Taste of the Tropics in a Bar:
Key Lime “Brownie” Bars for Cinco de Mayo

Friends, once again, get your pucker on! This time around, it’s for some serious Key Lime action for Cinco de Mayo and summer. You knew this was coming, right?

As many of you know, I just adore citrus of any kind. I mean, even my favorite cocktail in the universe is the classic Margarita and its several incarnations. Yes, I capitalize the word Margarita. It’s out of respect. 😉

Thus far, I have featured three (3) Margarita cocktail recipes here on the blog: Coconut Ginger Lime Margarita with a killer coconut-ginger agave simple syrup kicked up savory-style with the addition of whole black peppercorns for a little heat. This cocktail tastes like it was barbecued, with a little smokey-heat, just perfect for lovers of BBQ. Sparkling Tart Cherry Margarita bursting with tart cherry flavor is my favorite summertime “girly” Margarita. And, Sparkling Apple Cider Margarita with a serious punch of apple cider and spices is my favorite Margarita in the Fall. As you would guess, there will be more Margarita cocktail action coming soon.

By the way, did you know there is a lime shortage this year? It’s true. Have mercy. I had a hard time finding them in my local markets, but scored big time with a few bags of these little wondersKey Limes. As you can see, we’re getting ready early for Cinco de Mayo. 😉 So, be sure to stock up when you find them for the holiday!

Meanwhile, when it comes to citrus, Key Limes (capitalized as well out of respect, ha!) are my ultimate favorite fruit. Y’all, I make a wicked Key Lime Pie that I am just itchin’ to share with you and the second “cheesecake cake” I ever made was a truly wicked Key Lime Margarita Cheesecake Cake. This cake was inspired by my husband, The Big Lug, and featured last spring in my post entitled, “On Love, Gratitude and Margaritas”.

As I shared in my last post featuring Best Ever Lemon Brownie Bars, I have an out of control Lemon Love board over at Pinterest. In fact, I love citrus so much that I just started a brand new board, Luscious Lime, for lime and Key Lime recipes starting with this one. Citrus is truly sublime and I cannot get enough of it. In fact, as I mentioned previously, each morning I enjoy a warm mug of lemon water sweetened with stevia before breakfast. But, my reasons and the health benefits for doing so are for another post. 🙂

In my post featuring Best Ever Lemon Brownie Bars, I mentioned that I had baked the original recipe first, but I couldn’t resist tinkering with it. What I meant was, not only did I tinker with it, I also made this version for Key Lime Brownie Bars. Just for you. You just didn’t know it yet. 🙂 Then, as you know, I simply could not resist baking these incredible bars with C4C (Cup 4 Cup Gluten Free Flour) to once again put the proverbial “rubber to the road” in a recipe test. Once again, this spectacular gluten free flour blend did not let me down. In fact, in this particular recipe, C4C performed flawlessly. No one, and I mean no one, will know these bars are gluten free! That’s a bona fide promise.

Just take a gander at that moist Key Lime Brownie Cake and luscious Key Lime Glaze…

As I mentioned in my last post, Lemon Brownie Bars or Key Lime Brownie Bars seems like a strange name for these sunny citrus bars due to the word “brownie” which conjures up thoughts of decadent chocolate bars. However, I believe the word “brownie” is fittingespecially considering the texture. We’re talkin’ brownie texture in this sublime bar. I have to say, these citrus bars are the most magical bars I have ever baked. Ever. I was truly amazed that this simple recipe, with so few ingredients, could impress me as much as it did. These Key Lime Brownie Bars taste phenomenal and are extremely addicting!

What will be surprising to many bakers is how easily these Key Lime Brownie Bars pull together. They are “easy peasy lemon squeezy” in the truest sense of the popular phrase. In fact, the most time-consuming part is zesting and juicing the limes. However, the payoff for this “hard work” is huge. Everyone will think you spent much more time creating these bad boys. Family and friends will love you more and complete strangers will become instant friends after indulging in these bars. 🙂

Four Important Tips for Baking Success with Key Lime Brownie Bars

This is what I have learned after making this recipe for Lemon Brownie Bars and Key Lime Brownie Bars four (4) times this past week—which included the original recipe and gluten free version.

