Low-Carb Banana Nut Chaffles Recipe


You probably all know by now that bananas are not keto. Each banana contains a staggering 31 grams of carbohydrates! But no worries, this banana chaffle does not have that particular problem!

Personally, i find “Banana Nut” anything simply delicious! Bringing this flavor in a chaffle, definitely brings back memories of the banana bread my mom used to bake when I was a child. The sweet, flavorful banana combined with the delicious taste and crunch of walnuts, served warm with a generous pat of melted butter… there’s just nothing better!

So the assignment for me for this recipie was to make sure that this keto banana nut chaffle embodies all of nostalgia. And, I think we did just that! These chaffles are easy to make with a few simple keto ingredients. They come together in just a few minutes, and are perfect when that banana-nut combo craving hits.

Oh! and a bonus hint- We highly recommend savoring this chaffle while it’s still warm, generously adorned with butter. You’ll be delighted that you did!

So, without further ado let get right into it shall we?

Must Haves For Keto Banana Nut Chaffles

Heavy Whipping Cream

This isn’t just for the whip! The full-fat whipped cream gives a creamy and rich taste to our keto banana chaffle that you wouldn’t achieve with milk or other alternatives. Plus, it’s low in carbs, making it perfect in keto.

Lakanto Powdered Sweetener

Ditching the sugar doesn’t mean ditching the sweet. The Lakanto Powdered sweetener is a favorite of mine because it doesn’t leave a weird aftertaste. It’s also a great sugar substitute for keto recipes.

Coconut Flour

Unlike almond flour or regular flour, coconut flour is more absorbent and gives a slightly sweet, airy texture to our banana nut chaffles. It’s also keto-friendly, so we can savor without guilt. If you’re out, almond flour is a great substitute, but it might slightly change the texture.

Egg, Large: Eggs are the binding ingredient in our banana nut chaffles. They provide structure and provides good fats and protein.

Vanilla Extract

This adds depth and warmth. This brings in a gentle aroma that pairs excellently with our banana flavoring. It’s subtle but makes all the difference in our dessert chaffle recipes.

Banana Extract

Want that strong banana taste without the high carbs from actual bananas? Banana extract is the key! It’s like infusing the soul of a banana into our chaffles without straying from keto.

Walnuts (chopped)

These provide a crunchy contrast to our soft chaffles. Besides, who can resist the classic combination of banana nuts? Feel free to swap with other nuts if you prefer.

Optional – ChocZero Sugar-Free Maple Syrup

Perfect if you fancy a drizzle of sweetness without the sugar rush. It’s like the icing on our keto cake, or in this case, chaffle!

Warm Up Your Waffle Maker.
Preheat your mini waffle maker. Preheat your mini waffle maker. Doing this first ensures it's hot and ready, giving our banana chaffles that perfect golden brown finish.
Make The Batter.
In a medium bowl, combine all the chaffle ingredients except the walnuts. You'll want to whip or blend on high until the batter is smooth. The consistency makes an even distribution of that delicious banana flavoring.
Fold The Walnuts.
Now, gently fold the walnuts into the batter. It's all about the crunch in every bite!
Cook For 2-4 Minutes.
Once evenly mixed, pour the batter into your mini waffle iron batch by batch. Allow the batter to cook in the waffle maker for 2-4 minutes. You're looking for that lovely golden brown color to know they're done just right.
Garnish and Serve.
Here's where you can get fancy. Garnish with sugar-free maple syrup and sprinkle a few more chopped walnuts for extra crunch. 



  • Mini Waffle Iron: The key to creating perfectly-sized chaffles. The mini waffle maker ensures they cook evenly and are the ideal size for stacking or eating on the go. It also gives those adorable waffle patterns we all love.
  • Medium Bowl: Used for mixing the ingredients. It's large enough to hold everything without overflowing when you mix.
  • Blender or Whip: Essential for ensuring a smooth batter consistency.


  • Pre-mixing your dry ingredients can speed up the process. Combine coconut flour, Lakanto sweetener, and any other dry ingredients in a jar. This way, you're ready for chaffle action anytime!
  • Always make sure your waffle iron is hot before you pour the batter. A hot iron seals the batter instantly, resulting in crispy edges.
  • Remember, with this batter, less is more. Don't overfill your mini waffle maker, as it can cause it to spill.


  • If you happen to have any banana chaffle leftovers (they're so good, it's rare!), let them cool completely. Once cooled, store in a tight container in the fridge. The banana chaffles can stay fresh for up to 3-4 days.
  • If you want to freeze them for later, place a piece of parchment paper between each chaffle to prevent sticking. Or, place them in a ziplock bag. They should last for up to 6 months.
  • When you're ready to eat, reheat in a toaster, microwave, or oven for 30-60 seconds.

Serving Suggestions

  • While delicious on their own, try serving your banana nut chaffles with a dollop of cream cheese or butter for added richness.
  • Pair your chaffles with keto-friendly berries, bacon, or even a smoothie to make for a delightful and filling breakfast. Then, a cup of unsweetened coffee or tea, and you're good to go!
  • For dessert chaffle recipes, consider adding a scoop of sugar-free whipped cream on top.

Frequently Asked Questions

Why use Banana Extract instead of real bananas?

While real bananas are delicious, they’re high in carbs and a big NO in keto. Using banana extract gives the chaffle a rich banana flavor without the added carbs, making it perfect for those following a strict keto diet.

How do I know when my chaffles are done?

Cooking for 2-4 minutes usually gets the job done. The chaffles should have a golden-brown hue and a slightly crisp exterior. If in doubt, it’s always safer to cook a bit longer on a lower setting to avoid burning.

Can I omit the walnuts?

If you’re not a fan of walnuts or have an allergy, you can leave them out.
