Thin Mint Brownies


Thin Mint Brownies – Fudgy Brownies with thin mint cookies in each bite!

Fudgy Brownies with thin mint cookies in each bite!

It is Secret Recipe Club time again!  Another month, another fun blog to look through.  This month I was assigned Megan’s Cookin’.  Megan has been blogging for a few years, so there were so many wonderful things to look through.  I had a really hard time deciding.  I almost made these Penguin Appetizers on cuteness factor alone.  This Linguini with Lemon Cream Sauce sounds like it would be great for one of my meatless meals, can’t wait to try it either.  But in the end, I went with brownies.  If you know me, that shouldn’t come as much of a surprise.

I completely missed Girl Scout Cookie season this year.  Probably for the best, when you think of it.  But still, disappointing.  I did manage to get my hands on one box of Thin Mints, so I could try these brownies.  I had one, and it was minty, and fudgy, and delicious!  I saved one for my 6 year old, and the rest went to school!  I had to get them out of the house quickly, before I ate the entire pan.  Good thing teachers appreciate baked goods :)

  1. Chocolate and mint is the BEST combo! Looks great.

  2. These brownies look incredible! Absolutely LOVE this use of thin mints…yum! :)

  3. I adore mint with chocolate…these look divine!

  4. hey erin! amazing looking brownies, i must say! i looooove GS thin mint cookies. (who doesn’t?!?!) i’ve seen a lot of brownie recipes that use cocoa powder instead of melted chocolate in brownies. using melted chocolate makes SUCH a difference. much more fudgy and rich :)

  5. You are a genius my dear! These look amazing and wouldn’t last 30 minutes in my house!

  6. These brownies look soooo delicious! Thick and Fudgy but with a crisp fresh aftertaste? Yes! 😀

  7. what a great use for thin mints! yum!

  8. These brownies look scrumptious!

  9. These look crazy good!

  10. Those look absolutely delicious–Thin Mints are such a classic, and I’m sure they’re great in a brownie!

  11. Yummy I haven’t had any good brownies lately :( Yours look amazing! Thanks for sharing!

  12. You’re so lucky that your school lets you send homemade treats! We can’t do that :-/ These look fabulous!

    • We can’t send in homemade treats for the kids, but the teachers will gladly accept it. I learned the hard lesson after I made a Christmas snack mix for the kids – got sent back to me :(

  13. I really like mint and chocolate… it’s so refreshing and tastes great after a meal. This would be the perfect little dessert. :)

  14. Oh this sounds really really good Erin..even though I am not huge fan of mint I could go for this right this moment!:))

  15. I love the addition of Thin Mints. I made some cheesecake thin mint brownies last weekend, they were a hit!

  16. I haven’t met very many brownies I didn’t like but I can tell I’d love these! How can I not with the addition of thin mints?! :)

  17. Great recipe!! I have a box of thin mints that I don’t want to eat, but crushing them into a brownie is a great idea!! This recipe is very simuliar to my brownie recipe, but your uses less butter! I love that!

  18. I love thin mints and I love brownies and I’m head over heels for this combination Erin!

  19. Two of my fave things…brownies and girl scout thin mints! Sounds minty delicious!

  20. I haven’t had one of these brownies in a long time. I use to be a leader and always had GS cookies around this time of year, so we mixed up more than our fair share of these brownies. Great pick! :)

  21. What a great recipe! They look like they turned out amazing.

  22. Haha it’s better idea to give away because this does look delicious indeed! I guess all the bakers have issues with portion control when they make delicious home-made baked goods. :-) We had to help out by buying girl scout cookies and there are a couple of boxes in my pantry. I really need to give those away before I finish everything! xD

  23. I’ve been trying to avoid the adorable Girl Scouts selling cookies, telling myself I don’t need them! But they’re so dang tempting. These brownies sound delicious, Erin!

  24. Ohmygodddd! This sounds amazing! I’m in love with girl scout cookies, tagalongs & thin mints to be exact! I would kill for these right now, it’s been years since I’ve had a girl scout cookie!!

  25. Oh, I’m so glad I have lots of Thin Mints in our freezer! These look fabulous, Erin!

  26. mmmmm. i love mint and chocolate together.

  27. I was just thinking the other day I have yet to buy any girl scout cookies. Are they really done for the year? Not that I need another box of cookies.

