I have been baking since the time I could climb up on a stool and help my Mom in the kitchen. Baking cakes and cookies for my friends and family have always been my favorite thing to bake! I shared how my kids get to choose the flavor of their birthday cake every year and they get pretty creative! Since my daughter, Sadie, is obsessed with anything lime flavored, I knew this had to be her special birthday cake.

This is literally one of my husband’s favorite cakes I have ever made. It is seriously the best lime cake!

We just returned home from a Caribbean cruise with the family and had the best time! It was so nice to be away from cellphones and laptops and reconnects as a family.  My kids felt like Kings and Queens with access to unlimited food and drinks! Our favorite virgin non-alcoholic drink was definitely the mojito — made with fresh lime juice and mint. This drink was definitely the inspiration for this fresh key lime cake!

This Key Lime Cake with Cream Cheese Frosting can be made as a layered cake with two 9-inch cake pans or three 8-inch cake pans or in a 9 x 13 pan.

How to make the Best Key Lime Cake (the best tips and tricks):

  1. Whip oil, eggs, whole milk, lime juice, and lemon zest for about 2-3 minutes.  I would highly suggest using FRESH lime juice for this cake. It makes such a difference in the flavor. Also, zest the limes first before juicing since it is much easier to zest while the limes are hard and round.
  2. Fold in dry ingredients. Pour into greased cake pans. It is so important to grease the cake pans well so the cakes easily come out of the pans. You can choose to use two 9-inch cake pans or three 8-inch cake pans, depending on preference. If you use three 8-inch pans, the layers will be thinner and will need less baking time. This can also be made in a 9 x 13 pan.
  3. After cakes have baked, set aside to cool. Make frosting by whipping softened cream cheese and butter for 4 minutes until light and fluffy. This makes the frosting extra light.  Add powdered sugar and whip for 1 minute.  If you want a stiffer frosting, add more powdered sugar.  Fold in lime juice and lime zest.
  4. Remove cakes from pan. Spread frosting on top of one cooled cake layer. Place the other cooled cake layer on top and spread frosting all over. I use this angled spatula to spread frosting all over the cake layers. Garnish with freshly sliced limes.

    End product tasted really good. Had a thicker “crust” to the cake and was challenging to get out of the pan despite oiling and flouring pan. Batter was very thin, despite adding 2 Tbsp flour to it. Took about 75 minutes to back. Slight lime flavor, so add some more zest if you’d like it more lime flavored. Would make again and make a few adjustments 🙂

    Your Key Lime Cake recipe sounds really delicious and I’m going to make this. I’m curious as to the steps that you listed. I’m seeing these changes among the younger folks recipes. Very interesting to me.

  3. We followed this recipe, word for word, and put the dough into cupcakes, they cake out sunken and doughy, even after adding an extra 10 minutes. The dough itself seemed Very slick and too runny.
    I don’t know if the flour called for is too little or What but this did Not turn into cake texture At All.

  4. 5 stars
    Amazing recipe. Question- why are you calling this a key lime cake but the video is not showing key limes and the recipe doesn’t specify key limes?

    I used key limes and this was amazing!
