Key Lime Cake with Key Lime Cream Cheese Frosting
Citrus makes me think of Spring. This cake makes a great springtime dessert. St Patrick’s Day, Easter, and Mother’s Day would be the ideal time to enjoy this cake.
One of my favorite things to do is take an extensive recipe and make it easier to prepare. (You know how impatient I am!) I would love to spend hours in the kitchen baking and decorating cakes, prepping and preparing beautiful meals. But, the truth is, I just don’t have that kind of time. My boys have activities and need help with homework and such. I did implement a chore systemย for them to follow this summer,ย but they still need supervision.ย Therefore, for now,ย it’s simple, easy, and quick dishes!! (Mostly)
Tips and Method
This recipe was inspired by Trisha Yearwood’s Key Lime Cake, but I made it easier! I started with a cake mix with additions that make it taste homemade. The Key Lime

Cake mix and gelatin.

Pour the oil into the mixing bowl.

Then add the eggs and mix on high speed to combine.

I got excited and didn’t take pix of adding the orange juice, lime juice, and vanilla extract.

Pour the batter into the pan, then bake until the cake sets. You’ll know it’s baked when a toothpick inserted in the center comes out clean, or with a few moist crumbs.

I was planning to give the key lime cake away, so I baked it in a disposable aluminum pan.

When I originally made this lime cake for my site, I made at in a 9×13-inch aluminum pan. I made it again for a celebration and made three 8-inch round layers. For both cakes, I topped them with a Key Lime

This looks and sounds sooo appealing! Thanks so much for sharing at Weekend Potluck. Love your awesome recipes.
Thank you so much, I truly love to bake. Wish my family could live off desserts! ๐
I like to add milk to make cake mixes for extra moisture. Do you think I could use milk instead of the orange juice?I’m looking so forward to trying this as lime is one of my favourite flavours!
Milk would prob be ok, but it won’t have as strong citrus flavor using the milk.
I LOVE anything key lime! This cake would make a great St. Pat’s cake too. So fun! BTW, I host a link party every Wednesday night and would love if you stopped by sometime. Have a great rest of the week!
