I started with my traditional chocolate cake recipe (yes, I've been using that a lot lately). You could use any cake/cupcake recipe or just boxed cake mix (if you must). Instead of cupcake liners I used sugar cones.
To secure cones I used an upside down aluminum lasagna pan with holes cut out. I baked them for about 20-25 minutes. Once done I allowed cupcakes to cool.
I frosted with my usual Magnolia Buttercream Frosting Recipe using a star tip. I added sprinkles for decoration.