  28. —-I missed the Girl Scout Cookies this year, too…

    But can these by made w/ other mint cookies?

    They look Super :)

    • Yes they could. I think Keebler has a Grasshopper cookie that is almost exactly like a Thin Mint, you could use those for sure!

  29. All these Secret Recipe Club recipes are keepers! The thin mints are my favorite Girl Scout Cookies so I know I would have picked this brownie recipe too;-)

  30. Oh wow. These would be gone in ten seconds around here. That is like stuffing crack inside a crack brownie!

  31. Yum! I have one box of Thin Mints in the freezer…hiding from everyone! They would be thrilled if I made them brownies instead anyway!

  32. I haven’t had thin mints since moving to Australia in the last century. These look really good! I can’t wait to make these brownies!

  33. Haha, I hate mint, but my wife would literally steal the pan out of your hands! I just bought my first ever box of girl scout cookies – for her! But I do admit that samoas are lovely. 😉

  34. This is genius. What a great way to take one box of cookies and make it go so much farther. Well done!

  35. Ohhhh how I love the thin mint girl guide cookies. This is a must try.

  36. I like the combo of mint and chocolate. My kids and hubby LOVE it! We missed the girl scout cookies this season as well. It was the first year my daughter wasn’t in the girl scouts and noone came by! What’s up with that? I feel like we have been blacklisted since I pulled her out 😉 I haven’t even seen any booths set up. I’m going on a rant. Sorry. These brownies sound awesome! What a great SRC choice!

  37. I could go for a couple of those brownies right now.

  38. I have a Thin Mint weakness…these brownies look fantastic! I always try to miss Girl Scout cookies (as weird as it all sounds) but they are everywhere! Without even knowing Girl Scouts or having them knock at my door, I’ve bought way too many boxes outside of grocery stores lately :)

  39. good choice – who needs penguins when you have chocolate and mint?? wait, i take that back. i love penguins. but to hug, not to eat.

    happy src day!

  40. Absolutely perfect! Much like fruits and veggies….Thin Mint cookies are in season right now!

  41. Thin mints are such a weekness for me. I could eat a whole box in less than an hour! I love that you made them into brownies! I bet they were soooooo good!

  42. Oh girl, this is dangerous territory for me, haha! I would eat the whole pan!

  43. Your brownies look fudgy and delicious – something I would love to be sinking my teeth into! I love Megan’s blog – it is one of the first blogs I started reading back when I first started blogging myself. Her penguin appetizers are the cutest!

  44. How fun! One of my favorite brownie variations is adding york peppermint patties, and I can only imagine that Thin Mints have a similarly wonderful effect. (Pssst… there are cookies called grasshoppers that are similar if you miss the Girl Scouts!)

  45. These brownies make me all happy inside! 😀

  46. I only wish I missed Girl Scout cookies season this year! Mine are just sitting on the shelf untouched. Perhaps I’ll have to give these a whirl and use up those thin mints.

  47. These would do wonders for my current chocolate cravings!

  48. Wow! This is totally my kind of brownie… my husband doesn’t like mint (I KNOW!!!), and if I made these, I would have to share this with my two-year old who doesn’t even like desserts (who are these people I live with!!!)… I am going to save this recipe for an occasion like a pot-luck! Thanks for sharing :)

  49. Gah. What an incredible combination. I may not have any Girl Scout Cookies, but I’ll just head to the store and grab some Keebler Grasshopper cookies. They taste almost identical (and look almost identical too). These brownies are in my future.

  50. if the thin mint weren’t delicious on their own you had to add them to a chocolaty-heavenly brownie. So hard to resist

  51. I could seriously see myself eating the entire pan. Great sounding recipe.

    If you haven’t already, I’d love for you to check out my SRC entry: Broiled Sushi.

  52. I can’t resist a mint brownie! Looks like a delicious recipe that is simple to make yay!

  53. Don’t tell, but I robbed my dad of his thin mints… I love the buggers. These brownies really would be awesome right now.

  54. Now that’s a great use for thin mints!

  55. Aww… Girl Scout Cookies! I guess I’m kind of happy we don’t have them. I mean, they are pretty expensive right? Yup. That’s what I’m going to tell myself.

    And these brownies look great! I’m confused by the melted chocolate vs. cocoa powder discussion. I’ve always found the opposite! I’ll have to give melted chocolate brownies another try. :)
