Key Lime Bars

by flavorthemoments on August 11, 2013


Key Lime Bars are a buttery, flakey crust topped with a deliciously sweet, citrusy key lime filling and powdered sugar.  The crust to filling ratio is perfect, they’re easy to make, and they’re a huge crowd pleaser!  You just can’t beat that.

I just got home from the Tahoe area, and I’ve got a bit of a traffic hangover.  It took 4 hours to get home, when it normally takes 2 1/2.  I have zero tolerance when it comes to bumper to bumper traffic. The only thing that kept me sane was my satellite radio, entertaining my ears with the likes of Nickelback, Pitbull, Justin Timberlake, and my girl P!nk.  Thank you, Siruis XM, and ROCK ON.   :smile:

While I was away, my new blog design was rolled out.  It’s still in progress, but it’s very exciting for me!  I went with Zesty Blog Consulting after months of fumbling around on my own trying to figure out how to do this and how to do that.  I guess I did pretty well considering I had no experience with blogging and was far from being social media savvy.  I decided I wanted to pay someone to deal with everything so that I could focus on the food, photography, and blogging end of things more.  I didn’t want to drop thousands of dollars (gulp!), and I found Zesty Blogs to be quite reasonable for everything that was included, and Cory is very knowledgeable and helpful.  Zesty Blogs does include a logo in the redesign price in the package that I selected, but I had already enlisted the help of my good friend Colleen at Dillon Designs, so she created my lovely logo for me.  Thank you, Colleen!  I appreciate your patience going back and forth, back and forth with me on the design.  You’re the best!   :grin:

Now that I got through some of that important business, let’s talk Key Lime Bars.  It’s no secret that I love, love, love key lime anything.  It doesn’t matter if it’s  Key Lime Pie with Meringue Whipped Cream, Coconut Key Lime Pie Smoothies, or my Fresh Key Lime Greek Yogurt Dip, it doesn’t get much better than key lime flavor for me.

I made these bars for my good friend that was visiting from Switzerland.  She always brings me Swiss chocolate, and I always make her lemon bars.  Yes, I said lemon.  This visit, I had fresh key lime juice in my fridge, so I asked her if I could use that instead of lemon.  She’d never had a key lime dessert before, so it was time to introduce her!  The funny thing is, the key lime flavor wasn’t very pronounced.  In fact, if I hadn’t have told anyone that they were key lime bars, they wouldn’t have known.  Next time, I may scale back on the sugar in the key lime filling by 1/4 cup and see if the key lime flavor comes through more.  These bars were perfect, however, so I’d completely be messing with perfection.  I just might have to leave them exactly as they are.  :wink:

Key Lime Bars

Key Lime Bars are a buttery, flakey crust topped with a deliciously sweet, citrusy key lime filling and powdered sugar. The crust to filling ratio is perfect, they're easy to make, and they're a huge crowd pleaser! You just can't beat that.



1 cup unsalted butter, softened

1/2 cup powdered sugar

2 cups all purpose flour

pinch of salt


4 large eggs, lightly beaten

2 cups granulated sugar

6 tablespoons all purpose flour

1/4 cup + 2 tablespoons key lime juice

1 tablespoon key lime zest

powdered sugar, for garnish


Preheat oven to 350 degrees. Spray a 9x13" baking pan generously with cooking spray.

Prepare the crust:

In a large bowl, beat the butter and 1/2 cup powdered sugar till light and fluffy, about 2-3 minutes. Add flour and salt, and beat on low speed until just incorporated, about 1 minute more. Press the dough evenly into the prepared pan and bake on the middle rack of the oven 20-25 minutes, or until lightly golden. Remove from the oven and cool on a wire rack.

Prepare the filling:

In a medium bowl, whisk the eggs and 2 cups of sugar. Add the flour and whisk until combined. Whisk in the lime juice and zest. Pour over the cooled crust, and bake 25 minutes longer, or until the filling has set. Cool completely on a wire rack. Dust with sifted powdered sugar once cooled, and cut into squares. Enjoy!


You can easily substitute the key lime juice with lemon or regular lime.

OMG…finally a recipe that does not contain sweetened condensed milk :) I love your new look, and it loads much faster. I can’t wait to see it when it’s all done!


flavorthemoments August 11, 2013 at 8:44 pm

Thanks, Lisa, except I mistakenly loaded lots of pictures in RAW format ions ago and now they’re all messed up. UGH! Lots of clean-up to do, needless to say.


Anne ~ Uni Homemaker August 11, 2013 at 10:15 pm

Love the new logo and design Marcie! Bummer you were stuck in traffic. Four hours is a really long drive when it should have been 2.5 –eek! On the upside, this Key Lime Bar is sublime! :) Have a great week.


flavorthemoments August 11, 2013 at 10:24 pm

Thank you, Anne! I’m horrible in traffic — too antsy! The key lime bars are definitely the bright side.


