This lemon lime zucchini cake recipe is a citrus lover’s dream! It combines fresh lemon and lime juice, zest, and marmalade to a triple dose of citrus flavor. And on top of that, it features a lemon lime cream cheese frosting – it’s heaven!
For more citrus deliciousness be sure to try our Lemon Coconut Muffins, Pink Grapefruit Muffins, Pink Grapefruit Pie, and Key Lime Pie!
Our garden yielded a ton of squash this Summer.  A ton.  And we’ve just harvested what is hopefully the last bunch.  Fingers crossed. That said, this overabundance of squash enabled/forced me to get creative in finding news ways of using it.  So as I dragged in the remaining squash I held up a yellow and a green zucchini squash and immediately came to mind was “lemon and lime.”  So I thought it would be fun to incorporate them both in to a cake along with lemon and lime.  And then to add lemon lime frosting on top of it all for a double dose of citrus!
The verdict: Â Sublime. Â I think you’ll agree.
More than anything though I just wanted to eat the entire bowl of lemon-lime cream cheese frosting! Â I didn’t. Â But I wanted to.
For fewer calories you can also leave off the frosting and just add a small sprinkling of powdered sugar. Â But for the “full effect” I highly recommend the frosting!
For the frosting you’ll need lemon-lime marmalade. Â Some stores carry it but you can also buy it online.
OR…you can make some yourself!  And once you make a batch of this amazing stuff it’ll keep stored for at least a year! There are so many delicious uses for lemon lime marmalade.  Check out my post for tons of ideas and the recipe: Lemon Lime Marmalade.
Lemon Lime Zucchini Cake Recipe
Let’s get started!
Combine the flour, baking soda, baking powder and salt in a bowl and set aside.
Ignore the picture on the bottom right. Â Seriously, my 3 and 5 year olds at the time were having a meltdown and, distracted, without thinking, I put everything in the bowl at once. Â What you want to do instead is….Cream the butter and sugar in a bowl until pale and fluffy. Â THEN add the eggs, vanilla extract, lemon and lime zest and beat until combined.
Stir in the grated squash. Â Then, alternating between the buttermilk and flour mixture, add each in thirds, stirring after each addition. Â Don’t over-stir or the batter will be dense. Â Stir just until combined, a few little lumps are okay.
Pour the batter into a buttered 8X8 inch cake pan. Â I use and LOVE Magic Line pans – made in the U.S.A. and professional quality.
Baked in a preheated oven at 350 degrees F for 30-35 minutes or until a toothpick inserted into the center of the cake comes out clean.
Make the Lemon Lime Cream Cheese Frosting
While the cake is baking make the frosting. Â Combine all the ingredients except for the powdered sugar in a mixing bowl and beat until combined.
Then add the powdered sugar and beat until combined and fluffy.
Your cake is ready! Â Let it cool completely.
You can stop right there and just enjoy it with a sprinkling of powdered sugar for fewer calories….BUT….
….I highly recommend taking it to the next level and and adding this luscious lemon-lime cream cheese frosting!
Spread that lemon-lime frosting on good and thick!
Enjoy!

I wonder if anyone still has zucchini at the farmer’s market…I’m going to look when I go down there in a little bit. This looks so yummy! And that frosting…I can never turn down cream cheese frosting but when you add in lemon-lime flavors, I am so there!

They still have zucchini at mine, I think you’re in luck, Michelle :)

That’ll work just as well, Michelle :) Happy baking!

Kimberly @ The Daring Gourmet says
Haha! I really shouldn’t be complaining about too much food, but when you’ve had a whole Summer of endless squash and your friends have had enough of taking it off your hands…yeah, it gets a little tiresome :) But, I refuse to waste it, so I’m still cookin’ and bakin’!
