Step-by-Step Instructions
Step 1: Prep the Pan
Line an 8×8-inch baking dish with parchment paper, leaving overhangs for easy removal. Lightly grease the paper to prevent sticking.

Step 2: Melt the Butter
In a microwave-safe bowl, melt the butter in 15-second intervals until fully liquid. Stir in the peanut butter until smooth and glossy.

Step 3: Add Powdered Sugar
Gradually sift in the powdered sugar, mixing until fully incorporated. For a fluffier texture, use a hand mixer (low speed).
Step 4: Transfer and Chill
Spread the mixture evenly into the prepared pan. Refrigerate for 1–2 hours until firm. Slice into squares and serve! For more bite-sized treats, try our homemade pop tarts.

Common Mistakes to Avoid
Making peanut butter fudge seems simple, but even small errors can ruin its creamy texture. Here are common pitfalls to avoid:
1. Overheating the Mixture
Overheating can make your fudge grainy or too hard. Use low heat and stir constantly to prevent burning. A candy thermometer helps—aim for 235°F (soft-ball stage).
2. Skipping the Sifting Step
Powdered sugar often clumps. Sift it before mixing to ensure a smooth, lump-free peanut butter fudge.
3. Using Low-Quality Peanut Butter
Opt for creamy, natural peanut butter without added oils. Avoid crunchy varieties—they disrupt the fudge’s velvety consistency.
4. Rushing the Cooling Process
Let the fudge set at room temperature for 2+ hours. Refrigerating too soon causes uneven texture or cracking.
5. Overmixing
Stir just until combined. Overmixing incorporates excess air, making the fudge crumbly instead of dense and rich.

Storing Tips for the Recipe
Proper storage keeps your peanut butter fudge fresh and delicious. Follow these tips:
1. Airtight Containers
Store fudge in an airtight container at room temperature for up to 2 weeks. Layer parchment paper between pieces to prevent sticking.
2. Refrigeration
For longer shelf life (3–4 weeks), refrigerate. Bring to room temperature before serving to restore creaminess.
3. Freezing
Freeze for up to 3 months! Wrap individual pieces in wax paper, then place in a freezer bag. Thaw overnight in the fridge.
4. Avoid Humidity
Moisture makes fudge sticky. Store in a cool, dry place—away from stoves or sinks.

FAQs
1. Can I use natural peanut butter for this fudge?
Yes, but ensure it’s well-stirred and creamy. Natural peanut butter may alter the texture slightly due to its oil content.
2. How long does homemade peanut butter fudge last?
Stored properly in an airtight container, it stays fresh for up to 2 weeks at room temperature or 3 months in the freezer.
3. Can I substitute powdered sugar with another sweetener?
Powdered sugar works best for smoothness, but you can try coconut sugar (blended finely) or maple syrup (adjusting consistency).
4. Why is my fudge too soft?
This usually happens if the butter wasn’t fully incorporated or the mixture wasn’t chilled long enough. Pop it back in the fridge for an extra hour.
