Desserts
This Hershey's fudge brownie pie recipe delivers the ultimate chocolate dessert experience—three decadent layers of rich brownie, velvety fudge, and a crispy oat crown that looks impressive yet requires no special skills.
The secret lies in precise baking temperatures and chilling times that prevent cracking while maintaining that signature Hershey's chocolate flavor. I've perfected this recipe over years of holiday baking, ensuring every slice delivers that perfect balance of fudgy, cakey, and crispy textures.
The foundation starts with a buttery pie crust that forms an unbreakable base, followed by a brownie layer baked just until set but still moist.
Between the brownie and the fudge filling comes a strategic chilling period—this is where the magic happens, allowing the fudge to set properly without becoming grainy.
The oat crown, made from crushed oats and brown sugar, bakes until golden and crispy, adding both visual appeal and satisfying crunch to every bite.
What you'll end up with is a showstopping dessert that tastes like a cross between brownie batter and fudge sauce, all held together by that perfect pie structure.
The fudge layer stays smooth and rich, the brownie remains tender yet firm enough to slice cleanly, and the oat crown adds a delightful contrast in every bite. This is the kind of dessert that disappears quickly at gatherings but always gets rave reviews.
Perfect for holiday celebrations, birthday parties, or when you simply want to indulge in chocolate without guilt. The recipe scales easily for crowds, and leftovers keep beautifully in the fridge for up to five days. Let's get baking!
Ingredients for hershey's fudge brownie pie

| Large Eggs 🥚 | 1 whole | Cold, for pie crust |
| Baking Powder 🧂 | ½ tsp | For brownie layer |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🍯 | 1 tsp | Pure vanilla preferred |
| Semisweet Chocolate Chips 🍫 | 1 ½ cups | For brownie layer |
| Whole Milk 🥛 | ½ cup | For brownie batter |
| Powdered Sugar 🍚 | 1 ½ cups | For fudge filling |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for fudge |

The Hershey's Special Dark Chocolate Bars are non-negotiable here—they’re what gives this pie that signature Hershey’s flavor. Grab a family-size bag from Walmart or Target (they’re usually in the baking aisle), or stock up online if you bake often. The unsalted butter needs to be cold for the pie crust—pull it from the fridge right before mixing. For the rolled oats, I always grab the Quaker Old-Fashioned kind—they crush perfectly for that crispy oat crown. If you’re short on time, the pre-crushed oats at Trader Joe’s work too, but they’re pricier. The powdered sugar should be Domino or Dulce de Leche brand—both dissolve smoothly into the fudge filling without clumping.
No Hershey’s bars? Ghirardelli squares are the closest substitute—they’ve got that same rich, melt-in-your-mouth quality. Short on heavy whipping cream? Full-fat coconut cream works surprisingly well for the fudge, though it’ll have a slight coconut flavor. The vanilla extract is where you can splurge—Nielsen-Massey or McCormick Pure are my go-tos, but even the Walmart store brand gets the job done. For the oat crown, if you’re out of brown sugar, white sugar plus a pinch of molasses mimics the flavor. And if you’re making this ahead, pre-mix the dry ingredients for the brownie layer and store in an airtight container for up to 2 weeks—just add the wet ingredients when you’re ready to bake.
This pie is a make-ahead champion—the layers actually taste better after chilling overnight. Store it in the fridge for up to 5 days, covered tightly with plastic wrap and foil. For the oat crown, keep it in an airtight container at room temperature for 3 days or freeze for 2 months. The fudge layer stays velvety if you add a thin layer of parchment paper between it and the brownie before chilling. And if you’re serving a crowd, double the oat crown mix—it’s the first thing to disappear!

Step-by-step instructions for Hershey's fudge brownie pie
This decadent pie delivers layers of fudgy brownie, rich chocolate fudge, and a crispy oat crown—every bite is pure chocolate heaven.
Prepare the Crispy Pie Crust
In a large bowl, combine the 1 cup unsalted butter, 2.5 cups all-purpose flour, 0.5 cup granulated sugar, 0.5 tsp salt, and 1 whole large egg. Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. This texture is crucial for flaky layers.
