My husband, Stacy has developed a love of baking and a reputation for being a good baker among our family and friends. 

Two of his most requested are this Key Lime Cake and his Strawberry Cake with Strawberry Buttercream Frosting.

Confession time! Stacy bakes the cakes and makes the frostings but he prefers me to frost and I usually frost them. I consider that to be the fun part. I love it because he’s usually cleaning up while I’m frosting the cake.

I shaved the peeling from fresh limes and used the shavings to decorate this Key Lime cake and then added a few fresh pecan halves. Living in Georgia where pecans are abundant, we put pecans in and on everything! 


  • Box lemon cake mix
  • 1 1/3 cup vegetable oil
  • 4 large eggs, beaten
  • 1 (3 oz.) pkg. lime gelatin
  • 3/4 cup orange juice

How to make Key Lime Cake

Step 1

Preheat the oven to 350. Grease and flour two round cake pans.

Step 2

In a large mixing bowl, blend together cake mix, oil, eggs, gelatin, and orange juice on medium speed until smooth and well blended.

Step 3

Pour the batter into your prepared cake pans.

Step 4

Bake according to box mix directions. The cake is done when a toothpick inserted into the middle comes out clean.

Allow the cake layers to cool completely before frosting.

  1. This Key Lime cake looked so good that I had to come back and comment on this cake too. I love Key Lime anything and can’t wait to try this. I’ve scheduled a facebook share. Thank you for sharing at Think Tank Thursday so I could find this recipe.

  2. What an amazing cake Shirley!!
    It’s kind of hard getting lime here, but I’d loveeeeeeeee to try this recipe.
    It looks and sounds super tasty

  3. Hi Shirley. How lovely of you to link your recipe up to Thriving on Thursdays last week. This looks so, so good and perfect for St Patrick’s Day. I can’t wait to try it. I’m featuring this one at tomorrow’s party. Hope to see you again.

  4. This cake is so pretty and sounds delicious! I love pecans, it must be so nice to have pecan orchards so close by. Thanks so much for sharing at What’d You Do This Weekend? I hope you will join us again next Monday!

  5. Wow!! Love this!! Thanks for sharing on My 2 Favorite Things on Thursday – Link Party!! Hope to see you tomorrow !! Love your stuff! Pinned!

  6. Sounds delicious! Do you know I have never eaten Key Lime Cake but I might try this recipe. Thanks for sharing on #AnythingGoes Link Up Party.

  7. This looks delicious and so does that strawberry cake, I don’t know which one to try first! I’ll take baking over cooking any day! But I agree, the decorating is the fun part.

  8. I grew up in a pecan orchard and my mom and dad still harvest lots of pecans (about every other year) and always freezes some for me. I have to say that GA pecans are the best!

    Limes are such a favorite of mine. I always get water and lime instead of lemon when dining out. That’s why I know I’d jump mouth first into that beautiful cake. I can almost taste it now. This will definitely be made at my house soon. It looks so yummy!

    1. I wish we had pecan trees in our yard! We do have some friends who give us pecans that we freeze. I’d put pecans in almost everything that I could and if pecans are not appropriate, then maybe onions would be! LoL Two of my favorite ingredients, both grown in GA. 🙂

  9. There you go again Shirley! Showing another one your husbands delicious cakes and making my mouth water. Lol. Sounds like a very easy recipe that I can definitely make. Love your day citations. Thanks for sharing!

    1. I think among Stacy’s cake recipes, this is one of the least trouble to make. It ranks at the top of the list of most requested and there is never leftovers.

  10. Shirley, this looks delicious. I love that it starts with a mix. That always makes baking easier and that’s my kind of baking! I would never have thought to use orange juice in the mix. I love key lime pie, so I’m going to give key lime cake a try. Pinning to remind myself to make this one!

    1. I know, right! I love scratch cakes too but this one is a lot less trouble and just as good as a scratch cake! My hubbby loves Key Lime pie too which is why he knew he would love the cake the first time he made it. Thanks so much Beverly.

We enjoying hearing from you!
