"Kitchen for Kids" However I am pretty certain you could make them with almost any cookie cutter style recipe. You want the dough to be dense, but other then that it should work.
To make the letters you basically roll the dough out into a snake then shape them in the letters you want. After they are cooked, you paint them with icing (icing sugar, gel icing color and a tiny bit of milk).
I thought this was a great idea and not only did C Monster get to do some baking, he also practised spelling his name.
