google happy. That said, in this situation, if you're looking at the calorie information, the count isn't accurate unless you added every single ingredient listed here to your overnight oats.
