Just two ingredients turn into a creamy, melt-in-your-mouth fudge, no oven and no candy thermometer required. There’s a smooth white chocolate and peanut butter base poured into a pan and chilled until it’s firm enough to slice into neat squares.

Melting white chocolate chips, stirring in peanut butter until completely combined, and pouring the mixture into a lined pan is most of the process here. A long chill in the refrigerator is all that’s left before this fudge is ready to lift out and slice.

Creamy, rich, and gently sweet, this fudge is a satisfying no-bake treat for a holiday dessert tray, a bake sale, or any time a simple peanut butter fudge sounds appealing.

Why This Recipe Works

Melting white chocolate chips and stirring in peanut butter creates a smooth, rich fudge base without any cooked sugar syrup or candy thermometer involved, since the two melt and blend together easily and firm up on their own as the mixture cools and chills. Stirring the peanut butter in completely, rather than swirling it on top, gives this fudge an even, uniform color and flavor throughout every square.

Because white chocolate and peanut butter are both soft and pourable while warm, this combining technique works without any special equipment, just a microwave, a bowl, and a spoon.

Why Gentle Melting Matters

Melting the white chocolate slowly, in short bursts with a stir between each, rather than microwaving it all at once, is what keeps it smooth instead of grainy or seized. White chocolate scorches more easily than milk or dark chocolate, so a little extra patience here makes a real difference in the finished fudge.

What You’ll Need

• 3 cups (510g) white chocolate chips
• ¾ cup (190g) creamy peanut butter

You’ll also need an 8-inch square pan lined with parchment paper. This recipe makes about 16 squares.

A Note on Ingredient Choices

Good-quality white chocolate chips, rather than a white confectionery coating, melt more smoothly and give a richer, more authentic flavor to the finished fudge. A standard creamy peanut butter, rather than a natural, oil-separated style, stirs in more evenly and sets up into a firmer fudge.

Equipment You’ll Need

A microwave, a microwave-safe bowl, a sturdy spoon, and an 8-inch square pan lined with parchment paper are all you need; no oven required.

How to Make It

1. Prep. Line an 8-inch square pan with parchment paper.
2. Melt. Place the white chocolate chips in a microwave-safe bowl and heat in 20-second intervals, stirring between each interval until smooth.
3. Combine. Add the peanut butter and stir until completely combined.
4. Pour. Pour the mixture into the prepared pan and smooth the top.
5. Chill. Refrigerate for 2–3 hours, until completely firm.
6. Lift and slice. Lift the fudge out of the pan and cut into small squares.
7. Store. Store in an airtight container in the refrigerator.

Getting a Fully Smooth Base

Stirring the peanut butter into the melted white chocolate thoroughly, until no streaks remain, gives this fudge its signature smooth, even texture and pale, uniform color. A few extra stirs at this stage make a noticeable difference in how smoothly the fudge slices once chilled.

Getting an Even Layer

Pouring the fudge mixture into the pan and smoothing it with an offset spatula, working from the center outward, helps it settle into a level, even layer. An uneven base layer can make the finished squares look lopsided once the fudge is sliced.

Knowing When It’s Done

This fudge is ready to slice once it feels completely firm throughout, with no soft or tacky spots left in the center of the pan. If the middle still feels slightly soft after 3 hours, give the pan more time, checking every 30 minutes until it firms up fully.

Tips for Perfect White Chocolate Fudge

Stirring the peanut butter in while the white chocolate is still warm, rather than letting it cool first, helps the two combine into a smooth, lump-free mixture more easily. Letting the fudge chill the full 2 to 3 hours, rather than slicing early, gives the cleanest, most defined squares.

Troubleshooting Common Issues

My white chocolate is seizing up instead of melting smoothly. It was likely overheated; melt in shorter 10-second bursts and stir more frequently. My fudge has streaks of peanut butter instead of a uniform color. It wasn’t stirred quite long enough; keep stirring until no streaks remain and the mixture looks completely even. My fudge is too soft to slice even after chilling. Give it more time in the refrigerator; a full 3 hours, or even overnight, gives the cleanest slices. My fudge tastes grainy instead of smooth. The white chocolate was likely overheated at some point during melting; use shorter intervals and lower power next time.

A Few Ways to Make It Yours

The classic version is worth trying first so you know the baseline flavor before adding any extras.

How to Store This Fudge

Keep the fudge in an airtight container in the refrigerator for up to two weeks, since the white chocolate base holds its texture best when kept cool. Let it sit for a few minutes at room temperature before serving if you prefer a slightly softer bite.

