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!

    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 :).

  2. Helen Gibbs Holtan

    i would bake cookies cake and make bread. I would be able to make them healthier with the food processor! The possibilities are endless!!

  3. Amanda W

    I was just thinking of making a chocolate baked good with zucchini! It would be fun to use this mixer and attachment (in my FAVORITE color!) to try these muffins. Thanks Lauren!

  4. Erin

    I would make this new “christmas cake” recipe I found– it’s popular in Japan and is made of a sponge-like cake with a whipped cream frosting and strawberries in the middle (perfect since they’re in season right now).

  5. Sarah Christensen

    I’d make… uh… hmm… I want to say zucchini bread or something but I hate buying them out of season! So probably hash browns as part of a breakfast for dinner deal.

  6. Katia Audrey

    How lovely! I can’t wait to bake some of your mouthwatering cookies hehe! Keeping fingers crossed and hoping this is an international giveaway!

  7. Kristin Stanley

    Oh man I need a new KitchenAid AND a new food processor, so this would be so awesome to win! First I’d make a cake for Valentine’s Day then I’d use the processor to make salsa. Yummmmm

  8. Brandy

    I cannot even name all the things I would use it for. The first would probably be my middle daughter’s birthday cake. My hand mixer is just about worn out from all the cakes and frosting!

  9. Heather S

    I would first make my daughter a birthday cake 🙂 I’ve been dreaming about owning one of these beauties since I was 10! HA 🙂

  10. Heidi Colson

    what wouldn’t i make with a new kitchenaid?! I am really trying to ‘helthify’ my baking recipes. So I’m sure it would be something involving coconut oil and cookies 🙂

  11. Cheryl

    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!

    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.

  13. Allison Hutchens

    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. 🙂
