Preheat the oven to 175 °C/ 350 °F.
Line a loaf pan with parchment paper: Simply cut two strips of paper - one should be the width of the sides and one the width of the ends.
Make both strips long enough so that they hang over the edges and then place them in a loaf pan.
The strips of parchment will be used to lift the bread from the pan.
You can make the paper stick to the pan by lightly greasing the pan with ghee.
I used a 20 x 12 cm / 8 x 5 inch loaf pan.
Place the whole eggs and the egg whites into a bowl and mix using a fork.
Set aside for later.
The reason you shouldn't use only whole eggs is that the buns wouldn't rise with so many egg yolks in.
Don't waste the egg yolks - use them for making Home-made Mayo, Easy Hollandaise Sauce, Frozen Fat Bomb, Smoothies, Keto Coffee or Lemon Curd.
Place all the dry ingredients in a bowl and mix well.
Make sure the dry ingredients are well combined to avoid uneven results.
Add the egg mixture and process well using a mixer until the dough is thick.
Add boiling water and process until well combined.
Do not use whole psyllium husks - if you cannot find psyllium husk powder, use a blender or coffee grinder and process until fine.
If you get already prepared psyllium husk powder, remember to weigh it before adding to the recipe.
I used whole psyllium husks which I grinded myself.
Do not use just measure cups - different products have different weights per cup! Place the dough into a loaf pan lined with parchment paper.
Place in the oven and bake for 1 hour and 15 minutes (or up to 90 minutes).
When done, remove from the oven and place on a cooling rack.
Grab the sides of the parchment paper and place the bread on the cooling rack to avoid the bread from becoming moist on the sides.
Once the bread cools down, cut into 12 slices.
Keep as many slices as you need for the next 2-3 days.
Place the remaining slices in batches of two in freezer bags and freeze for up to 3 months.
When ready to be served, simply let the slices defrost or place in a toaster, oven or on a hot pan to crisp up.
Top with butter, cream cheese, sliced ham and cheese or home-made ham.
