Recent post on static html page (seo friendly )

Hello

i have setup a blog on my site https://www.rightcopywriter.com/blog
and i want my 5-10 recent blog post to be displayed on my site (static html) homepage in a seo friendly way so SE bots can read it and index it

I tried using BuzzBoost it works but I have found out that when you google text cached it doesn’t display the post

For eg

https://vandelaydesign.com/blog/tools/display-your-feed-on-a-static-html-page-using-feedburners-buzzboost/

homepage https://vandelaydesign.com/

Google cached
https://209.85.175.104/search?q=cache:https://vandelaydesign.com/&hl=en&rlz=1T4GGIH_enIN270IN270&strip=1

This is what google sees

I read somewhere about using rss2html but I have no clue how to setup that

Please help

Thanks
