    🥜An easy fudge recipe

    This creamy peanut butter fudge recipe is an easy recipe that doesn't require a candy thermometer, like this one! It is an old fashioned fudge recipe so it doesn't have marshmallow fluff or sweetened condensed milk in it. It requires only a handful of ingredients.

    This fudge has tons of peanut butter flavour which pairs so well with the sweetness of the sugar. I used smooth peanut butter for this recipe, but you can easily substitute with crunchy peanut butter.

    🥘Ingredients

    All the ingredients needed to make fudge.

    📝Ingredient notes

    • Light brown sugar - you can substitute with dark brown sugar. Your fudge will just be a lot darker in colour.
    • Peanut butter - substitute creamy peanut butter for chunky, if you prefer.

    🔪Instructions

    Instruction number 1 for making creamy peanut butter fudge.

    Grease a 9x9 or 8x8 inch baking pan, and line with parchment paper. Melt butter in a small saucepan over medium heat. Stir in brown sugar and milk when melted. Bring everything to a boil and stir constantly for 2 minutes.

    Remove the saucepan from the heat and stir in peanut butter and vanilla extract. Stir in icing sugar until smooth.

    Instruction number 2 for making creamy peanut butter fudge.

    Spread the fudge into the prepared baking dish. Let it cool at room temperature and then store it in the refrigerator in an airtight container for up to 2 weeks.

    ✔️Expert Tips

    • Substitute creamy peanut butter for chunky if you want.
    • Have all your ingredients ready before you start. Things move quickly once you begin making fudge.
    • Make sure you cook the fudge on the stovetop for as long as the recipe says. It will not set otherwise.

    💭Recipe FAQ's

    How do I store fudge?

    Store it in an airtight container in the refrigerator for up to 2 weeks.

    Can I freeze fudge?

    Wrap the fudge in plastic wrap and then put it inside a freezer bag or container. It can freeze for up to 2 months. Thaw by leaving it in the refrigerator for 3-4 hours.

    How do I cut fudge neatly?

    Cut the fudge when it has slightly firmed up, about an hour into it's cooling time.

    What causes peanut butter fudge to not harden?

    The fudge mixture did not get hot enough, or was not cooked long enough.

      I was going to try this till I saw the content of sugar. Wow! The old fashioned doesn’t use powdered sugar. Maybe it’s is no boil? Will look at recipe further. Thanks for sharing.

        Hi Karen! There's brown sugar in it, and the brown sugar and butter gets boiled. You add the powdered sugar when it comes off the heat. I hope you try it! It's easier than most old fashioned fudge 🙂
