Ingredients:
- 2 cups (400g) granulated sugar
- 2 tbsp (28g) unsalted butter
- 3 cups (510g) semi-sweet chocolate chips
- 1 jar (7 oz / 198g) marshmallow creme
- 1 tsp (5ml) pure vanilla extract
- 1 cup (115g) chopped walnuts
Instructions:
- Combine the granulated sugar and unsalted butter in a heavy bottomed saucepan over medium heat. Stir constantly until the butter is completely melted and blended with the sugar.
- Bring the mixture to a full rolling boil. Note: A rolling boil is one that doesn't stop bubbling even when you stir it.
- Boil the sugar mixture for exactly five minutes. Set a timer to ensure you don't overcook it into a hard candy.
- Remove the pan from the heat immediately.
- Quickly stir in the semi sweet chocolate chips. Stir until the chips are fully melted and the mixture looks glossy and smooth.
- Stir in the marshmallow creme and vanilla extract. Mix until no white streaks remain and the color is uniform.
- Gently fold in the chopped walnuts. Use a folding motion to ensure the nuts are evenly distributed without deflating the air from the marshmallow.
- Pour the mixture into a greased 8x8 inch baking pan. Smooth the top with a spatula until it's level.
- Let the fudge sit at room temperature for 30 minutes.
- Move the pan to the refrigerator and chill for at least 2 hours. Slice into 1 inch squares using a sharp knife.
