Four Citrus Coconut Shortbread Bars
A creative twist on classic lemon bars, these citrus bars are made with a coconut shortbread base and curd prepared with four different types of citrus.
Ok, I fully intended on sharing these bars with you next week for Mother’s Day, but I have another citrus-themed dessert planned for next week as well (oh and a fun giveaway, so stay tuned!), so today it is. It was either that or tell you about a salad, which is a pretty exciting salad, but a salad nonetheless.
It’s Friday! We deserve dessert.
If you’re wondering what the heck four citrus coconut shortbread bars are (and why they look so similar to a classic lemon bar), let me tell you. They are, in fact, very similar, but have a few key differences!
Firstly, these bars are made with (if the title was not obvious enough) four different citrus juices! Lemon, grapefruit, orange, and lime juice. The dominant flavors are lemon and grapefruit, but they each contribute varying levels of sweetness and pizzazz (did I just say that?).
Secondly, the curd layer is placed on top of classic shortbread layer that contains unsweetened shredded coconut! Oh, and the curd also has coconut oil in it as well, but I’ll explain that a little bit later. The coconut flavor is subtle, but one of my favorite things about these bars.
Classic lemon bars were probably one of the first desserts I ever made as a kid. I was (and continue to be) a citrus freak growing up. I used to take a wedges of lemon, and literally eat them. Sparkling water with about three or four lemon or lime wedges was my favorite beverage of choice, and when we went on road trips to Hilton Head Island every summer, my mom would routinely pack a few lemons in the car in case we needed them.
I was definitely…special.
It didn’t take me long to realize that most lemon bars did not contain nearly enough lemon juice, and were way, way too sweet. I routinely changed the recipe to contain about 1/4 cup more lemon juice than the recipe called for.
Ironically, lemon bars were also one of the first desserts that Connor and I made together so many years ago! It was a very, let’s call it, memorable experience.
We had just finished pressing down the shortbread layer, and Connor was tasked with whisking together the citrus ingredients. Somehow, he ended up confusing several different ingredients, and added about 5 or 6 tablespoons (!) of baking soda (first offense: it was supposed to be baking powder, second offense: I’m pretty sure the recipe called for maybe a half teaspoon), which resulted in a 3rd-grade-science-volcano-project-like explosion all over our kitchen counter.
Thankfully, the mistake was fairly obvious and we put together another batch, which–as a result of my distraction from the previous incident–I poured directly on top of the uncooked shortbread layer, which I had completely neglected to put into the oven.
At that point, I think I decided to just give up and call it a day (and Connor and I have not baked together since).
Thankfully, these four citrus coconut shortbread bars were, unlike that incident, a successful baking experiment! They were heavily adapted from this New York Times recipe, which caught my eye a few months ago.
Unlike other lemon bars I’ve made in the past, this recipe uses a curd as the top layer, which requires pre-cooking it on the stovetop before layering it over the cooked shortbread layer. It results in a slightly more even curd layer, and does not yield that slightly crispy (yet more often than not, uneven and slightly unattractive) top layer.
In other words, it produces bars that are pretty enough to serve without the need to dust them with a fine layer of powdered sugar! I chose to do this anyway, but feel free to leave this out and sprinkle the tops with toasted or untoasted shredded coconut!
Four Citrus Coconut Shortbread Bars
For the Crust:
- 1¼ cups (150 g) unbleached all-purpose flour
- ¼ cup (50 g) granulated sugar
- ½ cup (60 g) unsweetened shredded coconut
- 3 tablespoons (25 g) powdered sugar
- zest of 1 lime
- ¼ teaspoon Diamond Crystal kosher salt
- 10 tablespoons (5 oz; 140 g) cold unsalted butter cut into cubes
For the Filling:
- ⅓ cup (80 mL) fresh grapefruit juice
- ¼ cup (60 mL) fresh lemon juice
- ¼ cup (60 mL) fresh orange juice
- 1 tablespoon fresh lime juice
- 1¼ cups +. 2 tablespoons (275 g) granulated sugar
- 2 large eggs, plus 3 large egg yolks
- 2 teaspoons (7 g) cornstarch
- 4 tablespoons (2 oz; 60 g) unsalted butter cut into small cubes
- ¼ cup pure virgin coconut oil
- powdered sugar for dusting
- Preheat the oven to 325°F (160°C) with a rack in the center position. Line an 8-inch x 8-inch (20-cm x 20 cm) baking pan with aluminum foil or parchment paper, allowing it to slightly overhang the sides, and grease with baking spray or butter. Set aside.
- Prepare and Bake the Shortbread Layer: In a large food processor, combine the all-purpose flour, sugar, shredded coconut, powdered sugar, lime zest, and salt. Pulse until the shredded coconut is evenly distributed into the flour mixture. Add the cold cubed butter and pulse until the dough just begins to come together. Press the dough evenly (with your hands) into the bottom of the greased baking pan.
