Prepare the cauliflower. Place it in a steamer and cook until they are soft.
Transfer the cooked cauliflower in a bowl and crush to make a puree. Use either fork or food processor to do this. Put in the erythritol and peanut butter into the bowl. Using a mixer, blend the ingredients together.
Toss in the grated coconut into the blended ingredients. Combine with a spatula until the mixture is completely blended.
Spoon some of the mixture onto your palm and shape into small balls. Spread more grated coconut on a flat plate and roll the balls onto it. Make about 20 or so balls. Keep them cooled in the fridge for one week.
