This is my oldest grandson's favorite fudge. When he visited last time, he asked if I'd made him some, and it took about 10 minutes to put it together for him! Super fast and easy **
1 cup butter (2 sticks) ~ melted
7 oz. marshmallow crème/fluff (usually 1 jar)
18 oz. peanut butter (crunchy is fine, if you want nutty fudge)
1/2 tsp vanilla
1 lb. powdered sugar (start with 3-1/2 cups, adding another 1/4 cup if needed)
Add butter, marshmallow crème, peanut butter and vanilla to bowl of electric mixer. Beating on low, slowly add powdered sugar until everything is well incorporated.
Line a 9x13” pan with foil, extending over the sides, and pat the fudge into it really well ~ I use the dampened back of a spoon to get it into the corners and smooth the top. Chill at least 2 hours. Pull out of pan by the foil tabs. Cut and serve.
NOTE: This is a softer fudge, and should probably be kept in the refrigerator to store.
*** I'll usually cut the recipe in half, and put it into an 8" square pan. The whole square will fit into a freezer baggie then, to store in the refrigerator.