  1. Be sure to bring butter fully to room temperature. It is imperative to have your butter softened to room temperature as outlined for the second tip.
  2. Mix the ingredients in the order stated in the recipe. The fat in the softened butter coats the flour and sugar then becoming well saturated thus creating a very moist and exceptional crumb. Do not cream the butter and sugar together, then add the eggs and flour mixture. This will create a too “cakey” texture and drier crumb. Remember, we are after dense and fudgy here.
  3. After blending together the dry ingredients, do not “beat” in the butter, eggs, lime juice and zest and then continue beating for 2 minutes or more. This is a serious “no-no” and will just cause the batter to become aerated (incorporating air). This will then cause too many air pockets after baking as well as create an undesirable drier crumb. It is essential to “stir” in, by hand (or using the ‘stir’ setting of a stand mixer), the wet ingredients and not aerate the batter. This is how the fudgiest of brownies are mixed, by hand. Again, fudgy is what we are after.
  4. Do not overbake. Just as with chocolate brownies, overbaking will create a dry brownie. Bake for exactly 25 minutes and no longer. Be sure that your oven is properly calibrated or use an oven thermometer to ensure the proper temperature.

Key Lime Brownie Bars or Key Lime Brownies

Fudgy, bursting with Key Lime flavor and irresistible! The texture of these Key Lime Brownie Bars is very similar to brownies and tasting the glaze gives one the sense of being in the tropics. Perfect for summer entertaining and picnics. Recipe includes an equally irresistible gluten free version.

Ingredients

  • For the Key Lime Brownie Batter
  • 1 cup (125 grams) all-purpose flour, such as Gold Medal®
  • 1 cup (200 grams) organic granulated cane sugar
  • ½ teaspoon (2.4 grams) kosher salt
  • 2/3 cup (150 grams) unsalted butter, softened to room temperature
  • 2 large eggs + 1 large egg white (mine weighed 137 grams w/o shells)
  • 1 tablespoon + ½ teaspoon (7 grams) freshly grated Key Lime zest
  • 2 tablespoons + 2 teaspoons (40 ml) freshly squeezed Key Lime juice
  • For the Key Lime Glaze
  • ¾ cup (94 grams) confectioners’ sugar, sifted
  • 1 tablespoon + 1 teaspoon (20 ml) freshly squeezed Key Lime juice
  • 2½ teaspoons (5 grams) freshly grated Key Lime zest
  • Special Equipment & Supplies
  • Parchment paper for lining baking pan, such as Beyond Gourmet™

Directions

Arrange oven rack in lower third of oven and preheat oven to 350ºF. Lightly grease a 9x9-inch metal baking pan with shortening. (I like to use my Williams-Sonoma Goldtouch® Nonstick Square Cake Pan.) Line pan with baking parchment so there is an overhang. Do this by measuring parchment 4 inches in length additionally at each side of pan. This will allow 2 inches of coverage on each end once folded and tucked in. This will create “handles” which will help removing bars from pan and to transfer to cutting board to cut into even bars after cooling.

Prepare the Key Lime Brownie Batter: Using an electric stand mixer fitted with paddle attachment, or handheld mixer and large bowl, stir together flour, sugar and salt until well combined. Add the butter and mix until well combined, but do not “beat” at high speed which would incorporate too much air.

In a small bowl, whisk the eggs, lime zest and juice together. Scrape and pour into batter using a rubber spatula. Mix together on low mixer setting until well blended and smooth, scraping down sides of bowl as necessary with rubber spatula. Or, stir by hand using a rubber spatula until well blended and smooth. Do not “beat” at high speed with mixer.

With a rubber spatula, scrape batter into prepared pan and smooth the top. Bake in preheated oven until golden brown around the edges and firm to the touch in the center, about 25 minutes. (Do not bake over 25 minutes or the brownie bars will be too dry.) Transfer to wire rack and allow the brownie cake to cool at least 1 hour before removing from pan. Cool completely before spreading on glaze.

