How about whipping up this simple peanut butter fudge to indulge your sweet tooth? It’s a quick dessert that can be made in the microwave rather than on the stovetop. Then chill, slice, and enjoy!
Make Peanut Butter Fudge in the Microwave
This vintage recipe is modernized for busy schedules and a microwave oven! It is easy to make when you have limited time. However, it can also be made in a heavy saucepan on the stovetop using low to medium heat by melting the peanut butter chips and marshmallows with condensed milk. Then, remove it from the heat and add the remaining ingredients. Either method is quick and easy!

Substitute Butterscotch for Peanut Butter Chips
My mother got this recipe from a friend years ago. It was a new twist on chocolate fudge and was a big hit among nonchocolate eaters and fudge lovers. The original recipe used butterscotch instead of peanut butter chips, which gives the fudge a slight taste difference. However, you can use either flavor of chips in this recipe. If you make butterscotch fudge rather than peanut butter, use high-quality butterscotch chips for the best flavor.

Peanut Butter Fudge Steps
Add the ingredients to a large microwavable container. I like to use a glass measuring cup with a handle to make it easy to insert and remove from the microwave oven. Cook the ingredients for 30-second intervals, stirring between each interval. It will take about 3 minutes total time to fully melt the mixture.
Although it is tempting to heat the ingredients for three full minutes before stirring, this should be avoided. Prolonged heating can cause the mixture to overcook. Stirring well between intervals helps distribute heat and melt the peanut butter chips and marshmallows evenly.









Peanut Butter Fudge Storage
Keep the fudge in the refrigerator and cover it tightly to prevent it from drying out. It will keep its fresh flavor for about a week. You can also freeze it in an airtight container to make it ahead of when you want to serve it.
