In a mixing bowl add softened cream cheese beat until light and smooth for a minute using an electric beater.
Add heavy cream, butter, cocoa powder, powdered erythritol and vanilla and beat again for 1-2 minutes until creamy batter is formed.
Cover and place the bowl into the freeze for 10 minutes until the batter firms up a little.
Meanwhile, shave some chocolate from any chocolate bar and keep it ready on a plate.
Scoop out the cream cheese batter and place it on a parchment paper. Then roll them over the chocolate shavings until uniformly coated. Repeat the same with the remaining chocolate cream cheese batter.
Place the fat bombs into the fridge to harden (5-10 minutes) and serve later.
