peanut butter fudge ingredients


Here’s what you’ll need to make this easy recipe:

  • 2 cups granulated sugar
  • ½ cup milk
  • 1 teaspoon vanilla extract
  • ¾ cup peanut butter

How to Make Peanut Butter Fudge

Step 1: Prepare Your Dish

Start by lightly spraying an 8×8 inch dish with non-stick cooking spray. This will ensure that your peanut butter fudge doesn’t stick to the pan later on. Set the dish aside for now.

Step 2: Combine Sugar and Milk

In a medium-sized saucepan, stir together the 2 cups of granulated sugar and ½ cup of milk. Place the saucepan over medium-low heat and bring the mixture to a gentle boil. It’s crucial to stir continuously to prevent the sugar from sticking to the pan.

Step 3: Boil for exactly 2 ½ Minutes

Once your mixture is boiling, set a timer for 2 ½ minutes and keep stirring. This short but precise cooking time is essential to achieve the perfect fudge consistency. Be sure to watch the timer closely to avoid overcooking. For best results, follow this timing EXACTLY!

Step 4: Remove From Heat and Add Peanut Butter & Vanilla

After the timer goes off, remove the saucepan from the heat. Now, it’s time to introduce the star of the show – peanut butter! Stir in ¾ cup of peanut butter and 1 teaspoon of vanilla extract until the mixture becomes smooth and velvety. The peanut butter not only adds flavor but also gives the fudge its creamy texture.

Step 5: Pour and Cool

Carefully pour the smooth peanut butter fudge mixture into the prepared dish. Use a spatula to level it out, ensuring it’s evenly distributed. Now, the hardest part – waiting! Allow your peanut butter fudge to cool completely. This will typically take a few hours at room temperature.

Easy Peanut Butter Fudge Storage Instructions

Congratulations! You’ve successfully made a batch of homemade peanut butter fudge. But what if you can’t devour it all at once? Here’s how to store it properly:

  • Room Temperature: If you plan to consume your fudge within a few days, you can store it at room temperature in an airtight container. Make sure to separate layers with parchment paper to prevent sticking.
  • Refrigerator: For longer shelf life, keep your peanut butter fudge in the refrigerator. Again, store it in an airtight container or wrap it tightly with plastic wrap.
  • Freezer: If you want to enjoy your fudge over an extended period, freezing is a great option. Wrap individual pieces in plastic wrap and place them in an airtight container or a zip-top freezer bag. Fudge can be frozen for up to two to three months.

Peanut Butter Fudge Tips and Tricks

Now that you’ve mastered the basics of making peanut butter fudge, let’s explore some handy tips and tricks to elevate your fudge-making game:

1. Use a Candy Thermometer: While this recipe doesn’t require a candy thermometer, using one can help you achieve precise results. The mixture should reach the soft-ball stage, which is around 235-240°F (112-116°C).

2. Creamy or Chunky Peanut Butter: The choice is yours! You can use either creamy or chunky peanut butter based on your preference. Creamy peanut butter will result in a smoother fudge, while chunky will add a delightful texture.

3. Quality Ingredients: Always use fresh and high-quality ingredients. The better your ingredients, the tastier your fudge will be.

4. Don’t Skip the Stirring: Stirring continuously is vital to prevent the sugar from crystallizing and to ensure a smooth, creamy texture.

5. Customize Your Fudge: Get creative with your fudge by adding mix-ins like chocolate chips, chopped nuts, or even swirls of caramel for a unique twist.

6. Slice When Cooled: Wait until your fudge is completely cooled and set before slicing it into squares. A sharp knife dipped in hot water will make the slicing process easier.
