Ingredients for hula pie copycat
Pantry staples transformed into Hawaii's iconic dessert—creamy swirls and caramelized oat crown await.
| Ingredient | Amount | Notes |
|---|---|---|
| Instant Vanilla Pudding Mix 🍮 | 2 boxes | Vanilla flavor, 3.4 oz each |
| Large Eggs 🥚 | 4 whole | Room temperature for best mixing |
| Whole Milk 🥛 | 2 cups | Full-fat for creaminess |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for topping |
| Rolled Oats 🌾 | 2 cups | Old-fashioned, not quick oats |
| Packed Brown Sugar 🍚 | 1 cup | Lightly packed for accurate measure |
| Granulated Sugar 🍬 | ½ cup | For filling sweetness |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Pure Vanilla Extract 🍋 | 1 tbsp | High-quality for authentic flavor |

| Vanilla Ice Cream 🍦 | 2 cups | For serving, premium quality |
| Heavy Whipping Cream 🥛 | ½ cup | Optional garnish |
The pudding mix is your foundation, but Jell-O brand delivers the most reliable texture for this recipe. Grab the 3.4-ounce boxes—they're specifically formulated for pie fillings. Rolled oats are non-negotiable here; Quaker Old-Fashioned is my go-to for that perfect caramelization. The butter must be cold when mixed with the oats to create that signature crispy crown. For the milk, whole milk ensures the filling stays rich and creamy rather than watery. If you're using a different brand of pudding mix, test a small batch first as some varieties can make the filling too thin or too thick.
No instant pudding mix? Homemade vanilla custard works beautifully—just whisk 2 cups heavy cream, 1 cup whole milk, 1 cup sugar, 6 egg yolks, and 1 tbsp vanilla until thickened. For the oat topping, granola or crushed graham crackers can substitute in a pinch, though the texture won't be identical. The vanilla extract is where you shouldn't cut corners—Nielsen-Massey or McCormick Pure brands provide the authentic depth of flavor. If you're serving this to a crowd, consider doubling the oat topping recipe to ensure everyone gets a proper crunchy slice. The filling can be made a day ahead and chilled, which actually improves the texture when baked later.
Store any leftover filling in an airtight container in the fridge for up to 3 days, though it's best used immediately. The oat topping mixture can be prepped ahead and refrigerated for 24 hours, but it's best baked fresh for optimal crispiness. Once baked, the pie keeps well at room temperature for 2 days if properly covered. For longer storage, slice the pie and freeze individual portions for up to 3 months. Reheat slices in the oven at 350°F for 5-10 minutes to restore that molten center. The contrast between the warm, gooey filling and crispy top is what makes this pie unforgettable—so serve it warm with that vanilla ice cream for the full experience.