When to Serve This Fudge

This fudge works beautifully for a holiday dessert tray, a bake sale, or any time a simple, crowd-pleasing peanut butter treat sounds appealing. It also makes a lovely addition to a homemade gift box alongside other no-bake treats.

Nutrition and Serving Information

This recipe makes about 16 squares at roughly 230 calories per serving, though exact calorie content will vary depending on the specific brands of white chocolate and peanut butter used. Because this recipe contains dairy and peanuts, it isn’t appropriate for anyone avoiding those ingredients.

Make-Ahead Tips

This fudge is a genuinely good make-ahead treat, since it holds its texture well in the refrigerator for up to two weeks after chilling. Making a batch several days before a gathering removes any last-minute pressure entirely.

The Science Behind This Fudge

White chocolate is made mostly of cocoa butter, milk solids, and sugar, which is why it melts smoothly at a lower temperature than milk or dark chocolate but also scorches more easily if overheated. Peanut butter, made largely of ground peanuts and their natural oils, blends into the melted white chocolate and firms back up as the fat in both ingredients re-solidifies during chilling, giving the finished fudge its dense, creamy structure.

Portioning and Yield

This recipe makes about 16 small squares from a single 8-inch pan, a good amount for a gathering or a gift tray. Doubling the ingredients and using a 9×13-inch pan works well for a larger batch, though it’s easiest to melt the white chocolate in two separate rounds so the stirring step stays manageable.

A Little Bit of History

Fudge made without a candy thermometer or cooked sugar stage, relying instead on melted chocolate that firms up as it chills, became a popular shortcut once microwaves made quick, even melting easy in home kitchens. Pairing white chocolate with peanut butter leans into a classic flavor combination that’s long been popular in candies and desserts, giving this simple fudge a familiar, comforting taste.

Serving Suggestions

Serve this fudge cut into small squares, arranged on a wood board with a jar of peanut butter and a bowl of white chocolate chips scattered around for a simple, rustic presentation. A light sprinkle of flaky sea salt over the platter adds a nice finishing touch if you want to dress it up further.

Choosing the Right Peanut Butter

A standard, shelf-stable creamy peanut butter works best here, since it stirs smoothly into the melted white chocolate and sets into a firm, even fudge once chilled. A natural, oil-separated peanut butter can work too, but stir it thoroughly before measuring, since the separated oil can otherwise throw off the texture of the finished fudge.

Why This Recipe Is So Beginner-Friendly

If you’ve never made fudge before, this is a genuinely forgiving place to start, since there’s no cooked sugar stage and no candy thermometer involved. With just two ingredients and a microwave, there’s very little room for the kind of mistakes that can derail a more involved candy recipe, which makes this a great project for a first-time cook.

Adjusting the Flavor to Your Taste

As written, this fudge gets its flavor almost entirely from the white chocolate base and the peanut butter stirred through it, giving a sweet, creamy, nutty taste. If you’d like a different flavor profile, swapping in a flavored peanut butter or adding a pinch of salt shifts the whole fudge in a new direction while keeping the same simple method. Because this recipe has so few ingredients to begin with, small changes tend to have a noticeable effect on the final flavor, so it’s worth trying the classic version first before deciding what, if anything, you’d like to change.

Pairing This Fudge With Other Treats and Drinks

Because the flavor here is sweet and creamy rather than rich or chocolatey, this fudge pairs naturally with darker, more chocolate-forward treats if you’re serving more than one dessert, since the contrast keeps a spread feeling balanced. A dark chocolate bark or a chocolate-dipped treat rounds out a dessert table nicely alongside this, while another peanut butter or white chocolate treat leans further into the same creamy direction. On the drink side, this fudge pairs well with coffee, cold milk, or hot chocolate.

A Note on Ingredient Proportions

Using 3 cups of white chocolate against ¾ cup of peanut butter keeps the fudge mostly creamy and mellow, with the peanut butter appearing as a rich, nutty backbone rather than overwhelming the base, and it’s worth understanding why that balance matters before adjusting it. Using too much peanut butter relative to the chocolate can keep the fudge from setting firmly, since the extra oil interferes with how the white chocolate solidifies. This particular ratio is what gives the finished fudge its classic smooth texture and balanced sweetness, so it’s worth treating the stated amounts as a tested baseline.

