Tips & Tricks
- Stir well between microwave intervals to ensure even melting and prevent hot spots
- Add the powdered sugar gradually โ this prevents lumps and makes mixing easier
- Press the fudge firmly into the pan for clean, even squares when you cut it
- Let the parchment paper hang over the edges of the pan so you can easily lift the whole block out for cutting
- Press the mini chocolate chips gently into the top so they stick when you cut the fudge
- Let the fudge sit at room temperature for about 10 minutes before cutting for cleaner slices

Recipe FAQs
Can I use natural peanut butter? Regular creamy peanut butter works best for this recipe. Natural peanut butter with oil separation can make the texture grainy and wonโt set up as well.
Why is my fudge crumbly? If your fudge is crumbly, it likely needed a bit more butter or the peanut butter mixture got too cool before mixing in the powdered sugar. Make sure everything is well combined while still warm.
Can I make this without chocolate chips? Absolutely! The chocolate chips are optional and just add decoration and extra flavor. Plain peanut butter fudge is delicious on its own.
How do I get clean cuts when slicing? Use a sharp knife and wipe it clean between cuts. You can also run the knife under hot water, dry it, then cut for even cleaner edges.
Can I double this recipe? Yes! Use a 9ร13-inch pan instead of an 8ร8-inch pan. The microwave time and chill time stay the same, youโll just have more pieces of fudge.
Why do I need to chill it for so long? The two-hour chill time allows the fudge to firm up completely so it holds its shape when cut. You can speed this up slightly by putting it in the freezer for about an hour instead.
