How to Make Crispy Sweet Potato Protein Waffles
What if I told you that the sweet, crispy waffles you love for breakfast had roots back to the Middle Ages? That’s right—waffles originated in Europe, particularly in France and Belgium, as a savory dish often made with cheese and herbs. Over time, they evolved with the addition of leavening agents and sweeteners, becoming the golden, gridded treats we know today.
Now, let’s talk sweet potatoes—a superfood packed with fiber, vitamins, and natural sweetness. When mashed and mixed into a waffle batter, they add richness, moisture, and a light natural sugar that caramelizes beautifully in the waffle iron. And when you toss in protein powder? You’ve got yourself a Crispy Sweet Potato Protein Waffle—the perfect powerhouse breakfast that’s both nourishing and insanely satisfying. With that, let's dive into waffle heaven!
How to Make Crispy Sweet Potato Protein Waffles
Prep Time: 2 minutes | Cook Time: 15 minutes
Servings: 4 medium round waffles

Ingredients
-
- 1 cup mashed sweet potato (pre-cooked and cooled)
- ¼ cup almond milk (or any milk of your choice)
- 2 eggs
- ⅓ cup whole wheat flour
- ¼ cup unflavored protein powder
- ¼ cup vanilla protein powder (about 22g)
- 3 tsp baking powder (or 1 tsp baking soda)
- 2 tsp cinnamon
- ¼ tsp nutmeg
- Cooking oil spray (for greasing your waffle iron)
Instructions
Step 1: Whisk the Wet Ingredients
In a mixing bowl, whisk together the mashed sweet potato, almond milk, and eggs until smooth.
Step 2: Combine the Dry Ingredients
In a separate mixing bowl, mix the whole wheat flour, unflavored protein powder, vanilla protein powder, cinnamon, nutmeg, and baking powder.
Step 3: Fold Wet Into Dry
Gently fold the wet mixture into the dry using a silicone spatula. Do not over-mix—your batter should be thick with small lumps.
Step 4: Heat the Waffle Iron
Preheat your waffle iron and spray generously with cooking oil spray to prevent sticking.
Step 5: Cook the Waffles
Using a ladle spoon, scoop out about ⅓ cup batter and drop it in the center of your waffle iron. No need to spread—it will naturally expand. Close and cook for exactly 3½ minutes for crisp perfection.
Step 6: Repeat & Serve
Grease between each waffle and repeat. Serve warm with your favorite toppings like Greek yogurt, almond butter, or fresh berries.
Tips to Make Fluffy but Crispy Sweet Potato Waffles
- Use an immersion blender or food processor to mix your sweet potato, eggs, and milk for a super-smooth base.
- Don’t over-mix the batter—overworking the flour will make dense waffles.
- Always grease your waffle iron between batches to prevent sticking.
- Scoop the batter into the center and let it spread naturally.
- Let the waffle cook for the full 3½ minutes—any less and it might stick or fall apart.

Sweet potatoes are rich in fiber, vitamin A, and potassium, promoting gut and eye health. Protein powder helps with muscle recovery, satiety, and energy balance, while eggs provide complete protein and healthy fats. Whole wheat flour adds even more fiber to keep you feeling full longer. Unlike traditional waffles that often lead to a mid-morning crash, this version offers lasting energy thanks to clean ingredients and no refined sugars. Each serving (1 medium waffle) comes in at approximately 180 calories, with 12g of protein, 20g of carbs, and 6g of fat, making them perfect for meal prep, post-workout fuel, or a wholesome kid-friendly breakfast.

Frequently Asked Questions About Sweet Potato Protein Waffles
Can I use canned sweet potatoes instead of fresh ones?
Yes, you can! Just make sure they are unsweetened and drained thoroughly. Canned sweet potatoes work well if you're in a rush, but for the best texture and flavor, roasting fresh sweet potatoes is ideal. Simply roast, peel, and mash before measuring. Avoid any added syrup or seasonings found in some canned varieties, as it can throw off the balance of the recipe. If using canned, you might want to reduce the almond milk slightly since canned sweet potato tends to be a bit wetter than freshly mashed.
Can I make these waffles dairy-free?
Absolutely. This recipe is already mostly dairy-free thanks to almond milk, but double-check your protein powder—some contain whey or milk derivatives. Swap in a plant-based protein powder like pea, brown rice, or hemp to keep things 100% dairy-free. Also, make sure to grease your waffle iron with a dairy-free cooking spray like avocado oil or coconut oil.
What can I use instead of protein powder?
If you don’t have protein powder, you can substitute it with more whole wheat flour or oat flour. The texture will be a little different, and the protein content will drop, but they’ll still be delicious. You can also try Greek yogurt or chia seeds mixed with the batter to bump up the protein naturally. Just keep in mind that any change in dry ingredients may affect the moisture level, so adjust your almond milk accordingly.
How do I store and reheat leftover waffles?
These waffles store beautifully! Let them cool completely, then place in an airtight container or zip-top bag and refrigerate for up to 4 days. For longer storage, freeze them in layers with parchment paper in between. To reheat, pop them in a toaster or toaster oven for a few minutes. This keeps them crisp on the outside. Avoid microwaving unless you're okay with a softer waffle. They're great for grab-and-go weekday breakfasts!
Can I make the batter ahead of time?
You can, but it’s best to cook the waffles immediately after mixing for the fluffiest results. If you do need to prep ahead, store the wet and dry ingredients separately, then combine right before cooking. This prevents the baking powder from losing its leavening power. If you mix the full batter ahead of time, keep it in the fridge in an airtight container for up to 24 hours. Stir gently before using to redistribute the ingredients.
Can I make these gluten-free?
Yes, making these gluten-free is easy! Just replace the whole wheat flour with a 1:1 gluten-free flour blend or oat flour. Be sure your protein powder is also gluten-free, as some may contain traces of wheat.
What toppings go best with sweet potato protein waffles?
The possibilities are endless! For a protein-packed breakfast, top your waffles with Greek yogurt and a drizzle of almond butter. For something sweeter, try fresh berries, chopped pecans, and a splash of maple syrup. You can also go savory with a fried egg and avocado on top.
