Cupcakes will be much easier to handle. To cut down on the mess, bake them in a flat bottomed ice cream cone.
Get the favored cake mix.
Prepare as directed on the box adding 1 cup of flour
Put ice cream cones into 9 X 13 cake pan and fill 2/3 full.
Bake according to package directions. May take a little longer than the standard cupcake because you can do 24 at a time.
When you ice them, be sure to cover any cake runs with icing (If there are any, it makes it look like melting ice cream.)
You can transport them in the same pan that you bake them in.
Extra tip. If you replace the 1/3 cup of oil in any boxed cake mix with 1 cup of mayonaise, it will be hard to tell that the cake is from a box and not from scratch.