Press the dough evenly into a 9-inch pie dish, creating a ¼-inch thick crust. Use a fork to prick the bottom all over with small holes to prevent puffing during baking. Chill the crust in the refrigerator for 30 minutes while you prepare the brownie layer. The cold dough prevents shrinking and ensures a sturdy base for your pie.
Bake the Crust and Create the Brownie Layer
Preheat your oven to 375°F. Line the chilled pie crust with parchment paper, fill it with pie weights or dried beans, and bake for 10 minutes. Remove the weights and bake for another 5 minutes until the crust is lightly golden. This pre-baking step prevents a soggy bottom when you add the wet brownie batter.
In a separate bowl, melt the 8 oz Hershey's Special Dark Chocolate Bars with the 1.5 cups semisweet chocolate chips and 0.5 cup unsalted butter over a double boiler or in 30-second bursts in the microwave. Stir until completely smooth, then remove from heat and whisk in the 0.5 cup whole milk, 1 tsp vanilla extract, and 0.5 tsp baking powder. Pour this rich mixture over the pre-baked crust.
Bake the Brownie Layer to Perfection
Return the pie to the oven and bake for 18-20 minutes until the edges are set and the center still has a slight wobble. You want a fudgy texture, not a fully set cake-like brownie. Let the brownie layer cool completely at room temperature before adding the fudge filling—this prevents the filling from melting too quickly.
While the brownie layer cools, prepare the fudge filling by whisking together the 1.5 cups powdered sugar, 1 cup heavy whipping cream, and 1 tsp vanilla extract in a medium bowl until smooth and glossy. Spread this creamy mixture evenly over the cooled brownie layer, creating a smooth surface. Return the pie to the refrigerator to chill for at least 2 hours or until the filling is fully set.
Create the Crispy Oat Crown
In a small bowl, combine the 1 cup old-fashioned rolled oats, 0.5 cup light brown sugar, and 0.5 tsp salt. Drizzle in the 0.5 cup melted butter and mix until the oats are evenly coated. Press this mixture firmly onto the top of the chilled pie, creating an even layer that extends slightly over the edges for a rustic look.
Bake the pie at 350°F for 12-15 minutes until the oat crown is golden brown and crispy. Watch closely—this step happens quickly! The crown should be firm to the touch and have a caramelized aroma. Let the pie cool completely before slicing to allow the filling to set properly and the flavors to meld.
Serve and Enjoy Your Masterpiece
Once fully cooled, use a sharp knife to cut the pie into 8 equal slices. The contrast of the warm, crispy oat crown, the rich fudge layer, and the fudgy brownie base creates an unforgettable texture in every bite. Serve at room temperature for the best experience, and don't forget to pair it with a scoop of vanilla ice cream for the ultimate indulgence.
This pie keeps well in the refrigerator for up to 5 days, making it perfect for holiday gatherings or special occasions. The longer it chills, the more intense the chocolate flavors become—trust the process and enjoy the results!
Pro Tips For Making Hershey'S Fudge Brownie Pie
- Melt Chocolate Slowly: I learned this the hard way—dumping chopped Hershey’s bars straight into hot butter seizes the chocolate and makes it grainy. Instead, melt the butter first, then reduce heat to low and add chocolate in thirds, stirring constantly until fully smooth. Patience here guarantees that rich, velvety texture in your pie filling.
- Whisk Eggs Cold: Room-temperature eggs? Skip it. Cold eggs whip up lighter and hold their structure better in the crust. Crack them into an ice-water bath for 5 minutes before whisking—this prevents curdling when mixed with the hot butter-chocolate combo. Trust me, your crust will be crispier.
- Skip the Overmixing: The moment flour hits the wet ingredients, stop stirring. Overworking the batter develops gluten, turning your pie crust into a dense, cakey mess. Mix just until combined—lumps are fine. The crust’s job is to hold the filling, not steal the spotlight.
- Chill the Crust: After pressing the crust into the pan, freeze it for 15 minutes. This locks it into place so it doesn’t shrink or crack when you pour in the hot filling. No freezer? Pop it in the fridge while you prep the rest—your pie’s edges will thank you.
Flavor customization for hershey's fudge brownie pie
Classic Chocolate Twist
For a deeper chocolate experience, replace the semisweet chocolate chips in the brownie layer with 1.5 cups Ghirardelli 60% Cacao Squares—they add a more intense, slightly bitter note that balances beautifully with the sweet fudge.
