  • 12 ounces peanut butter
  • 1 (7 1/2 ounce) jar Marshmallow Fluff
  • 1 cup chopped walnuts

Instructions

  1. In a saucepan, mix white sugar, light brown sugar, and milk.
  2. Cook for 1 1/2 minutes until the mixture begins to boil.
  3. After it boils, remove from heat and add peanut butter, chopped walnuts, and marshmallow fluff; mix well until smooth.
  4. Pour the mixture into a large 13 x 9 x 2-inch lightly greased pan.
  5. Allow to cool before cutting into squares.

Tips & Substitutions

To ensure a smooth fudge, mix the ingredients thoroughly after adding the peanut butter and marshmallow fluff. If you don't have walnuts, feel free to substitute with pecans or omit them altogether. For a richer flavor, consider using dark brown sugar instead of light. Make sure your pan is well-greased to prevent sticking.

Serving Suggestions

Cut the fudge into bite-sized squares for a delicious treat. It pairs beautifully with a cup of coffee or tea and can be served alongside other desserts like Hash Brown Au Gratin for a delightful spread. For a festive touch, add colorful sprinkles on top before it cools.

Storage & Reheating

Store any leftover fudge in an airtight container at room temperature for up to a week. For longer storage, refrigerate it, where it can last for up to two weeks. If you prefer a softer texture, allow it to come to room temperature before serving.

Frequently Asked Questions

Can I use natural peanut butter for this recipe?

While you can use natural peanut butter, it may alter the texture of the fudge. Natural peanut butter tends to be more oily, which can affect the consistency. For best results, stick to creamy, processed peanut butter, which provides a smoother finish.

What if I want to make this fudge without nuts?

Simply omit the walnuts if you prefer a nut-free version. The fudge will still be deliciously rich and creamy without them. You can also add a pinch of sea salt or a splash of vanilla extract for extra flavor.

How can I make this fudge more festive?

To give your fudge a festive flair, consider adding colorful sprinkles or drizzling melted chocolate on top once it has cooled. You can also incorporate holiday flavors by adding a hint of peppermint extract or using themed cookie cutters to shape the fudge.
