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

FAQs

What causes peanut butter fudge not to harden? ›

Conversely, if the cooking time is too brief and there is not enough evaporation, too much water will remain and the fudge will be too soft. A temperature of 112°C to 114°C (234°F to 237°F) must be maintained.

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.

While you ultimately want crystals to form, it's important that they don't form too early. The key to successful, nongrainy fudge is in the cooling, not the cooking. The recipe calls for heating the ingredients to the soft-ball stage, or 234° F, then allowing it to cool undisturbed to approximately 110° F.

If your fudge fails to harden in the fridge, it means that you probably didn't cook it to the right temperature. Fudge is a candy, and that means it is extremely picky about temperature - fudge must be cooked to precisely 237–239 degrees Fahrenheit so that sugar forms the desired consistency when cooled.

Temperature Troubles

The most common culprit behind unset fudge is inaccurate temperature control. If the sugar mixture hasn't reached the correct temperature, your fudge won't set. Ensure you use a reliable candy thermometer and follow temperature guidelines meticulously to achieve the desired consistency.

Undercooked. This fudge was cooked until the temperature reached only108 °C (226 °F). At this temperature, the sugar is not concentrated enough... there is too much leftover water in the syrup and the resulting fudge is soft.

Bring the fudge back to a boil with 1–2 US tbsp (15–30 ml) of cream. If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream.

Why won't my 3 ingredient fudge set? This often happens when the condensed milk and chocolate chip mixture isn't hot enough to start. Everything must be completely melted before it is transferred to the pan to cool.

Combine the sugar, milk, butter and salt. Boil for 5 minutes, stirring constantly. Add the chocolate and stir until melted. Remove from heat and stir in vanilla, nuts and marshmallows until melted; mix well.

How is Mackinac Island fudge made? ›

The team has the process down pat: One person weighs the ingredients—raw chocolate from Germany, sugar from Bay City, and cream and butter—into a copper kettle set over a propane gas burner. The maker constantly stirs with an oak paddle until the sugary mixture reaches a roaring boil, about 16 to 17 minutes.

Fudge Didn't Set

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).

Stir Constantly: Stir the fudge mixture continuously, especially during the melting process, to prevent burning and ensure even cooking. Use Sweetened Condensed Milk: Sweetened condensed milk adds sweetness and creaminess to fudge, creating a smooth texture.

The ingredients for fudge are combined and cooked to 234 degrees, cooled to 110 degrees without stirring, then beaten until creamy. Candy that isn't cooked long enough will end up too soft; overcooking makes fudge crumbly or hard.

The key to creamy, luscious fudge is controlling crystal formation. If the sucrose (table sugar) crystals are small, the fudge will feel creamy and smooth on your tongue. But if the crystals are large, the fudge develops a crumbly, dry, or even coarse texture.

What Happens if You Stir Too Early (or Too Late) 130F is the magical temperature at which you will get tiny creamy-feeling sugar crystals, and if you start stirring before then, the crystals might never form so your fudge won't have the correct creamy fudge texture.
