Peanut Butter Fudge (Microwave Recipe, 4 Ingredients!) (2024)

FAQs

Why didn't my microwave fudge harden? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer.

If your fudge turned out super sticky, or it didn't set as it cooled, it probably never got hot enough. This mistake is super easy to avoid if you use a candy thermometer and cook the fudge to the temperature specified in the recipe (usually between 234 and 239°F).

How can you fix soft fudge? Put it in a microwave safe bowl that is large enough that it won't boil over. Reheat it to the boiling point and cook for about 3 more minutes. Then you can beat some powdered sugar into it if this doesn't make it set.

You can fix it. Just place the fudge mixture back in a saucepan on the stovetop with about 1½ cups of water and slowly melt the fudge to a smooth liquid. Bring the liquid to a boil and then to the soft-ball stage and proceed with your recipe (ie: the cooling and stirring steps).

Once a seed crystal forms, it grows bigger and bigger as the fudge cools. A lot of big crystals in fudge makes it grainy. By letting the fudge cool without stirring, you avoid creating seed crystals.

If the fudge is very soft and slightly chewy then it is possible that it did not quite cook to soft ball stage and next time the mixture should be cooked to a slightly higher temperature (soft ball is 112-116c/235-240F and a sugar or candy thermometer can help).

OPTION 3) Sieve together some powdered sugar and cocoa powder, and gradually work this into your unset fudge until it reaches the consistency of dough, then roll out and cut into squares, or shape into balls and then roll in powdered sugar (roll the balls in icing sugar, not yourself).

As water gradually evaporates, sugar is concentrated and the temperature of the mixture rises above 100°C (212°F). If there is too much evaporation, when the cooking time is too long, there will not be enough water left in the fudge and it will be too hard.

Is there any way to fix fudge that didn't set? ›

To fix it, you can reheat the fudge mixture over low heat and continue cooking until it reaches the proper temperature. Be sure to use a candy thermometer to monitor the temperature accurately. Alternatively, you can try to salvage chewy fudge by mixing it into ice cream or using it as a topping for desserts.

How to thicken your fudge? If your fudge it noticeably thin, you may want to add more chocolate. If you are out of chocolate, you can also add 1/4-1/2 cup of powdered sugar. This, however, can make the fudge very sweet.

Too cooked

This fudge was cooked to a temperature of 118 °C (244 °F). At this temperature, the sugar is too concentrated and there is not enough water left to form syrup around sugar crystals. The result is hard and brittle fudge.

Stir the ingredients to dissolve the sugar until the mixture comes to a boil. If your recipe uses milk, stirring will keep the mixture from curdling. But once it reaches about 236–238 degrees F/113–114 degrees C (the "soft-ball" stage), do not stir it or even shake the pan.

Points to remember

You know it's ready when a small amount of the mixture dropped into a glass of cold water sets into a soft ball that you can lift out with a teaspoon and pinch between your fingers. Turn off the heat and keep stirring for 5 minutes or until the mix starts to thicken a little.
