World’s Best Chocolate Oatmeal Cupcakes

It’s hard to imagine a rich, dark chocolate oatmeal cupcake better than these.  These chocolate oatmeal cupcakes are unbelievably moist, tender, and worthy of both dessert and breakfast!  The super chocolatey frosting cools to a slightly crisp exterior, while staying soft underneath.  The whole thing is finger-lickin’ great!

World's Best Chocolate Oatmeal Cupcake

I know dubbing something “World’s Best” is a lofty thing.  Rare is the person (if one exists at all?) who has traveled the world, in search of the best chocolate oatmeal cupcake ever 😉

I enjoyed the recipe in the form of a pan cake, but everyone – kids and grown ups alike – shamelessly gushed over the cupcakes.  I mean, it’s so good.

I’d never think to put oatmeal in my chocolate, nor in my cupcakes.  Something about the quick oats makes these cupcakes beyond extraordinary.   You don’t taste the oatmeal at all, and nobody would guess these babies are semi-healthy because of a heaping dose of oats.

I had this recipe sitting on my cookbook stand, simply because the chocolate + oats intrigued me to no end.  Not to mention the chocolate-marshmallow frosting that forms a thin, crisp exterior while maintaining a soft texture underneath.  I’m not a humungous marshmallow eater, but I love the magic that can come out of it (Smores Chocolate Cookie Bars, yes?!)

The whole family lapped up every bit of this luscious frosting, which I totally prefer over traditional frosting.  And every crumb was somehow plucked up, leaving only very clean plates.

Tender, rich, moist, and uber chocolatey.  Loaded with the goodness of oats, which magically disappear into the batter.  Topped with a finger-lickin’ great chocolate marshmallow frosting.

Really, how can all that not be calling your name?  It’s calling mine right now.

World's Best Chocolate Oatmeal Cupcake with Frosting

I have a habit of using strong coffee (in my case, strong decaf) in lieu of water for almost all my chocolate cakes.  I promise you will not taste coffee, but what you’ll taste is a flavorful chocolate cake with with a delicious complexity.  Just gives it that extra oomph of yumminess.

These chocolate baby cakes rocked my world.  And apparently, everyone else’s.  Maybe that’s why they’re the world’s best chocolate oatmeal cupcakes. 🙂

These chocolate oatmeal cupcakes are rich, moist, and phenomenal! The quick oats lend a moistness and richness to the batter, though you won’t taste the oats. The frosting turns into a layer of chocolate softness with a slightly crisp exterior. YUM!

For the Cupcake:

For the Frosting:


  • Preheat oven to 350. Line muffin tins and set aside.
  • In a bowl, combine quick oats with very hot coffee, stir well, and let stand. Cover to keep warm.
  • Meanwhile: In the bowl of a stand mixer, cream butter and both sugars with paddle attachment, until smooth and creamy. Add vanilla and eggs, and mix well.
  • Add flour, baking soda, salt, and cocoa straight into mixing bowl, and mix with paddle attachment just until incorporated (do not over mix)
  • Add hot oat/coffee mixture to batter and mix until incorporated. Add mini chocolate chips, and stir by hand. If your oat/coffee mixture was warm enough, the mini chips should melt into batter during stirring.
  • Divide batter into lined muffin tins, filling almost to the tops. Bake approx. 18-20 minutes, or just until a toothpick inserted in centers comes out with few moist crumbs attached (not completely clean.)
  • Let cool in muffin tins.
  • To make the frosting: In a heavy saucepan, melt butter, sugar, and milk together over medium-low heat, stirring constantly. Bring to a boil, and immediately reduce heat to low. Add mini chocolate chips and marshmallows, constantly stirring until melted and smooth. Remove from heat, and allow frosting to cool about 10 minutes.
  • Stir again, and use frosting while it’s quite warm (not liquid, but not crystallized yet.) Spread onto tops of cupcakes, and let cool.


*Leftover cupcakes can be stored in airtight container at room temp for a day or two.

My FAVORITE, tenderest, moistest, yummiest Double Chocolate Cake with Kahlua Whipped Cream.  I want this for every birthday and every occasion that calls for chocolate.  This was one of my earliest posts upon launching the blog, and the photos need a redo pretty badly.  But the cake is my all-time favorite.  Unbelievably FAB!

    I just discovered this recipe – have to try it! Just wondered how many cupcakes does this recipe make? Didn’t see in your post. Thank you!!

      • Amy Dong

      Just edited to make it more clear – it makes 18 regular sized cupcakes 🙂

    Omg, the frosting is INCREDIBLE and so is the cupcake itself!! You are absolutely right, it doesn’t taste like oatmeal.
    I baked the recipe as they posted. I baked the cupcakes in silicone cupcake things, and they were perfect. I had extra chocolate frosting, so I pressed it into a big bar with parchment paper (after it cooled a bit) and put the bar and parchment paper in a freezer bag. When it froze it was like some kind of marshmallow fudge or chocolate candy. Yum!!

    Will definitely make again!!

    • Gaye Fisher

    could I change the coffee for coco powder in the same amount of hot water. we do not drink coffee – nor do wwe have any in the house.

      • chewoutloud

      Good for you for staying off coffee… I don’t drink regular coffee either, but I wish I wasn’t a decaf addict :). Yes, try the hot water with cocoa. That should be ultra chocolatey! Thanks for writing in, Gaye 🙂

    • huntfortheverybest

    i never had oatmeal cupcakes but they look great!

      • chewoutloud

      These took me by fantastic surprise, and they taste better than they look, believe it or not! 🙂

    • gottagetbaked

    Oatmeal chocolate cupcakes?! I totally need to try this recipe! These look fantastic, especially with that delicious layer of chocolate frosting on top. Because there’s oatmeal in there, this is appropriate for breakfast, right?

      • chewoutloud

      Oh, totally more than ok for breakfast! 🙂
