Lilikoi Bars – Hawaiian Passion Fruit Lemon Bars

Lilikoi. Just saying the word makes me think of Hawaii. That bright, tangy passion fruit with the impossible-to-describe flavor—floral, tart, tropical, and utterly addictive. Now imagine that flavor in a bar dessert, spread over buttery shortbread, sweet and sour in equal measure. That’s lilikoi bars, and they’re the Hawaiian answer to lemon bars.

I first made these for a potluck, worried they’d be too unusual for the crowd. They were gone in ten minutes. People who’d never heard of lilikoi were asking for the recipe. That’s the power of passion fruit—one taste and you’re hooked.

What Is Lilikoi?

Lilikoi is the Hawaiian word for passion fruit, specifically the yellow variety that thrives in Hawaii’s tropical climate. The fruit is small, wrinkly when ripe, and filled with seedy, intensely flavored pulp. The taste is hard to describe—imagine if a lemon and a mango had a baby, then that baby got a degree in tropical aromatics.

Passion fruit is native to South America but found a perfect home in Hawaii. You’ll see lilikoi flavoring everything from cocktails to malasadas to shave ice syrup. In these bars, it replaces lemon for a tropical twist on a classic.

Ingredients

For the Shortbread Crust

• 1 cup (2 sticks) butter, softened
• 1/2 cup powdered sugar
• 2 cups all-purpose flour
• 1/4 teaspoon salt

For the Lilikoi Filling

• 4 large eggs
• 1 1/2 cups granulated sugar
• 1/3 cup lilikoi (passion fruit) concentrate or puree
• 2 tablespoons lemon juice
• 1/4 cup all-purpose flour
• Powdered sugar for dusting

Instructions

Make the Crust

1. Preheat oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving overhang for easy removal.
2. Beat butter and powdered sugar until light and fluffy.
3. Add flour and salt, mix until just combined. Dough will be crumbly.
4. Press evenly into prepared pan. Use the bottom of a measuring cup to pack it down firmly.
5. Bake 18-20 minutes until edges are lightly golden. Remove but keep oven on.

Make the Filling

1. While crust bakes, whisk eggs and granulated sugar until well combined.
2. Add lilikoi concentrate, lemon juice, and flour. Whisk until smooth.
3. Pour filling over hot crust immediately after it comes out of the oven.
4. Return to oven and bake 20-25 minutes until filling is set (it shouldn’t jiggle when you shake the pan).

Cool and Serve

1. Let cool completely in pan—at least 2 hours, or refrigerate for 1 hour.
2. Use parchment overhang to lift bars from pan.
3. Dust generously with powdered sugar.
4. Cut into squares with a sharp knife, wiping between cuts.

Where to Find Lilikoi

• Frozen concentrate: Hawaiian Sun and Goya brands are available at many grocery stores and online
• Fresh passion fruit: Asian markets, specialty grocers, or online. Wrinkly fruit is ripe—scoop out the pulp and strain out seeds
• Passion fruit puree: Frozen section of international markets, or order online (Perfect Puree, Boiron)

Tips for Perfect Lilikoi Bars

• Pour filling on hot crust: This helps the layers bind together and prevents a soggy bottom.
• Don’t overbake: The filling should be set but not brown. Overbaking makes it rubbery.
• Cool completely: Cutting warm bars results in a gooey mess. Patience pays off.
• Sharp knife: Use a thin, sharp knife wiped clean between cuts for clean edges.
• Room temperature butter: For the crust, soft butter incorporates better.

Variations

• Macadamia Crust: Add 1/2 cup finely chopped macadamia nuts to the crust
• Coconut Lilikoi Bars: Add 1/2 cup shredded coconut to the crust
• Lilikoi-Lime Bars: Replace lemon juice with lime juice for extra tropical tang
• White Chocolate Drizzle: Drizzle melted white chocolate over cooled bars

Storage

• Room temperature: Covered, up to 2 days
• Refrigerated: Up to 1 week (texture is actually better chilled)
• Frozen: Up to 2 months—thaw in refrigerator overnight

The Taste of Hawaii

Lilikoi bars are my secret weapon for introducing people to Hawaiian flavors. They’re familiar enough (everyone knows lemon bars) but different enough to spark curiosity. That first bite—the buttery crust giving way to tangy, floral, tropical filling—always gets a reaction.

Make these for your next gathering. Watch people’s faces light up. Answer the inevitable question: “What IS this flavor?” And smile, because you’ve just introduced them to lilikoi.
