Macadamia nuts were first commercially planted on Oahu in the 1920s, but it wasn’t until the late 1940s and 1950s that large-scale orchards took hold on the Big Island — anchored by brands like Mauna Loa tied to the Hamakua and Kona growing belts. By then, local bakers had already figured out what to do with the rich, buttery nuts: fold them into a brown-sugar custard, pour it into a flaky crust, and call it macadamia nut pie — Hawaiʻi’s answer to the Southern pecan pie.
This guide covers the story behind the pie, the recipe that delivers the real thing (with the exact doneness trick that separates a good slice from a great one), and where to find it — and its key ingredients — on the islands. Whether you’re baking at home or planning a Big Island food crawl, this is the one dessert you don’t want to skip.
Macadamia nut pie swaps in locally grown macadamias for pecans, giving you a richer, butterscotch-like flavor with a softer, more custard-like set. The two non-negotiable rules: use dry-roasted unsalted nuts and pull the pie when the center two inches still jiggle — it firms up perfectly as it cools. Skip the store-bought version if you can; homemade is surprisingly easy and tastes like the islands.

History & Ingredients: Why Macadamias Work So Well Here
Macadamia nuts are natives of Australia, but they found a second home in Hawaiʻi’s volcanic soil and consistent rainfall. The first commercial trees went in on Oahu in the 1920s, and by the 1950s the Big Island’s Hamakua and Kona slopes had become the state’s primary growing region, supplying the nuts that would eventually star in pie fillings across the islands. What makes them different from pecans? Macadamias are fattier and sweeter, with a higher oil content that lets them carry a custard better and adds a smooth butterscotch note when toasted.
The pie itself is a straightforward brown-sugar custard — eggs, dark brown sugar, corn syrup or maple syrup, butter, vanilla, and salt — poured over a layer of toasted, roughly chopped macadamias in a par-baked crust. The nuts float upward during baking, creating a textured top crust. It’s simple, but the quality of the nuts makes or breaks it.
Most supermarket mac nuts in Hawaiʻi are oil-roasted and salted by default — not what you want for baking. Look for dry-roasted unsalted, or buy raw nuts and toast them yourself. Hamakua Macadamia Nut Company and Mauna Loa’s visitor center both sell dry-roasted unsalted nuts; Hamakua also carries raw nuts if you want to control the toasting.
How to Bake Macadamia Nut Pie
The active work is about 25 minutes; the oven does the rest. The sequence below follows the method from Hawaii-Guide.com, which is the most tested version I’ve found.

Preheat oven to 375°F. Fit a single 9-inch pie shell (homemade or store-bought all-butter) into a metal or glass pie plate, crimp the edge, line with parchment and pie weights, and bake 12 minutes. Remove weights and bake 4 minutes more — the bottom should look dry but not golden. Brush the bottom and sides with lightly beaten egg white and let set 2 minutes. This creates a moisture barrier that keeps the crust from getting soggy.
Spread 1½ cups roughly chopped roasted unsalted macadamia nuts on a sheet pan. Toast at 375°F for 6–8 minutes, stirring once, until fragrant and one shade darker. Watch closely — the high oil content makes them go from golden to burnt fast. Let cool 5 minutes. If you’re buying nuts for this, dry-roasted unsalted Hawaiian macadamias are the right choice.
Drop the oven to 350°F. In a bowl, whisk 3 large eggs, 1 cup packed dark brown sugar, 1 cup dark corn syrup (or pure maple syrup — see Variations below), 4 tablespoons melted unsalted butter (slightly cooled), 2 teaspoons vanilla extract, and ½ teaspoon kosher salt until smooth and glossy, like thinned caramel sauce.
Scatter the toasted chopped nuts in an even layer over the par-baked crust. Slowly pour the filling over the top — the nuts will float and form a textured top crust. Arrange a few whole nuts in the center for a bakery-counter look. Place the pie on a sheet pan to catch any bubbles, then bake 45–50 minutes, until the filling is puffed at the edges and the center 2 inches jiggles slightly when you shake the pan. Shield the crust edge with foil strips around minute 30 if it’s browning too fast.
Cool the pie on a wire rack for at least 2 hours. Warm pie is liquid in the center; it firms up beautifully at room temperature. Slice with a sharp knife (heat it under warm water and wipe dry for clean cuts). Serve with lightly sweetened whipped cream, vanilla bean ice cream, or a strong Kona coffee.
Variations to Try
The classic version above is the standard, but two tweaks are common enough on Big Island bakery counters that they’re worth knowing.
Chocolate macadamia nut pie. Sprinkle ½ cup semisweet chocolate chips over the chopped nuts before pouring in the filling. The chips melt and pool at the bottom, creating a thin chocolate layer between the crust and the nuts. This is the version you’ll often see labeled “chocolate macadamia nut pie” at bakeries from Hilo to Kona.
Syrup swap. Dark corn syrup gives a deep, candy-sweet, firm-set filling. Pure maple syrup — specifically the dark robust grade, not the delicate golden — produces a softer set, less aggressive sweetness, and a more nuanced caramel note. Both are correct; the choice changes the pie’s personality. If you lean maple, the pie will be slightly less sweet and a little more sophisticated. If you want the classic bakery-counter taste, stick with corn syrup.
Where to Find It on the Islands
Macadamia nut pie appears on dessert counters at small bakeries between Hilo and Kona, where most of the state’s mac nut orchards sit. Big Island Candies in Hilo is a longtime fixture — they run a deep mac nut shortbread and chocolate program, and their pie slices are worth the stop. For the nuts themselves, Hamakua Macadamia Nut Company near Kawaihae and Mauna Loa’s visitor center south of Hilo both sell roasted nuts straight from the source. If you’re planning a special trip to pick up dry-roasted unsalted nuts or raw nuts, call ahead — stock can vary.
A bag of Hawaiian macadamias travels well in a carry-on and is the one ingredient that makes this pie taste like the real thing rather than generic nut pie. Pick up a bag before you fly home, and you’ll have everything you need to recreate a slice of the islands in your own kitchen.
Storing and Making Ahead
A fully baked and cooled pie keeps at room temperature (68–72°F) for up to 2 days when wrapped tightly or stored in an airtight container. Refrigerate for up to 5 days; let it sit at room temperature for 15–20 minutes before serving to bring back the texture. The pie also freezes well — cool completely, wrap in two layers of plastic wrap and then foil, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat slices in a 350°F oven for 10–15 minutes if you want it warm.
If you’re planning ahead, you can prepare the pie crust up to 2 days in advance (keep it refrigerated) and toast the nuts up to a week ahead (store in an airtight container at room temperature). Assemble and bake on the day you plan to serve for maximum freshness — or bake a day early and reheat gently.
Closing
Macadamia nut pie is more than a dessert — it’s a direct line to the agricultural story of the Big Island, where volcanic slopes and steady rain produce some of the richest nuts in the world. Whether you bake it yourself using the jiggle test or track down a slice at a Hilo bakery counter, it’s a taste worth seeking out.
