Oatmeal has easily become one of my preferred everyday choices for a healthy breakfast. It’s quick for busy mornings, plus, it’s a perfect post-workout meal that helps me sustain my energy throughout the day. One way to keep oatmeal more interesting is to rotate different flavor combinations regularly. Just like our High-Protein Creamy Oatmeal, this Peanut Butter Banana Oatmeal has become a recent favorite that I actually look forward to!

What Makes This Oatmeal Stand Out

Oatmeal is one of those foods that can either be exciting or bland, depending on how you flavor it. Here are some of the reasons this oatmeal tastes great every time.

It’s naturally sweet thanks to the mashed banana, so you may not need much additional sweetener.

It’s high in protein. Peanut butter powder and soy milk help bring this high-protein oatmeal to 25 grams of plant-based protein per serving.

It is vegan and gluten-free. Just be sure to choose oats labeled gluten-free to avoid cross-contamination.

This Peanut Butter Banana Oatmeal is quick and easy for a simple weekday breakfast option.

Other Ways to Use Peanut Butter Powder

Peanut butter powder is a great alternative to regular peanut butter. It’s low in calories, yet still high in protein. You can mix it with water to make it easily spreadable for whole grain toast or a bagel. Other ways to use peanut butter powder:

• Cookie or Muffin Mix – Add to your favorite cookie or muffin mix by replacing a small portion of the flour with the peanut butter powder. (Check for recipes online to get specific ratios.)
• Smoothies or Shakes – Add a couple tablespoons of the peanut butter powder to a blender with smoothie or shake ingredients and pulse to combine.
• Peanutty Drizzle – Mix 2 tablespoons of peanut butter powder with 1½ tablespoons of water. Drizzle over ice cream, oatmeal, brownies, parfaits, yogurt, or fresh strawberries.
• Ninja Creami Ice Cream – One of my favorite kitchen appliances is the Ninja Creami Ice Cream Maker. Stir a couple tablespoons of peanut butter powder into your favorite vanilla ice cream recipe to boost the flavor and protein!
• Peanut Butter Pancakes – Add to pancake batter to give your pancakes a peanut butter flavor. This pairs well with chocolate chips and sliced bananas.
• Protein Bars or Bites – These make a wonderful grab and go snack for busy days or mornings. Peanut butter powder is a great alternative to other protein sources when it comes to making protein bars.

How To Make Peanut Butter Banana Oatmeal

See the full recipe card with measurements and instructions below.

What You’ll Need

• Old-fashioned oats
• Water
• Peanut butter powder (such as PBFit)
• Vanilla
• Cinnamon
• Soy milk (or other high-protein plant-based milk)
• Banana
• Chopped peanuts

How to Make this Recipe

1. Combine the oats and water in a saucepan. Bring to a low simmer for 5-7 minutes or until it thickens and becomes creamy. (Microwave instructions: Heat in a microwave-safe dish for about 2-3 minutes, checking to make sure it doesn’t boil over.)

2. Remove the pan from the heat and stir in the peanut butter powder, vanilla, cinnamon, and soy milk. Mix in the mashed banana.

3. Spoon the oatmeal into a bowl and top with chopped peanuts. For extra sweetness, add a tsp of stevia or maple syrup. (Other topping ideas: sliced bananas, chocolate nibs, or granola.)

Notes & Storage

Storage: If you double or triple the recipe, leftover oatmeal can be stored in an airtight container in the refrigerator for up to 4 days. Reheat it on the stove or in the microwave with a splash of water or plant-based milk to loosen it up.

Notes:

• Milk Options: We use soy milk in a lot of our recipes because of its protein content, but feel free to use any plant-based milk you like. Just keep in mind that using a lower-protein milk will reduce the total protein in the recipe. If you’re avoiding soy, pea milk is another higher-protein option.
• Topping Ideas: Other topping ideas that would complement this oatmeal are chocolate chips or cacao nibs, chopped walnuts or pecans, pumpkin seeds, granola, a drizzle of melted chocolate or peanut butter, fresh sliced bananas or strawberries, a drizzle of maple syrup, and shaved coconut flakes.
• Cooking Times: Because different brands of oats have slight variations in size and texture, some brands may cook faster than others. Always watch the oats to ensure they do not overcook or accidentally boil over. Add more time as needed until a creamy consistency is reached.
• Sweeten Naturally: A ripe banana (showing some brown flecks) will lend a natural sweetness to this oatmeal. However, if you’d like it to be sweeter, you can add a drizzle of maple syrup, a bit of stevia, or a teaspoon of coconut sugar.
