Zucchini Cake with Lime Cream Cheese Frosting

Zucchini and Lime Cake

Zucchini is great for baking because it can add a whole lot of moisture to a baked good. It can show up in cakes and quickbreads, just as carrots can. It is often paired with chocolate and over time I’ve noticed why: green is not a color that blends into a cake that easily (nor is it one that you expect to see in a cake) and chocolate can easily disguise it. Zucchini doesn’t add much flavor to a cake – again, like carrots in a cake – so there really is no need to hide its color if you don’t mind it. I don’t mind it at all, and you can see plenty of zucchini in this Zucchini and Lime Cake with Lime Cream Cheese Frosting.

This sheet cake uses up a lot of zucchini. Depending on what size your squash are, you should be able to fit in about 4 or 5 of them – which is quite a feat during zucchini season! The cake is ultra-moist and tender, and while you can see all those little green flecks in the cake, the hint of lime flavor both in the cake and in the frosting makes you think of lime, not just of zucchini, when you see them. The cake uses melted butter and can be mixed up in one bowl.

I cooled my cake right in the pan and put the frosting in a nice, thick layer on top. The sweet cream cheese frosting goes amazingly well with the moist, not-too-sweet cake and everything is tied together with the lime. Be sure to use fresh lime juice in the frosting, as that is what will bring in the most dramatic source of lime flavor and you want it to be bright. This is a great cake for making at home and muching your way through on a lazy, end-of-summer weekend, but it is the kind of cake that would also be a big hit at a barbecue or potluck if you want to serve a crowd. And, just like carrot cake again, you can always tell yourself that you’re getting an extra serving of veggies when you reach for that second slice.

Zucchini Cake with Lime Cream Cheese Frosting

  1. I’ve been on a lime kick myself. I recently made your lime and coconut crumble bars. They were excellent!

  2. We love lime! Great frosting to this moist zucchini cake!

  14. Looks ok but honestly i’d love to see a banana zucchini bread recipe rathern than lime!!! Maybe even a low fat recipe

  15. Looks ok but honestly i want to see something like a banana zucchini bread recipe not lime!!! maybe even a lowfat one!!

  16. wat a wonderful site and wat an awesome recipe!

    I have a v gud zucchini bread recipe… my question is what is the difference between a zucchini bread recipe and zucchini cake recipe. All the ingredients are exactly the same.

  17. Another great recipe and flavor combination.!! i made several zucchini cakes before but this one is the best so far.. I was hesitant to use the cream cheese frosting since it has marshmallow cream but I made the cake with it eventually and it was a instant hit!! Lime zest makes it so refreshing.. my husband loved it!!!

  18. Wow, good thing this uses a massive amount of zucchini! This is the first year I started growing zucchini at home & it just erupted. I honestly don’t know where they come from anymore.

    I might try subbing oil for the butter. Or do half and half of each .. that applesauce amount looks like it could come perfectly from one of those applesauce cups! Good to keep in mind for when I go back to college ..

  19. Yatee: Remember you can freeze zucinni just like any other squash. Just cut it into chunks or half inch slices, put in boiling water for about 3 minutes. Be sure to have the cold bath ready before boiling the squash. The middle of the squash will turn bright green after 3 minutes or before. Quickly drain it and put it into the cold bath (water and lots of ice). Let it sit until cold. Drain well and freeze. We put on cookie sheet in freezer before bagging it does not lump together in the freezer bag, or have too much moisture for the sealer machine.
