Step 1

Cut out two pieces of parchment paper. One should be big enough to line an 8” x 8” baking dish with enough overhang to lift the fudge out of the dish. The other should be just the right size to sit on top of the fudge.

Step 2

Add a tablespoon of water to the bottom of the 8” x 8” baking dish and line the pan with the larger piece of parchment paper.

Step 3

In a medium-sized microwave-safe bowl, add the unsalted butter and the creamy peanut butter. Heat in the microwave for 60 seconds and then stir. Add the vanilla extract and stir again.

Step 4

Slowly add the powdered sugar, one cup at a time, whilst stirring. Continue to stir until completely combined with no lumps or white streaks.

Step 5

Pour the fudge mixture into the baking dish and spread it out evenly with a spatula. If desired, add red and green M&Ms. Tip: Visualize where you plan to slice the fudge, then add two or three M&Ms onto each piece.

Step 6

Place the smaller piece of parchment paper on top of the fudge to help smooth the top. Leave it in place and put the fudge in the refrigerator to chill for two hours.

Step 7

Remove the fudge from the refrigerator. Remove the top piece of parchment paper and use the overhanging piece to lift the fudge out of the tray.

Step 8

Warm a large, sharp knife under hot water. Dry it and slice the fudge.
