Sometimes I think I should rename this blog to “Crazy for Crust and Brownies” because I love brownies almost as much as I love crust and pie.

These brownie cupcakes? Are making me think even harder about doing that. If you’re looking for a super fudgy, rich, and decadent brownie cupcake, you’re in the right place.

Can we talk about St. Patrick’s Day and school for a minute? Great, thanks.

When Jordan was in preschool they got all into the leprechaun thing. The leprechauns would destroy the classroom on March 17. This spilled over into home life, a place where previously leprechauns did not dwell. It also caused no amount of distress for weeks leading up to the big day.

Much like Santa, France (the elf), and the Easter Bunny, Jordan was (is) scared to death of leprechauns. As in: won’t go in her room alone. Won’t go into a dark room, period. Every March was just so much fun.

Then we got to third grade. I was all FINALLY. They’re too grown up now. We can finally come out the other side of leprechauns. I was wrong.

Last week Aimee posted about how annoying it is to make leprechaun traps as a school project, because inevitably the parents have to make them and if you’re like her (or me) the kid has to do their own homework so they go to school with scotch taped shoe boxes and the other kids have PVC pipe and wood and nails and everything their parents built. I sympathized with Aimee, secretly glad we’d never have to build a leprechaun trap.

I got cocky people. Then I got handed my just desserts. Guess what’s due on March 17 in Jordan’s class? Yup. A freaking leprechaun trap using no less than 3 simple machines (whatever the heck those are). The pictures online and in her assignment make it obvious that her dad and I are, in fact, supposed to build the trap for her. Pipes and pulleys, glitter and paint and gears and shifts, oh my.

Kids should be able to do their own homework. They should be able to think up an idea and build it on their own, with only a little help from parents. That is the point of school work. But I hate to tell you: there is no way Jordan will be able to conceptualize and build a leprechaun trap on her own. Enter: her dad and I.

And, even better? We get to store a leprechaun trap in our house until it’s due on the 17th. We have to keep something in the house that supposedly draws in what Jordan is afraid of. So yeah, she’ll probably be sleeping with the light on for a week. IF SHE SLEEPS AT ALL.

Okay. That’s it. /rant

So, did you read the whole thing? Or just join in now? Either way, you’re in for a treat. The only thing I like about St. Patrick’s Day? The food. Namely: Mint and Chocolate.

Or, in this case, Mint Chip Brownie Cupcakes.

As you all know by now, my daughter is obsessed with Chocolate and Mint. The only problem I have when making  these sorts of treats for her is that she hates dark chocolate, so cupcakes and cake are iffy. But brownies? She always loves brownies.

These cupcakes started off with my favorite One Bowl Brownie recipe. I simply put the batter into a muffin tin instead of in a 9×9 pan. Easy peasy! The recipe is, literally, one bowl and a wooden spoon. You have to melt the butter, but not any chocolate so it’s even easier than my other favorite brownie recipe.

{BTW, if you don’t want cupcakes, make the brownies in a 9×9″ pan and frost them with the frosting. Voila! Traditional brownies.}

This recipe makes 8 standard sized cupcakes. You have to scrape the bowl to get every last drop of batter, but you’ll get 8. It’s a small batch, which is perfect when you don’t need a gazillion cupcakes. If you want more cupcakes you can double the recipe. You can even use a box brownie mix in place of my recipe, if you want something super easy.

The frosting is thick and rich, and tastes just like Mint Chip Ice Cream. Be careful when adding the peppermint extract – I always err on the side of caution and add just a bit. Too much peppermint extract and you end up with toothpaste. Taste as you add, you can always add a little more.

BTW, in case you don’t know, peppermint extract is very different from mint extract. To me, mint extract tastes like toothpaste even in small doses. Be sure you buy peppermint extract!

These cupcakes are very, very rich. Even though she and I each ate a whole one, we probably could have split one. Since I made these cupcakes, I also used the same recipe to make mini brownie cupcakes. If you want a more manageable, less rich and smaller cupcake, use mini muffin tins. It’ll make about 24-28, baked for about 9-11 minutes.

I think brownie cupcakes are my new favorite cupcake.

See all that fudgy goodness? #totalwin

I’d much rather celebrate St. Patrick’s Day with these than with a leprechaun trap. And they’re probably easier to make!

