The only way you can do that is by opening ../post-templates/content.php
and replacing:
<a href="<?php echo esc_url( get_permalink() ); ?>" rel="nofollow" title="<?php _e( 'Read More...', 'acosmin' ) ?>"><i class="fa fa-ellipsis-h fa-lg"></i></a>
with:
<a href="<?php echo esc_url( get_permalink() ); ?>" rel="nofollow" title="<?php _e( 'Read More...', 'acosmin' ) ?>">Read More</a>
Also open style.css
find these lines:
.post-template-1 .details .post-small-button a {
display: block;
width: 48px;
height: 100%;
}
replace with:
.post-template-1 .details .post-small-button a {
display: block;
height: 100%;
}
and:
.post-template-1 .details .post-small-button {
width: 48px;
text-align: center;
border-width: 1px;
border-style: solid;
font-size: 11px;
-webkit-box-shadow: 0 2px 0 rgba(225,225,225,0.5);
-moz-box-shadow: 0 2px 0 rgba(225,225,225,0.5);
box-shadow: 0 2px 0 rgba(225,225,225,0.5);
}
with:
.post-template-1 .details .post-small-button {
text-align: center;
padding: 0 20px;
border-width: 1px;
border-style: solid;
font-size: 14px;
-webkit-box-shadow: 0 2px 0 rgba(225,225,225,0.5);
-moz-box-shadow: 0 2px 0 rgba(225,225,225,0.5);
box-shadow: 0 2px 0 rgba(225,225,225,0.5);
}
