{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.

For the Brownie Layer

  • 1 box of brownie mix (9×13 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 9×13 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.

  4. 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!

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

  6. 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?

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

      • 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!

        • Great! Thanks for coming back and sharing!

        • 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…

  7. 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

  8. They look divine! I am *so* making these for hubby’s burthday in March!
