Preheat the oven according to the directions on your Funfetti cake mix box (usually 350°F).
Prepare the cake batter according to the package directions.
Place one cake cone into each cup of a standard muffin tin.
Fill each cone about halfway to two-thirds full with batter. Don't overfill. The batter rises while baking.
Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cupcakes to cool completely.
Pipe or spread vanilla frosting onto each cupcake to resemble a scoop of ice cream.
Top with rainbow sprinkles and an optional maraschino cherry.
Serve and enjoy!
