Why do we love fudge on vacation?
The rumor is fudge is thought to have been created by accident in America around 1886. The word "fudge" was around long before this delicious candy, and meant to fit together in a clumsy manner. Either way this happy accident has been a staple of coastal tourist towns and holiday celebrations for years.
Fudge became a college fad in the late 19th century when a Vassar college student made about 30 pounds for a senior auction. Then it spread like wildfire among many colleges. Fudge can be a little tricky to make at home, so it became a special indulgence on vacation for folks.
The little shops that sprang up in coastal tourist towns provided a glimpse on how to make fudge as people watched it being made in large pots then spread onto huge marble slabs for forming and cooling. If you would like to read more about this head over to Chowhound.
Helpful tips for making fudge
This peanut butter fudge recipe is quick and easy to make plus it's pretty fool proof. The Instant Pot is perfect for making this as the saute function keeps the temperature pretty even, and brings the mixture to a boil in a flash.
- Ready all required equipment
- Measure ingredients in advance
- Line pan with foil then set aside
- Use only real butter or margarine
- Do not double the recipe
Cooking the fudge
Prepare a 9 x 9 rectangular pan by lining with either foil or parchment paper. I prefer to use foil.
Add to the Instant Pot the butter, brown sugar, and milk. Set the cooker to saute (normal). The butter will melt which will allow you to stir to combine the ingredients.
Stir constantly until the mixture comes to a boil. Once it has come to a boil let it do it's thing for two minutes without stirring.
Finishing the candy
Carefully remove the inner pot with oven mitts and set on a protected surface. This could be your stove top, or another oven mitt. Immediately stir in the vanilla and peanut butter until melted.
Add the confectioners sugar and stir until completely combined and smooth.
Pour the fudge mixture into the prepared pan and smooth the top. Set aside until completely cooled.
Once the fudge has completed cooled remove the fudge from the pan by lifting it up by the foil. Turn over onto a cutting board, and cut into squares by making large vertical and horizontal cuts that will result in roughly 1 ½" inch pieces.
Store in an airtight container, plastic bag, or plastic wrap for up to two weeks. Fudge can be stored on the counter like this or the refrigerator.
Can fudge be frozen?
Yes. Fudge can be frozen, and last a good long time without drying in the freezer. Either wrap the uncut block, or individual pieces in plastic wrap. Place in a freezer bag, date, and store for up to six months.
