Step-by-Step Instructions
1. Prepare the Pan
Line an 8×8-inch baking pan with parchment paper or lightly grease it. This ensures the fudge releases easily once set.
2. Heat Sugar and Milk
In a medium saucepan, combine sugar, milk, and butter. Heat over medium heat, stirring frequently until the sugar dissolves and the mixture comes to a boil.
3. Boil to Soft-Ball Stage
Boil the mixture for about 4–5 minutes, stirring constantly, until it reaches a soft-ball stage (235–240°F / 113–115°C) on a candy thermometer. If you don’t have a thermometer, test by dropping a small amount into cold water — it should form a soft, pliable ball.
4. Add Peanut Butter and Vanilla
Remove from heat. Stir in peanut butter, vanilla, and a pinch of salt until smooth and fully combined.
5. Beat the Fudge
Using a wooden spoon or electric mixer, beat the fudge for 2–3 minutes until it thickens slightly and becomes creamy.
6. Pour into Pan
Pour the fudge into the prepared pan and spread evenly with a spatula. If desired, sprinkle chopped peanuts, chocolate drizzle, or sea salt on top.
7. Let Set
Allow fudge to cool at room temperature for at least 2 hours, or until firm. For quicker setting, refrigerate for 30–60 minutes.
8. Cut and Serve
Lift fudge out of pan using parchment paper. Cut into squares and serve. Store leftovers in an airtight container at room temperature or in the fridge for up to 1 week.
