Lemon Blueberry Cake

This cake is seriously amazing. The combination of lemons and blueberry is timeless, and adding in zucchini (courgettes)is the BEST way to add moisture! I used whole fresh blueberries in the cake and then added copious amounts of lemon flavor and zest to the cake and frosting. I think you will find that this cake is just plain perfect. Try my Lemon Blueberry Sweet Rolls for more of this timeless combination.

Zucchini in Baking

Some folks wonder why do I use zucchini in baking? First off, I love zucchini. It works amazing as a savory side or incorporated into desserts. No, you cannot taste the zucchini itself when you are baking, but you do reap the benefits of this vegetable that is packed with moisture.

I found this recipe over at allrecipes.com and it is officially labeled as Blueberry Zucchini Bread.  I studied the ingredients and thought, there is no way I can pass this off as bread!  Why not just make it in an 8-inch round cake pan and see how it goes.

It went. Right into my belly.

Lemon Blueberry Cake with Lemon Buttercream


This cake is moist!  Like amazingly so.  I popped my cake into the freezer right after baking only because I wanted a nice clean cut.  But I do recommend eating when it is still warm and the zucchini bits are lounging around the bursting blueberries in a delightful way.

Because this recipe is technically designed as a bread, this cake is pretty dense.  Densely packed with deliciousness that is. 😉

I would really love to try this cake with raspberries, as my love for blueberries has inadvertently excluded all other fruit on my little baking blog.  Maybe even a berry medley!  Oh yeah.  Definitely.

Off to bake!

Course: Dessert
Cuisine: American
Keyword: Lemon Blueberry Zucchini Cake
Servings: 8
Author: Amanda Rettke
  • 2 cups finely shredded and lightly drained zucchini
  • 3 large eggs, lightly beaten, room temperature
  • 1 cup (224g) vegetable oil
  • 3 teaspoons vanilla extract
  • cups (450g) granulated sugar
  • 3 cups (375g) all-purpose flour
  • 1 teaspoon kosher salt
  • 1 teaspoon baking powder
  • ¼ teaspoon baking soda
  • 1 pint fresh blueberries, you can reserve a few for garnish if so desired
Lemon Buttercream
  • 1 cup (226g) butter, room temperature
  • cups confectioners' sugar
  • juice of one lemon
  • zest of one lemon
  • 1 teaspoon vanilla extract
  • teaspoon kosher salt
  1. Preheat oven to 350°F. Prepare two 8-inch round cake pans with butter and flour or use non-stick baking spray.
  2. Grate a large zucchini (or two small zucchini) and place in a clean dish towel. Life the edges of the towel up and squeeze some of the extra moisture out, but you do not want the zucchini to be dry. You will want 2 total cups of shredded zucchini after it has been drained. Set aside.

  3. In a large bowl and using a hand mixer, beat together the eggs, oil, vanilla, and sugar. Fold in the zucchini.
  4. Slowly stir in the flour, salt, baking powder, and baking soda. Gently fold in the blueberries. Divide batter evenly between prepared cake pans.

  5. Bake 35-40 minutes in the preheated oven, or until a knife inserted in the center of a cake comes out clean. Cool 20 minutes in pans, then turn out onto wire racks to cool completely.
Lemon Buttercream
  1. Combine butter, sugar and salt and beat till well combined.
  2. Add lemon juice and vanilla and continue to beat for another 3 to 5 minute or until creamy.
  3. Fold in zest (If you are piping this buttercream, I recommend leaving out the zest).

    Absolutely amazing!

  • Ellie says:

    I am going to try this cake. I am wondering why it is called lemon cake when there is no lemon in the cake part of the recipe. Having vanilla in cake recipe makes it vanilla cake unless you switch out the vanilla for lemon.

    • Elizabeth Keeney says:

      I work with iambaker and am happy to help out with questions!
      Hi, Ellie! The lemon flavor is the lemon zest and juice in the lemon buttercream. Enjoy!

  • Marilyn says:

    Could you bake this cake in a 9 x 13 pan, if yes what temperature and for how long? Can you substitute frozen berries too?

    • Elizabeth Keeney says:

      Hi, Marilyn! I work with iambaker and am happy to help with questions. We have not tried baking this cake in a 9×13-inch pan, but you may not have enough batter for that size pan; an 11×7-inch baking dish would be closer in volume. In addition, we have only used fresh blueberries in the recipe. Have a great day!

