Old Fashioned Peanut Butter Fudge
- Total Time: 20 minutes
- Yield: 10 servings 1x
Description
This old-fashioned peanut butter fudge is rich and creamy, with a perfect balance of sweetness and a hint of molasses flavor.
Ingredients
- 1/2 cup (120 ml) whole milk
- 2 cups (400 g) sugar
- 4 oz (115 g) marshmallow cream
- 1 1/3 cups (320 ml) peanut butter (1 cup Smart Balance brand and 1/3 cup Jif for a darker roasted flavor and hint of molasses)
Instructions
- Line a 9-inch glass oven-proof baking dish with aluminum foil, ensuring it covers the sides for easy removal later.
- In a medium saucepan, pour in the milk followed by the sugar. Stir to combine.
- Place the saucepan over medium-high heat and bring the mixture to a boil. Continue boiling for 3-4 minutes, stirring constantly to prevent burning.
- Remove the saucepan from the heat and immediately stir in the marshmallow cream and peanut butter. Mix until the ingredients are fully combined and the mixture is smooth.
- Quickly pour the fudge mixture into the prepared baking dish, spreading it evenly with a spatula.
- Let the fudge cool at room temperature until set, about 2 hours. For faster setting, you can refrigerate it for about 1 hour.
- Once set, lift the fudge out of the dish using the foil and cut it into squares for serving.
Notes
- For a darker roasted flavor, use Smart Balance brand peanut butter.
- The fudge can be stored in an airtight container at room temperature for up to a week.
- For a firmer texture, refrigerate the fudge before serving.

Frequently Asked Questions
What does the marshmallow cream do in this fudge?
The 4 oz of marshmallow cream is stirred in off the heat along with the peanut butter and acts as a stabilizer — it gives the fudge a smooth, creamy texture and makes it more forgiving to set without needing a candy thermometer.
Why does the recipe blend two types of peanut butter?
The recipe uses 1 cup Smart Balance and 1/3 cup Jif specifically for a deeper, darker roasted flavor with a hint of molasses that Jif contributes. Using either brand alone is fine, but the blend produces a more complex flavor than either by itself. 
How long does this fudge take to set, and how should I store it?
Let the fudge cool at room temperature for about 2 hours, or refrigerate it for about 1 hour if you’re in a hurry — the notes also say refrigerating gives a firmer texture. Once cut into squares, store in an airtight container at room temperature for up to a week.
