Gather everything you need, including your favorite prebaked cupcakes.
Starting with clean, dry mustache candy molds, melt your yellow chocolate discs according to the package instructions.
Once melted, spoon your chocolate into your mustache candy mold and tap the mold on your counter or solid surface to remove any air bubbles.
Let your candies harden for about 1 hour before popping the candy from the mold.
Then repeat until you have enough chocolates for your cupcakes.
Prepare your orange icing by mixing food coloring into your white icing until you've reached the color you choose.
Once well mixed, add your orange icing to a piping bag or large plastic baggie. Snip the end of the bag to about 1/2 inch and frost your cupcakes in a circular motion.
Add the Lorax inspired mustache chocolate candies and serve.
