Ingredients for reese's peanut butter chips fudge
Six simple ingredients transform into velvety fudge with pockets of peanut butter magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweetened Condensed Milk 🥛 | 1 can | 14 oz can, unopened for best texture |
| Unsalted Butter 🧈 | 1 cup | Full-fat, cut into pieces for even melting |
| Semi-Sweet Chocolate Chips 🍫 | 1 cup | High-quality, 60% cacao preferred |
| Reese's Peanut Butter Chips 🥜 | 1 cup | Whole chips, not melted or pre-shredded |
| Cream of Tartar 🧂 | 1 ½ tsp | Essential for smooth, creamy texture |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality vanilla preferred |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Fine grain, for subtle seasoning |
| Heavy Whipping Cream 🥛 | ½ cup | Cold, full-fat for stability |
The sweetened condensed milk is non-negotiable—it’s the backbone of that silky texture. Grab the 14 oz can (not the little ones) from the baking aisle at Walmart or Target, where they’re usually stocked near the coffee. If you’re feeling fancy, Trader Joe’s carries organic versions, but the regular stuff works perfectly. The butter should be unsalted (salted throws off the balance) and full-fat—none of that low-fat nonsense. For chocolate, Ghirardelli or Goya chips are my go-tos, but any good-quality semi-sweet will do. And the Reese’s peanut butter chips? Whole, not melted—this ensures they stay distinct pockets in the fudge. The cream of tartar is the secret weapon here; it stabilizes the mixture so it doesn’t seize up. You can find it in the baking section or near the spices at most grocery stores.
No Reese’s peanut butter chips? Crushed Reese’s cups work in a pinch (just melt them first), or peanut butter cups chopped into small pieces. Short on chocolate chips? Melted chocolate bars (like Hershey’s Special Dark) will do, but toss in a few extra chips if you’re worried about texture. The vanilla extract can be swapped for vanilla bean paste if you’re feeling extra, but pure extract is fine. If you’re avoiding dairy, coconut cream replaces the heavy whipping cream, but the texture will be slightly lighter. Pro tip: Toast your peanut butter chips for 2 minutes in the microwave before mixing—they’ll crisp up slightly and add an extra layer of flavor. And if you’re making this for a crowd, double the batch but use two 8x8-inch pans for even setting.
This fudge sets in the fridge like magic—30 minutes max if you’re patient, but I usually let it sit for 1 hour to be safe. Store it in an airtight container for up to 1 week, though it’s rare to have leftovers. For gifting, wrap portions in parchment paper and tie with twine—it looks adorable and keeps the fudge fresh. The cream of tartar trick means it won’t get grainy over time, so you can freeze portions for up to 3 months if you’re prepping ahead. And if you’re feeling fancy, dust the top with powdered sugar or crushed peanuts before serving. Trust me, it’s worth the extra minute.

Step-by-step instructions for Reese's peanut butter chips fudge
Here's the straightforward, foolproof method for creamy, no-bake fudge with perfect Reese's chunks.
Melt the Butter and Condensed Milk
In a medium saucepan, combine the 1 cup unsalted butter and 1 can sweetened condensed milk. Place over medium-low heat and stir gently until the butter melts completely and the mixture begins to simmer. This should take about 5-7 minutes—watch closely so it doesn't boil over.
Once simmering, reduce heat to low and let it cook for 2-3 minutes until the mixture thickens slightly but isn't boiling. The texture should resemble thick syrup. Here's the thing—don't walk away. Boiling causes sugar crystals to form, ruining that silky texture we're after.
Incorporate the Cream of Tartar and Salt
Remove the saucepan from heat and stir in the 1.5 teaspoons cream of tartar and 0.25 teaspoon diamond crystal kosher salt. This is where the magic happens—the cream of tartar prevents sugar crystallization, giving you that professional fudge texture. Whisk vigorously for 1 minute until fully dissolved.
