My 4-year-old loves pancakes and waffles and I’m always looking for ways to add some extra protein to his meals, so these banana oat waffles are one of my favorite breakfast recipes! These waffles are packed with protein and fiber. Quick to prepare and perfect for a hearty morning meal, this recipe is easy to whip up in a blender, giving you fluffy, golden waffles every time.

Benefits of Peanut Butter and Bananas

Peanut butter and bananas are a classic combo for good reason. Bananas are a great source of potassium, natural sugars, and energy, while peanut butter adds protein and healthy fats. Together, they create a balanced and delicious meal that keeps you fueled throughout the morning. Plus, the oats in this recipe add fiber to keep you full and support your digestive health.

Ingredients & Substitutions

  • Old-Fashioned Oats – These add fiber and nutrients to the recipe. You can substitute quick oats, but avoid steel-cut oats as they won’t blend well.
  • All-Purpose Flour – This ingredient provides structure to the waffles. For a gluten-free version, you can use a gluten-free flour blend.
  • Baking Powder – Baking powder helps the waffles rise and gives them a fluffy texture.
  • Bananas – You should use ripe bananas for natural sweetness. Overripe bananas work best.
  • Avocado Oil – This adds moisture to the batter. You can substitute it with melted coconut oil or vegetable oil, if you prefer.
  • Peanut Butter – Choose creamy peanut butter for the smoothest batter — or you can use almond butter or sunflower seed butter as alternatives.
  • Vanilla Yogurt – Whole milk yogurt adds richness and flavor, but Greek yogurt or plain yogurt with a splash of vanilla extract also works well.
  • Eggs – Eggs bind the batter and add structure to the waffles.
  • Milk – You can use any milk you like, whether dairy or non-dairy options such as almond or oat milk.

Making Waffles with Oats

Using oats in place of traditional flour is a great way to boost the nutrition of your waffles. Oats are packed with fiber and nutrients, making these waffles a wholesome breakfast option. Blending the oats into a smooth batter creates the perfect texture, similar to using oat flour, while keeping the recipe simple and gluten-free (if using certified gluten-free oats).

How to Make Peanut Butter Banana Oat Waffles

Add all the ingredients to a blender and blend until smooth.
Use a spatula to scrape down the sides of the blender as needed.
Pour ½ to 1 cup of batter (depending on your waffle iron’s size) onto the preheated, greased waffle iron.
Close the lid and cook until golden brown on both sides.
Carefully remove the waffle and place it on a wire cooling rack to prevent fogginess.

How Much Batter to Use in a Waffle Maker

The amount of batter to pour into your waffle maker will depend on its size and shape. Most standard-size Belgian waffle makers (like the one in the photos) will take about 1/2 cup of batter per batch. The larger square type of waffle makers (that make 4 4-inch waffles) will take about 2/3 cup of batter. This recipe should make 4-5 large Belgian waffles or 12-16 (4-inch) square waffles, but it will depend on the thickness and size of your waffle maker.

How to Store Leftover Waffles

To store leftover waffles, allow them to cool completely before placing them in an airtight container in the refrigerator, where they can be kept for up to four days. For longer storage, freeze the waffles by stacking them with parchment paper between each one to prevent sticking, then seal them in a freezer bag or airtight container for up to two months. When you’re ready to enjoy the leftovers, reheat the waffles in a toaster, oven, or air fryer to ensure they stay crispy and fresh.

Description

These banana oat waffles are easy to make and packed with protein! These waffles are the perfect family-friendly breakfast!

Ingredients

Units Scale
  • 2 cups old-fashioned oats
  • 1 1/2 cups all-purpose flour
  • 1 tablespoon baking powder
  • 2 medium bananas, very ripe
  • 1/4 cup avocado oil
  • 1/2 cup creamy peanut butter
  • 1/2 cup whole milk vanilla yogurt
  • 2 eggs
  • 1 3/4 cups milk (I used skim but any milk is fine)
  • Pinch of salt

Note: Make sure your bananas are very ripe! If not, add 1-2 tablespoons of granulated sugar for added sweetness.

Instructions

  1. Spray a large waffle iron with non-stick cooking spray and turn it on to preheat while you prepare the waffle batter.
  2. Add all the ingredients to a blender and blend until smooth. With the blender turned off, scrape down the sides of the blender with a rubber spatula and blend again to ensure all the ingredients are incorporated.
  3. Depending on the exact size of your waffle iron, pour approximately ½-1 cup of batter onto the preheated waffle iron, close the lid, and cook the waffle until it is golden brown on both sides.
  4. Carefully lift the waffle off the waffle iron and place it on a wire cooling rack.
  5. Repeat steps 3 and 4 until all the batter is used up.

  6. Serve the waffles warm, drizzled with maple syrup, and topped with banana slices if desired.
