The simple ingredients you need to make this easy recipe for overnight oats include:
- 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 favorite go-to since it is super creamy and tastes really good 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 add a wonderful, creamy consistency along with extra health benefits.
- Optional add-ins. You can include whatever you want, really. Try Greek yogurt, protein powder, spices, or nuts.
How to Make Peanut Butter Banana Overnight Oats
These are the steps to follow to make this easy overnight oats recipe:
Add the Peanut Butter and Banana to the Jar
Opt for 8-ounce jars; they are the easiest to find and will fit a full serving of these overnight oats.
Add the creamy peanut butter and banana slices to the bottom of the mason jar.
Combine Remaining Ingredients
Carefully add the oats, chia seeds, milk, and sweetener into the jar with the peanut butter and bananas.
Use a spoon to gently stir the ingredients until everything is mixed well.
Refrigerate to Set
Screw the lid on the jar then set it in the fridge.
Be sure to let it chill for at least 4 hours, but overnight is best.
Serve with your favorite toppings, like toasted pecans, toasted walnuts, spices, an extra drizzle of peanut butter, fresh banana, or even chocolate chips.
Meal Prep and Storage
- To prep and store: It is so simple to prepare this dish entirely the evening before. Once it’s mixed, it will keep in the fridge in an airtight, resealable container for up to 3 to 4 days. However, after the first 24 hours, the oatmeal will get mushy. You can prep extra by waiting to mix the milk in until the night before you serve it.
- To freeze: Freezing is not recommended. The creamy texture of the oats will not be the same and instead will be too watery.
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.
Are overnight oats healthy?
These peanut butter banana overnight oats are super healthy because they are full of nutritional and filling ingredients. In general, be careful of extra add-ins, as those can increase the calorie and sugar amounts. The natural sweetness of the simple peanut butter-banana combination makes the perfect breakfast.
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 the milk in until the night before you will be serving 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.
The recipe you’ll find below is already gluten-free and vegetarian as written. Here are some adjustments and substitutions you can make to help it fit your other dietary requirements:
- Dairy-free. Stick with a plant-based milk.
- Nut-free. Sub in a nut-free butter, like sunflower seed butter.
Expert Tips and Tricks
- Roll out. Rolled oats are the best option to ensure a creamy and smooth consistency.
- Mix and chill. Combine all of the ingredients in the Mason jar to save dishes and keep things simple.
- Go for extras. Optional add-ins like yogurt, protein powder, spices, or nuts add so much to the oatmeal.
- Keep it cool. These overnight oats need at least 4 hours in the fridge, but they’re better after a full night in the fridge.
- Big batch. Add everything to the jars except milk at the beginning of the week to be ready for breakfast every day.
