1. Prepare the Baking Pan

• Grease and line: Lightly grease a 9x13-inch (25x30 cm) baking pan or dish with butter or oil, then line with parchment paper. Leave an overhang on the edges to make it easier to lift out the fudge once set.

2. Melt the Butter and Peanut Butter

• Combine ingredients: In a medium saucepan, combine the chopped butter, peanut butter, and vanilla extract over medium heat.

• Stir continuously: Stir until the butter and peanut butter are melted and the mixture is smooth. Heat just until it begins to bubble lightly, then remove from the heat.

• Add whiskey: Stir in the whiskey until well combined, adding a subtle boozy flavor to the fudge.

3. Combine with Powdered Sugar

• Mix quickly: Place the sifted powdered sugar in a large mixing bowl. Pour the warm peanut butter mixture over the powdered sugar.

• Stir until smooth: Working quickly, stir until the mixture is well combined and smooth. The fudge mixture will start to thicken as it cools.

4. Pour and Smooth the Fudge

• Transfer to the pan: Pour the fudge mixture into the prepared baking pan, spreading it evenly.

• Smooth the top: For a neat finish, place a sheet of parchment paper over the fudge and use the flat bottom of a smaller pan or tin to press and smooth the surface. 

5. Add Toppings and Set

• Add chopped peanuts: Press the chopped roasted peanuts gently into the top of the fudge for added crunch and flavor.

• Chill to set: Cover with a piece of parchment paper and refrigerate for 1 hour, or until the fudge is firm.

6. Cut and Serve

• Lift and cut: Use the parchment overhang to lift the fudge out of the pan. Cut into squares and enjoy.

Tips for Success

• Mixing Quickly: The fudge mixture thickens as it cools, so work quickly when stirring in the powdered sugar to ensure a smooth, cohesive texture.

• Storage: Store the fudge in an airtight container in the refrigerator for up to 3 weeks.

• Serving Tip: Let the fudge sit at room temperature for a few minutes before serving to soften slightly.
