Girls Scout Thin Mint Fudgy Brownies

by on May 21, 2011

Phew. Its Girl’s Scouts camping weekend again. S’mores, rain, cornbread and chilli. This year, the girls go…and the boys stay home. And you – well you get the brownies…..the thin mint ones. Forget After eights, these rock!


In my narrow tunnel of a mind (at least when it comes to football related issues), the season never ends. Once the ‘soccer/football’ league is over, friendlies begin and before you know it…..the cycle begins again.

Somewhat analogous, some might say to the hoarders. But not in the clinical sense. In the case of Girls Scout cookie, the collectors keep the boxes hidden away…till the main selling season is over and then during the ‘break’, they help themselves to box after box…in a paced manner of course till the cookies go into steady decline by which time the cravings are assuaged and its almost time for the ‘league’ again.


Well, that is except they are novices and this is only their second year of selling cookies….like me. In that case, they buy a case of 12 cookies, give them away will nilly and then over lunch with some GS veterans mention their dwindling stockpile. Only to see heaves and puffs and mention of serious treasures of thin mints (perfect frozen in the summer) and other flavours. At which point this little girl sighs to herself. Next year can’t come soon enough. She makes a stern promise to herself to remember to remember to keep some away, so when the low season comes, she has some to hand!


Now, I’d always avoided thin mints, never tasted them because descriptions of ‘Its like After 8, but in a cookie’, put me off. I imagined sticky, creamy, overly sweet filling and I stayed clear. I turned the corner when I actually opened a packet and tasted one and discovered that whilst it had the fragrance and ‘aura’ of the dinner sweets, it had class and character all its own. And then I thought of how the same freshness in a fudgy brownie. And the rest was history. Expecially spurred on by David’s own version of Thin mint brownies.


Except I also had chia seeds, which I love baked for their marvelous crunch. And nutrition.

And so I took

A brownie fudge recipe from Celia

Added some crushed thin mints

And topped with chia seeds

Baked….and perfect in no time.

Enjoyable in the lull. And hopefully, next season too.


Brownies to keep my mind warm as we head north, to camp. And chilli and s’mores.

Pray it stays dry this weekend. Please?

Love you too!

Chia Thin Mint Fudge Brownies, adapted from Celia of Fig Jam and Lime Cordial

16 thin mint cookies, broken into medium sized chunks
1 – 2 tablespoons flaked almonds, raw or toasted (optional)
90g unsalted butter
200g milk chocolate
120g caster sugar
1 teaspoon vanilla extract
1/2 – 1 teaspoon (saigon) cinnamon powder
Pinch of salt
2 large eggs, room temperature
60g plain/all purpose flour, sifted
2 tablespoons dutch cocoa powder, sifted
100g milk chocolate chips
2 tablespoons chia seeds

How to

Preheat the oven to 175C and line a 20cm pan with greaseproof paper. Spread half of the cookie chunks at the bottom of the pan along with the flaked almonds.

In a saucepan, melt the butter, then add the chocolate and stir over low heat until melted and smooth. Remove from the heat and stir/whisk in the sugar, vanilla, cinnamon powder and a pinch of salt until combined. Add the eggs, one at a time and whisk to combine. Fold in the flour and cocoa powder with a spatula, until well combined and the texture of the batter changes from fluid & grainy to somewhat smooth and thicker. Sprinkle the chocolate chips over the top and gently fold in.

Pour the batter into the tin, and then sprinkle the remaining crushed cookies over the top. Follow with the chia seeds.

Bake 30 minutes until just firm – don’t open the oven to check in the interim…please and even if you do, don’t press down on the top of the brownies……

Gently lift out of the oven and allow the brownies to cool completely in the tin.

Once cold, carefully lift out paper case and cut the brownies….to desired portion.


I loved the brownies – best eaten in small portions. The cookies and chia seeds made the top and base crunchy and the middle was gooey and fudgy and sweet. I put them in a ziploc in the fridge and ate them in tiny squares. They were quite sweet, perfectly paired with cold, dark coffee, which I don’t drink often by the way but lets just imagine I do!

    yum! i love the addition of chia seeds 😀

    Great sounding brownies, though I am obviously out of the loop when it comes to thin mints – this is the first time I’ve heard of them. Chai seeds I’m just about to look up on the internet.

    I’ve just been reading your post about silicone bakeware. Glad you generally approve. I’ve been using it for about 10 years now and it revolutionised my baking life. I use a loaf mould to bake my bread and I also use a metal tin for the other loaf. They both come out the same except that the silicone has a rather bendy shape as it’s not strong enough to hold bread dough – but I’m happily living with that.

