Ingredients for hershey bar pie
Twelve ingredients transform into a showstopping pie with molten chocolate magic and crunchy oat crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for flakiness |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for smooth crust |
| Granulated Sugar 🍚 | ½ cup | For crust sweetness |
| Hershey Milk Chocolate Bars 🍫 | 12 oz | Chopped into 1/2-inch pieces |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tsp | Pure alcohol-free preferred |
| Old-Fashioned Oats 🌾 | 1 ½ cups | Blended into fine crumbs |
| Packed Brown Sugar 🍚 | ½ cup | For oat topping |
| Melted Butter 🧈 | ½ cup | For oat mixture |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Ground Cinnamon 🌿 | ½ tsp | Optional for warmth |

Hershey bars are the star here—use the classic milk chocolate for that perfect balance of sweetness and richness. Costco or Trader Joe's often have bulk packs that save money. For the crust, I always make mine from scratch (butter, flour, sugar) because store-bought never gets that flaky perfection. If you're short on time, Pillsbury's refrigerated crust works in a pinch—just brush it with melted butter before filling. The oats? Old-fashioned, not quick—they toast better and give that perfect crunch. Grab a bag from the baking aisle, and if it's been sitting forever, toast them in a dry pan for 5 minutes to revive them.
No Hershey bars? Chopped chocolate chips or chopped semi-sweet chocolate bars work in a bind, but the flavor won't be quite the same. Swapping heavy cream for half-and-half cuts richness but keeps the pie moist. For the oat topping, crushed graham crackers or pecans add fun texture variations. The cinnamon in the topping is optional, but trust me—it adds warmth that makes the whole pie sing. If you're making this ahead, assemble the pie but don't bake it—the filling keeps for 24 hours in the fridge before baking. Pro tip: line your pie dish with parchment for easy removal—this pie is so rich it'll slide right out.
This pie is a crowd-pleaser that reheats beautifully—just warm slices for 10 seconds in the microwave. Keeps 5 days in the fridge, fully set but still delicious. For parties, make it a day ahead and it'll taste even better as the flavors meld. Freezes for 3 months if you wrap it tightly in plastic and foil. The oat topping stays crisp if you reheat it covered with a damp paper towel. Serve with vanilla ice cream (or just eat it straight from the pie—no judgment here). Leftovers? They disappear fast, so make a backup slice.
Why You'll Love This Recipe
- No-Fuss Assembly: I swear, this pie comes together faster than I can say "chocolate fix." Melt butter, mix flour and sugar, layer in chopped Hershey bars, pour on the cream—boom. No rolling crusts, no fussing with layers. The only measuring I do is eyeballing the chocolate chunks, and honestly? No one notices.
- Rich Without Effort: That first bite of creamy, fudgy chocolate with a buttery crust? It’s like dessert got a shortcut to perfection. The heavy cream turns silky while the sugar caramelizes just enough to make every slice taste like a warm hug. I’ll be real: I’ve made it for people who "don’t like pie," and they still ask for seconds.
- Party or Pajamas: Bring this to a potluck and watch it disappear, or serve it with ice cream for a lazy Sunday night. The Hershey bars’ familiar sweetness makes it crowd-pleasing, but the crust’s buttery crunch elevates it past "just chocolate." Between us, I’ve even packed slices for work—no judgment.
- Budget Sweet Spot: A whole pie for under $10? With pantry staples like flour and sugar doing the heavy lifting, this is my go-to when I want to impress without breaking the bank. Leftovers? They’re even better the next day—if there are any. (Spoiler: There won’t be.)
Step-by-step instructions for Hershey bar pie recipe
This decadent pie delivers a perfect balance of crispy oat crown and molten chocolate center—every bite is pure indulgence.
Prepare the Crust and Chocolate Filling
Start by placing the 1 whole pre-baked pie crust on a baking sheet lined with parchment paper. In a medium bowl, whisk together the 1 cup unsalted butter (cold, cubed), 1.5 cups all-purpose flour, 0.5 cup granulated sugar, 0.5 tsp salt, and 0.5 tsp ground cinnamon until the mixture resembles coarse crumbs. Press this filling mixture firmly into the pie crust, creating an even layer about ¼-inch thick. This ensures the crust stays crisp while the chocolate melts beautifully underneath.
Next, chop the 12 oz Hershey milk chocolate bars into ½-inch pieces and set aside. In a separate bowl, whisk together the 2 whole large eggs, 1 cup heavy cream, and 1 tsp vanilla extract until smooth. Sprinkle the chopped chocolate pieces evenly over the crust, then pour the egg mixture over the chocolate. The chocolate will begin to soften slightly—this is normal and helps create that signature molten center when baked.
Assemble the Oat Crown Topping
In a food processor, pulse the 1.5 cups old-fashioned oats until they form fine crumbs. In a small bowl, combine the oat crumbs with 0.5 cup packed brown sugar, 0.5 cup melted butter, 0.5 tsp salt, and 0.5 tsp ground cinnamon. Mix until the oats are evenly coated and the mixture holds together when pressed. This topping is what gives the pie its signature crunchy crown—don’t skip blending the oats finely for that perfect texture.
Sprinkle the oat mixture evenly over the top of the pie, pressing down lightly to ensure it adheres to the crust. The oats should cover the entire surface, leaving no gaps. For an extra touch, you can use a fork to create a decorative pattern, but pressing firmly is more important for that satisfying crunch.
Bake to Golden Perfection
Preheat your oven to 350°F. Place the pie on the middle rack and bake for 45-50 minutes, until the oat topping is deep golden brown and the edges of the crust are lightly toasted. The center should still look slightly underdone—this is where the magic happens. The residual heat will finish melting the chocolate after you remove the pie from the oven.
