In a large saucepan, bring the sugar, corn syrup, Earth Balance, & vanilla to a boil over high heat. Reduce the heat to medium & boil the mixture for 5 minutes, stirring occasionally. After 5 minutes, remove from heat.
Sift the powdered sugar, powdered soy milk, & salt into medium bowl. Add the powdered sugar mixture to pan & stir to combine. Let the mixture stand until slightly warm to touch, about 20 minutes.
Divide the dough into 3 equal pieces. Consider putting on rubber gloves, so you don't stain your hands. Add several drops of yellow food coloring to one piece of dough & knead food coloring into the dough until smooth and color is even. Repeat using red & yellow food coloring (for orange) with the second piece & leave the last piece white, but knead it until smooth. This isn't an easy task & could take up to 15 minutes!
Roll each piece into ropes of equal length (don't roll too thin or the dough will break) and push the three ropes together to form a long rectangle. Using sharp knife, cut the ropes into triangles. Some will be white tipped & some will be yellow tipped.
Shape the candy corn as desired! You can even make Mellowcreme Pumpkins! This yielded 110 candy corn, all larger than the store bought ones you're used to! You could easily half this recipe & have a ton to share with others. I made mine somewhat large, as they're easier to work with, but you could make smaller ones & have a TON!
