Show the date at the end of the post

I want show the date (last updated date or published date) at the end of the post, not below the title.

Thanks to some other support topics I was already able to style the date with additional CSS

/* Display updated date */
.posted-on .updated {
    display: inline-block;
    margin-right: 1em;
}

.posted-on .updated + .entry-date {
    display: none;
}
/*Add date prefixes */
.posted-on .updated:before {
    content: 'Zuletzt aktualisiert am ';
}
.posted-on .entry-date:before {
    content: 'Zuletzt aktualisiert am  ';
}

Now I want to show this at the end of the post. How can I do that? Under Layout > Blog > Single I can only click show or not show.
