Place the flour and psyllium husks in a bowl, then add the water and the melted peanut butter.

Mix the ingredients together until well combined, then let the mixture rest briefly until it firms up. Shape the mixture as desired on a baking tray and place it in the oven at a high temperature.

Once it is set and firm, remove it and serve. It is best to let it cool and then place it in the refrigerator for a few minutes to firm up further. Enjoy!
