Ingredients
The ingredient list for Peanut Butter Fudge Bars is short, sweet, and readily accessible, highlighting the simplicity of this delightful treat. Each component is essential for achieving the perfect flavor and texture balance. Here’s what you’ll need to gather:
- 1 cup (2 sticks) Unsalted Butter, Cut into Cubes: Butter forms the rich base of the peanut butter fudge layer, providing creaminess, flavor, and structure. Unsalted butter is preferred to control the overall salt level in the fudge. Cutting the butter into cubes ensures it melts evenly and quickly. For a vegan option, you can use a good quality vegan butter stick, ensuring it is unsalted.
- 3 cups Powdered Sugar, Sifted: Powdered sugar provides sweetness and helps to create the smooth, fudge-like texture of the peanut butter layer. Sifting the powdered sugar is important to remove any lumps, ensuring a perfectly smooth fudge base.
- 1 ½ cups Creamy Peanut Butter: Peanut butter is, of course, the star of the show! Creamy peanut butter is recommended for the smoothest fudge texture. Choose a good quality peanut butter that is smooth and creamy, without added sugar or stabilizers if possible, for the purest peanut butter flavor. You can use regular or natural creamy peanut butter, but natural peanut butter may result in a slightly softer fudge due to its higher oil content.
- 1 teaspoon Vanilla Extract: Vanilla extract enhances the overall flavor of the fudge, adding a touch of warmth and complexity that complements both the peanut butter and chocolate. Use pure vanilla extract for the best flavor.
- Pinch of Salt (Optional but Recommended): A pinch of salt, especially if using unsalted peanut butter, helps to balance the sweetness and enhance the peanut butter and chocolate flavors, creating a more well-rounded taste.
- For the Chocolate Ganache Topping:
- 1 cup Semi-Sweet Chocolate Chips or Chopped Semi-Sweet Chocolate: Semi-sweet chocolate provides a classic chocolate flavor that pairs perfectly with peanut butter. You can use semi-sweet chocolate chips for convenience or chop a semi-sweet chocolate bar for a richer chocolate experience. You can also experiment with dark chocolate chips or chopped dark chocolate for a less sweet and more intense chocolate ganache.
- ½ cup Heavy Cream or Coconut Cream (for Vegan Option): Heavy cream creates the smooth, glossy, and pourable chocolate ganache topping.
- Heavy Cream (Traditional): Heavy cream is the traditional choice for a rich and decadent ganache. It provides the perfect fat content for a smooth and pourable consistency.
- Coconut Cream (Vegan Option): For a vegan version, full-fat coconut cream (the thick, solid part from a refrigerated can of full-fat coconut milk) is an excellent substitute for heavy cream. It creates a rich and creamy vegan ganache. Ensure you use the solid cream part and not the watery liquid in the can.
Instructions
Making Peanut Butter Fudge Bars is a wonderfully straightforward and no-bake process. Follow these step-by-step instructions to create your own batch of irresistible fudge bars:
- Prepare the Pan: Line an 8×8 inch square baking pan with parchment paper. Leave an overhang of parchment on the sides to easily lift the fudge bars out later. Ensure the parchment fits snugly into the corners for a neat finish. Lightly grease the parchment paper with butter or cooking spray to prevent sticking and ensure easy removal of the fudge bars.
- Melt Butter in a Saucepan: In a medium-sized saucepan, melt the cubed unsalted butter over medium-low heat. Melt the butter completely, but do not let it brown or boil. Remove the saucepan from the heat once the butter is fully melted.
- Stir in Powdered Sugar: To the melted butter in the saucepan, add the sifted powdered sugar. Stir well with a spatula or wooden spoon until the powdered sugar is fully incorporated into the melted butter and the mixture is smooth and combined. Ensure there are no lumps of powdered sugar remaining.
- Add Peanut Butter, Vanilla, and Salt: Add the creamy peanut butter, vanilla extract, and pinch of salt (if using) to the butter and powdered sugar mixture in the saucepan.
- Stir Until Smooth Fudge Forms: Stir continuously and vigorously with a spatula or wooden spoon until all the ingredients are thoroughly combined and a smooth, creamy peanut butter fudge mixture forms. Continue stirring until the mixture is homogenous and no streaks of butter or powdered sugar remain. The mixture will thicken as you stir.
- Press Fudge into Prepared Pan: Pour the peanut butter fudge mixture into the parchment-lined baking pan.
- Spread Evenly and Firmly: Use a spatula or the back of a spoon to spread the fudge evenly in the pan, pressing it down firmly to create a smooth and compact layer. Ensure the fudge reaches all corners of the pan and has a level top surface.
- Prepare the Chocolate Ganache Topping: While the fudge layer sets, prepare the chocolate ganache topping.
- Combine Chocolate and Heavy Cream/Coconut Cream: In a microwave-safe bowl or a heatproof bowl set over a saucepan of simmering water (double boiler method), combine the semi-sweet chocolate chips (or chopped chocolate) and heavy cream (or coconut cream).
- Melt Ganache: Microwave in 30-second intervals at 50% power, stirring well after each interval, until the chocolate is mostly melted and the cream is heated through. Alternatively, if using the double boiler method, heat over simmering water, stirring constantly, until the chocolate is melted and smooth.