Step-by-step instructions for hula pie copycat recipe
Master this iconic dessert with precise technique and restaurant-quality results.
Prepare the Crunchy Oat Crown
Preheat your oven to 350°F and line an 8-inch round baking dish with parchment paper, leaving an overhang for easy removal. In a food processor, pulse the 2 cups rolled oats until they resemble coarse sand. Transfer to a mixing bowl and whisk in the 1 cup packed brown sugar, 0.5 cup granulated sugar, and 0.5 tsp Diamond Crystal kosher salt until evenly distributed.
Melt the 0.75 cup unsalted butter in a saucepan over medium heat, then pour it over the oat mixture while stirring vigorously. The mixture should become moist but still hold its shape when pressed. Press this firmly into the prepared baking dish, creating an even layer about ¼-inch thick. Bake for 12-15 minutes until the edges are golden brown and the top looks toasted. Let cool completely before proceeding—this prevents the filling from causing the crown to soften prematurely.
Whisk the Vanilla Filling to Perfection
In a large mixing bowl, whisk together the 2 boxes instant vanilla pudding mix and the 0.5 cup all-purpose flour to eliminate any lumps. In a separate bowl, lightly beat the 4 whole large eggs until just combined. Gradually whisk the dry ingredients into the eggs, creating a smooth batter.
In a saucepan, heat the 2 cups whole milk over medium heat until it just begins to steam but doesn't boil. Slowly pour the hot milk into the egg mixture while whisking constantly to prevent curdling. Add the 1 tbsp pure vanilla extract and continue whisking until the mixture is completely smooth and homogeneous. The filling should be thick enough to coat the back of a spoon but still pourable. Let it cool to room temperature before using—this ensures proper texture when baked.
Assemble and Bake the Molten Center
Pour the cooled vanilla filling over the chilled oat crown in the baking dish, spreading it evenly to the edges. The filling should reach about ¾-inch from the top of the dish. Place the assembled pie on a baking sheet to catch any potential spills and bake at 350°F for 25-30 minutes. You'll know it's ready when the filling is just set at the edges but still slightly wobbly in the center—this creates the signature molten swirl when served.
Remove from the oven and let cool for 10 minutes before transferring to the refrigerator to chill completely for at least 2 hours. This resting period allows the flavors to meld and the textures to set properly. The pie should hold its shape when inverted, with a firm oat crown and a creamy, slightly tremulous center.
Serve with Vanilla Ice Cream and Garnish
To serve, run a thin knife around the edge of the pie to loosen it from the parchment. Invert onto a serving plate, then carefully remove the parchment. Scoop 2 cups vanilla ice cream into individual bowls and place a slice of pie on top. Drizzle with any accumulated juices from the pie and top with a dollop of 0.5 cup heavy whipping cream for an elegant finish.
This pie delivers the perfect balance of textures—crispy oat crown, creamy custard filling, and cool ice cream. The contrast of temperatures and textures is what makes this dessert legendary. Serve immediately for the ultimate experience, as the ice cream softens slightly against the warm pie.
Pro Tips For Making Hula Pie Copycat
- Whisk Eggs Cold: I learned this the hard way—adding cold eggs to the pudding mix first prevents curdling. Let the milk heat slightly (just until butter melts) but never boil it, then whisk in eggs last. This keeps the texture smooth, not grainy.
- Toast Oats First: Skip the raw oats—lightly toast them in a dry pan for 2-3 minutes until golden. This adds crunch without sogginess and deepens the flavor. (Yes, even if you’re impatient like me, don’t rush this.)
- Don’t Overmix Layers: Stir the pudding base just until combined—overmixing makes it dense. For the oat topping, fold in melted butter in stages to keep it light. The pie’s magic is in the layers staying distinct.
- Chill Before Serving: Resist the urge to dig in right away—let it set for at least 2 hours (overnight is ideal). This lets the flavors meld and the texture firm up. (Your future self will thank you.)
Pro cooking tips for great hula pie copycat
Oat Crown Perfection
The secret to that signature crunchy oat crown lies in proper oat pulverization and butter temperature. Pulse your 2 cups rolled oats in a food processor until they resemble coarse sand—this ensures even caramelization.
Use cold, cubed butter when mixing with the oats to create a firm, crisp texture that won't dissolve prematurely. I find Plugrá brand butter works best for this recipe due to its higher fat content.
Press the mixture firmly into your 8-inch baking dish and bake until golden brown—this takes exactly 12-15 minutes at 350°F. 🌟
Filling Consistency
Your vanilla filling must achieve that perfect "coat-the-back-of-a-spoon" consistency without being too thick. I recommend using Jell-O brand instant pudding mix as it creates the ideal custard texture. When whisking the hot milk into the egg mixture, do it slowly to prevent curdling—this is where most home bakers go wrong.
The filling should be smooth, glossy, and just thick enough to hold its shape when poured. Let it cool completely before assembling to ensure proper texture when baked. ⚡
Baking Time Mastery
Bake your assembled pie at 350°F for 25-30 minutes until the edges are set but the center remains slightly wobbly—this creates that signature molten effect. Use an instant-read thermometer to check the internal temperature: it should reach 190-195°F at the center.
Overbaking will dry out the filling, while underbaking may leave it too runny. The 10-minute rest after baking is crucial—it allows the filling to set slightly before chilling.
Chilling Technique
Never skip the 2-hour chilling period in the refrigerator—this is what transforms your pie from good to legendary. The cold helps the oat crown maintain its crispness while allowing the filling to develop its perfect creamy texture.
I like to chill mine on a wire rack to prevent condensation from forming on the bottom. For even better results, chill overnight—this enhances the flavor development and makes slicing easier. 💪
Serving Temperature
Serve your Hula Pie at room temperature for the best experience—the contrast between the warm filling and cool ice cream is what makes it unforgettable. I recommend cutting slices just before serving to maintain that perfect molten center.
The oat crown should still be crisp when served, so avoid cutting too far in advance. Pair with Breyers vanilla ice cream for that authentic Hawaii Regional Favorite experience. The ice cream softens slightly against the warm pie, creating a magical texture contrast.

Frequently asked questions
Why does the oat topping need to be pulsed in a food processor?
Pulsing the oats creates uniform, coarse particles that caramelize evenly for that signature crispy texture. Whole oats would burn on the outside while staying raw inside. The food processor also helps distribute the sugars and butter more thoroughly, ensuring every bite has that perfect crunch.
Can I make this pie ahead of time?
The filling can be prepared 1 day ahead and stored in an airtight container. The oat topping can be mixed and refrigerated for 24 hours before baking. However, the pie should be baked fresh and served within 2 days for optimal texture. For longer storage, slice and freeze individual portions for up to 3 months.
What if my filling curdles when mixing?
Curdling happens when the hot milk is added too quickly. Whisk the eggs and dry ingredients first, then slowly pour in the warm (not boiling) milk while whisking constantly. If it does curdle, strain the mixture through a fine-mesh sieve to remove lumps. The filling should be smooth and glossy before baking.
Can I use quick oats instead of rolled oats?
No, quick oats won't work—they contain steel-cut pieces that won't caramelize properly. Rolled oats break down more evenly, creating that perfect crispy-yet-tender texture. If you're out of rolled oats, you can pulse old-fashioned oats in a food processor until they resemble coarse sand.
How do I get the oat crown to stay crispy after baking?
Use cold butter when mixing with the oats and press the mixture firmly into the pan. Bake until golden brown, then let it cool completely before adding the filling. Chill the assembled pie for at least 2 hours before serving to maintain crispness. Avoid cutting too far in advance—serve warm for that perfect contrast.