- Bake for 30 to 40 minutes, or until the shortbread is golden brown. Set on a wire rack to cool as you finish preparing the curd filling.
- Prepare the Citrus Curd Filling: In a medium saucepan, combine the grapefruit, lemon, orange, and lime juice. Add the granulated sugar, whole eggs, egg yolks, and cornstarch, and whisk together. Place over medium-high heat, stirring continuously, until mixture begins to thicken, roughly 3 to 5 minutes. Boil for roughly 1 minute. Make sure mixture comes to a boil so that the cornstarch activates and cooks through.
- Strain the mixture through a fine-meshed sieve into a medium bowl. Whisk the butter and coconut oil into the curd completely melted and it is very smooth in texture.
- Transfer the curd filling onto the cooked shortbread layer, spreading it into an even layer with an offset spatula. Bake at 325°F (160°C) for 30 to 40 minutes, or until the curd is starting to bubble just around the edges and it is mostly set (it will still jiggle a bit).
- Transfer the pan to a wire rack to cool completely, then transfer to the fridge to chill and set. Use the parchment or foil to lift up the bars. Just before serving, dust the top with powdered sugar. Use a warm (dry) knife to cut into small squares or cubes.
- Storage: Leftover citrus bars can be stored in an airtight container in the fridge and will keep for 5 to 7 days.
Tips for Success:
- Citrus bars should be stored in an airtight container in the fridge, and will keep for 5 to 7 days.

I can’t stop staring at these bars. First – that photo of all the citrus halves? It’s amazing! Citrus + coconut? Dude – this is genius. I love that story of your first time baking together.
I am a big fan of lemon bars, and these take it to another level. I’m looking forward to trying this recipe.
I can’t stop staring at these bars. First – that photo of all the citrus halves? It’s amazing! Citrus + coconut? Duuude – this is genius. I love that story of your first time baking together – you guys had some major “chemistry” (I’m bad at jokes).
I’m thinking of making these tomorrow for a small dinner party. I don’t have coconut oil…I looked at the NYT recipe also and was wondering if I cup sub a fruity olive oil in its place. Thoughts or recommendations?
Hi Jennifer! I think that would work too! But I may omit the coconut from the crust, simply because that’s a lot going on at once. It would probably be fine, but just to be safe? Hope this helps! Let me know what you think!
I’m not sure that I loved citrus enough as a child to eat it as it’s own food group..but it has always been near and dear to my heart. Especially in sweet-tart dessert form. I’m LOVING these bars!
I believe you’ve created my dream lemon bar…the beyond-lemon bar!
I love citrus desserts…. and you put four into one dessert…you ROCK! I’m so making these.
These are so pretty! I’ve NEVER tried a dessert with all four citrus fruits but I’ll have to now that I’ve seen these gorgeous things. I love dessert bars!
These photos are absolutely stunning, Laura! I think citrus photographs so beautifully, and you really captured it here. Love the recipe, too!

I am not normally a citrus dessert person, BUT these look so colorfully! They just make me happy looking at them!
These citrus and coconut shortbread bars look SO delicious and you have captured them perfectly. I love any type of citrus-y sweet dessert so these would be perfect for me.
These look ridiculously good. I have some sweetened shredded coconut I need to use up…do you think I could use it and just cut down on the sugar in the crust?
Hey Abby! Thanks so much. I think you could definitely substitute with sweetened coconut–and maybe decrease the sugar in the crust by 1 or 2 tablespoons? Let me know how it works out, and I can add a note to the recipe for others 🙂
When it comes to citrusy dessert bars, the more pizzazz, the better, I always say. Love these!
Really like citrus and coconut and the colours and the photos. Everything is amazing!
These bars are stunning, Laura! I absolutely love all four citruses bursting within each of these delicate shortbread bars.
These look incredible. Definite a great summer dessert. 🙂
I just love it when a baking experiment comes out better than expected! Citrus Coconut bars look delicious! 🙂
Oh my!! I just love the colour of these. So gorgeous!
Yum…four types of citrus?! These look like sunshine in a bar! The coconut sounds like a lovely addition as well – I can’t wait to try these!
Gorgeous photos, Laura! I love lemon bars and can only imagine how much better these ones are with FOUR kinds of citrus.
Such a funny story about you and Connor baking together. I remember making a cake once when I was about 12 and accidentally quadrupling one of the ingredients. My mom suggested just adding more of everything else to even things out, so we did. We had enough batter to fill every baking vessel in the house and were eating cake for dayyyys.
Oh my gosh! That is so funny! Cake for days sounds kinda fun, now that you think about it–maybe I should ‘accidentally’ do that one day! 🙂 I think that thought has crossed my mind when I’ve accidentally halved recipes (but inevitably not halved certain ingredients), but usually it’s too late to fix at that point.
