Ingredients You’ll Need
Part of what makes the Easiest Peanut Butter Fudge so lovable is its short, sweet ingredient list. Each one plays a starring role in creating that perfectly creamy texture and unmistakable flavor this fudge is known for. Here’s what you’ll need (plus little tips to make the most of each!):
- Creamy Peanut Butter: Delivers that signature flavor and luscious, silky texture; use a high-quality brand for the richest taste.
- Unsalted Butter: Adds unbelievable creaminess while balancing the sweetness; make sure it’s unsalted so you can control the flavor.
- Vanilla Extract: Rounds out the flavors and brings a warm, delightful aroma—real vanilla makes a difference here!
- Powdered Sugar: Sweetens and gives structure to the fudge; sift it if you’re worried about lumps for ultra-smooth results.
How to Make Easiest Peanut Butter Fudge
Step 1: Prepare Your Baking Dish
Line an 8×8-inch baking dish with parchment paper, making sure the paper hangs over the edges for easy lifting later. This not only prevents sticking but also guarantees perfect squares when you’re ready to slice. If you want to keep cleanup simple, this step is not negotiable!
Step 2: Melt Peanut Butter and Butter
In a large microwave-safe bowl, combine your creamy peanut butter and unsalted butter. Microwave in 30-second bursts, stirring after each interval, until the mixture is fully melted and silky smooth. Usually, this will take about 1-2 minutes total. Keep a close eye so nothing scorches—gentle and gradual is key!
Step 3: Add Vanilla Extract
Once the peanut butter and butter mixture is melted and blended, stir in the vanilla extract. This simple addition makes everything taste just a little more special, infusing the fudge with warmth and depth.
Step 4: Mix in Powdered Sugar
Working a little at a time, blend the powdered sugar into your warm mixture. You’ll notice the fudge thickens quickly—just keep stirring patiently until it’s smooth and no streaks or lumps of sugar remain. If necessary, use the back of a spoon to press out any pesky sugar clumps.
Step 5: Spread and Smooth
Transfer the fudge mixture into your prepared pan. Using a spatula, spread it out evenly, then smooth the top for a flawless finish. If you love a sweet-and-salty combo, this is the moment to sprinkle a little flaky sea salt on top for an irresistible touch.
Step 6: Chill and Slice
Pop the fudge in your refrigerator and let it set for at least 2 hours. Once firm, grab the edges of the parchment paper and lift the whole slab out, then cut into small, crave-worthy squares. That’s it—your Easiest Peanut Butter Fudge is ready to wow!
How to Serve Easiest Peanut Butter Fudge
Garnishes
A little flourish goes a long way! Try a sprinkle of flaky sea salt to enhance the peanut butter, or finely chopped roasted peanuts for extra crunch. For a festive vibe, consider dusting with cocoa powder, drizzling with melted chocolate, or adding colorful sprinkles. A light dusting makes each bite feel extra thoughtful.
Side Dishes
Since Easiest Peanut Butter Fudge is rich and satisfying, it pairs beautifully with simple sips like hot coffee or cold milk. For parties, serve alongside fresh berries or a tangy fruit salad to brighten up the dessert spread, or layer it with vanilla ice cream for over-the-top sundaes.
Creative Ways to Present
Presenting fudge can be half the fun! Stack squares high on a tiered serving platter for eye-catching height, or box them in cute paper liners for homemade gifts. You can even cut the fudge into fun shapes with small cookie cutters or serve skewered on sticks for an unexpected treat at parties.
Make Ahead and Storage
Storing Leftovers
Keep any uneaten Easiest Peanut Butter Fudge in an airtight container in the refrigerator, where it will stay fresh and creamy for up to a week. Make sure each layer is separated with parchment paper to avoid sticky situations and help preserve those neat edges.
Freezing
If you’d like to save some for later (or stow away a secret stash!), this fudge freezes wonderfully. Wrap the squares tightly in plastic wrap, then place in a zip-top bag or airtight container. They’ll keep for up to three months—just thaw in the fridge overnight when ready to indulge.
Reheating
While fudge isn’t typically reheated, if you prefer it a bit softer, let the squares sit at room temperature for 10-15 minutes before serving. This will bring back that silky texture without any actual reheating or melting.
FAQs
Can I use natural peanut butter for this fudge?
You can, but the results may vary. Natural peanut butter often separates and isn’t as creamy as conventional brands, which can lead to a grainier, oilier fudge. For the creamiest result that stays true to the Easiest Peanut Butter Fudge, stick with classic creamy peanut butter.
Is it possible to make this recipe vegan?
Absolutely! Simply swap in a good-quality plant-based butter for the dairy version. Make sure your powdered sugar is vegan (some brands use bone char in processing). The end result is just as dreamy, so everyone can enjoy a square.
Can I double the recipe for a larger crowd?
Definitely! Just double each ingredient and use a 9×13-inch pan for setting. The Easiest Peanut Butter Fudge scales up perfectly and is a lifesaver when you need to feed a lot of sweet tooths in a hurry.
Why is my fudge crumbly or dry?
This usually happens if too much powdered sugar is added, or if the fudge is mixed while too hot. Measure carefully and allow the mixture to cool slightly before stirring in the sugar for the best, creamiest fudge consistency.
Can I add mix-ins like chocolate chips or nuts?
Of course! For a fun twist on the Easiest Peanut Butter Fudge, gently fold in a handful of mini chocolate chips, chopped walnuts, or even swirls of caramel before spreading the mixture in the pan. Just be sure not to overload the fudge so it keeps its classic texture.
