• Vanilla extract (1 teaspoon): Enhances overall flavor with warm, fragrant notes.
• Kosher salt (½ teaspoon): Balances sweetness and brightens the flavors.
• All-purpose flour (240 g): Provides structure for the crust’s sturdy, yet delicate texture.
• Unsweetened coconut flakes (60 g): Infuses the crust with a subtle tropical texture and aroma.
• Egg yolks (6): Add richness and help set the luscious key lime filling.
• Roland Foods Cream of Coconut (15 oz): Delivers creamy coconut flavor, adding depth and sweetness.
• Sweetened condensed milk (14 oz): Creates the silky, sweet foundation of the tangy filling.
• Key lime juice (250 g): The star that brings the citrus punch and authentic key lime taste.
• Heavy cream (113 g, cold): Whipped to snowy peaks, it crowns each bar with light decadence.
• Granulated sugar (12 g): Sweetens the whipped cream just right without overpowering.

How to Make Coconut Key Lime Bars Recipe

Step 1: Prepare the Coconut Shortbread Crust

Start by creaming the butter in a stand mixer until luxuriously smooth. Then add powdered sugar, vanilla, and salt—this combination layers sweetness and flavor. Slowly mix in the flour to build that classic shortbread texture, then fold in coconut flakes for bite and aroma. Press this dough evenly into your pan using a piece of parchment paper—it prevents sticking and helps get a smooth surface. Chill in the fridge to firm up the crust, then dock it with a fork to ensure it bakes evenly. Bake until golden brown and let cool completely.

Step 2: Whisk Together the Coconut Key Lime Filling

Crank up the oven slightly and whisk your egg yolks until frothy, preparing them to bind the luscious filling. Stir in the cream of coconut, sweetened condensed milk, and freshly squeezed key lime juice for that unmistakable tang. Pour this silky mixture atop your cooled crust, then bake until the edges bubble and the top just starts to turn golden, signaling it’s perfectly set but still delightfully creamy inside.

Step 3: Chill and Whip the Finishing Touches

Once out of the oven, patience is key—cool the bars at room temperature first, then refrigerate uncovered overnight. This step lets the flavors meld and the texture firm up beautifully. Meanwhile, whip your chilled heavy cream with a touch of sugar until it forms medium peaks, capturing airiness that will be the perfect contrast to each slice’s creamy tartness. Pipe or spoon a generous dollop on every bar just before serving.

Freezing

You can freeze these bars for up to 2 months by wrapping them tightly in plastic wrap and then foil. When ready to indulge again, thaw them overnight in the fridge to preserve that creamy texture without sacrificing flavor.

Reheating

These bars are best enjoyed chilled, but if you prefer them slightly warm, let them sit at room temperature for about 20 minutes. Avoid microwaving as it may affect the filling’s silky consistency.

FAQs

Can I use regular lime juice instead of key lime juice?

Absolutely! While key lime juice has its own unique, slightly more floral flavor, regular lime juice will still provide that refreshing citrus punch, just with a slightly different profile.

Do I have to use cream of coconut or can I substitute?

Cream of coconut adds both sweetness and coconut flavor that are essential here; however, if you can’t find it, try using coconut milk with a bit of added sugar, though this might slightly change the texture and taste.

Is it possible to make these bars gluten-free?

Yes, by swapping all-purpose flour for a gluten-free flour blend designed for baking, you can enjoy these bars gluten-free. Just be sure the blend includes xanthan gum for structure.

Can I make the crust in advance?

Definitely! You can prepare and chill the crust dough a day ahead, then bake when ready to finish the filling and assembly. It’s a great way to save time on the day you want to serve them.

What’s the best way to get clean cuts when slicing these bars?

Use a sharp knife warmed under hot water and wiped dry before slicing. This prevents sticking and helps you achieve neat edges every time.
