Pro Tips for the Best Peanut Butter Fudge
- Use creamy peanut butter for a smooth texture, but chunky peanut butter works if you love extra crunch.
- Don’t overheat the peanut butter mixture—just warm enough to stir smoothly.
- Line your dish with parchment paper for easy removal and clean slices.
- Let it chill fully for the best consistency; rushing may cause it to be too soft.

Frequently Asked Questions (FAQs)
❓ Can I use natural peanut butter?
Yes, but stir it well before use. Natural peanut butter can make the fudge softer due to the oil separation.
❓ Do I need to use powdered sugar?
Yes, powdered sugar is essential for structure and smooth texture. Granulated sugar won’t dissolve properly.
❓ Can I make this without a microwave?
Absolutely! Melt the peanut butter and condensed milk in a saucepan over low heat, stirring constantly.
❓ Can I double the recipe?
Yes! Just use a larger dish and add a few extra minutes to the chilling time.
