Macadamia nut pie is Hawaiʻi's answer to the question of what to do with a counter full of buttery local nuts on a Sunday afternoon. The frame is borrowed from a classic Southern pecan pie — brown sugar, butter, eggs, a pour of corn or maple syrup, and a flaky pie crust to catch the lot. The swap is the headline: Hawaiʻi-grown macadamia nuts replace the pecans, and the result is something richer and slightly more delicate. The mac nut is fattier and sweeter than a pecan, so it carries the custard better and adds a smooth, almost butterscotch note as it toasts in the oven.
Macadamias themselves are an Australian native that took to Hawaiʻi in the late 1800s, with the first commercial plantings on Oahu in the 1920s, then large-scale Big Island expansion in the late 1940s and 1950s as brands like Mauna Loa anchored an export industry tied to the Hamakua and Kona growing belts. A slice of mac nut pie at a Hilo bakery counter or a North Kohala diner is one of those small dishes that earned its place on the Hawaiʻi dessert table the slow way — one bakery at a time.

Easy with a store-bought crust
Ingredients
For the crust
- 1 single-crust 9-inch pie shell, par-baked (homemade or store-bought all-butter)
- 1 egg white, lightly beaten (for sealing)
For the filling
- 1 1/2 cups roasted unsalted Hawaiʻi macadamia nuts, roughly chopped (reserve 1/3 cup whole for the top)
- 3 large eggs
- 1 cup packed dark brown sugar
- 1 cup dark corn syrup OR pure maple syrup (maple makes a deeper, less candy-sweet pie)
- 4 tablespoons unsalted butter, melted and slightly cooled
- 2 teaspoons pure vanilla extract
- 1/2 teaspoon kosher salt
Equipment
- 9-inch metal or glass pie plate
- Mixing bowl + whisk
- Sheet pan (catches drips)
- Foil strips or a pie shield
To serve
- Lightly sweetened whipped cream
- A scoop of vanilla bean ice cream
- Kona coffee, brewed strong
Method
- Par-bake and seal the crust. Heat the oven to 375°F. Roll out the pie crust and fit it into the pie plate. Crimp the edge. Line with parchment and dried beans or pie weights. Bake 12 minutes, lift out the parchment + weights, then bake 4 minutes more until the bottom is dry-looking but not yet golden. Pull from the oven, brush the bottom and sides with the lightly beaten egg white, and let it set 2 minutes — this creates a moisture barrier that keeps the filling from making the crust soggy.
- Toast the macadamia nuts. Spread the chopped mac nuts on a sheet pan and toast 6 to 8 minutes at 375°F, stirring once, until they smell rich and look one shade darker. Watch them — mac nuts have a high oil content and go from golden to burnt fast. Pull them out and let cool 5 minutes.
- Make the filling. Drop the oven to 350°F. In a large bowl, whisk the eggs, brown sugar, corn syrup (or maple syrup), melted butter, vanilla, and salt until smooth and uniform. The mixture should look glossy and pourable, like a thinned caramel sauce.
- Assemble the pie. Scatter the toasted chopped mac nuts over the par-baked crust in an even layer. Slowly pour the filling over the top — the nuts will float upward and form a textured top crust as the pie sets. Arrange the reserved whole mac nuts in a circle in the center for the bakery-counter look.
- Bake and cool. Place the pie on a sheet pan (it will bubble; the pan saves your oven floor). Bake 45 to 50 minutes, until the filling is puffed at the edges and only the center 2 inches still jiggles slightly. If the crust edge browns too fast, shield it with strips of foil around minute 30. Cool on a wire rack at least 2 hours before slicing — warm mac nut pie is liquid in the center and will not hold a slice. It firms up beautifully at room temperature.
Notes from a local cook
Use unsalted, dry-roasted macadamia nuts. The salted, oil-roasted nuts you would eat out of hand will throw off the balance of the filling and leave a slick sheen on top. Most Hawaiʻi-grown mac nuts in the supermarket are oil-roasted and salted by default; check the label and look for dry-roasted unsalted, or buy raw and toast them yourself. The Hamakua Macadamia Nut Company shop and the Mauna Loa Macadamia Nut visitor center both stock dry-roasted unsalted nuts, and Hamakua's shop usually carries raw nuts as well — worth a call ahead if you're making a special trip for them.
Corn syrup versus maple syrup is a real choice. The traditional pecan-pie frame calls for dark corn syrup, which produces a deep, candy-sweet, very firm-set filling. Pure maple syrup (the dark robust kind, not Grade A “golden delicate”) produces a softer set, less aggressive sweetness, and a more nuanced caramel note. Both are correct. I lean maple at home and use corn syrup if I want the bakery-counter version.
Watch the jiggle, not the clock. Mac nut pie continues to set as it cools. Pulling the pie when the center 2 inches still wobble like a barely-set custard is the right call — it will firm up to perfect slice consistency in the 2-hour cool. Bake until the center is totally still and you end up with a stiff, candy-bar-firm filling that loses the soft brown-sugar magic.
For a chocolate version. Sprinkle 1/2 cup semisweet chocolate chips over the chopped mac nuts before pouring in the filling. The chips melt and pool at the bottom into a thin chocolate layer between the crust and the nuts — the move from many Big Island bakery counters that label their version “chocolate macadamia nut pie.”
While You're on the Islands
Eat it made by someone else. Mac nut pie shows up on dessert counters at small Big Island bakeries between Hilo and Kona, which is also where most of the state's mac nut orchards sit. Big Island Candies in Hilo runs a deep mac nut shortbread and chocolate program and is a longtime fixture of any Hilo food walk. See our guide to Big Island dining for more dessert-counter stops.
Buy the ingredients fresh. The Hamakua Macadamia Nut Company visitor center near Kawaihae and the Mauna Loa Macadamia Nut visitor center south of Hilo both sell roasted nuts straight from the source — worth a stop to pick some up for this pie, fresher than anything you'll find bagged at a mainland grocery store.
Bring It Home
What to stock up on before you fly home: a bag of Hawaiian macadamia nuts travels well in a carry-on, and they're the one ingredient that makes this pie taste like the real thing rather than a generic nut pie.
