Ingredients for molly yeh peanut butter fudge pie
Eight ingredients transform into a showstopping pie—rich peanut butter, velvety chocolate, and a crisp crust that holds it all together.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted, plus extra for dusting |
| Granulated Sugar 🍚 | ½ cup | For crust, plus extra for sprinkling |
| Light Corn Syrup 🍯 | ½ cup | For gooey texture |
| Creamy Peanut Butter 🥜 | 1 ½ cups | Natural, no added sugar |
| Dark Chocolate Chips 🍫 | 1 cup | Semi-sweet, 60% cocoa |
| Large Eggs 🥚 | 1 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality |
| Salted Peanuts 🥜 | ½ cup | Chopped, for crunch |
| Powdered Sugar 🍚 | ¼ cup | For dusting |
| Baking Powder 🍞 | ½ tsp | For crust lift |
| Ground Cinnamon 🌿 | ½ tsp | Optional, for warmth |
The peanut butter is non-negotiable—natural, no-sugar-added is a must for authentic flavor. Jif Natural or Smucker's are my go-tos, but any creamy kind works. The dark chocolate chips? Ghirardelli or Ghirardelli 60% melt beautifully, but don’t skimp on quality here. The crust’s secret? Cold butter for flaky layers, and I always sift the flour to avoid lumps. If you’re in a rush, King Arthur Flour’s pre-sifted bags save time.
No corn syrup? Maple syrup works in a pinch—just reduce the filling by 2 tbsp to account for moisture. Swapping chocolate? Dutch-process cocoa powder plus 1/4 cup butter mimics the richness, but texture will differ slightly. Chopping peanuts? Food processor or pulse in a blender for even bits. For extra decadence, fold in 1/4 cup chopped walnuts with the peanuts. And if you’re gluten-free, Bob’s Red Mill 1:1 flour keeps the crust intact.
This pie reheats beautifully—just 30 seconds in the microwave restores that gooey magic. Store leftovers in the fridge for 4-5 days, but honestly, it’s best the day it’s made. For make-ahead magic, assemble the pie, chill 4 hours, then bake. The crust stays crisp, and the filling sets perfectly. Freeze unbaked pies for up to 3 months—thaw overnight in the fridge before baking.

Step-by-step instructions for Molly Yeh's peanut butter fudge pie
Here's how to create this legendary nutty-sweet masterpiece with a perfect crumbly crust and gooey center.
Craft the Ultimate Crust
In a food processor, pulse the 1 cup unsalted butter (cold, cubed) with the 1.5 cups all-purpose flour, 0.5 cup granulated sugar, 0.5 tsp baking powder, and a pinch of salt until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. I like to press the butter pieces between my fingers to check - they should hold their shape but still feel slightly soft.
Transfer the mixture to a pie dish and press firmly and evenly into the bottom and up the sides, creating a thick crust about ¼-inch thick. Use your fingers or a flat-bottomed glass to smooth the edges. Chill in the refrigerator while you prepare the filling - this prevents shrinking during baking. The crust should look uniformly packed with no gaps where filling might leak through.
Prepare the Filling
In a medium saucepan, combine the 1.5 cups creamy peanut butter, 0.5 cup light corn syrup, 1 whole large egg, and 1 tsp vanilla extract. Whisk constantly over medium-low heat until smooth and fully incorporated - about 3-4 minutes. The mixture should thicken slightly and become glossy, almost like a rich peanut butter glaze.
Remove from heat and stir in the 1 cup dark chocolate chips until completely melted and evenly distributed. Let the filling cool for 10 minutes while you preheat your oven to 350°F. The filling should be thick enough to hold its shape when dropped from a spoon but still pourable. If it's too thick, whisk in 1-2 teaspoons of hot water to loosen it.
Assemble and Bake
Pour the cooled filling into the chilled pie crust, spreading it evenly. Sprinkle the 0.5 cup chopped salted peanuts and 0.25 cup powdered sugar over the top, pressing gently to help them adhere. Bake for 45-50 minutes until the center is just set but still slightly jiggly - it should look like a thick fudge rather than a firm cake.
Here's the key: the center should wobble slightly when the pie is done. If it's fully set, it's overbaked. The edges should be golden brown while the center remains rich and glossy. This gooey texture is what makes this pie legendary - don't rush this step!
Cool and Finish
Remove from the oven and let the pie cool completely at room temperature for 2 hours. This slow cooling process allows the filling to set properly while maintaining that perfect fudge-like texture. I know it's tempting to cut into it sooner, but patience here makes all the difference.
Once fully cooled, refrigerate for at least 4 hours (or overnight) to enhance the flavors and textures. The contrast between the cool crust and warm, gooey center is what makes this pie truly magical. When ready to serve, dust with an additional sprinkle of powdered sugar and ground cinnamon for that final touch of warmth and sweetness.
