Chocolate Zucchini Bundt Cake

Jump to Recipe

Just a couple of days ago I tore off yet another page from the big family calendar hanging on my kitchen wall to reveal a fresh, new month.  There’s something cathartic about that process of tearing off the messy scribbles from a month finished, to reveal a pristine new one.  That simple experience gives me unexpected pleasure.  The first thing I always do to the clean new page is go through and mark significant days.  Today, August 3rd, got a sparkly flash of glitter washi tape.  I put it on there without even thinking because I’ve been doing that for 30-something years now.   August 3rd is my Mom’s birthday.  She would have turned 61 today.

I followed right along and started serving myself a piece as she walked with her plate into the adjoining butlers pantry to do something.  Right at that moment my grandma came down the stairs and in shock and horror, asked what on earth I was doing chowing down on cake at 9am.

“If your Mother only knew what you were doing right now, eating cake for breakfast?!”

Without saying a word I stealthily shifted my glance to the butlers pantry where my Mom was standing just out of sight from my grandma.  I will never forget our eyes aligning as she stood frozen, like a toddler caught with her hand in the candy jar.  She licked some stray frosting off her lips and with wide eyes and holding in laughter, shook her head in a desperate plea and slowly backed away as if I had never seen her.

I took one for the team that morning and ate a bowl of oatmeal for Grandma.  Later  we told her what had happened and we laughed hysterically for years afterwards about it.  I guess mothers are always mothers!

My mom loved chocolate and any excuse to eat more of it.  I’ve decided I’ll eat cake every August 3rd forever.  And then for breakfast on August 4th.  I was thinking about her when I made this cake because I know she would have loved this.

It’s packed with a generous amount of zucchini, which keeps it incredibly moist, even for days after (again, breakfast!)

Aside from having a rich cocoa flavor, it’s also studded with chunks of chocolate,

and then drizzled with the perfect amount of this fabulous glaze.  This is actually the same glaze that goes with the original chocolate-chocolate-chocolate bundt cake my grandma always made.

This is one of my most favorite cakes.  It’s great alone, or with a scoop of vanilla ice cream or whipped cream.

And because it’s super rich, you can slice it thin and it feeds a lot of people!

I hope you make it.  I hope you love it.  And I hope you save a piece for breakfast.

Happy birthday, Mom.

The ultimate chocolate zucchini bundt cake. Moist, tender, and delicious!

Ingredients

  • 3 cups all purpose flour
  • 3/4 cup cocoa powder
  • 3/4 teaspoons table salt
  • 2 teaspoons baking soda
  • 3/4 cup canola oil
  • 1 1/2 cups sugar
  • 6 tablespoons brown sugar
  • 4 eggs
  • 2 teaspoons vanilla
  • 3/4 cup sour cream
  • 4 cups shredded zucchini
  • 1 cup mini chocolate chips
  • Glaze
  • 3 tablespoons water
  • 1 1/2 tablespoons coconut oil or butter
  • 1 1/2 tablespoons corn syrup
  • 1 1/2 cups powdered sugar
  • 3 tablespoons cocoa powder

Instructions

  • Preheat oven to 350 degrees. Butter the inside of a bundt pan and dust with cocoa powder. Set aside.
  • In a medium mixing bowl, whisk together flour, cocoa powder, salt and baking soda
  • In the bowl of a stand mixer (or hand mixer) combine oil, sugars, eggs and vanilla. Mix to combine and then stir in sour cream just until blended.
  • Add zucchini until just combined. Add all but about 1 tablespoon of the dry ingredients to the bowl and mix until just incorporated. Add chocolate chips to the remaining tablespoon of dry ingredients and toss to coat them and then stir them into the batter.
  • Pour batter into prepared pan and bake.  Timing may vary based on your size and style of bundt pan, your oven, and the moisture content in your zucchini.  Mine usually takes 70-75 minutes.  Keep an eye on it and check doneness with a skewer- you want to see moist crumbs attached.  I would set a timer and watch after about 50 minutes.
  • Let cake cool on a rack for about 10 minutes and then invert to remove from bundt.
  • To make Glaze: combine coconut oil/butter, corn syrup and water in a microwave safe bowl. Heat for about 30 seconds in the microwave and then beat in powdered sugar and cocoa powder with a hand mixer. Let cool for a minute or two until it's a good glazing consistency and then drizzle over cake.

