Luego crea una nueva entrada o una nueva página y ahí pega esto:

<script src="http://nombre-de-mi-blog.blogspot.com/feeds/posts/default?max-results=9999&alt=json-in-script&callback=loadtoc"></script>

Cambia la URL de tu blog donde se indica y listo.

Así de fácil podrás tener un sitemap en tu blog. El índice de los post se ordena alfabéticamente y se actualiza de modo automático cada vez que publicas una nueva entrada.
