Holy smokes summer is coming to an end all too quickly. I’m trying to hold on to every last bit that I can, so today I’m sharing this amazing Blueberry Lemon Zucchini Cake. This delicious cake combines the best of summer into one delicious cake and I can almost guarantee you’re going to fall head over heels in love with it.
Coming from a die-hard chocolate lover, this Blueberry Lemon Zucchini Cake is easily at the top of my favorite cakes ever list.
The combination of lemons and blueberry is timeless (and delicious), and adding in zucchini is the perfect way to add moisture! Honestly, you won’t even be able to tell there is zucchini in this cake. If you’re not lucky (or maybe unlucky) enough to have a garden still full of zucchini, I bet you have a neighbor who does and who would gladly give you one or 10.
This cake calls for simple, basic ingredients that turn into one fantastic cake.

For the cake you will need:
- flour
- baking powder
- baking soda
- salt
- buttermilk
- lemons
- vanilla extract
- butter
- sugar
- eggs
- shredded zucchini
- fresh or frozen blueberries
For the glaze you need:
- powdered sugar
- half and half
- water
- lemon juice
A few simple tips. .
- Zucchinis that have grown to be colossal in size usually have large seeds in the middle of them. So if you’re using a massive size zucchini, be sure and cut it in half lengthwise and spoon/scoop out the seeds. I take a large spoon and just run it down the middle and the seeds come out easily.
- The skin on larger size zucchinis can sometimes be thick and tough, so I recommend peeling them or at least partially peeling them.
- Zest your lemons before juicing them. This makes it so much easier to get all of the zest from the rind! Also, room temperature lemons are easier to juice and will yield more juice.
Go ahead and indulge in this Blueberry Lemon Zucchini Cake and don’t feel guilty about it. I mean after all it does have a fruit and vegetable in it so it’s go to be healthy, right? (lol)
Oh and one last thing, if you’re worried about zucchini-haters not loving this cake, don’t be. You can’t even tell there is zucchini in it. In fact, if it wasn’t for the flecks of green, your kids would never know they’re eating veggies.

Instructions

Notes
- I partially peel my zucchini so I still some some green flecks in the baked goods.
