Access layout HTML in controller variable

HI,
In my cakephp 3 project I am using mandrill API to send email campaigns. So from a controller function I am creating the html section of the email and pass it to mandrill. Is there any way that I can access the html generating by a layout in controller function and to create the html to pass to the mandrill?

Thanks in advance,
Jipson