  • Valerie says:

    Fabulous cake. Big hit. I did have to add a good 20 minutes to the baking time. (my oven is caliberated). Also, I used organic, store bought, blueberries which were virtually tasteless, sadley. However, they did add a nice tart zing to the cake. Fresh home-grown blueberries would put this cake over the top!

  • Arland Coleman says:

    Could I bake this in a burnt pan instead as I don’t haArve the round pans?

  • Becky says:

    This cake is delicious! Perfect for spring/summer! I followed the recipe exactly, except I used 4 small 5” cake pans so that I could make 2 mini cakes (one to share :)). Just turned the temp down for baking and added about 15 minutes. Will definitely be making this again, thanks for sharing!

  • Patricia says:

    Wonderful cake and buttercream icing. Delicious & beautiful. Thank you!

  • Imogen Stebbings says:

    Hi! Should I fold in the flour or use the whisk?

    • Elizabeth Keeney says:

      Hi, Imogen! I work with iambaker and am happy to help with questions. You can gently stir in the flour. I hope this helps, and have a great day!

  • Rita says:

    Can you make the cake,
    LemOn and blueberry without the zucchini

  • Rebeca says:

    I love this cake! Is my second time baking it and I’m in love of this recipe ☺

  • Janice says:

    Do you have a recipe for a lemon cream cheese frosting instead of buttercream??

  • Lori Gravley says:

    This is a new favorite cake. Thank you for the recipe!

  • Christine says:

    I made your recipe for the Zucchini Blueberry cake and it turned out delicious! I brought it to a friends house and it was a big hit.
    Thank you for sharing your recipe.

  • saim smith says:

    I’ve always made it in two round cake pans. Could this cake be made in a bundt pan? Maybe it would need to have a portion of batter placed in another small pan to properly distribute?

    • Elizabeth Keeney says:

      Hi, saim! I work with iambaker and am happy to help with questions. We have not made this cake in a bundt pan, but you sure could try it! Let us know how it turns out, and have a great day!

  • Cathy Kloster says:

    I made this cake yesterday! Turned out beautifully. The frosting is fabulous. My husband tells me he’s not a fan of zucchini. However, he absolutely loves this cake.
    Thanks for posting this wonderful recipe!

  • Karen says:

    Oh my! Just baked this in a 9×13 app.35 minutes.. It is half gone! This is a keeper. I used golden zucchini, non peeled, and it looks like lemon peel in it…

  • Leora says:

    Wonderful flavors. My only caveat is that with 3 C. flour and 2 C. of zucchini, this isn’t going to fit in 8″ cake pans I used 9″ which was much more accommodating.

  • Sharon says:

    Amazing!!!! Everything I make of yours has been 🙌🏻🙌🏻. Thank you!!

  • yvonne says:

    Do you peel the zucchini?

    • Amanda Rettke says:

      You can! I have made it both ways and prefer to leave the skins on, but sometimes peel if I don’t want to give away my baking secrets. 🙂

  • Mary says:

    How much lemon juice in the buttercream?

    • Elizabeth Keeney says:

      Hi, Mary! I work with iambaker and am happy to help with questions. Use the juice of one lemon for the buttercream. Have a great day!

  • Bobbi says:

    Great cake. But I’d like to make this for our coffee group. What changes do you make for bread or loaf cake?

  • Jean says:

    I found the recipe using 1/2 cup butter and 8 ounces cream cheese. Yummy. Every thing tastes better with cream cheese.

  • Jill Lampson says:

    I have gotten great reviews when I’ve made this. Can this be made into cupcakes?

    • Elizabeth Keeney says:

      Hi, Jill! I work with iambaker and am happy to help with questions. I would recommend these Lemon Blueberry Cupcakes. Have a great day!

  • Beth Drotar says:

    I made this cake and it got raving reviews from all who ate it!! Worth the effort of baking it!! <3 it!!

  • Jane Bennett says:

    I’m looking to bake this cake, but I’m confused about the lime. In your introduction you say “ added copious amounts of lemon flavor and zest to the cake and frosting”, but there is no mention of added lime in the cake ingredients or in the instructions. Please can you advise.
