Thin Mint Cookie Cake!!! Time to find some girl scouts

I’ve said it before but I’ll say it again, one of the reasons I’ve loved blogging so much (and probably why I’ve stuck with it for almost five years) is that I’ve made some great friends. Not only have I established relationships with people who live near me, but I also have wonderful friends spread out all over the country. Today we are celebrating my friend Madison! We’ve been virtual friends for years and I was lucky enough to meet her in person as well. In case you were wondering, she is just as sweet (and pretty!) in real life as she seems on the blog.

Thin Mint Cookie Cake

Madison’s shower is truly special because I know how badly she wanted a baby and she has been through so much along the way. We don’t know yet if she is having a boy or girl (it’s a secret), but I do know that baby will be LOVED. I’m just so happy for her and Joey. And Madison, from experience, it might be hard to believe, but being a mom is even better than you think it will be!

For Madison’s shower we are serving all things sweet (like her!) and of course I wanted to bring something rich and chocolatey. Plus, it’s Girl Scouts’ season and given the fact that we still had Thin Mints from last year (I cut myself off after I ate an entire sleeve in one sitting), I thought it was time I finally baked with them. This cookie cake was the perfect choice. It’s rich and fudgy (almost brownie like) with crunchy chunks of Thin Mints throughout. Oh yeah, and the Thin Mint buttercream is something to get excited about as well. The extra frosting in my freezer is calling my name…

Thin Mint Cookie Cake!!! omg!!