- Stir Until Smooth and Glossy: Continue to stir the chocolate and cream mixture until it is completely smooth, glossy, and homogenous. Ensure there are no streaks of chocolate or cream remaining and the ganache is perfectly combined.
- Pour Ganache Over Fudge Layer: Pour the prepared chocolate ganache evenly over the set peanut butter fudge layer in the baking pan.
- Spread Ganache Smoothly: Use a spatula or the back of a spoon to spread the chocolate ganache evenly over the fudge layer, creating a smooth and uniform chocolate topping.
- Chill to Set Completely: Chill the Peanut Butter Fudge Bars in the refrigerator to allow both the fudge layer and the chocolate ganache topping to set completely and become firm.
- Refrigerate: Refrigerate the pan in the refrigerator for at least 2-3 hours, or preferably overnight, to allow the fudge bars to set firmly and become easy to cut. Overnight chilling is recommended for the best texture and ease of cutting.
- Cut and Serve: Once the fudge bars are fully chilled and firm, remove them from the pan.
- Lift from Pan: Lift the fudge bars out of the pan using the parchment paper overhang.
- Cut into Bars or Squares: Place the fudge block on a cutting board. Use a sharp knife to cut the fudge bars into squares, rectangles, or desired shapes. For clean cuts, you can dip the knife in hot water and wipe it dry between each cut.
- Enjoy! Arrange the Peanut Butter Fudge Bars on a serving platter and enjoy this creamy, chocolatey, and utterly decadent treat!

Additional Tips for Perfect Peanut Butter Fudge Bars
To ensure your Peanut Butter Fudge Bars are consistently creamy, chocolatey, and utterly irresistible, keep these five essential tips in mind:
- Sift Powdered Sugar for Smooth Fudge: Sifting the powdered sugar before adding it to the melted butter is crucial for achieving a perfectly smooth, lump-free peanut butter fudge layer. Sifting removes any clumps and ensures even incorporation, resulting in a velvety texture.
- Use Creamy Peanut Butter (Not Natural, Unless Stirred Well): While natural peanut butter can be used, regular creamy peanut butter is recommended for the best texture in this recipe. If using natural peanut butter, make sure it is well-stirred and homogenous, as the oil separation can affect the fudge consistency.
- Don’t Overheat the Ganache: When making the chocolate ganache topping, melt the chocolate and cream gently and slowly, whether using a microwave or double boiler. Avoid overheating the ganache, as it can become grainy or separate. Heat in short intervals and stir frequently until just melted and smooth.
- Chill Completely Before Cutting: Chilling the fudge bars thoroughly in the refrigerator for at least 2-3 hours (or overnight) is essential for them to set firmly and become easy to cut into clean bars. Rushing the chilling process can result in soft, sticky fudge that is difficult to cut neatly.
- Warm Knife for Clean Cuts: For neat, professional-looking cuts, dip a sharp knife in hot water, wipe it dry, and then cut the fudge bars. Repeat this process between each cut, dipping and wiping the knife to ensure clean slices without dragging or crumbling the fudge.
Frequently Asked Questions (FAQs)
Here are answers to some common questions about making Peanut Butter Fudge Bars to help you troubleshoot and achieve fudge bar perfection:
Q1: My fudge bars are too soft and didn’t set properly. What did I do wrong?
A: If your fudge bars are too soft and didn’t set, the most likely reason is that they weren’t chilled for long enough. Ensure you chill them in the refrigerator for at least 2-3 hours, or preferably overnight. If they are still too soft after adequate chilling, it could also be due to using too much butter or not enough powdered sugar in the fudge layer. Double-check your ingredient measurements for accuracy.
Q2: Can I use chunky peanut butter instead of creamy peanut butter?
A: While creamy peanut butter is recommended for the smoothest fudge texture, you can use chunky peanut butter if you prefer a fudge with more texture and peanut pieces. Chunky peanut butter will add bits of peanuts throughout the fudge, altering the texture but still providing delicious peanut butter flavor.
Q3: Can I make these fudge bars vegan?
A: Yes, Peanut Butter Fudge Bars can easily be made vegan by making a few simple substitutions:
- Vegan Butter: Use a good quality vegan butter stick instead of dairy butter for the fudge layer.
- Coconut Cream Ganache: Use full-fat coconut cream (the thick, solid part from refrigerated canned coconut milk) instead of heavy cream for the chocolate ganache topping.
Q4: How long do Peanut Butter Fudge Bars last?
A: Peanut Butter Fudge Bars will last for up to 1 week when stored in an airtight container in the refrigerator. For longer storage, you can freeze them in an airtight container for up to 2-3 months. Thaw them in the refrigerator overnight before serving. Freezing may slightly alter the texture, making them a bit firmer when thawed, but they will still be delicious.
Q5: Can I add toppings to the chocolate ganache?
A: Absolutely! You can customize your Peanut Butter Fudge Bars with various toppings added to the chocolate ganache before it sets. Some popular topping ideas include:
- Chopped Peanuts: Sprinkle chopped peanuts over the ganache for extra peanut crunch and flavor.
- Sea Salt Flakes: Sprinkle flaky sea salt for a salty-sweet contrast.
- Mini Chocolate Chips: Add mini chocolate chips for extra chocolatey goodness.
- Sprinkles: Use colorful sprinkles for a festive touch, especially for holidays or parties.
- Pretzel Pieces: Broken pretzel pieces for a salty and crunchy topping.
