Ingredients For Peanut Butter Fudge Recipe
Sugar: Provides the sweetness and structure for the fudge.
Milk: Adds creaminess and helps dissolve the sugar.
Peanut butter: The star ingredient, giving the fudge its rich, nutty flavor.
Vanilla extract: Enhances the overall flavor with a hint of vanilla.
Technique Tip for This Recipe
To achieve a smoother texture in your peanut butter fudge, make sure to use a candy thermometer when boiling the sugar and milk mixture. The ideal temperature is around 234°F (112°C). This ensures the sugar is fully dissolved and will result in a creamier consistency. Additionally, opt for a creamy peanut butter rather than a chunky one to avoid any unwanted texture in the final product.

How To Store or Freeze Your Fudge
Allow the peanut butter fudge to cool completely at room temperature before storing. This ensures it sets properly and maintains its delightful texture.
Once cooled, cut the fudge into squares. This makes it easier to grab a piece whenever you crave a sweet treat.
For short-term storage, place the fudge squares in an airtight container. Layer them with parchment paper to prevent sticking. Store at room temperature for up to a week.
If you prefer to keep your dessert fresh for a longer period, refrigerate the airtight container. This will extend its shelf life to about two weeks. Just remember to let the fudge come to room temperature before serving for the best texture.
For freezing, wrap each fudge square individually in plastic wrap. This prevents freezer burn and keeps the pieces from sticking together.
Place the wrapped squares in a freezer-safe bag or container. Label it with the date to keep track of freshness.
When you're ready to enjoy your peanut butter fudge, simply remove the desired number of squares from the freezer. Let them thaw in the refrigerator or at room temperature.
For a quick treat, you can even enjoy the fudge straight from the freezer. The texture will be firmer, but the flavor remains delectable.
Always ensure your storage containers are clean and dry to maintain the quality and taste of your dessert.
How To Reheat Leftovers
Microwave Method:
- Place the peanut butter fudge pieces on a microwave-safe plate.

- Place the peanut butter fudge pieces on a baking sheet lined with parchment paper.

Double Boiler Method:
- Fill the bottom pot of a double boiler with water and bring it to a simmer.
- Place the peanut butter fudge pieces in the top pot.
- Stir gently and continuously until the fudge is warmed through.
- Be careful not to overheat, as this can cause the fudge to become too soft.

- This method is the gentlest and helps maintain the fudge's original texture.
