Ingredients for molly yeh peanut butter fudge pie
Eight-ingredient layers of crunch and creaminess—this pie is pure magic.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for even texture |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| Granulated Sugar 🍚 | ¾ cup | For crust sweetness |
| Large Egg 🥚 | 1 whole | Cold, for binding |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Creamy Peanut Butter 🥜 | 2 cups | Natural, no added sugar |
| Powdered Sugar 🍚 | 1 ½ cups | For peanut butter layer |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for best texture |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cocoa for fudge layer |
| Semi-Sweet Chocolate Chips 🍫 | ½ cup | For fudge balance |
| Vegetable Shortening 🧈 | ½ cup | For fudge stability |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Milk 🥛 | ¼ cup | For fudge consistency |
The peanut butter is non-negotiable here—Jif Natural or Skippy Creamy are my go-tos, but any brand without added sugar works. The chocolate chips? Ghirardelli 70% dark and Hershey's Semi-Sweet are my staples, but store brands are fine if they're high-quality. For the crust, King Arthur flour gives the best texture, but any all-purpose will do. If you're short on butter, vegetable shortening keeps the crust flaky without adding moisture. The secret to the fudge layer? Melting the chocolate slowly—microwave in 30-second bursts to avoid burning.
No peanut butter? Almond butter or tahini works in a pinch, though the flavor changes. Short on powdered sugar? Granulated sugar blended into a powder in a food processor gets you close. The crust can be made ahead and frozen—just thaw before adding fillings. For a vegan version, swap butter for vegan butter and use flax eggs. The heavy cream is crucial—whipping cream with 36% fat gives the best texture, but full-fat works too. If you're making this ahead, assemble the pie and refrigerate overnight—the flavors meld beautifully.
This pie keeps for 5 days in the fridge, but honestly? It disappears faster than that. The peanut butter layer softens when sliced, so serve it chilled. For extra shine on the fudge layer, brush with a little milk or cream before serving. Freezes beautifully for up to 3 months—just thaw in the fridge overnight. The crust stays crisp, and the fillings thaw perfectly. Leftovers? Warm slices in the microwave for 10 seconds to bring back that creamy texture.

Step-by-step instructions for molly Yeh's peanut butter fudge pie recipe
This decadent pie combines a buttery crust with layers of peanut butter and rich chocolate fudge—every step ensures that perfect balance of nutty, sweet, and creamy textures.
Prepare the Crust for a Perfect Base
In a large mixing bowl, combine the 2.5 cups all-purpose flour, 0.75 cup granulated sugar, 0.5 tsp salt, and cut the 1 cup unsalted butter into small cubes. Using a pastry cutter or your fingers, work the butter into the dry ingredients until the mixture resembles coarse crumbs with pea-sized butter pieces remaining.
Add the 1 whole large egg, 1 tbsp vanilla extract, and 0.25 cup milk. Mix gently with a fork until the dough just comes together—don't overwork it. Press the dough into a 9-inch pie dish, crimping the edges neatly. Chill in the refrigerator for 30 minutes while you prepare the filling. This step is crucial for a sturdy crust that won't shrink during baking.
Create the Peanut Butter Layer for Rich Flavor
In a medium saucepan, combine the 2 cups creamy peanut butter and 1.5 cups powdered sugar. Cook over medium-low heat, stirring constantly with a wooden spoon until the mixture is smooth and reaches 160°F—about 10 minutes. Remove from heat and let cool slightly, then stir in 1 cup heavy whipping cream until fully incorporated. Pour this warm peanut butter mixture into the chilled pie crust.
Spread evenly using an offset spatula, creating a smooth layer that reaches just below the crust's edge. The warmth of the peanut butter will help it set beautifully as the fudge layer cools. Let the peanut butter layer cool completely in the refrigerator for at least 1 hour before adding the fudge—this prevents melting during assembly.
Make the Chocolate Fudge Layer for Ultimate Decadence
In a microwave-safe bowl, combine the 1.5 cups dark chocolate chips, 0.5 cup semi-sweet chocolate chips, and 0.5 cup vegetable shortening. Microwave in 30-second intervals, stirring between each, until the mixture is completely melted and smooth—about 1 minute total. Stir in 1 cup heavy whipping cream and 1 tbsp vanilla extract until fully blended. The mixture should be thick but pourable.
Pour the chocolate fudge over the cooled peanut butter layer, spreading it evenly with a spatula. The contrast between the creamy peanut butter and rich chocolate creates the signature flavor profile. Place the pie back in the refrigerator and let it set for at least 2 hours, or until the fudge layer is firm to the touch. Patience here ensures clean slices and perfect texture.
Bake the Crust for a Golden Finish (Optional but Recommended)
Preheat your oven to 375°F. If you want a crispy crust, bake the unbaked pie (with both layers) for 12-15 minutes until the edges are golden brown and the crust is set. Watch closely after 10 minutes to prevent over-browning. For a softer crust, skip this step and serve the pie chilled straight from the refrigerator.