Pro Tips For Making Molly Yeh Peanut Butter Fudge Pie
- Whisk Butter Slowly: If you dump cold butter into the sugar mix and start whisking like you’re trying to win a race, you’ll end up with a grainy, uneven filling. Instead, cut the butter into small cubes and add them one tablespoon at a time while whisking constantly—this way, the sugar dissolves smoothly and the texture stays silky. (Yes, it takes longer, but the pie won’t taste like sandpaper.)
- Use Warm Peanut Butter: Cold peanut butter clumps and fights you when mixing, especially in a hot filling. Scoop it straight from the jar and let it sit at room temperature for 10 minutes before adding it to the sugar-butter mixture. If you’re in a rush, microwave it for 15 seconds—just don’t overdo it, or you’ll end up with separated oil.
- Bake Until the Center Jiggles: The pie’s done when the edges are set but the center still wobbles slightly—like a firm Jell-O. If you pull it out too early, it’ll stay gummy; too late, and it’ll crack. Test it by gently pressing the center: it should spring back slowly, not bounce like a trampoline. (And for the love of peanut butter, don’t open the oven door early—condensation is the enemy.)
- Chill Before Slicing: This isn’t a pie you want to cut into right after baking. Let it cool completely at room temperature, then refrigerate for at least 4 hours (or overnight if you’re patient). The filling firms up beautifully, and the crust holds together—no crumbly mess when you serve slices. (I learned this after serving a wobbly, sad pie to guests. Never again.)
Creative variations of this molly yeh peanut butter fudge pie
Vegan Adaptations
Swap the egg for 1 tbsp ground flaxseed mixed with 3 tbsp water—let it sit for 5 minutes to thicken. Use Earth Balance vegan butter and King Arthur gluten-free flour blend for the crust.
For the filling, replace the egg with 2 tbsp aquafaba (chickpea brine) to bind the peanut butter and chocolate. The texture stays rich and gooey, just like the original! 🌱
Gluten-Free Twist
Replace all-purpose flour with 1.5 cups gluten-free 1:1 baking flour (like Bob’s Red Mill) and add ¼ cup cornstarch to the crust for structure. For the filling, ensure your peanut butter is certified gluten-free—Jif Natural or Smucker’s Natural are safe choices.
The crust may be slightly crumbly, but it still holds up beautifully. 🥜
Spiced Variations
Add ½ tsp cinnamon and ¼ tsp cayenne pepper to the filling for warmth. For a deeper flavor, fold in 1 tbsp espresso powder—it enhances the chocolate and peanut butter notes.
Top with crushed graham crackers instead of peanuts for a nut-free option. The spices make this pie feel cozy and festive. 🌶️
White Chocolate Swap
Replace dark chocolate chips with 1 cup white chocolate chips (like Guittard) for a sweeter, creamier filling. The texture remains gooey, but the flavor becomes lighter and more decadent.
Pair with toasted coconut flakes on top for a tropical twist. This version is perfect for those who prefer milder sweetness. 🥥
No-Bake Option
Skip the crust entirely and use a graham cracker crust (20 crackers, crushed) or a Nutella-stuffed crust for a no-bake version. Chill the filling for 4 hours before slicing—it’ll set like a cheesecake but with all the peanut butter fudge magic.
Great for hot days or when you’re short on time! ❄️
Protein Boost
Stir ¼ cup powdered peanut protein (like Naked Pea) into the filling for a protein-packed twist. The texture stays smooth, but you’ll get an extra 10 grams of protein per serving.
Top with chopped almonds for crunch. This version is ideal for post-workout treats or health-conscious dessert lovers. 💪

Frequently asked questions
Why does Molly Yeh's recipe use corn syrup in the filling?
The corn syrup creates that signature gooey, fudge-like texture by preventing the filling from setting too quickly. It also helps balance the richness of the peanut butter and chocolate, keeping the center soft and creamy. Without it, the pie might taste too dry or overly sweet.
Can I make this pie ahead of time?
Assemble the pie and refrigerate it 4 hours before baking for a firmer crust. After baking, let it cool completely, then refrigerate for 2-3 days—the flavors deepen over time. For best results, serve chilled, as the cold temperature enhances the gooey contrast.
What's the secret to the perfect crust texture?
Keep the butter cold when mixing and press the crust evenly into the pie dish. Chill it for 30 minutes before adding the filling to prevent shrinking. The key is a ¼-inch-thick layer—thicker crusts stay crisp, while thinner ones can become soggy.
How do I fix an overbaked pie?
If the center is too firm, try reheating slices in the microwave for 10-15 seconds to restore some gooeyness. For a backup, blend leftover pie with ½ cup whipped cream and serve as a decadent trifle. The flavor is still delicious—just adjust your baking time next time!
Can I substitute powdered peanut butter?
Not recommended—powdered peanut butter lacks the moisture and richness needed for the filling. If you must use it, add 2 tbsp water or milk to compensate, but the texture may be drier. Stick with creamy peanut butter for that authentic, velvety result.