Servings: 8 cupcakes

Mint Chip Brownie Cupcakes



  • 1/2 cup unsalted butter — melted
  • 1 cup granulated sugar
  • 2/3 cup unsweetened cocoa powder
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1 tablespoon brewed coffee — or you can substitute water
  • 1/4 teaspoon salt
  • 1/2 cup all-purpose flour


  • 1/2 cup unsalted butter — softened
  • Pinch of salt
  • 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon peppermint extract
  • 2-5 tablespoons heavy whipping cream — as needed for consistency
  • 2-3 drops of green food coloring
  • 1 cup mini chocolate chips — divided


  1. Preheat oven to 350°F. Line cupcake pan with 8 liners.
  2. Stir together melted butter, sugar, and cocoa. Stir in eggs, vanilla extract, coffee or water, and salt. Carefully stir in flour. (The coffee just adds a richness to the brownies, but you can use water if you prefer.)
  3. Place about 1/4 cup of batter in each cupcake liner. You’ll have to scrape the bowl with a spatula and get every drop of batter, but you’ll get 8 cupcakes.
  4. Bake for 16-18 minutes, until a toothpick comes out clean from right along the edge of the liner. (The toothpick will still be full of batter from the center, but you don’t want that clean or your brownie will be dry.) Cool completely before frosting.
  5. Make frosting: beat butter and salt until smooth. Slowly mix in powdered sugar until crumbly. Add extracts and 2 tablespoons of heavy cream. Beat until smooth, adding more cream as needed to get the consistency desired. Stir in 1/2 cup mini chocolate chips. You want the frosting stiff enough to hold up on it’s own. Frost cupcakes as desired. I used an ice cream scoop to scoop a 1/4 cup frosting onto each cupcake. If you wish, melt the remaining mini chocolate chips in a microwave safe bowl (in 30 second increments, stirring between each) and then drizzle over cupcakes.
  6. Store in refrigerator loosely covered, serve at room temperature.

  1. SO GLAD we have never had to endure the making of a trap! Let’s just HOPE we never will!! I haven’t had breakfast yet, you can eat these for breakfast, right?! 🙂

  2. That frosting just looks so perfect! Like mint ice cream on top of cupcakes…I need it 🙂

  3. Oh man!! Now that frosting I could just eat with a spoon! Love this Dorothy!

  4. I’m in love with everything about this recipe!!! A brownie cupcake? I am in Heaven!!!

  5. I puffy heart love brownie cupcakes. They are so much fun to eat vs a square brownie. I realize they taste the same, but it is the shape that I adore…and they seem a little more fudgey that way! I also am in love with the amount of frosting you have on these…perfect ratio 🙂

  6. I am loving your small batches! 8 is the perfect amount because if I made a whole batch of these I know I’d eat them all! And it’s better to just eat 8 right? 😉 Gorgeous photos! Pinned 🙂

  7. The cupcakes are beautiful! And you know the worst part of the making of the leprauchan trap, right? Some parent who is an engineer, married to a professional designer, will make something totally intricate, using all kinds of professional materials.

  8. Well, whatever your trap ends up looking like, you’ll have the perfect “bait” to use! Maybe these cupcakes can be the trap???? Just tell the teacher that you put some sleeping pills in the frosting so the leprechaun will fall asleep after eating!!!
    Love any brownies, Mom

  9. THAT IS INSANITY! That’s really annoying that they assign homework that parents pretty much have to do. ridiculous. ugh.

    also…leprechaun traps? really? lol weird

    At least you have treats like this to make you feel better. I love that they’re brownies and so chocolatey and fudgy and then have that awesome big scoop of minty delicious frosting on top!

  10. You should bring these cupcakes as a mean teacher trap! When when goes for it…snap!!!
    You poor thing!
    These brownie cupcakes will ease any trap pain!

  11. I have a very vague recollection of having a similar assignment as a child…it’s too bad you can’t just say that these ingenous brownie cupcakes are the trap, and that a mixer was involved in their creation (and everyone knows a mixer is far more complex than pulleys, wheels, or wedges, so the mixer alone more than fulfills the machine requirement)! Good luck!

  12. WOW, that frosting looks amazing, I just want to eat it with a spoon! I love that you made these brownies into cupcakes, pinned 🙂

  13. Dorothy, your photos are killing me! That giant scoop of frosting on top is calling my name. These are absolutely glorious! As for the school assignment, my parents NEVER helped me with anything growing up. Seriously. They were too busy working and it was totally up to me to do homework, assignments, projects, etc. I have NO idea how you’re going to make that trap (I’m not scientific or logical or engineering minded whatsoever). Good luck, girl! Will a noose tied to a branch work? Y’know, like in old school Bugs Bunny cartoons? Take a cue from Wile E. Coyote…although I don’t think his traps ever worked. Maybe just eat a few of these delicious cupcakes while you think about it!

