Ingredients You’ll Need for the Best Peanut Butter Fudge
Before you start making your peanut butter fudge, it’s important to gather all the ingredients. Having everything on hand will ensure the process goes smoothly and you’ll get the best results.
Here are the basic ingredients that will give you rich, smooth, and creamy fudge:
Key Ingredients
- Peanut Butter: The star ingredient of this recipe. Use smooth peanut butter for the creamiest texture. If you prefer a more textured fudge, you can use crunchy peanut butter, but for a smooth consistency, smooth peanut butter works best.
- Sweetened Condensed Milk: This is essential for a creamy texture and sweetness. Sweetened condensed milk is a thick, syrupy milk product that adds richness and helps the fudge set.
- Butter: Adding butter to the mixture not only enhances the flavor but also contributes to the smooth, melt-in-your-mouth texture. Use unsalted butter for better control over the salt content.
- Powdered Sugar: Powdered sugar, also known as confectioners’ sugar, is the perfect sugar for fudge recipes. It dissolves easily, giving your fudge the smooth texture you expect.
- Vanilla Extract: A small amount of vanilla extract adds depth to the flavor and enhances the peanut butter’s richness.

Optional Ingredients for Custom Fudge Flavors
If you want to get a little creative, there are several optional ingredients that can add a twist to your classic peanut butter fudge. Here are a few suggestions:
- Chocolate Chips: Add semi-sweet, milk, or dark chocolate chips to the fudge mixture for a peanut butter chocolate fudge.
- Chopped Peanuts: If you love a little extra crunch, chop up some salted peanuts and fold them into the fudge mixture for added texture.
- Marshmallow Fluff: For an even fluffier, lighter texture, you can add a bit of marshmallow fluff to the fudge base.
- Sea Salt: A light sprinkling of sea salt on top of your fudge will provide a delicious sweet-salty contrast.
- Coconut Flakes: For a tropical twist, add sweetened coconut flakes to the mix.
Step-by-Step Instructions to Make Peanut Butter Fudge
Making peanut butter fudge is an easy process that anyone can follow. The following step-by-step instructions will guide you from start to finish, ensuring a smooth, rich fudge with just the right texture.
Step 1: Prepare Your Pan
To prevent the fudge from sticking and to make it easier to remove, you’ll need to line your baking pan.
- Line an 8×8-inch baking pan with parchment paper or aluminum foil. Be sure to leave a slight overhang so you can easily lift the fudge out once it has cooled and set.
- Set the pan aside.
Step 2: Melt the Butter and Peanut Butter
This step creates the base for your fudge and brings the key ingredients together.
- Place ½ cup of butter and 1 cup of peanut butter into a medium saucepan.
- Heat the mixture over low heat, stirring occasionally to prevent the butter or peanut butter from burning.
- Stir continuously until the butter and peanut butter are completely melted and fully combined. The mixture should be smooth and creamy.

Step 3: Add Sweetened Condensed Milk
Sweetened condensed milk adds the creamy texture and sweetness that makes peanut butter fudge so irresistible.
- Pour 1 can (14 oz) of sweetened condensed milk into the saucepan with the melted butter and peanut butter.
- Stir the mixture over low heat until everything is fully combined and smooth.

Step 4: Mix in Powdered Sugar and Vanilla
Now that you’ve got a creamy base, it’s time to add the powdered sugar and vanilla extract to bring everything together.
- Gradually sift in 3 cups of powdered sugar. The powdered sugar dissolves quickly and helps thicken the mixture, giving your fudge that perfect consistency.
- Stir the mixture well to ensure the sugar is fully incorporated.
- Add 1 teaspoon of vanilla extract and mix it in to enhance the flavor of the fudge.

Step 5: Chill the Fudge
Once the fudge mixture is ready, it’s time to let it set and cool in the refrigerator.
- Pour the fudge mixture into the prepared baking pan, spreading it evenly with a spatula.
- Place the pan in the refrigerator and let the fudge chill for at least 2-3 hours, or until the fudge has set and is firm to the touch.
- The longer you let the fudge chill, the firmer and easier it will be to cut.
Step 6: Cut and Serve
Once the fudge is completely chilled and firm, it’s time to cut and enjoy!
- Remove the fudge from the pan using the overhanging parchment paper or foil.
- Use a sharp knife to cut the fudge into small squares or rectangles, depending on your preference.
- Serve immediately, or store the fudge in an airtight container at room temperature.

Tips for Perfect Peanut Butter Fudge
To ensure your peanut butter fudge turns out perfectly every time, keep the following tips in mind:
1. Use High-Quality Ingredients
The quality of your ingredients will directly affect the taste and texture of your fudge. Opt for high-quality peanut butter, sweetened condensed milk, and butter for the best results.
2. Let the Fudge Set Completely
Be patient and allow the fudge to set completely in the refrigerator. Cutting the fudge too soon will cause it to crumble and fall apart.
3. Stir Consistently Over Low Heat
When melting the butter and peanut butter together, make sure to keep the heat on low and stir consistently. If the mixture gets too hot, it can alter the texture of the fudge.
4. Customize the Flavor
Feel free to add your own personal twist to the recipe. Mix in some chocolate chips for peanut butter chocolate fudge, or add some chopped peanuts for extra crunch. You can even top the fudge with a sprinkle of sea salt for a sweet and salty flavor.
5. Use Room Temperature Ingredients
If possible, bring your butter and peanut butter to room temperature before starting the recipe. This will help them melt together more easily and ensure a smoother texture in your fudge.
FAQ
Can I use natural peanut butter for this recipe?
While you can use natural peanut butter, it’s not ideal for this fudge recipe. Natural peanut butter contains more oil, which can make the fudge too runny and affect its texture. For the smoothest results, stick with regular, processed peanut butter.
Why is my peanut butter fudge too soft?
If your fudge is too soft, it might not have chilled long enough. Be sure to refrigerate the fudge for at least 2-3 hours to set properly. Additionally, using too much sweetened condensed milk or not enough powdered sugar can also result in a softer consistency.
Can I add chocolate to my peanut butter fudge?
Yes, you can! Adding chocolate is a great way to change up the flavor. You can swirl in melted chocolate or fold in chocolate chips to create a peanut butter chocolate fudge combo that’s both creamy and decadent.
How do I store peanut butter fudge?
Store your peanut butter fudge in an airtight container at room temperature for up to a week. If you’d like to keep it fresh longer, refrigerate it or freeze it. To freeze, wrap it in wax paper and store in an airtight container for up to 2 months. Let it thaw at room temperature before serving.
