Helpful Tips
Use Regular Creamy Peanut Butter
Go with a standard creamy peanut butter like Jif or Skippy for this recipe. These have stabilizers in them that help the fudge set up firm and hold its shape when you cut it into squares.
Natural peanut butter (the kind where the oil separates to the top) has a different texture and consistency. It makes the fudge greasy and soft, and it won’t firm up the way it should in the fridge.
If all you have is natural peanut butter, you can still try it, but just know the fudge will be softer and harder to cut into clean squares.
Microwave the Peanut Butter and Butter in Short Bursts
Instead of running the microwave for the full 1-2 minutes straight, heat it in 30 second bursts and stir in between each one. This way the butter melts evenly and nothing gets overheated or starts to bubble.
Overheated peanut butter gets oily and can separate, which messes with the texture of your fudge. You just want the butter fully melted and the peanut butter warm enough to stir smooth.
Once you can stir them together into one smooth mixture with no chunks of butter left, you’re good to move on.
Sift Your Powdered Sugar
Powdered sugar loves to clump up in the bag, and those little lumps don’t always break down when you stir them in. If you skip sifting, you can end up with white pockets of dry sugar in your finished fudge.
Just run it through a fine mesh strainer or a sifter into a bowl before you add it to the peanut butter mixture. It takes about one extra minute and makes a big difference in how smooth your fudge turns out.

Frequently Asked Questions
Can I use crunchy peanut butter instead of creamy?
You can, and it will give your fudge a nice nutty texture with little peanut pieces throughout. Just keep in mind that the fudge won’t be as smooth and it might be slightly harder to press evenly into the pan.
If you like a bit of crunch in your fudge, go for it. The recipe works the same way either way.
