Candy Corn Cake Bars: chocolate cake topped with vanilla buttercream and Candy Corn m&ms

This my friends is a total cheat dessert.

Sometimes in the middle of the day, I get cravings.

Severe. Frosting. Cravings.
Yes, you read that right. This dessert is all about the frosting. The cake is just a slightly doctored up Duncan Hines Fudge Cake Mix.

Then it’s topped with a fluffy vanilla buttercream frosting.

And sprinkled with Candy corn m&m’s.

Yes. I think they really do taste like candy corn. But I know many of you won’t be able to find them. So throw on the real stuff and that would be cute too! It tastes so good with the buttercream frosting.

Best part? You bake it in a 15×10 baking sheet…that makes a lot of cake bars! Just sayin. And if you put these in an air tight container, the frosting keeps the cake moist for up to a week! Maybe longer…but I wasn’t able to test that theory. Ours lasted 5.02 days. The .02 is that is about how long it took me to eat the last cake bar after waking up and pouring my coffee.

  1. How delicious!! I think I share your icing cravings, too. haha. 🙂 I like the contrast of chocolate and vanilla so I would love these treats. Candy corn over the top would be adorable for October!

  2. Mmm yummy! The cake mix looks so fudgy as you said, and love that you added a contrasting layer of the vanilla buttercream. The candy corn M&Ms look fantastic too. We don’t get them here but they sound equally delicious.

  3. Where’s the candy corn??? Jk. I mean, I’ve eaten an entire bag of those white chocolate m&ms in the last week (who hasn’t?), but I’ve also eaten 2 (maybe 3) bags of candy corn by myself in the last week. So. I get extra excited when the see “candy corn” in the title of anything.
    I made candy corn blondies last year and candy corn is tricky too bake with! It takes on the character of caramel and oozes and sticks.

  4. I have days where I crave frosting too:-) Whenever I have a cake order, I save the extra frosting and refrigerate it for those days! I love how chocolatey and fudgey your bars are! Plus the black and white with the fun m&m’s is the perfect Halloween treat!!!

  5. I loooooove this cake. That frosting…I’d eat it without the cake!!! You eat my kind of breakfast.

  6. Sometimes I cheat with cake mix too Aimee! 🙂 I have yet to try those candy corn M&Ms!! My sister both texted me the same day telling me I must buy them. They’re on my to-buy list!

  7. This looks amazing!I have been hearing about the candy corn m&m’s!Thanks so much for sharing!

  8. Haha, these wouldn’t last that long here either! They look so moist and delicious, and that frosting is so insanely fluffy, I’m surprised it actually made it onto the cake bar (I probably would have caved and stuck my face inside the mixing bowl!) PS, candy corn M&M’s rock and I think they taste like it, too!

  9. I love it! I have been wanting to try the M&M’s Candy Corn. This is a recipe I have to make! Thank you!

  10. These are so pretty! You should add them to the #BYOBRownies party myself and three other bloggers are throwing today

  11. So easy but SO good. Please send me a slice 😉

  12. I LOVE those candy corn M&Ms. I made the mistake of buying a bag last year and putting them in my desk drawer at work…they were gone about two days later. Oops! I love how the colors pop against these cake bars–so festive!

  13. Hi Aimee. My name is Emily and I am an editor for I recently wrote a blog post on about candy corn and featured your recipe. You can check it out here: These bars look so delicious!

  14. Oh yes, sometimes you just need something to hold the frosting besides a big spoon! I may have to go find those M&M or maybe I’ll just go through my secret (kids don’t know where it is) stash and see what I have on hand!
