Oat flour is my go to flour and it has been for a while now.

I use it to make everything from cookies and muffins to pancakes and cornbread. And I've fine-tuned my recipes over the past few years in order to make the best use of this whole grain flour.

But somehow I hadn't published a recipe yet for waffles with oat flour.

I do have a recipe for oatmeal waffles which has been my family's favorite waffle recipe for years (and is the one on which I based this recipe).

But that recipe starts with rolled oats and is mixed in the blender- perfect if you don't have oat flour on hand.

However, if you don have oat flour, then these are the waffles for you.

Sweetened with just a touch of maple syrup and made entirely of whole grains, these oat flour waffles are unbelievably delicious. Fluffy with crisp edges, most taste-testers couldn't tell that they were actually made of quite wholesome ingredients!

Making Your Own Oat Flour

Although you can make your own oat flour by blending rolled oats, I highly recommend using store bought oat flour whenever possible for all of my recipes. When you grind your own oat flour, it can be very difficult to get it fine enough which affects how it absorbs liquid.

Some recipes, though, are a bit more forgiving of using homemade oat flour and waffles are one.

So if you decide to make your own oat flour for this recipe, you will need to blend ⅔ cup of rolled oats (~65 grams) to yield the amount of oat flour. Or just make these blender oatmeal waffles instead!

The Ingredients

• Oat Flour- Use certified gluten-free oat flour if needed. I like to use store-bought for most consistent results but you can use homemade if needed (or make these blender oatmeal waffles instead). I recommend using a kitchen scale but if you don't have one, use this method to measure- lightly pack into a measuring cup and then level off.
• Pure Maple Syrup- Maple syrup is the perfect compliment to the flavor of these waffles. However, you can use another sweetener of choice (see these maple syrup substitutes) or leave it out.
• Butter- Butter add wonderful flavor but for dairy free, this recipe works with melted coconut oil (which also adds a scrumptious, slightly coconut flavor) or avocado oil. *For best results, ensure all of the ingredients are at room temperature so that the butter doesn't re-solidify in the batter.
• Egg- You will need to separate the egg because we will whip the egg white separately in order to make the fluffiest waffles.
• Milk or Water- Water or any type of milk (dairy or dairy-free) works for this recipe.
• Baking Powder- This is a key ingredient for providing lift to the batter in order to create fluffy waffles.
• Sea Salt

The Method

1. Mix wet ingredients. In a large, microwave safe bowl, melt the butter. Mix in the maple syrup, water (or milk) and egg yolk (place the egg yolk in a separate bowl) until well combined. *Make sure the ingredients are at room temperature so that the butter doesn't solidify.

2. Add Dry Ingredients. Whisk the oat flour, salt and baking powder into the wet ingredients until just combined.

3. Whip the Egg Whites. In a medium bowl, use an electric mixer to whip the egg whites until stiff peaks form.

4. Fold together. Gently fold the egg whites into the batter until just combined.

5. Rest. Allow the batter to rest for 10 minutes in order to hydrate the oat flour (to ensure your pancakes are moist and fluffy). Preheat a waffle iron.

6. Cook. Generously grease or butter your waffle iron and scoop just enough batter to cover the iron. If anything, you are better to slightly underfill as overfilling will result in dense waffles. Cook until lightly crispy, about 4-5 minutes depending on your waffle maker.

7. Repeat. Repeat with remaining batter until all the waffles are cooked.

8. Serve!

Leftovers and Storage

To Store: Cool leftover oat flour waffles on a wire rack in a single layer and then store in an airtight container for up to 4 days or freeze for up to 3 months.

To Reheat: Reheat waffles in a toaster or toaster oven for 3-5 minutes until heated through or warm them in the microwave.

Make it Your Own

• Blueberry Waffles- After mixing the batter but before adding the egg whites, fold in ½ cup of frozen (no need to thaw) or fresh blueberries. (Or try some oat flour blueberry muffins instead).
• Cinnamon- Like in these blender oat waffles, add ¼ teaspoon of cinnamon for extra cozy flavor.
• Savory Waffles- Omit the maple syrup and vanilla. Top with savory breakfast toppings such as bacon, cheese, eggs, mushrooms and chives.

Tips for the Best Oat Flour Waffles

• Whip the Egg Whites- Taking the extra couple of minutes to whip the egg whites before adding them to the batter is a key step in order to ensure extra fluffy waffles every time.
• Don't Overfill Your Waffle Iron- If you overfill the iron, the batter has no where to go and you will end up with dense waffles. Instead, slightly under fill in order to give the batter room to puff up and get fluffy.
• Adequately Butter/Grease your Iron- Oat flour is more delicate than regular flour and so if it gets stuck to the iron, the waffles will kind of fall apart.
• Use Store-Bought Oat Flour (if possible)- In any recipe with oat flour (like these apple muffins), I recommend using store-bought as it has the most consistent results. It can be difficult to grind your own fine enough. If you only have rolled oats, make these blender oatmeal waffles instead
• Allow the Batter to Rest- After mixing, allow the batter to sit for 5-10 minutes to give the oat flour time to hydrate which is key for fluffy and tender waffles.
