For me, chaffles are a game-changer. They’re great savory. Or sweet. And work well as bread or a bun. The basic recipe is 1 egg and 1/2 cup of shredded cheese, which would make two chaffles.

My Chaffle Tools
To make my chaffles consistently, I put the mini-waffle maker on my kitchen scale and then do:
- 10 grams of shredded cheese
- 25 grams of beaten egg (or batter)
- 10 grams of shredded cheese
The cheese on the top and the bottom helps to keep the chaffles firm and crispy. And no overflow of contents making a mess because I eyeballed the amount of filling incorrectly. Oh, and don’t stack the chaffles if you make a number of them. It keeps the heat within them and makes them soft. I see some videos where they put them individually on a cooling rack. That helps the cheese crisp up as the chaffle cools.
The fun thing is watching the weight go down as the chaffle cooks, as water leaves as steam. When it hits 40 grams of weight, I know the chaffle is done. 
I bought this shaker bottle, so I can do a lot of eggs (or batter) at once, to store in the fridge so it’s ready to go. With my method of creating the chaffles, it’s much easier to dispense 25 grams of egg/batter out of that shaker cup.
I’ve tried a number of different recipes, but I keep coming back to the basic recipe above. It’s savory if I spread some Jalapeno cream cheese on it. Or sweet if I top it with SF maple syrup.
I typically use an Italian blend shredded cheese. But if I’m doing savory, I might go for a sharp cheddar.
An example of a sweet chaffle:
- 3 eggs
- 1.5 cups shredded cheese (I put in my Magic Bullet to make them like a flour)
- 2 tsp coconut flour
- 1 tsp vanilla
- 1/2 tsp cinnamon
- Liquid monkfruit sweetener
Whenever I make a batter for sweet chaffles, I always pulverize the shredded cheese into a powder. It mixes in the batter better, and the final product has a better texture. I need to spray the waffle iron if I don’t want a batter to stick, but don’t need to when I layer the shredded cheese top and bottom.
