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 amazinglyย as a savory side or is incorporated into desserts. No, you cannot taste the zucchini itself when you are baking, but you do reap the benefitsย of this vegetableย that is packed with moisture.

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.

Can I Use Frozen Blueberries?

Yes, you can! I do recommend allowing them to thaw first. The cake may also be tinted more of a blueish color as the thawed blueberries will bleed a bit more.

Can I Make this Into Bread?

Absolutely. Pour batter into 4 mini loaf pans and bake at 350ยฐF for about 50 minutes or until an inserted toothpick is removed with crumbs, but no wet batter.

Ingredients

Cake

  • 2 cups finely shredded and lightly drained zucchini
  • 3 large eggs, lightly beaten, room temperature
  • 1 cup (224g) vegetable oil
  • 3 teaspoons vanilla extract
  • 2ยผ cups (450g) granulated sugar
  • 3 cups (375g) all-purpose flour
  • 1 teaspoon kosher salt
  • 1 teaspoon baking powder
  • ยผ 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
  • 3ยฝ cups confectioners' sugar
  • juice of one lemon
  • zest of one lemon
  • 1 teaspoon vanilla extract
  • โ…› teaspoon kosher salt

Instructions

Cake

  • Preheat oven to 350ยฐF. Prepare two 8-inch round cake pans with butter and flour or use non-stick baking spray.
  • 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.
  • In a large bowl and using a hand mixer, beat together the eggs, oil, vanilla, and sugar. Fold in the zucchini.
  • Slowly stir in the flour, salt, baking powder, and baking soda. Gently fold in the blueberries. Divide batter evenly between prepared cake pans.
  • 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

  • Combine butter, sugar and salt and beat until well combined.
  • Add lemon juice and vanilla and continue to beat for another 3 to 5 minute or until creamy.
  • Fold in zest (If you are piping this buttercream, I recommend leaving out the zest).

  1. I made this cake for Mother’s Day and it was absolutely delicious!!! I LOVED the lemony frosting!! This recipe is a keeper!!! Everyone loved it!!!

  2. I have made this as both a cupcake recipe and a 9×13 recipe – for cupcakes I start checking at about 16-17 minutes, and usually take about 20-22 minutes. 9×13 cake takes about 30-40 minutes (my oven is finicky so I always start checking really early in the process). This is one of my favorite cakes, and the one that everyone asks me to make – in fact, I made it for my best friendโ€™s wedding!!!

  3. Your recipes look absolutely delicious! Great photos! Printed 2 and can not wait to try them! Question: As I am not a fan of vegetable oil, can butter be substituted? I may not have read all the text—oops! I printed the Perfect Choc Cake and Lemon Blue Zuc Cake. Please advise! Thank you! PS. Love the videos! One look is all I need to replicate! Awesome!

  4. Yummy, I used Huckleberries and the second time I make it I added lemon zest to the frosting. I made it in a 9*13, it turned out great, I also put it in the freezer for later and it turned out fine

  5. My previous comment, I meant to say I put zest into the cake batter mix to give it a more lemon flavor

  6. Thank you for sharing this amazing recipe. Its delicious!! Even my husband who only eats chocolate cake said it was amazing!! Definitely worth the time!!
