Step 1

In a large microwave-safe bowl, bring together chocolate chips, condensed milk and vanilla extract. Melt in the microwave by microwaving bowl on 50% power for 30 seconds, remove and stir, and then repeating until all chocolate chips are melted.

Step 2

In a medium microwave-safe bowl, bring together peanut butter, butter and salt. Melt in the microwave by microwaving bowl on 50% power for 30 seconds, remove and stir, and then repeating until peanut butter can be stirred easily.

Step 3

Line a 9' x 13' baking dish with parchment paper. Spread chocolate mixture to the bottom of the dish. Place dollops of peanut butter all over the top of chocolate without overlapping.

Step 4

Using a toothpick or a chopstick, spread the peanut butter by moving your chopstick or toothpick horizontally and then vertically.

Step 5

Refrigerate for 4-5 hours, or until fudge is harden.

Step 6

Lift parchment paper and transfer the large piece of fudge onto a cutting board. Remove parchment paper from the bottom of the fudge and discard.

Step 7

Using a sharp knife, slice fudge into 1.5-2-inch squares. If fudge gets stuck on the knife, wipe it with a towel or paper towel rinsed in hot water - this will help you get cleaner cuts of fudge squares. You may have to wipe your knife a couple of times.

Step 8

Serve and enjoy!
