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When I originally made this lime cake for my site, I made at in a 9×13-inch aluminum pan.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

On your ingredient list it calls for 1/2 cup oil But on your instructions, you say put one cup oil? Does this recipe call for 1/2 cup or one cup oil?
Sorry about that! 1/2 cup is correct

Hey Paula. I tried this recipe twice, it was delicious. My concern is the cake would look very condensed like it fell. Itโs not like the typical cake height and lightness. Itโs heavier. I made it in a 9x13in pan.
This recipe was written when cake mix was in a larger box. 18.25oz – now they’re 15.25. I changed the recipe, but reduce that oil down to 1/2 cup. That’s the only change. The cake will definitely be lighter/fluffier now.
Hi i was wondering what i can do to incorporate some sort of graham cracker crust or any sort of graham cracker component? Thanks! Please reply fast my moms birthday is in 2 days, i am making this tommorow.
The only way I can think of is to sprinkle crushed graham crackers on top of the icing.
