🥘 Ingredients

It’s super easy to make a batch of healthy peanut butter banana overnight oats. Most of these wholesome items are pantry staples, and if not, they are easily found at your local grocery store!

• Steel Cut Oats: The star of these pb banana overnight oats, steel cut oats provide a heartier texture than their quick or old-fashioned counterparts. Pre-cooked, they soften overnight resulting in creamy oats with a delicious soft yet chewy consistency. They’re also a great source of fiber and protein.
• Milk: The type of milk you choose is a matter of personal preference. Whether you opt for almond milk, soy milk, oat milk, or regular dairy, it’s the key to creating that creamy texture we love in overnight oats.
• Plain Low Fat Greek Yogurt: Adding a protein punch and a rich texture, Greek yogurt is a nutritious breakfast staple. It also helps to keep you feeling full until lunch.
• Peanut Butter: This ingredient is a game changer for all the peanut butter lovers out there. Natural peanut butter adds healthy fats and a creamy richness. Plus, it is the perfect partner for the ripe banana in this recipe.
• Ground Flax Seed & Sea Salt: Flax seeds are a powerhouse of nutrition, offering both fiber and omega-3 fatty acids. They give a slightly nutty flavor and help to thicken the mixture. Just a pinch of sea salt can help to enhance the other flavors in this oatmeal recipe.
• Sliced Berries: Fresh fruit adds a natural sweetness and a burst of flavor to this banana peanut butter overnight oatmeal. Strawberries are a classic choice, but feel free to get creative based on your favorite things.
• Banana: The banana combo with peanut butter is a classic combination. Ripe bananas add natural sweetness and a creamy texture.
• Sliced Almonds Or Walnuts: A sprinkle of sliced almonds or walnuts adds a delicious crunch and an extra boost of healthy fats.
• Cinnamon And Nutmeg: These spices are optional, but they add a warm, comforting flavor that pairs beautifully with the banana and peanut butter.

🍲 Ingredient Substitutions

• Oats: You can use any kind of oats such as old-fashioned oats or certified gluten-free oats if you have a gluten sensitivity. I won’t recommend quick cooking oats since they are quite processed will get mushy in this recipe.
• Milk: Any non-dairy milk like almond milk, cashew milk, or coconut milk can be used as a substitute. You can also use cow’s milk if you do not need this to be vegan!
• Yogurt: You can use any plant-based yogurt as a substitute. Make sure to choose an unsweetened version to control the sweetness of your overnight oats.
• Nut Butter: Don’t have peanut butter, or have a peanut allergy? No problem! Cashew butter, almond butter, or even sunflower seed butter all work great. Go with whatever you have on hand and customize the flavors. If you still want that regular peanut butter taste, use peanut butter powder for a lower-fat / lower calorie option.
• Chia Seeds: Chia seeds can be a great substitute for flax seeds. Both provide a good amount of fiber and healthy fats.
• Nuts: Any kind of nuts can be used based on your preference. You can also use seeds if you have a nut allergy.
• Spices: These spices are optional but they add a nice flavor to the oats. Feel free to use your favorite spices or leave them out if you prefer. Some good swaps are clove, allspice, or a pumpkin pie spice.

🔪 How To Make Peanut Butter Banana Overnight Oats

Want the perfect breakfast that’s ready to go in to morning? Here’s how to make peanut butter banana overnight oats, your new favorite make-ahead breakfast solution! For more detailed instructions and nutritional information, see the recipe card at the bottom of this post.

Cook The Steel Cut Oats: Start by cooking your steel cut oats. This is an important step, otherwise they won’t be the texture you are probably going for. They will puff up as they sit overnight but will be pretty crunchy by morning unless they are pre-cooked.

Combine Ingredients: Once your oats are cooked, combine them with the rest of the ingredients through the ripe banana, either in a medium bowl or directly in the mason jar or airtight container. Give the ingredients a good stir until it is well combined.

Refrigerate: Next, place your container in the fridge and let it sit overnight. This allows the flavors to meld together and the oats to soften, creating a delicious breakfast for the next morning.

Add Toppings: When you’re ready to eat, add a tablespoon of sliced almonds or walnuts and a sprinkle of cinnamon or nutmeg. Add additional sliced bananas, if desired. Stir it all together and enjoy these banana pb overnight oats!

💭 Expert Tips

• Pre-Cook Your Steel-Cut Oats: Steel-cut oats require a longer cooking time than other types of oats. To ensure a softer, creamier texture in your peanut butter banana overnight oats, cook your steel-cut oats ahead of time.
• Save The Toppings For The Next Morning: To maintain the freshness and crunch of your toppings, add them just before you’re ready to eat your delicious breakfast. Toppings can turn soggy if left overnight.
• Get The Liquid-To-Oats Ratio Right: The secret to perfect overnight oats is getting the right balance of liquid to oats. If you skimp on the liquid, your oats won’t be able to absorb enough to become creamy and delicious.
• Mix Well Before Refrigeration: To guarantee that every oat gets a good soak, give your mixture a good stir before popping it into the fridge. This will help all the oats to be equally immersed in the liquid, leading to a consistent texture throughout.
• Boost Of Sweetness: If you want your oats to be a touch more sweet, feel free to add in some pure maple syrup or a drizzle of honey.

🍽 Serving Suggestions

This recipe for peanut butter banana overnight oats is great on its own, or pairs well with other breakfast recipes. Here are some of my top serving suggestions:

• With A Smoothie: For a power-packed breakfast, serve these peanut banana overnight oats with a smoothie. Try a broccoli smoothie for an extra boost of nutrients or a mixed berry smoothie for a sweet start to your day. 
• Alongside Protein: To increase the protein content of your breakfast, pair these oats with a side of scrambled eggs or a boiled egg. Keep things vegan with a soft tofu scrambled eggs.

🙌 Dietary Adaptations

This banana peanut butter overnight oats recipe is already a healthy breakfast option, but with some simple ingredient swaps, it can be adapted to suit a variety of dietary needs.

• Vegan And Dairy-Free Option: To make this easy recipe vegan, substitute the Greek yogurt with a plant-based yogurt of your choice. Almond milk yogurt or soy milk yogurt would work well. Also, make sure you pick a non-dairy milk!
• Gluten-Free Option: You can make this recipe gluten-free by using certified gluten-free oats. Always check the labels when purchasing oats, as some brands may process their oats in facilities that also process wheat, which could lead to cross-contamination.
• Nut-Free Option: If you’re catering to a nut allergy, substitute the almond or peanut butter with a seed butter like sunflower seed butter. Also, go for nut-free milk such as oat milk or soy milk. Skip the nut toppings, and try out pumpkin seeds or more berries!

🫙 Storage Directions

• Refrigerating: After enjoying these healthy overnight oats, you can store any leftovers in an airtight container in the refrigerator. Alternatively, you can meal prep and store it for later. They can be kept for up to three days.
• Freezing: Unfortunately, freezing these overnight oats is not recommended. The Greek yogurt used in the recipe does not freeze and defrost well, resulting in a less desirable consistency upon thawing.
• Reheating: If you prefer a warm breakfast, these peanut butter and banana overnight oats can be reheated. Transfer the oats to a microwave-safe bowl and heat them for approximately one minute. If the oats appear too dry, feel free to add an extra splash of milk. Alternatively, you can warm them on the stove in a small pot.
