Can I use powdered sugar instead of sweetened condensed milk?

Oh honey, no. (And trust me, I learned this the hard way.) Powdered sugar fudge is a totally different beast—it’ll turn out crumbly and overly sweet. The magic here is in the thick, velvety sweetened condensed milk. It acts like glue, giving that melt-in-your-mouth texture we all crave. That said, if you’re feeling adventurous, check out sous-vide precision cooker techniques for sugar-based fudge—just know it’s a whole different project!

Is natural peanut butter okay to use?

Absolutely! Just know it’ll be less sweet and might have a slightly grainier texture since it lacks those added stabilizers. If you go this route, I’d suggest stirring the jar really well first—natural PB loves to separate, and nobody wants oily fudge surprises!

How long does peanut butter fudge last?

In the fridge? A solid week—if it lasts that long! Just keep it wrapped tight. Fun fact: I once forgot a batch in the back of my fridge for two weeks (don’t judge), and it was still delicious. For longer storage, freeze it—those squares thaw perfectly for sudden sweet cravings.
