this can be done under theme files. We do not have an option to change this icon with text. So if you want to change this icon, you should play with functions/theme-shortcodes.php file where all muffin builder items and shortcodes are.
Sorry but in accordance to Item Support Policy, theme files customization are not included. So if you want to modify files, you must do this on your own. Or if you don't know how, please contact with your website developer.
