Yeah, something like this.
My goto 'pancake' recipe is a variation:
Simple and tastes great! It should make 2-4 'buns' depending on how large your egg is and how much cream/etc. you add to it. I've found the coconut flour recipe is a bit finicky getting right.
I'd use something like these to get consistent shaped buns or if you can find the right shape/size a silicon baking mold to batch make the buns in the oven.
