Blueberry Zucchini Poke Cake is so tender, moist and delicious. Made with zucchini, olive oil and lots of fresh lemons, this cake is just amazing!

Poke Cakes are very popular on the blog because they are so easy to make, look stunning and taste delicious. Having already so many tasty poke cakes, like this Strawberry Poke CakeGerman Chocolate Poke Cake, and Baileys Poke Cake, it only made sense to add a Blueberry Zucchini version to the mix.

Homemade Blueberry Zucchini Poke Cake

Blueberry Zucchini Poke Cake is the only cake I want to eat all summer long. The cake is very, very easy to make, so don’t be fooled by it’s pretty look. I have said it many times on the blog that I am a huge fan of moist and tender cakes. This Blueberry Zucchini Poke Cake is so tender, it melts in your mouth.

The cake is packed with grated zucchini, lots of fresh lemon zest and juicy blueberries. The olive oil gives it an incredibly rich and moist crumb. The cake is moistened using a sweet white chocolate sauce and topped with refreshing lemon buttercream.

Blueberry Zucchini Poke Cake Recipe Tips:

  • Make sure you drain as much water as possible from the zucchini. After I grated them, I placed them in between two cloth towels and pressed really hard to squeeze all the water.
  • When you measure the grated the zucchini, make sure you do it AFTER you squeezed the water. Pack the cups tightly with grated zucchini. I used 1 1/2 medium zucchini.
  • Using a cake mix will reduce the prep time. You can use the Yellow Cake mix or White Cake mix.
  • Also, Do NOT use frozen blueberries in this recipe, their water content is too high. Use fresh blueberries.
  • Similarly, you can skip the blueberries or replace them with fresh blackberries, raspberries or diced apples.
  • Based on reference, you can add 1/2 cup of chopped walnuts or pecans into the batter.
  • Let the cake absorb the white chocolate mixture for at least 8 hours in the fridge before serving, this will make the cake extra tender.
  • Keep the cake refrigerated as the frosting will soften if kept at room temperature for too long.
  • You can either pipe the frosting on top of the cake, or just spread it evenly with a spatula.
  • Clean the knife after each cut, otherwise, the slices will be messier, since the frosting may stick to the knife.

Tools/Ingredients I used to make this Blueberry Zucchini Poke Cake Recipe:

  • Non-Stick Baking Pan – I use this 9×13 pan for many recipes, brownies, fudge and blondies, the quality is great and it will last you a long time
  • Vanilla Extract – love this vanilla extract, the flavor is great, I always have some on hand
  • White Chocolate Chips – I use these all the time, they taste great in cookies and are perfect to melt with condensed milk

What a beautiful cakes! I love using olive oil to make cakes, and loving your zucchini-blueberry combo! I must try this!


Lora @savoringitaly

Such a great summer cake recipe! Love the pretty piping and that you used olive oil!! I have to make this for my kiddos this week!!


Anna @ Crunchy Creamy Sweet

I am loving the zucchini and blueberry combo! Wish I had a slice of this cake right now!



I am making this as we speak :) I can't wait to try it! The recipe calls for baking powder and salt, but those ingredients are left out of the directions :)



My white chocolate sauce came out very thick. I don't see it how it is possible to soak in and moisten the cake. Could I have done something wrong? At this point I don't know if frosting will be necessary it is so coated.


If the white chocolate is not very fresh, it takes way longer for it to melt. It may take up to 6 30 seconds attempts, mix well after each one and microwave in 30 seconds increments until its melted.

Obviously, with that list of ingredients it has to taste amazing. But nearly 700 calories for a piece that's probably 5 or 6 bites? I'm afraid I can't afford to have this in my house! :(


no, not 5-6 bites :) a large, good size slice :) and you can reduce the sugar in HALF when making the cake!



If I substitute a boxed cake mix, what can I leave out of the ingredients and directions? Thanks.


the eggs, box cake mix usually asks for water, eggs and oil. You can use olive oil, just use as much as the instructions on the box says, not as much as I do in here.

Could I use something else besides white chocolate, I am not a fan? Also how about whipped cream on the top before serving, would that work? Thanks


Yes, use any chocolate that you like, it will taste great. And the whipped cream on top will be delicious.

I am not fond of white chocolate anything else I can use? Also I would like whipped cream on top instead of the frosting is that possible. Thank you.
