Cupcake Or Muffin: What's the difference?

 Craving for cupcake make me gather some of the required ingredients such as:
2 cups of all purpose flour, 2 cups of pancake mix, 1 1/2 cup of sugar, shredded small size zucchini, 1 minced banana, 1 cup blueberries. In liquid form: 1 1/2 cup milk, 2 beaten eggs, I tbsp. vanilla, 1 cup canola oil or 1/2 cup butter (butter is optional)

After all the ingredients are mixed properly, the mixed ingredients are mold(ed) on required cupcake wraps (for the cupcake tray) and aluminum pan/plate. Bake on 350 degrees Celsius inside the oven for 40 minutes.

Here's the result.

Delicious of course!

Icing?

I don't like icing.
