Cake biscuits

Found these in the kitchen at work, accompanied by the following letter:

Cakes!! (well sort of... they are more like biscuits).
My 5 year old nephew "Harry" made these for "Uncle Charlie and all the people that work with him at the mill"

They aren't great but nor are they terrible / poisonous. So if you're bored at all today + fancy a culinary adventure, look no further.

Signed Charlie.

I did not partake in the cake biscuits but someone did as they were all gone by the end of the day.