Notes

  • This cake actually tastes best when it is all the way cool. And I think it's even better the next day! Just keep it well covered to store overnight.

Questions & Reviews

  1. Today would have been my Mom’s birthday, the first since she passed. I found your recipe, and knew it was the one to make today. Thank you, and happy heavenly birthday to both our Moms ❤️

  2. Boy, you had me in tears recalling your mom’s memory. I lost my dear mom a couple of years ago and I can relate. She and I were always cooking or talking about recipes, favorite foods. I think about her when I’m cooking or baking. I’ll definitely be making your luscious cake and thinking about our moms. 🙂

  3. Your story about your mom and grandma touched my heart. Tomorrow is my mother’s birthday – she has been gone for 48 years…when I was a child I would not eat eggs – they just grossed me out…and mom was so afraid I would be malnourished without them…and so…I was banished to the kitchen to eat alone, where my brothers would not see that I ate angel food cake to “get my eggs”. All my relatives looked down on this practice but my health was a testament that it worked, wink, wink. I will make your cake tomorrow to celebrate my mom and eat a piece in bed at night and again for breakfast to celebrate your family!

    1. I wouldn’t glaze it the second it comes out of the oven, but it is okay to add the glaze when it’s just a little warm. I actually really like to slowly brush on half the glaze while it’s warm so it kind of soaks it up and then the rest when it’s cooled. If it’s melting off more than you’d like then just wait a little longer!

  4. Wonderful recipe and easy to follow. Makes a beautiful cake that will get rave reviews. It’s one of my favorite ways to use up zucchini when my garden is producing an abundance. This cake stays moist but there usually aren’t any leftovers! Enjoy

  5. I have made this recipe many times, i love it, so great for a garden loaded with zucchini, I just wanted to say “Thank you” for sharing a great recipe and your heart warming memories, it made me cry.

  6. 5 stars
    My kitchen smells delicious! I just finished making 2 cakes and they are in the oven! One I added cinnamon and honey bourbon instead of vanilla, we shall see! I am making them for my friends.

  7. 5 stars
    Today is my son’s 10th birthday, and he requested this cake, like he has for the past few years! It’s his favorite cake ever, he says. Thanks for a great recipe and a great tradition for our family.

  8. 5 stars
    This cake is soooooo delicious!!! I have so much zucchini that I’ll be making this every chance I get!

  9. What a sweet tribute to you mom and grandma. Can’t wait to make this-thanks for sharing!

  10. I never use corn syrup….I hate to buy a whole bottle just to glaze this…any other options?

  11. This cake is amazing!!! I use like 6-8 cups of zucchini because I have TONS of it. Everyone is always surprised there is zucchini in it — it is so moist and delicious! Thanks for sharing.

  12. Just baked this and it is gorgeous! It’ so high and pretty I almost hate to frost it. I must eat gluten free but I just told my son I baked him a cake for my birthday tomorrow!!!

  13. I loved the story. Also, I just made the cake with my granddaughter standing there drooling as I added the glaze. She licked that bowl clean and then kept trying to get into the glaze that had dripped from the cake and onto the plate. We have tried it and it is so much better than my other recipe that I will never go back. Thanks for a wonderful story and a wonderful recipe.

  14. love it! I was wondering if I could make it in any other pan? my bundt pan wont fit in my top smaller oven and of course my lower oven is broken at the moment!:(

  15. Such a heartwarming memory! I hope chocolate made that difficult day just a bit easier!

    Question: Would you wait to glaze it just before serving or is it all right ahead of time?

    I have a zucchini chocolate cake in the oven (a family recipe, but frankly yours looks better and I’ll make it next time!) and wanted to use your glaze recipe.

  16. Made this cake this weekend and it was delicious! I do have a question though. The glaze in your picture looks thick and yummy. Mine was so thin, it kept falling off the cake. I made the cake the night before and then made the glaze the morning of my party. I used light corn syrup, but that was the only change in the ingredients (butter as well but that was in the recipe. I haven’t yet used coconut oil). Help Please!

    1. You just put it on too hot. It thickens quickly and it just needs to sit for a few minutes until it’s a good consistency to spread/drizzle.

  17. Thank you for the beautiful post and memory!! I love how food not only fuels our bodies, but unites our relationships and forges memories.
