{Get a Fork} Oooey, Gooey, Mint Chocolate Chip Brownies

Do you like sweet desserts? I mean really, really sweet? If so, this one is for you.

If not? Just have a small piece. With a large glass of milk.

These were partially inspired by Katrina’s mint-chocolate chip buttercream, although I did adapt it a bit. I love the combination of mint and chocolate, so I’ve wanted to make this recipe happen for a long time. Oh and I used a boxed brownie mix. It’s kind of what I do. I’m all about shortcuts.

If you’re like me? Make sure to buy the family size (9×13) box. More brownies = a very good thing.

Oooey, Gooey, Mint Chocolate Chip Brownies

Yield: 12-24 brownies

Total Time: 2 hours

Mint chocolate chip brownies so gooey you need a fork to eat them!


For the Brownie Layer

  • 1 box of brownie mix (9x13 size) + ingredients you need to prepare brownies (eggs, oil, water)
  • 1 cup of semi-sweet chocolate chips

For the Frosting Layer

  • 1/2 cup unsalted butter, softened
  • 1/2 cup shortening
  • 1 teaspoon vanilla extract
  • 1 teaspoon peppermint extract
  • 5 to 5.5 cups of powdered sugar
  • 4 tablespoon milk
  • 3/4 cup semi-sweet chocolate, grated or coarsely chopped in the food processor
  • green food coloring (optional)

For the Chocolate Layer

  • 2 cups semi-sweet chocolate chips
  • 1 tablespoon canola or vegetable oil


  1. Preheat oven to 350* Prepare brownies according to package, except stir in 1 cup of semi sweet chocolate chips. Bake according to package, in a greased 9x13 pan. When you throw it in the oven, take your butter out to soften for the frosting, if you haven't already.
  3. While brownie is cooling, make your frosting. Using an electric mixer, cream together butter, shortening, vanilla, and mint extract. Add in powdered sugar one cup at a time, and then add in milk, one tablespoon at a time until frosting is smooth and desired consistency has been reached. Stir in food coloring if desired, and then fold in chocolate shavings. Try not to eat it all at this step. Once brownie is completely cooled, spread frosting evenly over the brownie. Throw it in the fridge so that the frosting can harden. I'd say give it at least an hour, maybe two. You want it nice and cold--so it is firm.
  4. When it has cooled and firmed up, prepare your chocolate for the final layer. In a small bowl, combine 2 cups of chocolate chips with 1 tablespoon of oil. Melt in microwave or over a double boiler. If you choose the microwave, make sure to do it in thirty-second intervals and stir well each time. You don't want it to over-heat. Once it is smooth, spread it over the frosting layer and allow to harden.
  5. Enjoy and try not to go into a sugar coma. You can store these in the fridge or at room temp. They are easier to cut when they are closer to room temp (so the chocolate doesn't crack).


Verdict: Yum! I sent these off to work with hubs, had to get them out of the house, far too dangerous!
Husband’s take: The first time he had them he said they were a little rich. Then he told me he had one at work, straight out of the refrigerator. He detailed how he turned it upside down, ate the brownie first, then the frosting (“It tasted like mint-chocolate-chip ice cream!”), and then ate the chocolate layer. “It was so good!” So perhaps that is how it should be done.
Changes I would make: I might make the frosting layer a bit thinner. These were really, really sweet. I liked it, but not everyone likes such rich desserts. Or so I’m told.
Difficulty: Easy. A little time-consuming with the layers and cooling times, but not difficult.

  12. Leslie Means @ Her View From Home — October 26, 2011 at 5:30 pm

    These look so good! How cute would these be at Christmas?? All green and everything…love them! Only problem in my family – my husband HATES mint and chocolate together. It’s the strangest thing! So – can I just take out the peppermint extract? Yum…what should I add in it’s place?

    • Rachel — October 26th, 2011 @ 5:41 pm

      Hmm–a shot of espresso? Some Kahlua? Ameretto? You could go a cherry route…or just leave it vanilla with chocolate chips–that would be great too! Butterscotch would be yummy too!

  13. Claire @ Claire K Creations — October 26, 2011 at 6:39 pm

    Oh my goodness you’ve just managed to combine two of my favourite things. Brownies with mint?! I don’t think I’ll make these alone or I will be found passed out in a sugar coma!

    I bet I’d really enjoy this brownie. When I was growing up Mint Chocolate Chip was always one of my favorite ice creams. This looks fantastic!

    • Rachel — February 19th, 2012 @ 7:59 pm

      Thanks! I hope you love them!

  36. Jen — February 26, 2012 at 5:43 pm

    Just made these… AMAZING… I did add a little clear Wilton butter flavoring to the icing… do this with all my icing recipes and it cuts the sweetness… These are amazing

    • Rachel — February 26th, 2012 @ 8:17 pm

      So glad you liked them! Thanks for letting me know 🙂

  37. Taylor — April 27, 2012 at 4:25 pm

    I’m planning on making these this week for a friend’s bday. I think I’ll take your advice and lessen the amount of icing though. How much would you recommend reducing it by? A half, or is that too much?

    • Rachel — April 30th, 2012 @ 8:44 am

      If you reduced the frosting by half, there would still be PLENTY. I think that is a great idea.

      • Taylor — May 2nd, 2012 @ 12:49 pm

        I ended up making 2/3 icing cause my friend said was okay with sweet. They’re so delicious! I also only used butter in the icing, instead of butter & shortening and they still came out great (Just incase anyone is wondering if they can make them if they don’t having shortening on hand). Thanks for an awesome recipe!

        • Rachel — May 2nd, 2012 @ 6:53 pm

          Great! Thanks for coming back and sharing!

        • Kelsie — September 19th, 2013 @ 9:41 am

          Thank you Taylor, I was indeed wondering if I could use only butter because we like to use less-processed foods in this house which means lard or butter, not shortening 🙂 plus, shortening in frosting??? give me butter butter butter! probably going to make these for hubby’s 4th grade class (he makes treats for all of their birthdays (they request the treat) and tomorrow’s birthday girl requested mint choco brownies) and will cut down sugar/frosting because… well… they’re 4th graders and then he has to deal with them and 4th graders + sugar high = scary…

  38. Jaclyn — October 26, 2013 at 7:54 pm

    Oh my gosh these look insane! How I wish I had one right this second!

    • Rachel Gurk — October 26th, 2013 @ 8:32 pm

      Me too, girl!

  39. Carrie — March 12, 2014 at 11:06 am

    These look great! Just wondering if they hold up okay if you make ahead for a luncheon? Would they freeze ok? Any thoughts? Thank you!

    • Rachel Gurk — March 13th, 2014 @ 2:33 pm

      Yep! I’d definitely keep them in the fridge and they should freeze well too. Thanks!
