I think this is a pretty good representation of rams in pastry form. I can see the phallic resemblance, but honestly, I think this isn’t bad at all. If you wanted to be sure they wouldn’t be confused with anything other than a ram, perhaps you could get some food-grade paints and paint in eyes, nose, mouth, nostrils, etc. I think the faces being painted/frosted on would help eliminate the tendency to see a dick and make it less ambiguous.
