Cold, towering, and unapologetically messy, Duke’s Hula Pie copycat is the kind of dessert that gets remembered long after the plates are cleared. The magic is in the contrast: a crunchy Oreo crust, ultra-soft vanilla ice cream folded with toasted macadamias, and a hot fudge finish that slides over the edges instead of sitting politely on top. It looks extravagant on the table, but the steps are straightforward once you know how to build it.
What makes this version work is the order. The crust needs to be packed tight and brought all the way up the sides so it can support the mound of ice cream. The ice cream should be softened just enough to fold through the nuts without turning soupy, and the pie needs a full freeze so the hot fudge can cling instead of melting into a puddle. Toasting the macadamias gives the filling a deeper, richer flavor that tastes closer to the restaurant version.
Below you’ll find the small details that matter most: how to press the crust so it holds its shape, how to keep the ice cream from collapsing, and how to serve the pie with that dramatic hot fudge-and-whipped-cream finish.
The crust held up even under all that ice cream, and the hot fudge stayed thick instead of running everywhere. My family kept going back for “just one more sliver” until the pie was gone.

Why This Pie Holds Its Shape Instead of Slumping
A frozen cream pie can go wrong fast if the crust is too shallow or the filling is too soft. This one stays sturdy because the Oreo crust is packed up the sides of a deep dish pie plate, which gives the ice cream a wall to lean on while it freezes. If the crust is loose, the first slice breaks apart before it even reaches the plate.
The other key is using softened ice cream, not melted ice cream. You want it pliable enough to fold with the macadamias, but still thick and spoonable. Once it goes into the crust, the freezer does the real work. Four hours gives you a sliceable pie; any less and the hot fudge will melt straight through the center.
What Each Ingredient Is Actually Doing in This Pie
- Oreo cookies — These give you a dark, chocolatey crust with enough structure to stand up to the ice cream. Regular chocolate sandwich cookies work best here because the filling helps the crumbs bind when you add the butter.
- Unsalted butter — Butter is what turns cookie crumbs into a crust that slices cleanly. If the mixture still looks sandy after stirring, it needs a little more mixing before you press it in; dry crumbs will crumble out of the pan.
- Vanilla ice cream — Use a good, full-fat ice cream here. Lower-fat versions freeze harder and taste icier, which takes away from the creamy middle that makes this pie feel like the restaurant version.
- Macadamia nuts — Toasting them matters. Raw macadamias are mild and a little soft; toasted nuts bring the buttery crunch this pie needs and keep the filling from tasting flat.
- Hot fudge sauce — A thick fudge sauce clings to the cold surface instead of disappearing into it. If yours is too stiff, warm it just until pourable; if it’s thin, it will run off the pie before you can get it to the table.
- Whipped cream — This is the finish that makes the pie feel tall and dramatic. Use whipped cream that holds soft peaks so it keeps its shape against the hot fudge and doesn’t melt into the ice cream too quickly.
Building the Layers So the Pie Slices Cleanly
Pressing the Crust All the Way Up the Pan
Mix the crushed Oreos and melted butter until every crumb looks moistened, then press the mixture firmly into a 9-inch deep dish pie plate. Work it up the sides as well as across the bottom; that extra height is what supports the overfilled ice cream. A flat-bottomed measuring cup helps compact the crumbs without leaving gaps. If the crust feels fragile, it hasn’t been pressed hard enough.
Folding in the Macadamias Without Melting the Ice Cream
Soften the ice cream just until it gives when stirred, then fold in 1 cup of the toasted chopped macadamias. Stir gently with a spatula, because aggressive mixing turns the ice cream loose and streaky. You want the nuts distributed evenly, but you don’t want to work so long that the filling starts collapsing before it hits the crust.
Freezing Until the Center Is Firm All the Way Through
Mound the filling high in the crust, above the rim if needed, then freeze it for a full 4 hours. The pie should feel solid in the center, not just cold on the outside, before you add the fudge. If you rush this part, the hot fudge softens the top and the whole slice slumps the second it hits the plate.
Adding the Fudge and Cream at the Last Minute
Warm the hot fudge only enough to make it pourable, then drizzle it over the frozen pie just before serving. Add the whipped cream in a tall, generous layer, then scatter the remaining macadamias over the top. The pie should go straight from freezer to table here, because once the fudge hits the cold surface, it starts setting fast.
How to Adapt This Pie for Different Eaters and Different Pans
Dairy-Free Version
Use a dairy-free vanilla ice cream, coconut-based whipped topping, and a dairy-free fudge sauce. The texture will still be creamy, but the flavor shifts a little toward coconut, so choose an ice cream that stays neutral if you want the macadamias and chocolate to stay front and center.
Gluten-Free Crust Swap
Use certified gluten-free chocolate sandwich cookies in place of Oreos. The crust mixes and bakes up the same way, but you still want to press it firmly so it doesn’t crumble when sliced.
Extra-Nutty Version
If you want more crunch, add a few spoonfuls of chopped macadamias between the ice cream and the whipped cream. That gives each slice a little more texture, but keep the pieces chopped fairly fine so the pie still cuts cleanly.
Storage and Reheating
- Refrigerator: Don’t store this pie in the fridge. The ice cream will melt into a puddle and the crust will turn soggy.
- Freezer: Wrap leftovers tightly and freeze for up to 1 week. For the cleanest slices, freeze the pie uncovered for 30 minutes after assembling the whipped cream topping, then cover once the top is firm.
- Reheating: There isn’t a reheating step for this dessert. Let slices sit at room temperature for 5 to 8 minutes before serving so the knife can cut through the crust without cracking the ice cream.

Ingredients
Equipment
Method
- Combine crushed Oreos and melted butter, then stir until the crumbs look evenly coated and sandy. Press firmly into a 9-inch deep dish pie plate, covering the bottom and all the way up and over the sides.
- Fold 1 cup macadamia nuts into softened vanilla ice cream, mixing until the nuts are distributed throughout. Spoon the ice cream into the Oreo crust and mound generously, piling it high over the rim.
- Freeze the pie for 4 hours until completely firm, with a flat surface so the filling sets evenly. Visual cue: the top should feel solid when pressed gently with a fingertip through the crust edge.
- Just before serving, drizzle the hot fudge sauce over the entire top in thick ribbons so it soaks the surface. Visual cue: dark fudge should pool slightly where the ice cream is highest.
- Pile whipped cream dramatically high on top so it forms a mound that covers the fudge. Visual cue: the whipped cream should hold peaks and not melt into the fudge.
- Scatter the remaining macadamia nuts over everything for a crunchy, toasted finish. Visual cue: nuts should be visible across the whole top, including the center pile and edges.
- Serve immediately with extra hot fudge on the side so each slice can be finished to taste. Visual cue: hot fudge should be ready for drizzling as the pie is plated.