Let the pie cool completely before slicing—this allows the layers to fully set and makes for cleaner cuts. The final result should have a buttery crust, a creamy peanut butter layer, and a glossy chocolate fudge topping that melts slightly when cut. Serve with a dollop of whipped cream or a sprinkle of crushed peanuts for extra indulgence!
Pro Tips For Making Molly Yeh Peanut Butter Fudge Pie
- Chill the Dough: This isn’t optional—after mixing the crust, pop it in the fridge for at least 30 minutes. I learned this the hard way when my first attempt got greasy and tough. Cold butter behaves better, and the layers stay crisp instead of turning into a sad, flaky disappointment.
- Measure Butter Cold: Use a kitchen scale and scoop the butter straight from the fridge—no softening. Packed cold butter gives you that signature flaky texture in the crust. If you’re in a rush, at least let it sit in the freezer for 10 minutes before measuring. Trust me, your crust will thank you.
- Whisk the Egg Like Your Life Depends on It: Beat that large egg until it’s pale, thick, and ribbon-like before folding it into the filling. A lazy whisk means a dense, gummy pie. I used to skip this, and the result was more pudding than fudge. Take the extra 30 seconds—it’s worth it.
- Skip the Overmixing: Once the flour and sugar are combined, stop mixing the moment the dough clumps together. Overworking it develops gluten and turns the crust into a chewy mess. Fold just until it holds, then let the butter do the work. Your future self will notice the difference.
Essential equipment for perfect results
Pie Dish Essentials
The heart of this recipe starts with a 9-inch pie dish—I recommend a ceramic or glass dish for even heat distribution. Avoid dark-colored metal dishes, as they can cause uneven baking.
A deep-dish pie plate works best for holding the layers without spilling. For an extra-professional touch, I use a Wilton pie dish—it has a gentle lip that makes slicing easier. 🧑🍳
Mixing Tools
You’ll need a pastry cutter or your fingers for the crust, but a wooden spoon is essential for stirring the peanut butter mixture to prevent scorching. A medium saucepan with sloped sides helps with even heating.
For spreading layers smoothly, an offset spatula is a game-changer—it gives you precision without tearing the crust. A digital thermometer ensures your peanut butter reaches the perfect 160°F without burning. 🌡️
Chocolate Melting Gear
Melting chocolate properly is key, so a microwave-safe bowl (I use Pyrex) is a must. Stirring between 30-second bursts prevents overheating, and a heatproof silicone spatula makes blending easier. For the fudge layer, a small whisk helps incorporate the cream smoothly.
If you’re worried about chocolate seizing, keep a small bowl of hot water nearby to dip your whisk in between stirs. 🍫
Refrigeration Must-Haves
This pie relies on proper chilling, so a large baking sheet helps cool the crust quickly before adding fillings. A wire rack elevates the pie for even airflow, preventing sogginess.
For long-term storage, airtight containers (like Rubbermaid or Glasslock) keep the layers intact for up to 5 days. If freezing, parchment paper between layers prevents sticking. ❄️
Optional Upgrades
For a golden crust, a pastry brush lets you apply egg wash for extra shine. A pie server with a serrated edge makes clean slices effortless. If you love garnishes, crushed peanuts or whipped cream add texture—just store them in small jars with airtight lids.
A stand mixer isn’t required, but it speeds up blending the peanut butter layer if you’re making multiple pies. 💡

Frequently asked questions
Can I make this pie without a food processor or pastry cutter?
For the crust, you can use your fingers or a fork to cut butter into flour until pea-sized pieces remain. Just work quickly to avoid melting the butter. For the peanut butter layer, a sturdy wooden spoon works perfectly—just stir constantly over medium-low heat to prevent scorching.
Why does my peanut butter layer get grainy?
Graininess usually means the peanut butter wasn't heated enough or cooled too quickly. Always bring the mixture to 160°F and let it cool slightly before adding cream. Stir vigorously while cooling to maintain smoothness. If it's already grainy, blend briefly with an immersion blender to restore creaminess.
How do I prevent the fudge layer from cracking too much?
Cracking is normal, but for fewer cracks, ensure your chocolate is fully melted and the mixture is thick but pourable. Let the pie set in the fridge for at least 2 hours before slicing. If cracks appear too early, return it to the fridge for another hour. The cracks actually enhance flavor by concentrating the chocolate aroma!
Can I use almond butter instead of peanut butter?
Yes, but expect a different flavor profile. Almond butter works best in a 1:1 ratio, though it's slightly less sweet and has a more delicate taste. For balance, add 1 extra tablespoon of vanilla extract and consider reducing powdered sugar by 2 tablespoons. The texture remains similar, but the nutty depth changes.
How long does this pie keep in the freezer?
This pie freezes beautifully for up to 3 months when properly wrapped. Wrap the entire pie dish tightly in plastic wrap, then place in a freezer bag. Thaw overnight in the fridge—never at room temperature. The crust stays crisp, and the fillings thaw perfectly without losing texture.
