Key Ingredients & Substitutions

To make this peanut butter fudge recipe, you’ll need the following ingredients:
- 1 2/3 cups creamy peanut butter
- 3 cups powdered sugar
- 1/2 cup butter
- 1/2 cup evaporated milk
- 1 (7 oz.) jar marshmallow creme
- 1 teaspoon vanilla extract
You can substitute the evaporated milk with whole milk or half-and-half if you prefer. Additionally, you can use granulated sugar instead of powdered sugar, but keep in mind that it may affect the texture of the fudge. When using granulated sugar, it’s essential to grind it in a food processor or blender to make it finer before using it in the recipe, as this will help to create a smoother texture.
Step-by-Step Instructions

1. In a large microwave-safe bowl, combine the peanut butter, butter, and vanilla extract. Microwave on high for 90 seconds, stirring every 30 seconds, until smooth.
2. In a separate large saucepan, combine the powdered sugar, evaporated milk, and marshmallow creme. Place the saucepan over medium heat and cook, stirring constantly, until the sugar has dissolved and the mixture is smooth.
3. Bring the sugar mixture to a boil, then reduce the heat to medium-low and simmer for 5 minutes, or until the mixture reaches 235°F on a candy thermometer.
4. Remove the saucepan from the heat and stir in the peanut butter mixture until well combined.
5. Pour the fudge mixture into a lined or greased 9×13-inch baking dish.
6. Allow the fudge to cool to room temperature, then refrigerate for at least 4 hours or until firm.
7. Cut the fudge into 48 1-inch squares and serve.
For safe storage and reheating, review these cold food storage guidelines before refrigerating the dish. It’s also important to note that when working with sugar and dairy products, it’s crucial to follow safe minimum internal temperatures to prevent foodborne illness.
Expert Chef Tips & Troubleshooting
To prevent the peanut butter fudge from becoming too grainy or crystalline, make sure to melt the sugar and peanut butter mixture slowly and evenly, either in the microwave or on the stovetop. Avoid overheating the mixture, as this can cause the sugar to crystallize. Also, make sure to cool and chill the fudge mixture for at least 4 hours before cutting it, as this will help to set the fudge and prevent it from becoming grainy.
One common mistake to avoid is not stirring the sugar mixture constantly while it’s cooking. This can cause the sugar to burn or crystallize, resulting in a grainy texture. To prevent this, make sure to stir the mixture constantly, especially when it’s reaching the boiling point.