  14. These cupcakes are killing me. I love EVERYTHING about these. So jealous I’ve never thought about turning brownies into cupcakes, especially since I have brownies on my mind basically 24/7. Hope you’re having a wonderful Sunday!

  15. we’ve been blessed with never having to make a trap 🙂 but I;ll take the brownies for sure

  16. Ugh. I am so not looking forward to all of the homework in my future :/
    And, uh, these cupcakes are awesome. You read my mind 🙂

  17. I would love a big bite of that frosting right now!! Yummy!

  18. That is the thickest most delicious frosting that I have ever seen! I need these brownie cupcakes in my life. They are ADORBS!

  19. What does a leprechaun trap have to do with education? It makes no sense. Really, what are the kids taking away from this whole project. I say you send in one of these cupcakes with a note that says leprechaun bait. It has three enticing parts: brownie, frosting, chocolate drizzle. I mean, there’s no way a leprechaun can resist a brownie, right? Love these. Pinned. Good luck with the trap.

  21. Wowza these look amazing! Love that big generous scoop of mint frosting on top!
    btw Leprechaun Trap??? What the heck… never had to do those when I was in school thank goodness!

  22. Crazy for brownies sounds good to me! Wow, I love how that frosting looks like ice cream – I want to lick my screen really badly right now – is that bad? 😉 Good tips on the extract – I’ve only used peppermint, glad to know I got the right one!

  23. I am so in love with these Dorothy! They look absolutely perfect! That scoop of icing on top is calling to me! Sorry about the leprechaun trap. I can’t believe that can even be called homework. #crazy

  24. Your cupcakes look wonderful. I could eat a big scoop of that frosting! YUM!

  25. Brownies with mint chocolate chip frosting that looks like a scoop of ice cream! Just stop it! Stop it right now. I’ll take five. And who exactly is worried about these being too rich? Is that possible? I’ll answer that one – No, no it is not.

    I’m sorry but expecting parents to make any sort of trap is just ridiculous. Kids should be expected to do their own homework otherwise they aren’t learning anything except that they need mom’s help to do anything right. NOT helpful. And a leprechaun trap? Don’t get me started. You poor thing.

  26. I feel like maybe I jinxed you, hehe!!! At least your husband is willing to take this project on. Maybe you can make some more of these brownie cupcakes to enjoy while they create traps, hehe!!

  27. I don’t know about Leprachan traps but these mint browine cupcakes are amazing!! Couldn’t you just put these cupcakes in a box and call it a day?? I mean, what leprachan in his right mind wouldn’t come running for these??? 😉

  29. Yes. I love everything about this. A brownie disguised as a cupcake so it can be extra heavily frosted is so genius, and the fact that the frosting highly resembles mint chip ice cream…ugh, NEED! Pinned 🙂

  30. These cupcakes are beautiful Dorothy! Brownie cupcakes? I am in heaven and especially drooling over that perfect scoop of mint frosting on top! Sorry about the leprechaun trap – I wonder if you can use these as bait? How can anyone resist one of these – I know I sure wouldn’t be able to. Pinning 🙂

  32. Just wait until high school physics class when they have to make a rube goldberg machine! The leprechaun trap will seem like a fond dream;( These cupcakes look amazing and I think that they will be perfect for my birthday this week. Happy Birthday to me!!

  33. Dorothy, you poor thing!! Making a leprechaun trap was never any fun, even when I was back in elementary school and made it from a cardboard box (or shoe box, I can’t remember). I think we only did them in first grade; after that, we mainly celebrated with green cookies and cupcakes while the teachers tried to make sure nobody pinched each other. (Good luck on that one.) If you kept the leprechaun trap in the garage, would Jordan finally be able to sleep like normal??

    I’m SO right there with you on brownies — probably my favorite dessert ever! You’re so sweet to make a mint-flavored frosting in honor of Jordan too. You definitely earned the “Best Mom” award for this recipe! 🙂 I bet you could add an Oreo crust to a brownie cupcake and combine your two favorites into the best treat ever. But then again, knowing you and how much you think/bake, you’ve probably done that already!