      Choclette, I still love my silicone bakeware. Its wise, as you mention to be aware of the differences between it and metal! And glad that you’re now completely int he loop about Thin mints and chia seeds…so when they roll you’re way, you’ll be ready!


  • May 26, 2011 at 10:36 PM

    Love thin mints so you know I am all over this! yum!


    • May 29, 2011 at 5:02 PM

      Thanks Wizzy, wish I could send you some!

      Steve, so glad you think Muppet might like these. She’s my rising food hero!

      Thanks Natasha. Chia seeds are great, aren’t they. Powerfood extraordinaire

      Amanda…..perhaps I should have written, best to aspire to eat these in small portions….even if the reality differs!


  • May 24, 2011 at 5:09 PM

    Oohh…now you’re talkin’ my language, Oz. My young Muppet will be all over these like white on rice! Happy camping! – S


  • May 24, 2011 at 4:41 AM

    Awesome brownies! I’m especially excited to see chia seeds – I’m making everything with them right now!


  • May 24, 2011 at 1:58 AM

    Best eaten in small portions, you say. I doubt that I could manage that!


  • May 23, 2011 at 1:59 PM

    I’m missing out, I’ve never had a Girl Scout cookie before. I’ll have to try the brownie, it sounds incredible. Hope you and the girls have a lovely time camping, enjoy those s’mores!


    • May 29, 2011 at 5:04 PM

      Oh Shaz, I wish I could promise to correct the fact that you’ve never had a GS cookie before. To be honest, up till 3 years ago, I too said the same. Lets live in hope ok? And camping was fun, thank you!

      Oh Blonde Duck, I wish I’d tried this when i had a health pile of cookies. The idea of Samoa blondies is thrilling!

      Emily – take a virtual bite. Please.

      Oyster Culture, I like evil genius :-), and take it as a compliment of the highest kind – no need for any apologies. Thank you for making my head swell and tilt!


  • May 23, 2011 at 1:15 PM

    Man, if you had samoa blondies, I would die right now.


  • May 23, 2011 at 9:46 AM

    These look awesome! I want one right now!


  • May 23, 2011 at 1:09 AM

    Oh my goodness, I think I called you an evil genius before (in the best possible way) and now I really mean it. You are going to get me in so much trouble. I will now obsess until I try these for myself.


  • May 22, 2011 at 11:11 PM

    As an experienced Girl Scout cookie connoisseur I can assure you that you will find at least two boxes left in my freezer. I think I would have to warm my brownie and top it with some vanilla Ice Cream…maybe for my last box of Thin Mints I may have to make this and serve it with my Thin Mint Irish Coffee!


    • May 29, 2011 at 5:08 PM

      Rhonda dear, I loved the look of your thin mint coffee. I just wished I was neighbours with you, coming round at strategic times and requesting specific cookies for coffee!

      Norma, thank you dear.

      Penny – let me know if you like them, if you do try. Brownies are great bites to have on hand, don´t you agree?

      Celia, thank you for compliments, make me smile. And head swell!

      Sally, trust it to rain when you go camping. It did rain but we faired well, overall…and even managed to have fun!

      Monet dear, I hope you’re well. No apologies needed….All my love and strength and prayers to you!

      Thanks Maria

      Glad you like them Angie

    Leave it to you to come up with this recipe. I am a lover of the thin mint cookies….When given a chance I buy quite a few. Thanks Oz…


  • May 22, 2011 at 2:10 PM

    Was going to make brownies today but did not. I think this is a much better version to try out


  • May 22, 2011 at 11:31 AM

    Oz, you’re always so clever! Thanks for the mention, although hardly needed here – you’ve morphed the brownies into a whole original (and totally marvellous) treat! 🙂 xx


  • May 22, 2011 at 4:54 AM

    I hope it stays dry for you too. When I was a girl guide (a VERY long time ago) we camped in the worst rain for 40 years.


  • May 22, 2011 at 4:45 AM

    My dear friend…these were my sister’s favorite cookies growing up…and these bars look like such a wonderful adaptation. Thank you for sharing with me tonight…I’m sorry I’ve been gone so long! Your blog continues to bring a smile to my face. I hope you have a blessed Sunday!


  • May 21, 2011 at 11:10 PM

    Yum! They look so scrumptious!


  • May 21, 2011 at 6:44 PM

    Those brownies look moist and divine!


  • May 21, 2011 at 4:47 PM

    These look heavenly…or should I say sinful! I have not use chia seeds before I will have to try them. Of course it’s not Girls Scout cookie time here, and no stash. 🙁
