Outside of novelty stuff for Bachelorette party, you don't find all that many edible items looking like a penis. If you are ever in Taiwan or maybe NYC during April, you'll be able to try some of the following foods.
In the heart of the Ximending area in Taipei, you'll see the following sign with the caption "a piece of Gayke". This is where you will find a waffle stand making delicious penis shaped waffles stuffed with sausage and cheese filling inside.

At 18 cm (about 7 inches) it's quite a mouthful.

If one 7 incher isn't enough for you, you can always get a two pack.
