How to Make Coconut Key Lime Pie Bars (Video)

Nothing says summer dessert like key lime pie, and these Easy Coconut Key Lime Pie Bars are a fresh, healthier take that’s perfect for picnics, barbecues, or a relaxed Sunday morning. The crust combines superfine almond flour and unsweetened shredded coconut, lightly sweetened with honey. The filling is tangy, creamy, and bright with key lime juice (regular lime juice works fine if key limes aren’t available). These bars are gluten-free by default and easy to adapt to other dietary preferences.

Hi — Linley here. Summer mornings have a special calm to them, especially on Sundays when I love to sit outside with a cup of coffee and recharge. These key lime bars feel like that kind of slow, easy morning — bright, refreshing, and satisfying without being heavy. We developed this recipe as a reminder that summer is coming, even when the weather still feels wintry. The citrusy filling paired with the toasted coconut notes in the crust was enough to make us optimistic right away.

We also put our bars through a very important taste test: Marian, the building manager and our go-to honest critic. She adored them — in fact, she ate two bars while we were chatting, and that enthusiastic response sealed the deal. If you want a dessert that gets real thumbs-up from people who appreciate a great, balanced flavor, these bars fit the bill.

Important Key Lime Pie Bar Ingredients

• Key limes (or regular limes)
• Almond flour (superfine works best)
• Honey (natural sweetener)
• Unsweetened shredded coconut
• Eggs
• Coconut flour
• Coconut oil (melted)
• Vanilla extract and a pinch of salt

These bars are designed to be a healthier version of a classic key lime dessert. The crust uses almond flour and shredded coconut for a naturally gluten-free base, with honey replacing refined sugar. If you prefer, whole wheat or white whole wheat flour can be used as a substitute for the almond flour, though the texture and flavor will change slightly. Coconut oil helps bind the crust and adds a subtle coconut aroma, pairing nicely with the lime filling.

Easy Coconut Key Lime Pie Bars

Ingredients

For the Crust

• 1 1/2 cups almond flour (superfine)
• 1/4 cup unsweetened shredded coconut
• 2 1/2 tablespoons coconut oil, melted
• 3 tablespoons honey
• 1 teaspoon vanilla extract
• 1/8 teaspoon salt

For the Filling

• 4 large eggs
• 1/2 cup key lime juice (regular lime juice works, too)
• 1/2 cup honey
• 4 teaspoons coconut flour
• Optional toppings: Greek yogurt, lime zest, toasted coconut

Instructions

1. Preheat the oven to 350°F (175°C). Line an 8-inch by 8-inch baking pan with parchment paper and set aside.
2. Make the crust: combine the almond flour, shredded coconut, melted coconut oil, honey, vanilla extract, and salt. Mix until the mixture forms a cohesive dough. Transfer into the prepared pan and press evenly to cover the bottom and reach the edges. Use a spatula or your hands to make the crust uniform in thickness.
3. Bake the crust for about 8 minutes at 350°F. Remove from the oven and set aside while you prepare the filling.
4. Prepare the filling: in a medium bowl, whisk the eggs until combined. Add the key lime juice, honey, and coconut flour, whisking until the coconut flour is fully incorporated and there are no lumps.
5. Pour the filling over the partially baked crust and return the pan to the oven. Bake an additional 18–22 minutes, watching closely. Oven temperatures vary; the center should be set but may still be slightly jiggly. If the center cracks slightly, it’s okay.
6. Allow the bars to cool on the stovetop for about 10 minutes, then transfer to the refrigerator. Chill for at least 2 hours to fully set before slicing into 16 squares.
7. Serve chilled with a dollop of Greek yogurt, fresh lime zest, and toasted coconut if desired. These toppings add creaminess and texture while keeping the dessert light.

Tips & Notes

• Bake times depend on your oven—keep an eye on the filling near the end. Slight cracking in the center is normal and does not affect taste.
• If you can’t find key limes, regular limes provide the same bright acidity; the flavor profile will be slightly different but still excellent.
• To toast coconut: spread shredded coconut on a baking sheet and toast in a 325°F oven for 5–8 minutes, stirring once, until golden and fragrant.
• Storage: keep bars refrigerated in an airtight container for up to 4 days. Freeze individual squares for longer storage; thaw in the refrigerator before serving.
• Substitutions: swap honey for maple syrup if desired (flavor will change), or use a dairy-free yogurt topping to keep the recipe fully dairy-free.