I also recommend adding ½ cup toasted pecans to the brownie batter for crunch and nutty depth. Toast the pecans in a dry skillet over medium heat for 5 minutes, then chop them finely before folding into the batter. 🍫
Salted Caramel Fusion
Elevate your pie by adding a salted caramel drizzle between the brownie and fudge layers. Simply heat ½ cup heavy cream with ½ cup granulated sugar in a saucepan until it reaches 235°F, then pour over the cooled brownie layer.
Let it set for 10 minutes before adding the fudge. Top with flaky sea salt (like Maldon) before chilling. The caramel adds a rich, buttery contrast that keeps every bite exciting. 💛
Espresso Infusion
For coffee lovers, stir 1 tablespoon instant espresso powder into the fudge filling mixture before spreading it over the brownie layer. The espresso enhances the chocolate flavor without overpowering it—think of it as a sophisticated boost.
I use Starbucks VIA for consistency, but any high-quality instant espresso works. This variation is perfect for serving with a cappuccino or mocha latte for a full coffee-chocolate experience. ☕
Peanut Butter Swirl
Add a peanut butter swirl to the brownie layer for a nostalgic twist. After pouring the brownie batter into the crust, use a knife to create a well in the center.
Spoon ½ cup creamy peanut butter (like Jif Natural) into the well, then gently swirl it into the batter with a skewer. Bake as directed—the peanut butter will create marbled pockets of flavor that pair perfectly with the fudge.
This is a crowd-pleaser, especially for those who love Reese’s Peanut Butter Cups. 🥜
White Chocolate Crunch
For a lighter but still indulgent variation, fold 1 cup white chocolate chips into the fudge filling before spreading it over the brownie layer. The white chocolate adds a creamy, sweet contrast that brightens the rich chocolate flavors.
I like to use Guittard White Chocolate Chips for their smooth texture. Sprinkle crushed pretzels on top of the oat crown before baking for an unexpected salty crunch that cuts through the sweetness. ✨
Spiced Orange Zest
Brighten the fudge layer with 1 teaspoon orange zest (from about 1 large orange) and ½ teaspoon ground cinnamon. The citrus zest adds a refreshing tang that cuts through the richness, while the cinnamon adds warmth.
This variation works especially well during the holidays or when you want a dessert with a little more complexity. Pair it with a sparkling orange soda for a festive touch. 🍊

Frequently asked questions
Can I make this pie without a pie crust?
The traditional crust adds structural support and prevents the fudge from leaking, but you can create a "crustless" version by baking the brownie layer in a springform pan. Press parchment paper against the sides before baking, then chill the entire pie in the pan. The oat crown will still hold everything together, though the texture will be slightly different. For best results, use a 9-inch round cake pan with removable bottom.
Why does my fudge layer turn grainy?
Graininess happens when the powdered sugar absorbs moisture too quickly. Always use powdered sugar at room temperature and whisk the fudge mixture until completely smooth before spreading. Chill the pie for at least 2 hours in the fridge to let the filling set properly. If it starts grainy, gently reheat the filling (not the whole pie) over low heat with 1 tablespoon heavy cream to restore smoothness.
How do I prevent the oat crown from burning?
Watch the crown closely during the final 12-15 minutes of baking—it burns faster than the rest of the pie. Rotate the pan halfway through baking and reduce heat to 325°F if it starts browning too quickly. For extra insurance, bake the crown on the middle rack where heat is most even. A toothpick inserted into the center should come out clean when done.
Can I prepare this pie ahead of time?
This pie actually tastes better when made a day ahead! Assemble the pie (including the oat crown) and refrigerate uncovered for 4-6 hours to let flavors meld. Wrap tightly with plastic wrap and foil, then store for up to 5 days in the fridge. Bring to room temperature before serving for the perfect texture. The fudge layer will firm up beautifully with time.
What's the best way to serve leftovers?
Slice the pie and store in an airtight container with parchment paper between layers. Reheat individual slices in the microwave for 10-15 seconds to soften the oat crown slightly. For a restaurant-style presentation, drizzle with warmed chocolate sauce and sprinkle with crushed nuts. Pair with a scoop of vanilla ice cream or a dollop of whipped cream to revive the textures.
