Thin Mint Truffle Brownies

JUMP TO RECIPE

Caution: Thin Mints were harmed in the making of these brownies.

It’s a hard reality, but sometimes you just gotta crush up those cookies to make something even more wonderful: Thin Mint Truffle Brownies.

So, I’m having a teeny tiny Girl Scout Cookie obsession right now. Is that a problem? No? Good.

A few years ago, I made these Oreo Truffle Brownies. I love Oreo Truffles, but I hate making them. All that rolling. All that dipping.

One day I said to myself, “why not top brownies with that truffle mixture?” And I did.

And it was awesome.

It was followed soon after by Nutter Butter Truffle Brownies. And, more recently, by Oreo Truffle Chocolate Chip Cookie Bars. When I started seeing the Girl Scout Cookies in my Pinterest feed I started thinking.

Thin Mint Truffle Brownies? And then I realized that, yes, they would be perfect.

And they are!

These are pretty much too easy to make (and eat). You do have to crush up some Thin Mint Cookies (two whole boxes), but it’s worth the $$.

{However, if you don’t want to grind $8 (or $10 if you live in the San Francisco Bay Area, apparently), you can substitute Keebler Grasshopper Cookies. They’re just as good and about ½ the price.}

Cookie truffles are made by grinding the cookies with cream cheese. Every cookie needs a different amount of cream cheese, so you’ll use a different amount with Oreos than you’ll do with Thin Mints. I used low-fat cream cheese for these brownies (as I do for most recipes). You can also use regular cream cheese.

When it comes to brownies, this is my favorite recipe. I’ve made it a million times, a million ways. However, if you can keep a secret…these are made with a box. You can use your favorite brownie recipe or your favorite box for these. Just make sure they’re completely cooled before putting the truffle mixture on top. Otherwise, it’ll rip up the brownie while you’re trying to press it on evenly.

The truffle mixture is very thin. I did this for two reasons: 1) Two boxes of murdered Thin Mints is enough and 2) Thin Mints have a strong mint flavor and the thin layer adds the perfect amount to the brownies.

Then, no truffles are complete without a coat of chocolate. You melt some chocolate chips and spread it all over the top.

Then? You get a fork and you attack the pan. Er, you cut them and serve them to your guests.

In a perfect world, my guests would be me, myself, and I.

It’s hard for me to say that these are the BEST Thin Mint recipe ever because Thursday’s post was pretty darn good.

But they’re tied. For sure. And they’re the BEST Truffle Brownies ever. That? I know for sure!

Thin Mint Truffle Brownies

Serving Size

Ingredients

  • 1 9 x13” pan of brownies baked and cooled
  • 52 Thin Mint Cookies or Keebler Grasshoppers from two boxes
  • 4 ounces low-fat cream cheese
  • 2 cups chocolate chips milk or semi-sweet
  • 1 tablespoon Crisco

Instructions

  • Place Thin Mints or Keebler Grasshopper Cookies in a food processor with the cream cheese and process until the mixture starts to form a ball. Alternately, you can crush the cookies in a bag without a food processor and then work in the cream cheese with a hand mixer and your hands until it comes together.
  • Crumble the mixture over the cooled brownies. Press to entirely cover. It will seem like there’s not enough, but there is. Just keep pressing (but gently, so you don’t rip the brownies).
  • Melt the chocolate chips and Crisco in a medium bowl on HIGH in 30 second increments, stirring between each. (It will take about 1 ½ minutes to become smooth.) Pour over truffle mixture and spread evenly. Chill until set.
  • Let the brownies sit at room temperature at least 20 minutes before slicing into squares. Store in an airtight container. They can be frozen for up to one month.

  1. Somebody left a box of Thin Mints to share in the conference room where I work. I had to have one every time I walked past that box. It was terrible/wonderful. These brownies sound serious. You don’t fool around, and that’s why you rock.

  2. Oh my gosh, totally drooling and wish these babies were in front of me now. Caution – it will not look very lady like once I start eating these but someone’s gotta do it 🙂 They are simply the best!

  3. Yummy! I think these are well worth the eight dollars! Unfortunately, I haven’t seen a girl scout selling cookies all year!

  4. Yup. I most definitely need these in my life right now. Guess I’ll be on the hunt for a pop-up Girl Scout cookie stand this weekend!

  5. In first look its amazing and delicious recipe ever seen, it takes more calories , , you should also make with low calorie sugar and natural sweeteners to some person, you can use lowkal sachet or lowkal cubes.

    1. I’m not sure how low-calorie sugar and sweeteners would work in this recipe. The brownie is from a box, and they do make sugar-free box mixes, but I wouldn’t sub those sorts of sugars cup for cup in a regular brownie recipe. The product would not be the same.

  6. Ohhhh wow these look so good! I actually don’t really like thin mints on their own (is that cookie blasphemy?), but I love them incorporated into other desserts. I think a whole lot more thin mints are about to be harmed…

    1. I like them, but I don’t like them because I can eat a whole box during one episode of Housewives. Er, not that I’d know or anything…

  7. Haha. Love your disclaimer : Thin Mints WERE harmed. Totally cute. These brownies are seriously fudgy looking, and that makes me seriously drooling.

  8. Heck yeah! These are some serious brownies! Chocolate and mint is pretty much my favorite thing right now. LOVE!

  9. I’m in love! These brownies are definitely the way to go instead of the balls. And they looks so perfectly chocolatey! I want to attack the pan with you.
