These Thin Mint Granola Bars are easy to make and perfect for breakfast or lunch boxes. Adding crushed chocolate cookies add another dimension of flavor to these sweet homemade granola bars.
I have a habit of buying cookies and hiding them under the cupboard. My family is pretty used to my sugar buying, so they know that most of the "extra" food is for the crazy baking that happens in our house.
So a package of store brand Thin Mints is definitely not just for eating. They know me a little too well for that. The first thing my daughter asked when she saw those cookies was, "what are you putting those in?".
She was right. They were definitely not for eating...at least not the traditional way.
Girl Scout cookies and treats tend to be all the rage in March. Now I have admitted before that I actually don't buy real GS cookies that often. (Don't hold me to that...because we do get them every once in a while.)
This year we happened to make it through the season without spending $5 for 3 cookies. I picked up some Keebler Grasshoppers because my mind was thinking through fun combos.
You see, I had this crazy thought. A few weeks ago I made Cookies and Cream Chocolate Chip Cookies that were super popular. It had me thinking up new creations with that flavor combo. Why not do mint cookies and cream this month?
I always use the base from these Caramel Oatmeal Bars when I make homemade baked granola bars. My kids go through granola bars like crazy, so we are always creating fun new flavors to share.
These bars come together so quickly and only take about 20 minutes to bake. Feel free to let them cool and eat them as is. They taste just as good that way too.
But this is me, and I have this crazy need to add more chocolate whenever I can. So, these bars got a healthy dose of chocolate and green drizzle. Hahaha!
Like how I said healthy and chocolate in the same sentence? Sorry. That made me giggle this morning...it's the little things.
Now my mind is running with about 10 other "cookie" granola bars, so I guess it's time to bake another batch.

Jocelyn Brubaker
Thank you so much Chris! 🙂
Elizabeth @ SugarHero.com
Hellooooo, sexy! I would flip if these showed up in my lunch. 🙂 And I laughed when you talked about your family, because mine's the same way. Anytime something "fun" comes home from the grocery store, they know that it's for the blog and not for them!
Jenn @ Deliciously Sprinkled
These look so good, mint and chocolate for breakfast is always a great way to start the day! I love how easy these bars are to make and I love the drizzle on top! 🙂

Ilona @ Ilona's Passion
Great recipe! I love different kinds of granola:)
Jocelyn Brubaker
Thanks Ilona! 🙂
Zainab @ Blahnik Baker
These bars look amazing!! Chocolate and mint is one of my favorite combinations and I always justify the $5 cookies in one serving 😮 I'm bad for myself.
Hayley @ The Domestic Rebel
Yeah, I usually can't justify spending $5 on a single serving size of cookies (come on, we all know the box is for one person!!) so I usually use the Keebler swap myself. I must make these granola bars; they look SO awesome!!
Jocelyn Brubaker
I totally agree the box is just for one person! 😉 Thanks Hayley!
Kelly
I LOVE Thin Mints. Any dessert recipe involving something with mint in the title is a must bake for me. I will definitely be giving these a try!
Jocelyn Brubaker
You will love these, I promise! 😉

With Thin Mints winning the title of America's favorite cookie this year, these granola bars are sure to be a hit! I can't wait to try these myself (Girl Scout mom here!)

I love that your daughter knows you so well. Squirrel now asks permission to eat food before digging in. I only buy Thin Mints once a year; the rest of the year I buy Keebler Grasshopper cookies when they go on sale. This here is one creative recipe. Love it! Pinned.
Jocelyn Brubaker
I love that she knows me so well too! 😉 Thanks Jennie!

Its good to know that Thin Mint addictions can be taken care of with Thin Mint knock offs year round! Even better, its good to know that delicious recipes like these granola bars can be made even when it isn't Girl Scout cookie season! Chewy-crunchy granola bars that taste like thin mints have to be delicious!
Jocelyn (Grandbaby Cakes)
These granola bars look so fantastic! Now I want some of this!

We each usually inhale one package of Thin Mints. Maybe if we double this year's order...because these have got to be made! I pinned the top picture.
