Having never lived in South Africa, where these amazing treats originated. I had to look up the meaning of Vetkoek and learned it means "fat cake" and is similar to a doughnut but is not made sweet.
Keep in mind, the coconut flour itself adds a little sweetness so it isn't as savory as dinner roll either.
Their texture is very tender and soft with a wonderful crunchy outside.
You can split these and serve them with savory fillings like chicken salad, tuna salad, egg salad or they are often served in Africa with a ground meat (mince) filling. They are also served spread with butter and honey or jam but for us following a low carb or keto diet use a zero carb syrup or low carb jam. I sprinkled the top of one of them with a zero carb. cinnamon "sugar" mixture. No matter how you eat these, they are amazing.