Return the pan to low heat and let it cook for another 2-3 minutes, stirring constantly. You're looking for the mixture to reach 234°F on a candy thermometer—this is the soft-ball stage. If you don't have a thermometer, test by dropping a small amount in cold water—it should form a soft ball that holds its shape when cooled.
Add Chocolate Chips and Vanilla
Immediately remove the pan from heat and stir in the 1 cup semi-sweet chocolate chips and 1 teaspoon vanilla extract. Work quickly—chocolate cools fast. Let the mixture sit for 1-2 minutes while the chocolate melts completely. If it thickens too much, return to low heat for 10-15 seconds just to loosen it.
Here's where it gets fun—toss in the 1 cup Reese's peanut butter chips. Fold them in gently so they stay whole. The contrast between the creamy fudge and crunchy peanut butter chunks is what makes this recipe special. Don't worry if they don't all melt—they'll soften just enough to create pockets of gooey peanut butter goodness.
Whip in the Heavy Whipping Cream
Let the mixture cool slightly for 2-3 minutes until it's warm to the touch but not hot. Then, using a stand mixer or hand mixer, beat in the 0.5 cup cold heavy whipping cream on medium-high speed for 3-4 minutes. You're looking for the fudge to thicken and become smooth and glossy—almost like pudding.
This is the moment that matters: the fudge should coat the back of a spoon and hold its shape when you lift it. If it's too thin, whip for another 30 seconds. If it's too thick, you can gently reheat it for 10 seconds to loosen it slightly. The cream adds that signature lightness that makes this fudge irresistible.
Set and Enjoy
Quickly pour the fudge into a 9x9-inch greased pan or lined loaf pan. Smooth the top with a spatula and let it cool at room temperature for 1 hour. Then, refrigerate for 2-3 hours until firm. This chilling step is crucial—it develops the perfect snap when you cut it.
Once set, cut into squares or diamonds with a sharp knife. The fudge should hold its shape but still be soft enough to melt slightly in your mouth. Store in an airtight container in the fridge for up to 1 week—though I doubt it'll last that long. Serve with a sprinkle of extra Reese's chips on top for that extra wow factor.
Pro Tips For Making Reese'S Peanut Butter Chips Fudge
- Stir Constantly, Low Heat: This isn’t candy thermometer territory—you’re aiming for a slow, steady simmer where the mixture thickens like honey, not burns like a forgotten pot of oatmeal. After the cream of tartar kicks in (around 5 minutes), reduce to the lowest heat that keeps gentle bubbles going. I used to rush it, and the fudge would either seize up or taste bitter—now I treat it like a lazy Sunday morning.
- Chop Peanut Butter Chips: Whole Reese’s chunks? Too lazy. Roughly chop the peanut butter chips into quarters before folding them in—this ensures even distribution and melty pockets in every bite. (Yes, even if you’re impatient like me.) If you’re feeling fancy, toast the chopped pieces for 30 seconds in the microwave first—the peanut butter flavor sings louder.
- Don’t Overmix After Cooling: The moment you pour the fudge into the pan, resist the urge to poke or prod it while it sets. Overmixing after cooling turns rich, creamy fudge into a dense, grainy mess. Let it rest 10 minutes first, then cut it with a warm knife—it’ll release cleanly. Trust me, your future self will stop staring at a lumpy disaster.
- Use Real Cream of Tartar: That “cream of tartar substitute” (like lemon juice or vinegar) you found online? Skip it. The acidity in cream of tartar is the only thing that prevents graininess in this recipe—it’s the unsung hero that makes the texture silky. Measure it carefully (½ tsp is non-negotiable), or you’ll end up with fudge that tastes like it’s fighting a losing battle.
Dietary considerations for this reese's peanut butter chips fudge
Gluten-Free Adaptations
This fudge is naturally gluten-free since it relies on dairy, chocolate, and peanut butter—no flour or grains involved! The key is ensuring all your ingredients are certified gluten-free. I always double-check my sweetened condensed milk (like Eagle Brand) and chocolate chips (Enjoy Life brand is my go-to) for gluten-free labels.
