I have shared many waffle recipes with you over the years, like my Dairy-Free Waffles, Gluten-Free Waffles, or classic Liege Waffles, but that’s the first time I made such easy, healthy waffles. They are perfect for meal-prepping a week of healthy breakfasts.

It takes under 20 minutes to make a batch of these healthy waffles. Plus, they can be stored in the refrigerator for four days or frozen for up to a month.

Protein waffles are classic waffles made with added protein powder. They are a healthy recipe packed with proteins, low calories, and low fat, perfect for keeping you full in the morning or refueling muscles after a workout.

Ingredients and Substitutions

All you need to make high-protein waffles are:

• Eggs – Make sure you use large eggs to keep the waffles moist and not dry.
• Egg White – These add protein and crispy edges to the waffles.
• Plain Greek Yogurt – Yogurt brings even more proteins and keeps the waffle fluffy.
• Plant-Based Protein Powder – Always measure the protein powder in a measuring cup, not with the scoop provided in the box. Not all brands have the same scoop volume, leading to different textures in baked goods.
• Crystal Sweetener – Use your favorite crystal sweetener such as coconut sugar or any granulated sweetener like allulose.
• Baking Powder – for an airy crumb.
• Old-Fashioned Rolled Oats – This turns into oat flour in the blender and binds the waffle batter. Oats are high in fiber and vitamins like vitamin E, folate, and iron, and super healthy whole food to add to these waffles.
• Avocado Oil – You can also use melted coconut oil or melted ghee.
• Almond Milk or any non-dairy milk you love, including oat milk or soy milk, for an extra protein boost.

How To Make Protein Oat Waffles

These are blender waffles that are easy to make in 5 minutes in a high-speed blender or small smoothie blender.

1. Pour all ingredients into the jug of a smoothie blender. Adding the liquid ingredients first matters for a narrow blender like my NutriBullet. For large high-speed blenders like Vitamix, the order doesn’t matter much.
2. Blend on the high-speed setting, stopping a few times to scrape down the sides of the jug, if indeed.
3. The batter should be fairly liquid with no lumps of oats.
4. Set the batter aside in a medium bowl for at least 10 minutes.
5. During this time, the fiber from the oats and protein from the protein powder absorbs the liquid and thickens the batter.
6. Warm the waffle maker at a high temperature, then use a cooking spray to oil the waffle plates evenly.
7. Pour about 1/2 cup of waffle batter – more or less depending on the size of the iron plate.
8. Close the waffle iron and cook the waffles for 3 minutes, then open and check the texture and color. The waffles are ready when golden brown and crispy on the edges but still moist in the center. Don’t overbake the protein waffles, as they quickly turn dry.
9. Then regrease the plate and cook the remaining batter.

Flavor Variations

You can use this protein waffle recipe and play with flavors by adding or swapping some of the below ingredients:

• Stir 1/4 cup of your favorite chocolate chips in the batter.
• Use chocolate protein powder for cocoa-flavored waffles.
• Add 1/4 teaspoon of vanilla extract. Watch out! Some protein powders have a strong vanilla flavor, so don’t add too much extract or the vanilla flavor is overpowering.

Storage & Meal Prep

These waffles can be stored for up to 4 or 5 days in an airtight container in the refrigerator. I also like to make a triple batch of them and freeze the waffles individually in zip-lock bags. They are truly the perfect freezer-friendly breakfast for busy mornings on a healthy lifestyle.

The day before, I pop the waffles on the kitchen counter, and they are ready for breakfast the next day. There are a few ways you can rewarm waffles, depending on the texture you are after.

I have many options for rewarming the waffles:

• Microwave – This is not my favorite option, but this softens the waffles and warms them up in less than 30 seconds.
• Toaster Oven or oven set on 300°F (150°C). Bake them on a tray for a few minutes until crispy.
• Bread Toaster – Pop the waffles in the toaster as if the waffle was a slice of bread. This makes the waffles ultra-crispy.
• Air-Fryer Waffles are great, but they dry out quickly! Rewarm them for only 1 minute at 350°F (180°C).

Allergy Swaps

I listed below some substitution ideas to use if you are allergic to some of the ingredients.

• Dairy-Free – You can use any yogurt in this recipe, plain soy yogurt, or plain oat yogurt are great dairy-free options.
• Egg-Free – I didn’t try using egg replacers in this recipe yet, and I am not sure they would work without changing the ratio of oats.
• Gluten-Free – Pick gluten-free oats and gluten-free baking powder.
