Old Fashioned Peanut Butter Fudge Ingredients

Substitutions and Additions

PEANUT BUTTER: We’d recommend using regular peanut butter in this recipe. Natural peanut butter tends to have oils that can affect the texture of this recipe. 

TOPPINGS: Add even more peanut buttery flavor by sprinkling peanut butter chips on top of the fudge before it cools. 

How to Make This Old Fashioned Peanut Butter Fudge Recipe

STEP ONE: Start by boiling both sugars, butter, and milk in a pot until it reaches 236°F then immediately stop.

PRO TIP: Make sure you have a good candy thermometer to precisely measure the temperature of the mixture.

STEP TWO: Add in peanut butter and marshmallows and whip until it starts to thicken.

STEP THREE: Pour into a buttered 8x 8-inch pan. 

PRO TIP: You could also line the baking dish with parchment paper or aluminum foil to make it even easier to take out if you’d like to.

STEP FOUR: It takes about one to two hours for the fudge to harden completely. Wait until cooled to room temperature and slice into squares.

PRO TIP: To help cut the fudge after chilling, score a grid on the top of the fudge when it is barely set but still warm.

How to Serve

You won’t want to wait to sink your teeth into this super creamy, peanut butter fudge. Fudge makes a delightful dessert for gift-giving, holiday desserts, or a sweet afternoon treat. Squares of fudge are easy to package up in little cellophane bags for edible gifts and served alongside cookies on a dessert tray. Enjoy a bite of peanut butter fudge with a glass of refreshing iced tea or cup of coffee.

Storage

ON THE COUNTER: This old-fashioned fudge recipe keeps just fine at room temperature and does not need to be refrigerated. If you like it cold, you certainly can keep it in the fridge though — some people love that texture! Just make sure you always store your batch of fudge in an airtight container so it doesn’t dry out. This sweet treat should stay fresh for one to two weeks. But I don’t think fudge has ever lasted in our house for that long. 

IN THE FREEZER: This easy peanut butter fudge recipe freezes well. Store in a covered container or wrapped in plastic wrap and then stored in a freezer bag.

Old Fashioned Peanut Butter Fudge is a rich and creamy homemade peanut butter fudge just like grandma used to make. This easy fudge only takes a handful of simple ingredients and a few minutes of effort to create a dreamy dessert that you can share with friends and family any time of the year. 

Frequently Asked Questions

Could I use marshmallow cream instead of mini marshmallows in this easy recipe? 

This delicious peanut butter fudge recipe will work fine with either mini marshmallows or marshmallow cream.

What causes fudge not to harden? 

In many cases, the sugar, butter, and milk mixture needed to be cooked longer or to a hotter temperature. That’s usually the culprit when fudge doesn’t set. The best way to fix this is to try reheating your fudge mixture by adding a little bit more milk and bringing it slowly back to a boil.

Can this fudge be frozen? 

This peanut butter fudge freezes exceptionally well. Store in an airtight container for up to three months. This is a great option if you are planning to give this as a homemade gift. Make it ahead of time and store it until you are ready to share it.
