1/2 cup butter
1/2 cup heavy cream
1/2 cup sugar
1/2 cup brown sugar, packed
1/8 teaspoon salt
1 cup chopped pecans
1 teaspoon vanilla extract
2 cups powdered sugar
Line an 8-inch baking pan with foil and coat with cooking spray.
In a large saucepan, bring the butter, heavy cream, granulated sugar, brown sugar, and salt to a boil over medium heat, stirring frequently.
Allow to boil for 5 minutes, stirring constantly, then remove the pan from the heat.
Stir in the pecans and vanilla.
Sift in the powdered sugar, and stir until smooth and well combined. (I REALLY do recommend the sifting. It eliminates any lumps in the powdered sugar and makes the stirring that much easier.)
Spread the mixture into prepared baking dish.
Allow to cool to room temperature.
Lift entire "block" of fudge from the baking pan to cut into 1-inch cubes. (This is where the foil comes in handy and makes cutting perfect little cubes easier.)
Store in air-tight container...if there is any left.
