Dissolve bouillon in water, then stir the marmite in until dissolved

Whisk egg into the bouillon/marmite mix

Measure out flour and add the grated parmesan cheese

Mix wet and dry ingredients together into a dough

Roll dough out onto a floured surface and cut into desired shapes. I used a cute bone shaped cookie cutter which was 3D printed for me by the lovely Ronel Pieterse from All Sorts 3D Prints

Bake for 30 mins at 150 degrees.

Allow to cool before treating your dog!