Use the baking parchment on sides of pan to lift brownie cake out and transfer to cutting board. Once the brownie cake is completely cool, prepare the glaze.

Prepare the Key Lime Glaze: In a medium bowl, whisk together sugar, lime juice and zest until smooth and creamy. Pour glaze over cooled brownie cake and spread evenly over the top using a metal angled icing spatula or regular icing spatula.

Allow glaze to dry slightly on the surface before cutting into bars and serving. Store in airtight container at room temperature or in the refrigerator.

Recipe Notes

Tips:

For Gluten Free Option: Substitute 1 cup (128 grams) Cup4Cup (C4C) Gluten-Free Flour, available at Williams-Sonoma, for regular all-purpose wheat flour called for in recipe.

Be sure to bring butter fully to room temperature. It is imperative to have your butter softened to room temperature as outlined in the next tip.

Mix the ingredients in the order stated in the recipe. The fat in the softened butter coats the flour and sugar then becoming well saturated thus creating a very moist and exceptional crumb. Do not cream the butter and sugar together, then add the eggs and flour mixture. This will create a “too cakey” texture and drier crumb. Remember, we are after dense and fudgy here.

After blending together the dry ingredients, do not “beat” in the butter, eggs, lime juice and zest and then continue beating for 2 minutes or more. This is a serious “no-no” and will just cause the batter to become aerated (incorporating air). This will then cause too many air pockets after baking as well as create an undesirable drier crumb. It is essential to “stir” in, by hand (or using the ‘stir’ setting of a stand mixer), the wet ingredients and not aerate the batter. This is how the fudgiest of brownies are mixed, by hand. Again, fudgy is what we are after.

Do not overbake. Just as with chocolate brownies, overbaking will create a dry brownie. Bake for exactly 25 minutes and no longer. Be sure that your oven is properly calibrated or use an oven thermometer to ensure the proper temperature.

After measuring confectioners’ sugar for glaze, sift to prevent lumps.

If making the glaze in advance, keep it covered with plastic food wrap to keep it smooth and prevent it from drying out.

You always make me smile!

    Good golly Stacy – these bars are fantastic! I just cannot get over the texture – incredible! I have always “beaten” in the wet ingredients with the dry – thank you for the tip not to. So looking forward to that Key Lime Margarita Cheesecake Cake!!

  5. Oh girl, I love all these citrus treats that you are sharing – I am still dreaming about your lemon bars and these are just as divine! They look incredible and I just want to drink that glaze up! You’ve done it again my friend but I love it 🙂 Pinned!

    Chloe @ foodlikecake recently posted…Malted Milk CookiesMy Profile

  7. Awesome! I was thinking about making the lemon bars you posted, but these actually sound better with lime flavors.
    Baby June recently posted…The vegan Elvis sandwichMy Profile

    • Thank you! You know, before I was able to find Key Limes, I used half lemon and half lime. I would choose only one zest (lemon or lime) for the icing though. It looked weird with both! 😉 If you love Key Lime anything, you will love these bars. Thanks for stopping by and let me know if you make them!

  8. You’re killing me with these citrus brownie bars!!! I REALLY need to make them now! I LOVE key lime and it’s probably my favorite flavor of pie so I think this bar shoots to the top of my ‘must-make’ list…you’re a genius, Stacy!!!
    Julie @ Table for Two recently posted…Garlic Sweet Potato FriesMy Profile

    • Thank you, Julie! I hope you make these bars soon…whether lemon or Key Lime. The texture is amazing and the glaze really is the proverbial ‘cherry on top’. 🙂

    whatjessicabakednext recently posted…Classic Chilli con CarneMy Profile

    • Thank you, Jessica! You will love these bars when made GF. Surprisingly (or maybe not so surprisingly considering the excellent GF flour I used), I even liked them better than the traditional recipe! It’s all about ratio and temperature of ingredients as well as mixing method to achieve the ‘fudgy’ factor. The GF flours loved this recipe. 😉 Let me know if you make these bars, whether lemon or Key Lime. 🙂

  11. Maria | Pink Patisserie says:

    A lime shortage?? Say it isn’t so. I’ve also heard there maybe an orange shortage as well, and beef is in short supply too. Scary times.. I love that you could snag some though to make these and I love Laura’s suggestion of making them for Cinco. Perfection!

