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 ๐ 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 ๐
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!
