How can I render html tags in an express and ejs blogging application?

I am working on a blogging application with Express, EJS and MongoDB.

In my posts.js controller I have:

exports.getSinglePost = (req, res) => {
    let id = req.params.id;
    Post.findById(id, function(err, post){
        if(err){
            console.log('Error: ', err);
        } else {
            res.render('singlepost', {
                website_name: 'MEAN Blog',
                post: post
            });
        }
    });
};

The singlepost.ejs view has the code:

<header class="masthead" style="background-image: url('assets/images/home-bg.jpg')">
    <div class="overlay"></div>
    <div class="container">
      <div class="row">
        <div class="col-lg-8 col-md-10 mx-auto">
          <div class="site-heading">
            <h1><%= post.title %></h1>
            <span class="subheading"><%= post.short_description %></span>
          </div>
        </div>
      </div>
    </div>
  </header>

<div class="container">
    <div class="row">
        <div class="col-lg-8 col-md-10 mx-auto">
            <%= post.full_text %>
        </div>
    </div>
</div>

It works fine as long as the entry in the posts collection does not contain HTML tags:

{ "_id" : ObjectId("5e3063dbfa749d9229bab26f"), "title" : "Post One", "short_description" : "Lorem ipsum dolor sit amet.", "full_text" : "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."}

But when it does contain HTML tags:

{ "_id" : ObjectId("5e317594fa749d9229bab271"), "title" : "Post One", "short_description" : "Dolor sit amet.", "full_text" : "<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>"}

the singlepost view renders HTML in the browser:

<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>

In AngularJS the problem would be easely solved with ng-bind-html, but I'm not using AngularJS in this project.

So, how can I fix this bug in EJS?
