How to make Peanut Butter Fudge

First, line a square baking dish with aluminum foil or parchment paper that hangs over the side and spray with nonstick cooking spray.  This will aid in removing the fudge from the pan and peeling the aluminum foil from the fudge.  Take your time doing this, as you want the corner pieces to go all the way to the edges.

Microwave the peanut butter and the butter together until melted and smooth.  Using a wooden spoon, stir in the vanilla extract and powdered sugar in three parts working quickly and stirring constantly.

Finally, pour the mixture into your prepared pan and smooth the top with an offset spatula. Chill in the refrigerator for at least two hours.  Use the aluminum foil to carefully lift the fudge out of the pan.  Peel the aluminum foil from the back and cut it into small squares.

Recipe tips

• Use a regular commercial peanut butter like Skippy or Jif. All-natural peanut butter separates too easily and they do not work well in this fudge recipe. 
• The aluminum foil or parchment should hang over the sides to make it easy to remove the fudge from the pan
• Spray the aluminum foil or parchment paper lightly with nonstick cooking spray for ease of removal.

Storage

• Store the fudge in an airtight container at room temperature for up to two weeks or in your fridge for up to three weeks.
• Place in a freezer bag or wrap tightly in plastic wrap and set inside a sturdy freezer container. Freeze for up to 3 months.

Helpful hints on scoring and cutting fudge.

• Score your fudge with unflavored dental floss. It leaves clean even lines that are barely noticeable in case you make a mistake.
• Have a straight edge with measurements close by so you are making your pieces uniform size.
• Use a sharp thin knife that has been heated under hot water and dried well to slice the fudge.
• Aim for whatever size pieces you and your family like. However, if you are giving the fudge as gifts, you might want to cut in one-inch pieces so you can get more out of a batch.

So if you like peanut butter as much as I do, you are short on time but still have a big heart then put this Easy Fudge Recipe on your to-do list.  You may even find that you have the ingredients already!

See how delicious it looks. I am a huge peanut butter fan, so when it came down to whether or not to make this just days before Christmas it was a resounding yes.  So if time is ticking and you still want a few treats for the neighbors or just in case someone stops by unexpectedly, then this Peanut Butter Fudge Recipe is your baby.  Store in an airtight container on your counter for up to two weeks or in your fridge for up to three weeks.
