Notes

 
Use creamy peanut butter for the smoothest fudge.
Keep the heat low when melting the peanut butter and butter.
Do not add too much milk, as this can make the fudge too soft.
For peanut butter fudge with fluff, stir marshmallow fluff into the warm peanut butter mixture before adding the powdered sugar.
For peanut butter fudge with condensed milk, replace part of the powdered sugar mixture with sweetened condensed milk and adjust the consistency as needed.
For a simple 2 ingredient fudge condensed milk variation, combine sweetened condensed milk with chocolate chips, then add peanut butter for extra flavor.
Store in an airtight container in the refrigerator for up to 1–2 weeks.
Freeze for longer storage and thaw in the refrigerator before serving.
