Ingredients

  • 2 c. sugar
  • 2/3 c. milk
  • 1 c. peanut butter
  • 1/2 c. marshmallow whip
  • 1 tsp. vanilla
  • 1 tsp. white Karo syrup
  • 1 tsp. butter

Instructions

  1. Dissolve sugar in milk in a saucepan.
  2. Add Karo syrup and boil to soft ball stage.
  3. Remove from heat and add peanut butter, marshmallow whip, butter, and vanilla.
  4. Beat thoroughly until smooth.
  5. Pour into a greased 8-inch square pan and let set.

Tips & Substitutions

To ensure a smooth texture, make sure to thoroughly dissolve the sugar in the milk before boiling. If you don't have marshmallow whip, you can substitute with equal parts of marshmallow fluff or whipped cream. For a nut-free version, try using sun butter instead of peanut butter. Also, consider adding a pinch of salt to enhance the flavor.

Serving Suggestions

Cut the fudge into small squares for easy serving. It pairs beautifully with a glass of cold milk or a cup of coffee. For a delightful twist, serve it alongside a scoop of vanilla ice cream or crumble it over a slice of cake. You can also gift it as a sweet treat during the holidays or for special occasions.

Storage & Reheating

Store any leftover fudge in an airtight container at room temperature for up to a week. For longer storage, you can refrigerate it, which will keep it fresh for up to two weeks. If you want to enjoy it later, consider freezing it in individual pieces; just wrap each piece in plastic wrap and then place them in a freezer-safe bag.

Frequently Asked Questions

Can I use natural peanut butter instead of regular peanut butter?

Yes, you can use natural peanut butter, but be aware that it may make the fudge slightly less sweet and have a different texture. Natural peanut butter tends to be oilier, so make sure to stir it well before measuring to ensure a consistent mixture.

What is the significance of boiling to the soft ball stage?

Boiling to the soft ball stage is crucial because it determines the fudge's texture. This stage ensures that the sugar solution reaches the right consistency to create a smooth, creamy fudge. Use a candy thermometer or test by dropping a bit of the mixture in cold water; it should form a soft ball when ready.

Can I add other flavors or ingredients to the fudge?

Absolutely! You can customize your fudge by adding ingredients like chocolate chips, chopped nuts, or even swirls of caramel. Flavor extracts such as almond or coconut can also enhance the taste. Be sure to adjust the amount of peanut butter accordingly to maintain the right consistency.
