This easy microwave chocolate walnut fudge, has only 5 ingredients. The toasted walnuts, and sea salt make it extra special, and it's Mrs. Weasley's recipe. ;)
Toast the walnuts in a dry skillet over medium heat for 3 to 5 minutes, stirring frequently, until fragrant and lightly golden. Remove from heat and set aside. This step is crucial for developing the best flavor in your chocolate walnut fudge.
In a large microwave safe bowl, combine the sweetened condensed milk, chocolate chips, vanilla extract, and sea salt.
Microwave at 50% power for 1 minute. Stir well. Continue microwaving in 1 minute intervals at 50% power, stirring after each interval, until the chocolate is completely melted and the mixture is smooth. This usually takes 3 to 4 intervals total. The chocolate should be glossy and fully combined with the condensed milk.
Stir the toasted walnuts into the melted chocolate mixture until evenly distributed throughout the fudge.
Pour the chocolate fudge into a baking dish lined with parchment paper and spread evenly with a spatula.
Let the fudge set at room temperature for 2 hours, or refrigerate for 1 hour if you're in a hurry. Once set, lift the fudge out of the pan using the parchment paper. Cut into 36 squares (6 rows by 6 rows) with a sharp knife, wiping the knife clean between cuts for neat edges.
