These light and fluffy high-protein waffles are the perfect vessel for and sweet topping. Try mascarpone with berries or swap the mascarpone with whipped cream, sour cream or yogurt. It's almost like eating British scones (or biscuits if you're American) but in the form of waffles!

We're using cheese so technically these are chaffles (cheese waffles), although I made some modifications and added protein powder. If you don't have any whey protein powder, use powdered egg whites instead.

If you prefer your waffles savory rather than sweet, you can make these easy high-protein keto sandwich waffles instead.

Which Waffle Maker Should I Use?

Chaffles work best with a 4-inch Dash Mini Waffle Iron. It will only cost you about around $15 and it's perfect for mini waffles. Don't worry if you can't get a mini waffle maker — you can use a regular waffle maker — the only difference is the yield you'll get. Instead of 3 mini chaffles, you'll get 2 square Belgian chaffles, or 1 to 1 1/2 large round Belgian waffles.

Ingredients (makes 5 small waffles)

Protein waffles:
  • 1/2 cup mascarpone cheese (120 g/ 4.2 oz)
  • 5 large strawberries, sliced (90 g/ 3.2 oz)


  1. Preheat a mini waffle maker, or use a regular waffle maker. Sweet Keto Protein Waffles
  2. Place the egg white, mozzarella, protein powder (whey or egg white), baking powder and sweetener in a blender or a food processor. Process until smooth. Sweet Keto Protein Waffles
  3. To make 5 small waffles, spoon 2 tablespoons of the batter (about 31 g/ 1.1 oz) into the hot waffle maker. Close the waffle maker and cook for 3 to 4 minutes. Keep an eye on the batter in case it overflows.
  4. When done, open the lid and let it cool down for a few seconds. Use a spatula to gently transfer the waffle onto a cooling rack. Repeat for the remaining batter. Sweet Keto Protein Waffles
  5. Let the chaffles cool down completely. Sweet Keto Protein Waffles
  6. Spread the mascarpone (or use whipped cream) on top of each waffle and add sliced strawberries.
  7. Enjoy immediately or store the waffles, without any topping, in a sealed container at room temperature for up to 3 days, or in the fridge for up to a week. The container will keep them soft but you can leave them uncovered if you prefer them crispy. These waffles freeze well and can be kept in the freezer for up to 6 months. Sweet Keto Protein Waffles

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

I weighed and used isopure unflavored and my batter was super thick. There was not much liquid for all the dry ingredients. Only made about 7 T of batter so I divided into 5ths

Hi Lisa, I'm sorry about this, I had a typo in the unicode character and instead of 1/4 cup it showed 1/2 cup. The grams are correct but the cup size was wrong. I double check each ingredient every time but I missed this one. I hope the result was still good, even though the process was tricky!

Hmm. I actually weighed it so that wasn’t it. Is it possible the weight is wrong too?

If you went by weight (which I did too with all of the ingredients) and it was still too thick, I'm thinking it could be down to slightly different size of the egg. In my experience, large eggs can be anywhere between 50 and 65 grams, and similarly this may apply to egg whites (33 to 45 grams). If the mixture is too thick next time, I suggest adding a dash of egg white (I use carton egg whites for this purpose as I don't have to worry about storing the yolk). Another option would be to add a teaspoon or two of cream cheese or heavy whipping cream or almond milk.