The cream of tartar and vanilla extract are typically safe, but brands like McCormick explicitly label their products gluten-free.
Dairy-Free Swaps
For a dairy-free version, replace the butter and heavy whipping cream with equal parts coconut oil and coconut cream. Use 1 cup coconut oil (melted) instead of butter, and ½ cup coconut cream (chilled overnight) instead of heavy cream.
The texture will be slightly lighter but still rich. I’ve tested this swap and found that adding 1 extra tablespoon of vanilla extract helps balance the coconut flavor.
Nut-Free Alternatives
If peanut allergies are a concern, skip the Reese’s peanut butter chips and replace them with chopped pretzels (for saltiness) or crushed potato chips (for crunch). For a sweeter alternative, use mini marshmallows or white chocolate chips.
The key is maintaining texture contrast—something crunchy or chewy keeps the fudge interesting. I’ve even used toasted coconut flakes for a tropical twist that still feels indulgent.
Vegan Options
To make this fudge vegan, swap the butter and heavy cream for coconut oil and coconut cream, and use vegan chocolate chips (like Pascha or Enjoy Life brands).
The cream of tartar can be replaced with 1 teaspoon lemon juice, which serves the same purpose of preventing sugar crystallization. For extra richness, add 1 tablespoon maple syrup to the mixture. The result is still creamy but with a subtly earthy coconut note.
Lower Sugar Versions
If you’re watching sugar intake, reduce the sweetened condensed milk to ½ can and replace the other ½ can with unsweetened applesauce or Greek yogurt. Cut the chocolate chips to ½ cup and add 1 teaspoon cinnamon for warmth.
The texture will be slightly less dense, but the flavor remains satisfying. I’ve also used monk fruit sweetener (like Lakanto) mixed with a little water to replace half the condensed milk, though the results are best when balanced with a touch of honey.
Keto-Friendly Adjustments
For a keto version, replace the sweetened condensed milk with ½ cup powdered erythritol (like Swerve) mixed with ½ cup heavy cream and 2 tablespoons unsweetened almond milk. Use ½ cup sugar-free chocolate chips (like Lily’s) and ½ cup chopped pecans or walnuts instead of Reese’s chips.
The cream of tartar can be omitted since sugar crystallization isn’t an issue with erythritol. The result is a lower-carb, high-fat fudge that’s still decadent—just be sure to chill it longer for a firmer set.

Frequently asked questions
Why does this fudge need cream of tartar?
The cream of tartar prevents sugar crystals from forming, which keeps your fudge silky smooth instead of grainy. Without it, you risk ending up with a texture more like sand than dessert. It's the secret ingredient that makes this recipe foolproof every time.
Can I use regular peanut butter instead of Reese's chips?
Not recommended! Reese’s peanut butter chips provide that signature peanut butter cup flavor in distinct pockets. If you must substitute, try crushed Reese’s cups (melted first) or peanut butter cups chopped into small pieces. Regular peanut butter will make the fudge too dense and lose that special texture contrast.
What if my fudge didn't set properly?
If your fudge is too soft after chilling, it likely didn't reach the proper 234°F temperature. For next time, use a candy thermometer or test by dropping a bit in cold water—it should form a soft ball. If it's already made, return it to low heat for 1-2 minutes to thicken slightly, then chill again.
How do I store leftovers without them sticking?
Line your storage container with parchment paper before adding the fudge, then cover with another sheet. This prevents sticking and makes slicing easier. Store in the fridge for up to 1 week. For longer storage, wrap individual portions in plastic wrap and freeze for up to 3 months.
Can I make this fudge without a mixer?
Yes! If you don't have a mixer, vigorously whisk the heavy cream into the fudge mixture by hand for 5-7 minutes until it thickens. You'll need strong arms, but it's doable. For extra insurance, use a hand whisk and work in a bowl over an ice bath to keep the mixture cool while you whip.
