Ingredients For Peanut Butter Fudge Recipe
Sugar: The primary sweetener that gives the fudge its sweetness.
Milk: Helps to dissolve the sugar and create a creamy texture.
Peanut butter: Adds a rich, nutty flavor and creamy consistency.
Vanilla extract: Enhances the overall flavor with a hint of vanilla.
Butter: Adds richness and helps to create a smooth texture.
Technique Tip for This Recipe
When making peanut butter fudge, it's crucial to ensure that the sugar and milk mixture reaches a proper boil. This step helps dissolve the sugar completely, preventing a grainy texture in your final product. Use a candy thermometer if you have one, aiming for a temperature around 234°F (112°C) for the perfect consistency. Stir constantly to avoid scorching the mixture, and once you remove it from the heat, work quickly to incorporate the peanut butter, vanilla extract, and butter to achieve a smooth, creamy fudge.

How to Store / Freeze This Fudge
Once your peanut butter fudge has cooled and set, cut it into squares and place them in an airtight container. This will keep your fudge fresh and prevent it from drying out.
For added protection, you can wrap each piece of fudge in wax paper or parchment paper before placing them in the container. This is especially useful if you plan to stack the pieces, as it prevents them from sticking together.
Store the container in a cool, dry place at room temperature. Your peanut butter fudge should stay fresh for up to a week this way.
If you want to extend the shelf life, you can refrigerate the fudge. Simply place the airtight container in the fridge, and your fudge will last for up to two weeks. Just remember to let it come to room temperature before serving for the best texture and flavor.
For long-term storage, freezing is an excellent option. Wrap each piece of fudge in plastic wrap or aluminum foil, then place them in a freezer-safe bag or container. This will help prevent freezer burn and maintain the fudge's creamy texture.
When you're ready to enjoy your frozen fudge, transfer the desired amount to the refrigerator and let it thaw overnight. If you're in a hurry, you can also let it sit at room temperature for a few hours.
Always label your containers with the date you made the fudge. This will help you keep track of its freshness and ensure you enjoy it at its best.
Avoid storing your peanut butter fudge near strong-smelling foods like onions or garlic, as it can absorb these odors and affect the taste.
If you notice any changes in texture or an off smell, it's best to discard the fudge to avoid any potential food safety issues.
