Love key lime! Looks yummy!!!!!!!
Looks so delicious! I love the vibrant colour – so pretty 🙂
I made the Easy Key Lime cake and it was scrumptious!!
It was my first PMc recipe to make and it surely won’t be the last..
Can hardly wait to try others!! Hotty toddy!
Yayy!! oh, that’s one of my favorite, that one and the Easy Strawberry Cake. I’m so glad you liked it. Hotty Toddy… just 45(or so) more days! 🙂
I think I would substitute out the orange juice as would rather have a pure lime flavor. Wondering if I could just use water with possible addition of True Lime packets (crystalized real lime juice)? That is what I always use to replace lemon, lime, and orange juice. Only buy them when I need rind.
I’m not familiar with those lime packets, but if you’ve used them in the past they’ll probably work. I can’t get a handle on the all lime, but I’m sure it would work.
This looks and sound delish; not to mention extremely easy!
So easy, sometimes, I just want a simple dessert 🙂 do you ever feel that way?
Dear Paula, This sounds wonderful. I love Key Lime Pie, so I know I would enjoy this cake. Blessings, Catherine
Thank you,Catherine. It’s really good, I like anything with cream cheese frosting! 🙂 I actually like this cake better than a pie. Thanks for stopping by.
This cake is gorgeous, Paula! 🙂 LOVE the updated photos! I am willing warmer weather to get here fast with this cake!
i love the color. this is great for st. patty’s day. i also love lime!
I thought it would be a fun St Patty’s day dessert too! I love lemon and lime desserts, makes me think of Spring.
I adore key lime, Paula….it reminds me of my honeymoon! This cake looks incredible and I love your photos of it. Thanks so much for sharing at Saturday Night Fever!!
This looks delicious.

Thank you! I really like it.
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!
Thanks so much, Ginger, for stopping by and the invitation. I’ll put your party on my list!
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.
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! 🙂
I’ve made this twice. Once with your frosting (delicious) and once with just a whipped fluffy white frosting. Both ways are yummy! Thanks for a great recipe, I’ve shared it with so many!

Stopping by from Cast Party and these looks so yummy!
This cake tastes amazing!
I made this cake for my dad’s birthday and everyone in my family loved it.
I would suggest making this.
Thank you so much for letting me know Emily!!! I’m so glad your family loved it!
Just finished making this, whipped up super fast, tastes heavenly! Used juice of one orange mixed with fresh lime juice to make up the 3/4 cup of orange juice called for. Also added lime zest to the frosting. Thanks for sharing, going in the ‘keeper’ file!
Awesome! I’m so glad you like it and I love your changes!
This cake is so deliciously moist! I have added 7-Up instead of orange juice. When I make the icing, I squeeze the limes to get extra pulp in there. It gives it an added tangy-ness! One of our favorite cakes!
Yummo! Thanks for the recipe.
Hi Paula,
I cant get the lime gelatine here, in my country.
Is there any subtitute for this?
thank you..:)
I don’t know of a substitute, it’s the made ingredient that gives it the lime flavor
Hello Paula,
Me and the kids tried baking this cake. The icing came out great but the cake not so great.. I greased my 9 by 13 baking aluminum cake pan, but I ended up burning the cake, I don’t know what happened 🙁
Awe, I’m so sorry. Have you calibrated your oven. A lot of time the oven temp can be way off from what it’s set at, this sounds like what may have happened. You can get an oven thermometer from Walmart and test it. set the oven to 350 and when the oven says it’s at that temp check to see what the thermometer says, the themometer will be correct.
Thanks I will defiantly purchase one and retry.
Very good! May add a touch more of lime to the icing but it is very yum just like it is!!! Thanks 🙂
DELICIOUS!!!!! What I also did in effort to lighten it up, I used 2 small sugar free lime gelatin boxes and instead of cream cheese frosting I put on a dollop of SF Cool Whip!!!! Light and refreshing !!!! Thanks for the recipie!
I have this cake in the oven now. Smells wonderful, however two 8 inch round pans are taking much longer than the 25 minutes it says. Make sure you allow more baking time.
Definitely if u just used 2 – 8 inch pans it will take longer. I used 3 -8 inch pans.
My husband and I love key Lime pie. When I saw this for cake. I told him. We both agreed to make and try for Thanksgiving. Very very yummie! Can’t wait to make it for family when we return home.
I made this for my sisters birthday and it turned out so goooood! But I made it all from scratch since I didn’t have a cake mix on hand. I combined a white cake with this one and luckily it turned out so yummy and moist 🙂 Thank you for the recipe!
Just made this for a St. Patrick’s Day get together. It was a huge hit! It is a delicious cake. I used fresh lime juice in the icing it’s amazing. Thanks!
I made this cake ,it was so good,I couldn’t stop eating and the frosting is so good,it makes me think I can really bake,it,s addictive.Thanks for that great “made easy” recipe.I,ll try the strawberry cake next ,but for now I’m hooked on keylime.
