Variation of Ankit R Gadiya's answer. The inner for loop was displaying the html code. I needed to de-indent it to get it to properly render the markup. I also added the post's excerpt:

{% assign postsByYear = site.posts | group_by_exp:"post", "post.date | date: '%Y'" %}
{% for year in postsByYear %}
  
{{ year.name }}
  {% assign postsByMonth = year.items | group_by_exp:"post", "post.date | date: '%B'" %}

{% for month in postsByMonth %}
{{ month.name }}

  {% for post in month.items %}
    

      {{ post.title }}
      
{{ post.excerpt }}
    
  {% endfor %}


{% endfor %}
{% endfor %}
