Preheat the oven to 350 degrees.
Prepare a muffin tin with paper liners and set aside.
Prepare the cake mix according to the package directions.
Fill the cupcake liners ¾ full. Bake for 13-15 minutes or until the internal temperature reaches 200-209 degrees. Remove the cupcakes and let them cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Fill a piping bag with the frosting. Cut off the tip.
Hold the cupcake in one hand, and using the other hand, cover the frosting with the crunch while shaping it into a dome. Continue until all cupcakes are done. Enjoy!
