Ingredients for reese's peanut butter chips fudge
Pantry staples and a handful of candy bars—this fudge is all about rich swirls and melty perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Semi-Sweet Chocolate Chips 🍫 | 12 oz | High-quality, 60% cocoa preferred |
| Creamy Peanut Butter 🥜 | 1 cup | Natural or regular, no sugar-free |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat for best texture |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into pieces |
| Reese's Peanut Butter Chips 🍫🥜 | 12 oz | Crushed into small pieces |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Granulated Sugar 🍚 | ½ cup | Light brown sugar works too |
| Milk Chocolate Chips 🍫 | 6 oz | For extra creaminess |
| Vegetable Oil 🫒 | 1 tbsp | For greasing the pan |
The chocolate chips make or break this fudge. Hershey's Special Dark or Ghirardelli are my go-tos—they melt smoothly and taste incredible. Reese's Peanut Butter Chips? Grab the family-size bag from Costco or Trader Joe's—it's cheaper and lasts longer. For the peanut butter, Jif Natural or Skippy work perfectly, but avoid anything with added sugar if you're watching that. The heavy cream and butter need to be full-fat—this isn't the time for low-fat shortcuts. Trust me, it's worth the extra minute to check the labels and grab the good stuff.
No Reese's Peanut Butter Chips? Crushed Reese's Pieces in a pinch, but the texture won't be quite the same. Short on milk chocolate? Add an extra 6 oz of semi-sweet chips and skip it. The vanilla extract is non-negotiable—it's what ties all the flavors together. If you're out, vanilla bean paste works too, but pure extract is easier to find. For the crushed chips, pulse them in a food processor or smash them by hand with a rolling pin. Don't skip this step—those little chunks are what make this fudge taste like the candy bar you love.
This fudge sets up beautifully in the fridge. Line your pan with parchment paper for easy removal—no more scraping. It keeps for up to a week in the fridge, but honestly, it disappears faster than that. For gifting, wrap slices in wax paper and tie with a ribbon. Freezes for up to 3 months if you want to make it ahead. Just let it sit at room temperature for 10 minutes before slicing—it's firmer straight from the fridge and easier to cut that way.

Step-by-step instructions for Reese's peanut butter chips fudge recipe
Here's how to make this decadent fudge with rich swirls of peanut butter and chocolate—no fancy skills required.
Melt Chocolate and Butter Together
Line an 8x8-inch baking dish with parchment paper, leaving an overhang on two sides for easy removal. Grease the bottom lightly with the 1 tablespoon vegetable oil to prevent sticking. In a large microwave-safe bowl, combine the 12 ounces semi-sweet chocolate chips and 0.5 cup unsalted butter. Microwave in 20-second bursts, stirring between each interval, until completely melted and smooth. You'll know it's ready when the mixture reaches 110°F and has a glossy sheen.
This melting process is crucial—if the chocolate gets too hot, it can seize. Stirring between bursts prevents overheating and ensures even melting. Set the melted chocolate mixture aside for now; you'll use it to create the base layer of your fudge.
Mix Peanut Butter and Cream Base
In the same bowl, add the 1 cup creamy peanut butter, 1 cup heavy whipping cream, 0.5 cup granulated sugar, 1 teaspoon vanilla extract, and 0.25 teaspoon salt. Whisk vigorously until everything is fully combined and smooth. The mixture should be thick but pourable—like a rich peanut butter sauce. If it looks too thick, add 1 tablespoon of hot water to loosen it slightly.
Here's the thing—this is where the magic happens. The peanut butter needs to be fully incorporated to create that signature creamy texture. If you see any lumps, strain the mixture through a fine-mesh sieve to ensure a silky consistency. This step sets the foundation for your fudge's signature flavor and texture.
Layer and Swirl the Chocolate
Pour half of the peanut butter mixture into the prepared baking dish, spreading it evenly across the bottom. Sprinkle 6 ounces milk chocolate chips over the top, pressing them lightly into the peanut butter layer. Then, pour the remaining peanut butter mixture over the chocolate chips, spreading it evenly. Using a butter knife, gently swirl the mixture in a circular motion, creating marbled patterns throughout the fudge.
This layering technique is what gives the fudge its signature look and taste. The milk chocolate chips add extra creaminess and contrast the rich peanut butter flavor. Don't worry about making perfect swirls—just aim for an even distribution. The fudge will still taste amazing even if the swirls aren't perfect.
Add Crushed Reese's Chips and Set
Crush the 12 ounces Reese's peanut butter chips into small pieces using a rolling pin or food processor. Sprinkle the crushed chips evenly over the top of the fudge, pressing them down gently to ensure they stick. Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours, or until the fudge is completely set and firm to the touch.
Patience is key here. The longer you let it chill, the easier it will be to slice. If you're in a hurry, you can place the dish in the freezer for 2 hours, but don't skip the chilling step entirely—it's what makes the fudge slice cleanly and hold its shape. Once set, the fudge should have a glossy sheen and be firm enough to cut into perfect squares.
Cut and Serve
Once the fudge is fully set, remove it from the refrigerator and let it sit at room temperature for 5-10 minutes to soften slightly. Use the parchment paper overhang to lift the fudge out of the pan and place it on a cutting board. Cut into 12 equal squares using a sharp knife, wiping the knife between cuts to ensure clean edges. Serve immediately or store in an airtight container in the refrigerator for up to 1 week.
Each bite should deliver a perfect balance of rich peanut butter, creamy chocolate, and crunchy Reese's pieces. The fudge should be firm yet tender, with a glossy finish that's irresistible. Enjoy it as a dessert, gift it in pretty boxes, or share it with friends—this fudge is always a crowd-pleaser.
