Ingredients

  • 2 cups chunky peanut butter
  • 2 sticks margarine
  • 1 pound confectioners sugar

Instructions

  1. Melt the margarine and chunky peanut butter over low heat until smooth.
  2. Add the confectioners sugar and mix well.
  3. Spread the mixture into a 9-inch square pan.
  4. Allow to cool for 2 hours before cutting into pieces.

Tips & Substitutions

For a smoother texture, ensure the margarine is fully melted before adding the confectioners sugar. If you prefer a less sweet fudge, reduce the sugar by 1/4 cup. You can substitute creamy peanut butter for chunky if desired, but the texture will differ. For added flavor, consider mixing in a pinch of sea salt or vanilla extract.

Serving Suggestions

Cut the fudge into small squares for a rich treat that pairs beautifully with a hot cup of coffee or a cold glass of milk. For a delightful dessert platter, serve alongside Fudgy Mint Cheesecake Bars or Pecan Tassies (Makes 2 Dozen). You can also top the fudge with crushed nuts or chocolate drizzle for added flair.

Storage & Reheating

Store leftover peanut butter fudge in an airtight container at room temperature for up to one week. For longer storage, refrigerate it, where it can last up to three weeks. If you prefer a firmer texture, refrigerate before cutting. To enjoy, simply let it sit at room temperature for a few minutes before serving.

Frequently Asked Questions

Can I use natural peanut butter instead of chunky?

Yes, you can use natural peanut butter, but it may alter the texture and sweetness of the fudge. Natural peanut butter is less sweet and may require adding a bit more sugar or a sweetener to achieve the desired taste.

What if I don't have a 9-inch square pan?

If you don't have a 9-inch square pan, you can use an 8-inch square pan, but the fudge will be thicker and may require a longer cooling time. Alternatively, a rectangular baking dish would also work, just adjust the cutting size accordingly.

Can I add other ingredients to the fudge?

Absolutely! You can mix in chocolate chips, crushed pretzels, or even dried fruit for added texture and flavor. Just be mindful not to overwhelm the base recipe, so keep additional ingredients in moderation.
