Peanut Butter Fudge Ingredients

Substitutions And Additions

PEANUT BUTTER: Any commercial brand of smooth peanut butter will work for this recipe, although you may find that the brand you choose will affect the color of your fudge slightly.

We tested four different brands (JIF, Peter Pan, Skippy, and Reese’s) and found that Peter Pan produced a darker color, JIF was the lightest, and Reese’s had a slight orange hue, but the fudge consistency was the same.

The Peter Pan brand was also slightly sweeter, while the JIF was just a bit saltier.

VANILLA EXTRACT: If you don’t have this in the cupboard, you could use two teaspoons of maple syrup instead in this delicious fudge.

POWDERED SUGAR: This is also known as confectioner’s sugar or icing sugar. In a pinch, you could use six cups of granulated sugar instead in this simple recipe.

M&M’s: These are optional, but we love how they make this amazing fudge look pretty. You could use mini marshmallows, chocolate chips, peanut butter chips, or other small candies if you prefer.

If you are making this another time of year, you can also use different colors of M&M’s too.

How To Make This Peanut Butter Fudge Recipe

This recipe will come together in a flash in the microwave. Just follow our easy instructions below.

STEP ONE: Cut out two pieces of parchment paper. One should be big enough to line an 8×8-inch square baking pan 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 TWO: Add a tablespoon of water to the bottom of the 8×8-inch square pan and line the pan with the larger piece of parchment paper.

Make sure to let the bottom parchment paper hang over the edges of the pan.

STEP THREE: 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 the peanut butter mixture.

STEP FOUR: Add the vanilla extract and stir again.

STEP FIVE: Slowly add the powdered sugar, one cup at a time, whilst stirring. The peanut butter mixture will become stiffer to stir.

Continue to stir until completely combined with no lumps or white streaks.

STEP SIX: Pour the fudge mixture into the baking dish and spread it out evenly with a spatula.

STEP SEVEN: Place the smaller piece of parchment paper on top of the fudge to help smooth the top surface of the fudge.

Leave it in place and put the fudge in the refrigerator to chill for two hours.

STEP EIGHT: Remove the fudge from the refrigerator. Remove the top piece of parchment paper.

Using a sharp kitchen knife, pre-score the size and number of the serving pieces of fudge, but do not cut the fudge until you remove it from the pan.

STEP NINE: Using the over-hang pieces of paper, lift out the fudge and place it on a cutting board.

STEP TEN: Warm a large, sharp knife under hot water. Dry it and slice the fudge into small squares.

STEP ELEVEN (optional): Once the pieces are cut, place 2-3 red and green M&M’s on the top of the fudge for decoration.
