Blackberry Lime Cake

Decadent blackberry cake with rich buttercream frosting and hints of lime throughout each bite. 

This cake and I, we have a love-hate relationship.

Love because it’s crazy delicious. Hate because it almost sent me to the looney house.

What you’re seeing in these photographs is a revised round two version of the cake I tried to make Saturday night. A cake that failed miserably and had me on the verge of pulling my hair out and calling it quits with cake-baking.


The first of the cake problems came when I had just begun mixing the dry ingredients. I stopped mid-baking soda scoop to answer the phone and then had to go move the car to another position in the garage for my husband to be able to park the other car (Mazda #2) closest to his tools.

Thinking that I’d only be a minute, I didn’t bother to grab shoes.

In retrospect I really wish I’d grabbed a pair of flip flops.

Immediately after moving the car, I hurried to get back inside to resume my cake baking adventure. While walking through the garage however, I stepped on a piece of glass (from the freaky flying-tire accident I told you about in this post ).

After managing to pull it out of my foot, I left a lovely little trail of only right-sided foot prints all the way across the concrete floor.

After a quick bandage job, I was back in the kitchen. But it wasn’t until after I’d added both the baking powder and the baking soda that I realized that in the whole car-moving bloody-foot fiasco I’d mixed up the measurements for the two agents. I  now had twice as much baking soda as I needed sitting on top of my flour.

So the genius inside of me though, oh I’ll just scoop half of that out and proceed as though it never happened. . .

Stop shaking your head, it gets better.

After an intermission where the husband and I went out for dinner, I got back to the making of the disaster cake. I whipped up the rest of the batter, filled the pans, and stuck the pans in the oven.


(Five minutes later…)

Wait, is that a third of the flour mixture I see still in the bowl?

Oh dear.

Yep, I really did what you think I did.

I pulled the pans out, dumped the contents back into the bowl, stirred in the remaining flour mixture, refilled the pans, and put them back in the oven.

I just don’t know when to stop I guess.

I soon realized however that my pans were too full. The batter was going to spill over. Ah hah! I’ll just place this piece of tin foil on the next rack down so that the spilled batter will land on the foil instead of the rack and coils. Then the rest of the cake will bake perfectly and life will be bliss.


After a few minutes of watching anxiously as a disaster occurred in my oven, I threw in the towel.


After sending the husband on a 911 emergency ingredient and cake pan run to the store, (and after much of his coaxing), I decided I’d better leave round two of the cake for the next morning.

Thankfully round two turned out quite lovely and extremely delicious. Enough to make the night before worth the nightmare.

I officially made my first-ever successful cake. We’re just full of firsts around here. And full of embarrassing stories to go with them.

Oh well, chalk it up and move on right? Or chalk it up and eat some cake.

Yeah I like that better.

  • 3 cups cake flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1 teaspoon salt
  • 1 cup butter
  • 3 cups sugar
  • 5 eggs
  • 1/4 cup lime juice (about 2 limes)
  • zest of 1 lime
  • 1 teaspoon vanilla
  • 3/4 cup buttermilk


  • 1 cup heavy cream
  • 4 tablespoons brown sugar
  • 1/2 teaspoon vanilla
  • 2 cups blackberries, divided


  1. Preheat oven to 350 degrees. Lightly spray 2 9-inch round cake pans with cooking oil. Sprinkle with flour and tap out excess. In a medium bowl combine flour, baking soda, baking powder, and salt.

  2. In a large bowl, cream butter and sugar until light and fluffy. Add eggs one at a time, mixing well between eggs. Stir in vanilla. Add about 1/3 of the flour mixture. Add lime juice and zest and mix well. Add half of the remaining flour mixture and buttermilk until incorporated. Add remaining flour mixture and mix well. 

  3. Pour batter into prepared pans and bake 20-30 minutes, until and inserted toothpick comes out clean and cake springs back when touched. Allow to cool on wire racks. Loosen edges with a knife and invert cakes on a flat clean surface. 

  4. For the frosting, whip cream and brown sugar until stiff peaks form. Stir in vanilla. Mash one cup of blackberries with a fork and mix into cream. Spread 1/3 of the frosting onto the top of one cake layer. Carefully place other cake on top. Use a rubber spatula to spread remaining frosting completely over the entire cake, coating top and sides well. Top with whole blackberries. Refrigerate until ready to serve.

I’m so sorry you had such a tough time with this cake! I guess we all have days like that. It’s great you rebounded and made it again with great success. It looks fantastic!

    We definitely do have days like that. Fortunately it’s always worth it if we come out of it with a good story and having gained a little extra experience right? Thanks Laura!

Oh my gosh. That sounds like such a disaster! (But I would have done exactly the same thing, probably. xD especially with taking the baking soda out of the mixture.)
This cake is gorgeous, though! Such a gorgeous color. I might just have to make a bowl of that beautiful frosting and eat it. With a spoon.
Pinning this!

    Okay so it’s not just me who momentarily disconnects from my brain and does something as crazy as mixing up my baking soda and powder. 🙂 The frosting was so light and delicious, I honestly did eat it straight from the bowl with a spoon. 🙂 Thanks Abbie!

I had this exact day yesterday with some awful frosting on passion fruit cupcakes. I threw in the towel for good and made different cupcakes.

This looks amazing.. so glad you made it! I stepped in glass whilst photographing lollipops for my shop the other day.. it looked like a murder scene!

    So glad to hear it’s not just me who has disasters in the kitchen! I’m sorry about your glass-injury, I feel your pain! literally 🙂

I bet a slice of this cake was the best reward for all the misfortune you had the previous day. I recently made a cake with blackberries and lime, the combination was delicious.

    Thankfully it really was completely worth it when the final product came out as great as it did! Thanks Laura!

Glad you mustered up the energy to retry your cake…it turned out lovely! And the combination of ingredients sounds wonderful. Can’t wait to try this! Hopping over from Show Stopper Saturday to say thanks for the recipe. 🙂

Hi Tiffany!
Oh my heavens! This cake looks (and sounds) incredible!
I’m a BIG blackberry fan, so this cake is a must try!
Thanks so much for sharing.
Have a beautiful weekend,

I found this recipe a year and half ago and have since made this recipe at least 6 times. It is my go-to for every occasion. I’ve even made it into beautiful cupcakes for a baby shower. It’s fluffy, refreshing, and just the right amount of sweetness. I never write comments but felt like I had to because this never fails to impress family and friends. Thanks!!

I was wondering why a maximum of 12 hours in the fridge?

It looks like the frosting is full of seeds.Did it make the cake crunchy?

    Hi Shannon- it does have some seeds in it but I don’t feel as though it causes as texture issues!

could this be done as a sheet cake also in a 9×13 pan? I w I want to bring this to a potluck and in a pan would be easier than a layer cake for that purpose.

    Hey Tricia! I haven’t tested it so I can’t vouch for it, but it should work!