Linda | The Urban Mrs August 11, 2013 at 10:18 pm

Beautiful key lime pie! I know exactly how it feels being stuck in traffic and you just want to scream out loud. Love the new layout and of course the zesty recipe.


flavorthemoments August 11, 2013 at 10:26 pm

Thank you, Linda! I did want to scream out loud bit refrained. I just sang instead. My poor kids.

I love key lime everything! I tried to make key lime cheesecake a couple of days ago, but I added too much sugar too and the flavour didn’t come trough either :( These bars look amazing, I think I’ll try them reducing a bit the sugar… I love the tangyness from the limes!
And the blog’s new look is amazing, by the way. The new header is lovely! x


flavorthemoments August 12, 2013 at 7:50 am

Thank you, Consuelo! I didn’t think the bars were too sweet, but yes, in order for that flavor to come through more, the sugar has to be scaled back. Key lime cheesecake sounds amazing!


Jamie@Milk N Cookies August 12, 2013 at 2:59 am

These look scrumptious! My husband and I went to Key West on our honeymoon and had a blast. Anytime I see a key lime dessert, I get a little reminiscent of the fun times we had together (especially when I’m sitting in traffic and wishing I were doing anything other than commuting!). Perhaps I’ll have to make these for our first anniversary! Thanks for the inspiration.

I’m a new reader so I don’t think I ever got a chance to see your old layout — but I love the new look!


flavorthemoments August 12, 2013 at 7:55 am

Welcome, Jamie! Key West sounds amazing. I’ve never been there, but the key lime thing just happened with a recipe I tried for pie, and it became something I use often. I think the sugar needs to be scaled back about a 1/4 cup to taste the lime more. I’m going to experiment with that. They’re still absolutely delicious, however!


Christin@SpicySouthernKitchen August 12, 2013 at 4:53 am

We totally have the same taste in music! Key Lime Pie Bars look delicious. I must try them!


flavorthemoments August 12, 2013 at 8:26 am

I couldn’t survive the car ride without the music! I hope you get to try these, Christin!


Ashley August 12, 2013 at 6:14 am

I have absolutely zero patience for traffic either …. it makes me so cranky. Thankfully we’re no longer in DC and don’t have to deal with it anywhere near as much now! haha These bars sound awesome – I totally want to eat that crust!


flavorthemoments August 12, 2013 at 8:23 am

Glad you got out of that DC traffic, Ashley. I commuted to SF for 11 years, and luckily I could take the train or I would’ve never made it! The crust on these bars was amazing!


Ash-foodfashionparty August 12, 2013 at 12:31 pm

Loving the look of your blog and yes of course the bars are delicious looking too. Getting stuck in traffic is not fun at all…


flavorthemoments August 12, 2013 at 12:45 pm

Thank you, Ash. The bars were much more fun than the traffic…obviously! :)


Paula August 12, 2013 at 2:07 pm

These look SO good, I bet I could eat the whole pan, I know this because I did eat all but two the last time I made bars similiar to this :)


flavorthemoments August 12, 2013 at 2:33 pm

Maybe you ate the whole pan, but I’ll bet you ran it off afterward, didn’t you? Lol. Luckily I gave a lot away, or I may have done the same!


Meghan @ Spoonful of Flour August 12, 2013 at 4:18 pm

I know how you feel, I definitely sat in bumper to bumper traffic this weekend too. These Key Lime Bars look so good!


flavorthemoments August 12, 2013 at 7:17 pm

Traffic is inevitable, I suppose. I needed some of these key lime bars for the car ride!


Jackie l Food.Wine.Fashion August 12, 2013 at 5:27 pm

The new website looks great Marcie! I love that picture of you – you look fabulous :)

Lemon bars are one of my favorites and I’m a big fan of key lime so this would probably end up being one of my favorite desserts EVER.

xo Jackie


flavorthemoments August 12, 2013 at 7:10 pm

Thanks, Jackie! That picture of me is WAY too big. I’m getting that shrunk down quick! My friend that LOVES lemon bars was crazy about these, so I bet you will be, too.


Liz August 12, 2013 at 6:42 pm

LOVE all things lime!!! I could eat up the whole pan right now and I bet you wished you had some on your long trip home! Love your new blog design BTW! So pretty :)


flavorthemoments August 12, 2013 at 7:23 pm

Thank you, Liz! I definitely needed some for the car ride!

Ugh. Traffic. Love the new blog design, by the way. It’s lovely! As are these bars. I am in love with anything key lime.


flavorthemoments August 15, 2013 at 6:26 pm

Thanks, Nicole! Still working out a few kinks on the design, but so far so good. Sounds like we agree on the key lime thing!


Karly August 18, 2013 at 6:28 pm

Key Lime Bars are the perfect summer treat! Thanks for linking them up with What’s Cookin’ Wednesday!
