Thin Mint Cake


I’m the type of person when I’m told to do something…..I DO IT!

Earlier this month when we were in Branson, I saw a tweet about a thin mint cake, not just any thin mint cake, but ……. “the greatest cake I have ever made….EVER”

A cake that just screamed  “If you have ever enjoyed a thin mint you must try this thin mint cake recipe.  You must.

Ummmm, do I like thin mint? you betchya…….and so does my mom!

Friday was my mom’s birthday and she’s even a bigger fan of thin mints…… I knew this thin mint cake would be the perfect birthday surprise!

And boy did she LOVE her thin mint cake!

Almost as much as she enjoyed all the attention she got from her granddaughters!