Here’s the key: as soon as you take the pie out of the oven, let it rest for 10 minutes before slicing. This allows the chocolate to fully melt and the filling to set slightly, creating that perfect molten center. If you cut it too soon, the chocolate will run out, and you’ll miss the best part of this pie.
Serve Warm for Maximum Indulgence
Slice the pie into 8 equal wedges using a sharp knife, wiping the blade between cuts to ensure clean slices. Serve the pie warm—this is when the chocolate is at its most luxurious, gooey state. The contrast between the crispy oat crown, the flaky crust, and the molten chocolate filling makes every bite unforgettable.
For an extra touch, garnish each slice with a sprinkle of ground cinnamon or a drizzle of melted chocolate. Pair it with a scoop of vanilla ice cream for the ultimate dessert experience. This pie is best enjoyed within 2-3 hours of baking, so don’t wait—dig in while the center is still warm and gooey!
Pro Tips For Making Hershey Bar Pie
- MELT CHOCOLATE LOW: I learned this the hard way—heating chocolate bars directly over simmering water or in the microwave turns them grainy. Instead, chop the Hershey bars into small, even pieces and melt them in a heatproof bowl set over a pot of barely simmering water (about 170°F). Stir every 30 seconds until fully smooth—this keeps the texture silky and prevents seizing.
- CHILL THE CRUST: Skip the pre-baking step if you’re short on time, but chill the crust for at least 30 minutes before adding the filling. Cold butter in the crust prevents it from turning soggy when the warm chocolate-cream mixture hits it. (Yes, even if you’re impatient like me—trust the process.)
- WHISK HOT CREAM: The heavy cream in this pie needs to be hot (just off the boil) before mixing it into the chocolate-sugar base. Pouring it in slowly while whisking vigorously creates a stable, pudding-like texture instead of curdling. (Your future self will thank you for not skipping this.)
- USE COLD BUTTER: Don’t soften the unsalted butter for the crust—cut it straight from the fridge into the flour. Cold butter creates flakier layers, and since this pie isn’t baked long, you’ll get that buttery, crumbly texture without the crust turning greasy. (Does it look weird? Yes. Does it work? Every single time.)
Wine and beer pairings for this recipe
Rich Chocolate Wines
For this decadent pie, I always reach for a Cabernet Sauvignon with its bold tannins and dark fruit notes that stand up to the chocolate's intensity. A Napa Valley Cabernet like Caymus Vineyards or a more affordable Bogle Vineyards option offers the perfect balance.
The wine's acidity cuts through the richness, while its dark berry flavors complement the chocolate beautifully. 🍷
Creamy Dessert Whites
If you prefer white wine, a Chardonnay with noticeable oak and vanilla undertones works wonderfully. I love Kendall-Jackson Grand Reserve—its creamy texture and subtle buttery notes mirror the pie's richness.
For something lighter, a Viognier with its floral and stone fruit characteristics provides a refreshing contrast to the chocolate's depth.
Sweet Dessert Options
Don't overlook sweet dessert wines when serving this pie. A Moscato d'Asti from Italy offers a light, fizzy sweetness that cleanses the palate between bites. For something more robust, try a Port wine like Graham's Six Grapes—its caramel and dried fruit flavors enhance the chocolate experience.
Serve these chilled for the best effect.
Beer Pairings
For beer lovers, a Belgian-style dubbel with its malty sweetness and spiced notes creates an unexpected but delicious pairing. I recommend Westmalle Dubbel—its caramel and raisin flavors complement the chocolate beautifully.
Alternatively, a stout like Guinness provides a creamy texture that mirrors the pie's richness, while its roasted malt notes add depth.
Coffee Companion
No dessert pairing section would be complete without mentioning coffee. A dark roast with chocolate notes—like Peet's Major Dickason's Blend—enhances the pie's flavors. The coffee's bitterness balances the sweetness, creating a perfect harmony. Brew it strong and serve it alongside slices for the ultimate indulgence. ☕

Frequently asked questions
Can I make this pie without a pre-baked crust?
Yes, but it requires extra care. Use a 9-inch deep-dish pie crust and bake it for 12-15 minutes at 375°F before adding the filling. This prevents a soggy bottom. For best results, chill the unbaked pie in the fridge for 30 minutes before baking to help the crust hold its shape.
What if I don't have Hershey bars? Can I substitute?
Use 12 oz of chopped milk chocolate chips or semi-sweet chocolate bars instead. For a richer flavor, add 1 tablespoon of corn syrup to the egg mixture to help the chocolate melt more smoothly. The texture will be slightly different but still delicious.
Why does my pie's center stay hard instead of molten?
This usually happens if the pie bakes too long or the chocolate isn't chopped finely enough. The center should look slightly underdone when you remove it from the oven. For next time, reduce baking time by 5 minutes and chop the chocolate into ¼-inch pieces instead. Let it rest 10 minutes before slicing.
Can I make this pie ahead of time?
Yes! Assemble the pie (including the oat topping) and refrigerate it unbaked for up to 24 hours. Bake it straight from the fridge, adding 5-10 extra minutes to the baking time. The flavors will deepen overnight, and the texture will be even better. Just don't bake it ahead—always serve it warm for that gooey center.
How do I store leftovers?
Store leftovers in an airtight container in the fridge for up to 5 days. To reheat, cover a slice with a damp paper towel and microwave for 10-15 seconds. The oat topping will soften slightly but stay flavorful. For longer storage, freeze slices (without the oat topping) for up to 3 months—thaw overnight in the fridge.
