Ingredients and Substitutions

For the exact measurements and detailed instructions, please see the recipe card below.

Banana, oats, peanut butter, milk, and sweetener are the ingredients for this overnight oats recipe.
  • Optional add-ins. You can include whatever you want, really. Try Greek yogurt, protein powder, spices, or nuts.
  • Oats. Be sure to get old-fashioned rolled oats. They will maintain their texture after soaking all night and won’t get mushy like quick oats tend to, or remain firm like steel-cut oats. (Are oats gluten-free? Learn all about them!)
  • Milk. You can use any type of milk you like. Both regular and dairy-free work. Cashew milk is my go-to since it is super creamy and tastes great in this recipe. But almond milk, oat milk, soy milk, and regular milk can all be used.
  • Peanut Butter. Opt for a creamy, natural peanut butter variety. If you use crunchy, there will be hard bits of peanut throughout the oatmeal.
  • Banana. Steer clear of an overly ripe banana, or your oatmeal will be very mushy, and it won’t last as long. Sliced bananas are needed for this recipe.
  • Sweetener. The best option is pure maple syrup, followed by honey. These natural sweeteners add subtle flavor without being overwhelming. You can use regular sugar or brown sugar if needed.
  • Chia Seeds. You don’t have to add these, but they provide a wonderful, creamy consistency and extra health benefits.

FAQs

What type of jars to use?

The best type of jar to use is an 8-ounce Mason jar. These are the perfect size for individual servings, and they have a tight-fitting lid that will keep the ingredients fresh.

How long do overnight oats last?

Overnight oats can easily last up to 3 to 4 days in the fridge. However, they will start to get mushy after the first 24 hours. To ensure fresh and delicious oatmeal, wait to mix in the milk until the night before you serve it.

Do I serve overnight oats warm or chilled?

You can enjoy overnight oats either warm or cold, whatever you prefer! They are delicious either way. If you choose to warm them up, pop them in the microwave for about a minute. You might need to add some extra milk to get the consistency you like.
