These Chocolate Zucchini Cupcakes will blow your minds! Soft, sweet, moist! The Poured Chocolate Frosting will make you want to never pipe frosting onto cupcakes again! This stuff is what dreams are made of. Basically like a cross between my Zucchini Brownies and Chocolate Cupcakes. YUM!

Chocolate Zucchini Cupcakes |A Chocolate Delight
These chocolate zucchini cupcakes with poured chocolate frosting…Lemme tell you, will change your life. They taste as chocolatey and sweet as they look and are pretty fast to throw together 🙂 Shredding the zucchini a little finer, wringing it out and then stirring it into the cake batter keeps these cupcakes moist while going mostly undetected because of all that cocoa powder. So delicious!

Main Ingredients Needed
Start by gathering up these ingredients to make these incredible Chocolate Zucchini Cupcakes:
For the Cupcakes
- Butter + Vegetable oil – to flavor and moisten.
- Sugar – to sweeten.
- Vanilla + Cocoa Powder – two flavoring ingredients. Vanilla is more subtle while the unsweetened cocoa powder makes these cupcakes chocolatey.
- Egg – used for structure and texture.
- Sour Cream – for creamy texture.
- Baking Soda+ Baking Powder – to help the cupcakes rise.
- Salt – to balance out all the flavors.
- Flour – this fills out the cupcakes.
- Zucchini – for its high moisture content. Be sure to wring out with paper towels before adding to the batter.
- Semi-Sweet Chocolate Chips – to sweeten and to add more chocolatey goodness.
For the Frosting
- Butter – for flavor.
- Chocolate Syrup – for that chocolatey flavor (I used Hershey’s brand).
- Milk – for a pourable consistency.
- Vanilla – for flavor.
- Powdered Sugar – to sweeten and to thicken the frosting.
- Sprinkles (optional) – add some red and white sprinkles for festive Valentine’s Day cupcakes.
How to Make Chocolate Zucchini Cupcakes |Directions
For full details on how to make Chocolate Zucchini Cupcakes, see the recipe card down below 🙂
Step 1: Preheat Oven + Grate Zucchini
Preheat the oven.
Wash and grate zucchinis. Wring out excess water and set aside. I used my stand mixer and grater attachment, but a manual box grater will do the job as well. Line muffin tins with paper liners and set them aside.

Step 2: Mix
Add butter, oil, sugar, vanilla, egg, and sour cream in the bowl of a stand mixer using the paddle attachment until light and fluffy. Slowly incorporate dry ingredients. Scrape sides of the bowl and stir again to ensure even mixing. Stir in grated zucchini and chocolate chips.
Step 3: Fill Muffin Tins + Bake
Scoop into lined muffin tins bake until completely cooked.
Step 4: Make Frosting
Once cupcakes come out of the oven, melt butter, chocolate syrup and milk together in a small saucepan. Once butter has melted and mixture has come to a light bubble, remove from heat and whisk in vanilla and powdered sugar until smooth.
Spoon over warm cupcakes and top with sprinkles if desired. I was a little heavy-handed, but that is not a bad problem to have. #Ilovechocolate
After everything cools, the tops start to harden slightly and they become even more amazing!

I would love to make a chocolate cake with this mixer!
Homemade marshmallows :). I have no mixer right now but have been wanting to make marshmallows for a year & I heard a kitchen aid mixer is the best for it :).
Cheddar biscuits! The food processor would allow me to get the cheese just right to incorporate into the biscuits 🙂
i would bake cookies cake and make bread. I would be able to make them healthier with the food processor! The possibilities are endless!!
I would bake up a storm, get the pasta attachment and make deliciousness all day long!

I want to make macarons!
I have been craving carrot cake, I think that would have to be made first!

Banana bread.
The first thing I would make is a rich creamy cheesecake.

I have grandchild’s birthday cake to make soon !
Looks delish!

How fun! A Kitchenaid mixer and attachment giveaway and just in time! My poor, faithful, 30 plus year old Kitchenaid mixer is so “crying” every time I use it! No, seriously! Being a scratch baker with 4 children, grand-children, heck, the whole neighborhood at times, it has been my constant companion in baking all kinds of confections through-out the years! Can’t forget the mashed potatoes, whipped cream, etc. I love the dough hook for making my own pizza dough and OMGosh yummy caramel rolls from scratch, too. (OK, so I have resorted to coaxing, gently telling my mixer it can do the dough one more time. So far, so good but know it is only a matter of time. Honestly, I would rather retire my old friend than have it die and a chance at winning would make that possible!). Thank you, Lauren, for the chocolate zucchini cupcake recipe…wow, the grater attachment would make so many things possible! Thank you to my Kitchenaid for all the wonderful memories we have made together through the years! (Oh, just between You and Me, Lauren, I do always include my secret ingredients…fun; an unexpected giggle-let the flour fly into the air; and a whole lot of LOVE in all you do!). Thank you for making me smile today. This is the first time I have posted a comment…it was fun! (Put your web URL in. Hope that was correct.). Happy Valentine’s Day to everyone! And congratulations to whoever the lucky winner is of this great giveaway!
A batch of cookies of course! 🙂

I would make desserts for our Bible study group. Thanks for the chance to win!!!
My family loves when I also make dessert for after dinner. So, maybe a cake of some sort?
Wow!! This would be so fun to have in my kitchen!!
I would like to make a pound cake first!

IT’S HARD TO NARROW IT DOWN. I WOULD LIKE TO TRY BREAD MAKING. I WOULD START WITH COOKIES FIRST THEY ARE MY FAVORITE THING TO BAKE.
I WOULD USE THE FOOD PROCESSOR ATTACHMENT TO SLICE VEGGIES TO DEHYDRATE.
I LOVE ZUCCHINI BREAD, PUMPKIN BREAD, AND CARROT CAKE.
I would love a KitchenAid mixer. Been wanting one for years! My sister has one and makes so much. Bread, desserts, mashed potatoes, etc. I love to bake, so I would say probably a dessert. 🙂
