What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Everything you need is probably already in your pantry, which makes this fudge a lifesaver when time’s tight.

• Peanut Butter (creamy or chunky, about 1 cup / 250g): The star of the show. I usually go for a natural peanut butter with no added sugar for a pure nutty flavor, but creamy works best for that smooth texture.
• Powdered Sugar (2 cups / 240g): This sweetens and thickens the fudge. Make sure to sift it if it’s clumpy—smoothness is key.
• Unsalted Butter (1/2 cup / 115g, softened): Adds richness and helps the fudge set with a melt-in-your-mouth feel. I prefer European-style butter for that extra creaminess.
• Vanilla Extract (1 teaspoon / 5ml): Just a touch to round out the flavors and add warmth.
• Salt (a pinch): Enhances the peanut butter’s natural flavor and balances the sweetness.

If you want a twist, you can swap out the peanut butter for almond or cashew butter, but keep in mind the texture might shift slightly. For a dairy-free version, substitute the butter with coconut oil (use firm, refrigerated coconut oil for best results). Also, if you’re in the mood for a little crunch, stir in chopped peanuts or even a handful of mini chocolate chips before setting.

Equipment Needed

Luckily, this recipe calls for only the basics—no fancy gadgets required.

• Mixing Bowl: A medium to large bowl to combine your ingredients comfortably. Glass or metal works fine.
• Hand Mixer or Wooden Spoon: For mixing the butter and peanut butter into a creamy blend. I usually use a hand mixer for smoothness, but a sturdy spoon works if you want a bit more arm workout.
• Measuring Cups and Spoons: Accurate measurements make a big difference in fudge texture.
• 8×8-inch Baking Pan: For setting the fudge evenly. Line it with parchment paper for easy removal.
• Spatula: To spread the fudge evenly in the pan and scrape every bit from the bowl.

If you don’t have a hand mixer, no worries—just mix a bit longer to get that creamy base. The parchment lining is a game-changer for cleanup and lifting the fudge out in perfect squares. I’ve tried silicone molds too, but the pan method gives the best even thickness.

Preparation Method

1. Prepare the Pan: Line your 8×8-inch (20×20 cm) baking pan with parchment paper, leaving some overhang on the sides. This will help lift the fudge out easily once set. Set aside.
2. Mix the Butter and Peanut Butter: In a medium bowl, combine 1/2 cup (115g) softened unsalted butter and 1 cup (250g) peanut butter. Use a hand mixer on medium speed or a sturdy wooden spoon to blend until smooth and creamy, about 2-3 minutes. The mixture should look glossy and uniform.
3. Add Vanilla and Salt: Stir in 1 teaspoon (5ml) vanilla extract and a pinch of salt. These little touches bring depth to the fudge, so don’t skip them.
4. Incorporate Powdered Sugar: Gradually sift in 2 cups (240g) powdered sugar, folding gently with a spatula after each addition. When it gets too thick to stir, switch to kneading with your hands (clean, of course) to combine fully. The dough should be firm but pliable, not crumbly.
5. Transfer and Flatten: Scrape the fudge mixture into the prepared pan. Use a spatula or the back of a spoon to press it evenly and smooth the surface. This is where you can press in optional add-ins like chopped peanuts or mini chocolate chips if you want a little surprise in every bite.
6. Chill: Place the pan in the refrigerator for at least 2 hours, or until the fudge is firm to the touch. I like to cover it loosely with plastic wrap to avoid fridge odors.
7. Cut and Serve: Once firm, lift the fudge out using the parchment overhang. Cut into 1-inch (2.5 cm) squares with a sharp knife. For cleaner cuts, warm your knife under hot water and wipe dry before slicing.

Pro tip: If your fudge feels too soft after chilling, pop it back in the fridge for another hour. Too dry? A quick whisk with a teaspoon of cream or milk can rescue the texture before setting again. Also, don’t rush the chilling step; the fudge needs time to set properly to get that perfect bite.

Cooking Tips & Techniques

Making fudge may seem simple, but getting the texture just right takes a few tricks I’ve learned the hard way.

• Softened Butter is a Must: If your butter is too cold, it won’t blend smoothly, leaving lumps and a gritty texture. Room temperature but still cool butter is ideal.
• Sift Powdered Sugar: This avoids clumps and makes folding in easier. Nothing ruins fudge texture like gritty sugar pockets.
• Don’t Overmix: Once the sugar is fully incorporated, stop mixing. Overworking the mixture can make the fudge tough.
• Use a Warm Knife for Cutting: It prevents crumbling and uneven edges, giving you pretty squares every time.
• Chill, Don’t Freeze: Freezing can make the fudge brittle and dry. Slow chilling in the fridge is the way to go.
• Patience Pays Off: Let the fudge set fully before cutting. I’ve ruined batches by slicing too soon—waiting is worth it.

One time, I skipped sifting the sugar and ended up with unpleasant lumps that totally ruined the silky feel. Since then, I never skip that step. Also, I’ve found that using natural peanut butter with no added oil gives a denser, more satisfying fudge, but creamy commercial brands work if you’re in a pinch.

Variations & Adaptations

This easy 5-ingredient peanut butter fudge is a great base for personalization. Here are some ways I’ve made it my own (and you can too):

• Chocolate Swirl: Melt 1/4 cup (60g) semi-sweet chocolate chips and swirl into the fudge before chilling for a marbled effect.
• Nut-Free Version: Use sunflower seed butter instead of peanut butter to make it allergy-friendly while keeping the creamy texture.
• Crunch Factor: Stir in 1/2 cup (50g) chopped roasted peanuts or crushed pretzels for a salty crunch contrast.
• Flavor Boost: Add a pinch of cinnamon or a dash of espresso powder to deepen the flavor profile.
• Dairy-Free: Swap butter with firm coconut oil and use powdered coconut sugar to keep it vegan.

I once tried folding in tiny bits of the crispy caraway twists for a savory-sweet surprise, and it was unexpectedly addictive. Feel free to experiment with your favorite add-ins or spices. Just keep the base ratio intact for best results.

Serving & Storage Suggestions

This fudge is best served chilled or at cool room temperature. The texture softens slightly as it warms but still holds its shape beautifully. I like arranging the squares on a simple white plate to showcase the glossy peanut butter surface—sometimes with a sprinkle of flaky sea salt on top for a little contrast.

It pairs delightfully with tea or coffee, and if you’re hosting a party, it makes a sweet finish alongside savory bites like the mini cheese balls or the zesty garlic marinated mushrooms. The creamy fudge balances those bold flavors perfectly.

For storage, keep the fudge in an airtight container in the refrigerator for up to 2 weeks. You can also freeze it for up to 3 months—just thaw in the fridge overnight before serving. When reheating leftovers, let them come to room temperature for a few minutes to regain that soft, melt-in-your-mouth texture.

Interestingly, the fudge’s flavor deepens and the texture firms up slightly after a day or two in the fridge, making it even more addictive. So, if you can wait, I promise the patience pays off.
