This works for me (Twig 1.x):

final class UtilTwig
{
    /**
     * @param string $pathAbsTwig
     * @param array $vars
     * @return string
     * @throws \Twig\Error\LoaderError
     * @throws \Twig\Error\RuntimeError
     * @throws \Twig\Error\SyntaxError
     */
    public static function renderTemplate(string $pathAbsTwig, array $vars)
    {
        $loader = new Twig_Loader_Filesystem([''], '/');
        $twig = new Twig_Environment($loader);
        $template = $twig->loadTemplate($pathAbsTwig);
        $mailBodyHtml = $template->render($vars);

        return $mailBodyHtml;
    }
}

Usage:

$htmlBody = UtilTwig::renderTemplate('/absolute/path/to/template.html.twig', [
    'some' => 'var', 
    'foo' => 'bar'
]);
