Back to school time means busy mornings trying to get out the door on time. With two toddlers starting preschool (have you ever tried to get a toddler to do anything fast?), I'm relying on make-ahead breakfasts to make our mornings as smooth as possible. This peanut butter banana overnight oats recipe is one that I know I can always count on for the whole family to enjoy, and I feel good about serving it!

Why You'll Love These Overnight Oats

Everyone loves the classic peanut butter banana combination! The genius of overnight oats is that you get the wholesome goodness of oatmeal with the convenience of a grab-and-go breakfast that can be eaten warm. All with just 5 minutes of prep time and 7 simple ingredients. And they're filling enough to power you through a busy morning.

What Makes This A Healthy Breakfast?

We all know that oatmeal is super healthy - it's got soluble and insoluble fiber, for both digestive health and heart health. All that fiber also makes oatmeal filling while providing steady, lasting energy. Plain greek yogurt and milk offer up 22 grams of protein per serving, while delicious peanut butter and chia seeds provide healthy fat. This recipe also has no added sugar - it's sweetened only with banana (so it's baby friendly, for my BLW mamas!)

Ingredients:

• Bananas - Provide natural sweetness and potassium. The more ripe (brown) the bananas, the sweeter your oats will be.
• Peanut butter (of course!) - My favorite is peanut butter made with just peanuts and salt, such as Crazy Richard's or the Costco brand, for the best peanut flavor.
• Plain Greek yogurt - Yogurt produces a thick, creamy texture and boosts the protein content without protein powder.
• Milk - I use regular milk for the nutrition content. If you are going to use non-dairy milk, look for one with similar protein content as cow's milk, like soy milk.
• Oats - Use rolled oats (old fashioned oats) for the best texture. If you don't have rolled oats, you can use quick oats or quick cooking steel cut oats.
• Chia Seeds - For a little boost of omega-3s. If you don't like the texture of chia seeds, you can sub in ground flaxseed or just leave them out.
• Cinnamon - Just a pinch for a sweet flavor without any actual sugar.

What Makes This Recipe High in Protein?

This Peanut Butter Banana Overnight Oats recipe packs a dose of protein thanks to a combination of healthy ingredients:

• Rolled Oats: While oats are typically known for their fiber content, they also contribute a decent amount of protein. A cup of rolled oats adds about 11 grams of protein to the recipe, making them a great base for a protein-packed breakfast.
• Greek Yogurt: Greek yogurt is one of the best sources of protein among dairy products. It adds a creamy texture to the oats and significantly boosts the protein content. We use plain Greek yogurt, which provides around 10 grams of protein per half-cup serving.
• Peanut Butter: Natural peanut butter not only adds a delicious nutty flavor but also contributes healthy fats and about 8 grams of protein per 2 tablespoons. It’s a great way to add both taste and nutrition!
• Chia Seeds: These tiny seeds are a powerhouse of nutrients, including protein. A tablespoon of chia seeds adds about 2 grams of protein along with fiber and omega-3 fatty acids, making your oats more filling and nutritious.
• Milk: Using regular milk (or a high-protein plant-based milk like soy milk) adds another 7.5 grams of protein per cup. This contributes to the overall creamy texture and nutritional value of the oats.

By combining these ingredients, you get a well-rounded, high-protein meal that will keep you full and energized throughout the morning. Plus, this recipe is versatile! You can customize it with your favorite protein-rich ingredients, such as other nut butters or even a scoop of protein powder if you want an extra boost.
