Thin Mint Cake Bars Recipe
When Amanda and I got together in my kitchen, we created two incredible Girl Scout Cookie Cake Bars you are going to LOVE! I made mine with Thin Mint Cookies and Amanda made hers with the Peanut Butter Tagalongs. Both sooooo good! Take a look!

How to Make The Best Mint Cake Bars
Let’s start with the cake mix and buttah!
Amanda, my lovely egg cracking model at work 🙂
Mix it all up. I always end up using my hands. Much faster.
In pieces, add the dough to the bottom of your baking dish.
Press dough evenly, does not have to be perfect.
Add some chocolate chips.
Time for some Andes mint pieces. You can always use the whole Andes mints and cut them up if you can’t find the pieces.
Pour over your cake dough.
Ahhhh, time for the Gooey part of the bars 🙂
Love this part. Drizzle time.
Time for those fabulous Thin Mint Girl Scout Cookies. I broke mine into pieces.
Time to bake! Here are both of our bars, mmmm!
Let these babies cool, cut into bars and enjoy!

Have a great day! Come back soon!
Welcome to my online kitchen! Picky Palate is where you’ll find family friendly recipes along with the best Disney eats, tips and copycat recipes! 
Yum! Great way to move through the BOXES of girl scout cookies we have in our kitchen.
love thin mints! seriously our downfall 😉
we saw these on instagram and could not wait to see the recipe! you are so creative!!! love it!
YUM! Went to Brewsters tonight and they were OUT of Mint Chocolate Chip! I believe i’d rather have these! 🙂
These are incredible! What a clever idea. You have given me reason to grab a box of thin mints now! I can’t wait to try these fantastic looking bars.
I honestly believe all of my baked goods come out better when I use my hands to mix! And it is such a time saver. Love the look of these, thin mints have always been my favorite GS cookie!
How am I supposed to get anything done, when I know this recipe is out there? I’m going to be dreaming about this all afternoon! YUM!
You are too funny Jen!! Make the darn cake bars so you can get some work done 🙂
I just ran three miles…this is not good… *sigh*
Hey, at least you ran!!
Yes please, and thank you!
Hi Jenny!
These look great! Question: why did you top the bars with the cookies instead of putting them under the sweetened condensed milk (like you did with the Gooey Cookies & Cream Double Chocoalte Cake Bars)? By the ways, I’ve made those tons, and they are always a huge hit!
Thanks!
Taylor
Hi Taylor, I just wanted to be able to see the cookies on top for these, but you could certainly put them under the sweet milk if you’d rather 🙂 Hope you enjoy!!
I think i just gained ten pounds but I do not care. They look yummy!
I think our baking adventure was my favorite part of the weekend! 🙂 Can’t wait for our next creation!! xoxo
Me too, let’s get together again soon!!
These look scrumptious! My grandmother always used eagle brand milk (we call it that instead of sweetened condensed milk) in her desserts and they were always fantastic!
It’s the best!!! I find it hard to not eat it right out of the can with a spoon 🙂
I could not be more in love with these Jenny! Now to find another box of thin mints. This is brilliant!
Yah, that’s the trouble….keeping the box of thin mints around long enough to make them!
Oh yum! Now I wish I had bought some girl scout cookies at the grocery store yesterday. Serious regret over here.
We just got a box of thin mints from my sister. I can’t wait to try this out!
Woohoo! Hope you enjoy Liz!
Ohhhh yesssss!! Thin mints are my favorite ever!!
Mine too Lauren 🙂
these are straight up evil…and i love them!
I seriously need to find some Girl Scouts. I need my cookies so I can make these! 😀
I am super glad I am a cookie mom! 🙂 I will definitely have to buy another box to make these!! 🙂 Only problem is having all the extra cookies may end up adding extra pounds to my hips!!
Wow! Thin mints are my favorite. So these look delicious 🙂
oh my goodness! Jenny these look wonderful… and SO very easy w/ the cake mix. i have leftover andes mint chips from mint chocolate chip cookies i made last week, so i will most definitely be making this sometime soon.
Yes, those Andes mint chips are so fun to bake with!!
I am feeling pretty lucky that I live with a Girl Scout right now 🙂 These look so yummy!
You are so lucky Amy!! Have fun with all those cookies 🙂
I need to find some GS cookies! Yum!
Seriously. I am hungry. Really hungry. But, these probably would not be a good thing to eat first thing in the morning. However, I will have to make them for the littles really, really soon.
Oh my gosh, these look like perfection!! Perfect way to use some of these eleventy boxes of Girl Scout cookies I’ve stashed in the freezer.
I may have over bought. It’s a problem.
I am guilty of the same problem! Had my hubby buy out the girl scout that came to his work, lol! WE are totally stocked up for a while.
wow, what a brilliant idea!!! looks amazing!! i still have yet to get my hands on some girl scout cookies!!!!
omg these look lethally good. your boys are just the luckiest. i love anything with condensed milk.
Me too, that sweet milk is so deadly!!
Thin mints are my favorite type of girl scout cookie. They’re addictive! These look delicious, I love the drizzled sweetened condensed milk, it really does make it gooey and yummy. This recipe will be bookmarked for sure!
Yum! I did something similar last week – I think I linked your original gooey bars recipe. Thanks for the inspiration – seeing as how I have about 6 more boxes of TM’s this is a great idea too!
These are perfect because I have exactly one sleeve of thin mints left. They will be meeting a gooey cake bar very soon 😉
Oh my goodness, these look great! However, somehow I missed all the girl scouts and have none of their cookies?! I’m thinking Keebler Grasshopper cookies would also work, but I might have to hunt down Thin Mints!
I like the minty flavor. The cool feeling when eating the cake makes it very delicious. =)
These look AMAZING! I just used up my thin mints for another fun treat, now I wish I had more to try this!
And apparently I need to get my hands on some Thin Mints immediately!
I don’t even have words for this, and I have to agree with Avery! The two of your and your GS creations!!!!!
I just saw Amanda’s and between yours and hers, VERY hard call to pick a winner b/c hers have peanut butter…but yours have mint. Both are faves of mine! And Thin Mints, hello, need a whole tube of those for a sitting 🙂
I love that you guys did this tag-team synced up post. So fun!