Pro Tips For Making Reese'S Peanut Butter Chips Fudge
- Temper the Peanut Butter: Warm that creamy peanut butter with the heavy whipping cream first—just until it’s smooth and slightly runny (about 2 minutes in a microwave, stirring every 30 seconds). Cold peanut butter fights the chocolate, and you’ll end up with a grainy mess instead of that perfect, velvety texture. Trust me, I’ve learned this the hard way after scraping chocolate off my fingers.
- Chop the Chips Small: Break those Reese’s peanut butter chips into tiny pieces—think rice-sized or smaller—before folding them in. Big chunks stay chewy and sink to the bottom like a fudge crime scene. If you’re lazy (like me), pulse them in a food processor for 10 seconds, but don’t overdo it—you want crunch, not peanut butter dust.
- Don’t Rush the Cool: Let the fudge sit in the pan for a full 10 minutes before cutting, even if it looks set. I used to impatiently slice into it at 5 minutes, only to have it slide off the parchment like a greased pig. The first cut is the hardest—wait, and you’ll get clean slices every time.
- Grease with Butter, Not Oil: Use a thin layer of melted butter (not oil) to coat your pan and parchment paper—it prevents sticking and adds a subtle richness. Butter’s fat content bonds better with the chocolate than oil ever will. (Yes, even if you’re in a hurry—just do it while the fudge cooks.)
Essential equipment for great reese's peanut butter chips fudge
Double Boiler Setup
You don’t need fancy equipment—just a heatproof bowl and a saucepan. I use a stainless steel mixing bowl (like the OXO Good Grips brand) that fits snugly over a saucepan filled with 1-2 inches of water.
This gentle, indirect heat melts the chocolate and peanut butter evenly without scorching. Avoid direct microwave melting for this step—it’s too easy to overheat and seize the chocolate. 🌡️
Mixing Tools
A heat-resistant silicone spatula (I love the OXO Good Grips version) is essential for scraping the bowl’s sides and ensuring no chocolate bits remain unmelted. For the peanut butter mixture, a whisk or hand mixer (like my KitchenAid KHM5221) saves time and effort.
If you’re straining the mixture, a fine-mesh sieve or chinois works best—just don’t skip this step if you see lumps!
Crushing Reese’s
For crushing the Reese’s Peanut Butter Chips, a rolling pin or food processor does the job. I prefer the rolling pin for small batches—it’s faster and gives you more control over the size of the pieces.
If using a food processor, pulse in 2-second bursts to avoid turning the chips into peanut butter paste. A Ziploc bag and a hammer also works in a pinch (just place chips in the bag and smash gently). 🥜
Baking Dish Essentials
An 8x8-inch baking dish is ideal, but any square or rectangular pan will work. Line it with parchment paper (I use Reynolds Non-Stick Parchment Paper) for easy removal. Grease the bottom lightly with vegetable oil or butter to prevent sticking.
Avoid non-stick spray—it can leave a residue that ruins the texture. For gifting, opt for a clear glass baking dish so guests can see the swirls!
Storage Containers
Store leftovers in an airtight container (like Rubbermaid Brilliance containers) to maintain freshness. For gifting, wrap slices in wax paper or parchment paper, then tie with a ribbon. If freezing, use quart-sized freezer bags—they’re stackable and prevent freezer burn. Label everything with the date to track freshness. ❄️
Optional Pro Upgrades
For a smoother finish, invest in a candy thermometer (like the Thermapen One) to monitor the chocolate’s temperature—it should never exceed 115°F. A bench scraper helps spread the fudge evenly in the pan, and a sharp chef’s knife ensures clean cuts.
If you’re making this often, a silicon spatula set (like Epicurean) is a game-changer for scraping and serving.
Nutrition facts
Frequently asked questions
Can I make this fudge without crushed Reese's Peanut Butter Chips?
If you don’t have the chips, use crushed Reese’s Pieces instead—they’ll give a similar flavor but with a finer texture. For a nut-free version, try crushed chocolate-covered almonds or mini marshmallows for sweetness. Just reduce the amount slightly since these ingredients have different moisture levels.
Why did my fudge turn out too soft or sticky?
Soft fudge usually means it didn’t chill long enough. Let it set for the full 4 hours (or overnight) in the fridge for perfect firmness. If it’s sticky after cutting, it may have absorbed too much moisture—store leftovers in an airtight container with a slice of bread to absorb excess dampness. For next time, ensure your chocolate and butter are fully melted but not overheated.
How do I store this fudge for maximum freshness?
Keep it refrigerated in an airtight container for up to 1 week. For longer storage, freeze slices in a freezer bag for up to 3 months. To serve, let frozen fudge sit at room temperature for 10-15 minutes before slicing. Avoid leaving it out too long—humidity can make it soggy.
Can I use powdered peanut butter instead of creamy?
Not recommended! Powdered peanut butter lacks the richness and fat content needed for proper texture. If you must substitute, use 1 extra tablespoon of oil per cup of powdered peanut butter to mimic the creaminess. However, the flavor and mouthfeel won’t be the same—creamy peanut butter is the secret to that signature smoothness.
What’s the best way to gift this fudge?
Wrap individual squares in wax paper or parchment paper, then tie with a ribbon for a polished look. Place them in a clear cellophane bag with a handwritten tag for an elegant touch. For bulk gifting, use a wooden box or decorative tin—just ensure the container is airtight to preserve freshness.
