Today I'm sharing with you one of my all-time favorite recipes from my Grandmother. I enjoy making it for my family now. It's become one of Ethan and Olivia's favorites as well, and I think she would get a kick out of that!
Gram used to say that it was perfect because this chocolate zucchini cake recipe 'frosted itself'. She would include chopped walnuts with chocolate chips on top, but my family prefers it without the nuts. It's up to you!
This is the best chocolate cake for any chocolate lover!

🍴 Serving Suggestions
Just as Gram said, this is a perfect snack cake that requires no frosting because of the chocolate bits it is delicious with a little homemade whipped cream or homemade ice cream, too!
If you prefer, you could add a layer of vanilla or chocolate frosting to the top.
⏲️ Storage
This cake will keep at room temperature for about 1 week in an airtight container. (These are my favorite airtight containers.) However, if it is very hot or humid, I suggest storing it in the refrigerator.
📖 Variations
- You can substitute half of the zucchini with a grated carrot or apple.
- For a slightly healthier cake - that's an oxymoron right?? - substitute half of the vegetable oil for a fruit puree like banana, pumpkin or applesauce.
- For the topping, use any combination you like of dark, semi-sweet or even white chocolate chips.
- You can add ½ cup of your favorite chopped nuts to the batter if you like.
- This cake can also be made in a bundt pan if you like. It looks beautiful dusted with powdered sugar. You can also make it in two round cake pans. Obviously, the time will change a bit for different-sized pans.