    • Exactly, Maria. Scary times. Have mercy. I didn’t know about the orange shortage or that beef is in short supply. Yes, I was lucky to find some Key Limes here in Indy. Amazingly. Thanks for stopping by, my friend!

  12. Stacy, these bars are SO gorgeous! Cakey, light, fresh and full of citrus flavor – everything I’m craving right now! Definitely need to make these happen for my next girls’ night in. Love this summery dessert. Thanks for sharing, girl!

    • Thank you, Georgia! My pleasure. I hope you’ll make these bars soon. You and your gal pals will love them!

  13. Ahhh the lime! the lemon from your previous post that I still can’t stop thinking about! The outrageous chewiness of these bars! It’s all too much!

    And if that weren’t enough, I cannot find a decent lime to save my life. I kid you not. I finally found some and they were rock hard and 2 for $3! $1.50 for a rock with zero juice. Life is so cruel!
    Lindsey @ American Heritage Cooking recently posted…Cream Cheese Chocolate Chip Cookies {And A Birthday Wish}My Profile

    • Mercy me, Linds! So sorry to hear you’ve been slammed with the lime shortage! Ugh. Wish I could send you some from my stash. Sending out prayers that limes will show up soon in your market. Meanwhile, make the lemon bars to cheer you up! 🙂

  14. You had to go and make these bars in my favorite citrus flavor! These look even better than the lemon…it must be those festive little flecks of green key lime zest? I love this, Stacy, and of course, I’m pinning it. I need to try these out very soon! 🙂
    marcie recently posted…Mango Tomatillo GuacamoleMy Profile

    • Thank you, Marcie! I’m glad you enjoy Key Lime desserts like I do. Make these soon and you won’t regret it. Thanks for the pin, too! 🙂

  15. I LOVE key lime pie and I suspect I wuld love these key lime brownies as well. Looks sooooo delicious!
    Bianca @ Confessions of a Chocoholic recently posted…Tres Leches Ice Cream – No Ice Cream Maker Needed!My Profile

  16. I love key lime pie and these look amazing Stacy! Thank you for sharing them!

  17. Having lived in Key Largo, Florida with Key limes growing in my yard, you know I would love one of your bars. 🙂
    Karen (Back Road Journal) recently posted…A New England BathroomMy Profile

    • Thanks, Karen! I love knowing that you once lived in Key Largo and had Key limes always within reach. 🙂 Have a wonderful weekend!

  18. Stacy I can feel the little pucker I’d get from a bite of these beautiful bars – love the brownie texture – great pics!

  20. Oh wow — a key lime bar with the moist chewy texture of brownies? That sounds absolutely incredible, especially with the key lime glaze drizzled on top. This looks perfect for Cinco de Mayo!
    Jamie@Milk ‘n’ Cookies recently posted…Favorite Chocolate Chip CookiesMy Profile

  21. Yummy recipe! Your brownies look so moist and delicious. I feel like I could just grab it straight from my computer screen (ha, if only). Sadly, I will have to satisfy myself by “eating” with my eyes 😉
    Monica recently posted…Stuffed Chocolate Chip CookiesMy Profile

    • Thank you, Monica! Wish I could *poof* you a platter of these treats. 🙂 Citrus brownies are where it is at for spring and summer. Be forewarned…they’re addicting!

  22. Charmaine says:

    Would these work with coconut flour do you think?

    • Hi there, Charmaine! Thank you for writing with such a great baking question. For this recipe, however, I would definitely have to develop it using a paleo flour blend. If you do make this recipe with coconut flour, let me know how it works out. 🙂 Thanks again for writing and good luck!