A Quick Note on Serving Temperature

This fudge tastes good straight from the refrigerator, which is also how it holds its shape best, since a warm square can soften enough for the white chocolate base to lose its structure. If serving at a warm gathering, keeping the platter in a cooler or shaded spot helps the fudge hold.

Why This Recipe Is Naturally Kid-Friendly to Make

Because this recipe involves melting chocolate and stirring in peanut butter with a spoon, it’s a genuinely fun treat to make with kids, with the microwave melting step handled by an adult. Pouring the mixture into the pan and smoothing the top is an especially easy, hands-on task that makes this a good weekend project.

A Quick Note on Portion Control

Because this fudge is rich with white chocolate and peanut butter, a small square goes a long way here compared to a lighter snack. Cutting the squares on the smaller side, as the yield suggests, is an easy way to stretch the batch further for a larger gathering.

A Note on Presentation

How you finish this fudge changes the impression it makes almost as much as the flavor itself. Cut plainly into squares, it reads as a simple homemade candy. Arranged on a wood board with a bar of white chocolate and a jar of peanut butter nearby, the same fudge suddenly looks like something from a specialty candy shop, which makes this a recipe worth dressing up for a gathering or keeping simple for an everyday treat.

A Final Note on Batch Size

This recipe is sized to make about 16 squares from a single 8-inch pan, which keeps the whole process manageable within about three hours including the chilling step. For a bigger batch to fill out a longer dessert table, double the ingredients and use a 9×13-inch pan rather than trying to overfill a single 8-inch pan, since a layer that’s too thick may need extra time in the refrigerator to set properly.

A Word on Texture

The texture of this fudge comes from how completely the peanut butter is stirred into the melted white chocolate, giving every square the same smooth, dense, melt-in-your-mouth bite rather than any streaks or pockets of either ingredient. That uniform texture is part of what makes this fudge feel polished, and it’s why stirring thoroughly, rather than just until barely combined, matters so much here.

A Note on Working With Melted White Chocolate

White chocolate behaves differently from milk or dark chocolate when melted, since it contains no cocoa solids and scorches more easily under too much heat. Melting it in short intervals and stirring thoroughly between each is the simplest way to avoid a grainy, seized mixture that won’t blend smoothly with the peanut butter. Using a completely dry bowl and dry utensils also matters more than usual here, since even a single drop of water can cause white chocolate to seize into a thick, unworkable mass.

A Note on Gifting This Batch

Because it holds its shape well once chilled, this fudge travels nicely as a homemade gift, provided it’s kept reasonably cool along the way. Layered into a small tin with parchment between layers, a dozen or so squares makes a simple, pretty gift for a peanut butter fan, and the pale, creamy color looks lovely without any extra decorating needed.

A Note on Scaling Down the Batch

If a full batch of 16 squares is more than you need, this recipe halves easily, since the ratio between white chocolate and peanut butter stays simple to work out either way. A smaller batch is a good option for a quick craving or a single gift box without committing to a full pan, and it still only takes the same handful of minutes to melt, combine, pour, and chill before the fudge is ready to slice.

A Note on Choosing Your Pan

An 8-inch square pan is the size this recipe is written for, and it gives squares with a satisfying thickness once the fudge is sliced. A slightly larger pan works too, but keep in mind the layer will be thinner, which means the squares will set a little faster in the fridge and should be checked a bit earlier than the full 2 to 3 hours. Metal and glass pans both work well here; glass lets you see the layer thickness as you spread the fudge, which can be helpful the first time you make this. Whatever pan is used, the parchment lining matters more than the material, since it’s what allows the finished fudge to lift out cleanly in one solid piece rather than needing to be scraped out in pieces.

Why Parchment Paper Makes a Difference

It’s worth taking the extra minute to line the pan properly, letting the parchment hang over two opposite edges so there’s something to grip when it’s time to lift the set fudge out. Pressing the parchment into the corners before pouring the fudge mixture helps it hold its shape rather than sliding around, and smoothing out any major wrinkles keeps the bottom of the fudge from picking up a textured pattern. This small step saves a lot of frustration later, since fudge that’s stuck to a bare pan is much harder to remove in neat squares, and a few jagged edges can throw off how evenly sized the finished pieces turn out to be.

Common Questions

However you dress it up and whoever you share it with, this creamy white chocolate peanut butter fudge delivers smooth, rich sweetness from nothing more than two simple ingredients. It’s proof that a quick no-bake treat can taste just as polished as it looks.
