My favorite toppings include blueberries (fresh or frozen), raisins, “Elvis Style” (sliced bananas and peanut butter), or chopped apples with cinnamon. All of these options taste even better with some toasted pecans. :)
If you want a superfood boost, try stirring chia seeds or ground flaxseed into the oats right before serving.
Occasionally, overnight oats will develop a greenish coating on top. It's due to a harmless chemical reaction between the oats and water that has a high pH. Just give your oats a good stir in the morning and carry on with breakfast.
This recipe can be doubled (or tripled!) if you use a larger pot. The cooked oats also freeze well.
