When the chaffles craze started, I got my Dash mini waffle maker from Amazon for $6.99. Looks like Amazon has them now for $7.99.
My process for "bread"/buns is below. But if I'm making a sweet application, I usually make a batter. First thing I do then is to run whatever shredded cheese I use into a powder with my Magic Bullet, to make it easier to mix everything up. Including with other powders.
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.

The Serious Keto YouTube channel has many videos with chaffle variations
To make my chaffles consistently, I put the mini-waffle maker on my kitchen scale and then do:
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. :)
