How to Make 2-Ingredient Peanut Butter Fudge

Step 1. Line your baking pan with parchment paper or wax paper. I run my parchment paper under water and ring it out, to make it easier to mold.

Step 2. To make the fudge mixture, start by placing creamy peanut butter and frosting in the microwave for one minute.

Step 4. Pour into the lined casserole dish and place in the freezer for 2 hours. Waiting is the hardest part because it’s so tempting to eat the fudge out of the pan!

Step 5. Once the fudge sets, remove it from the pan using the overhanging parchment. Cut into small squares and enjoy.

How to Store Leftover Fudge

Store any leftover fudge in an airtight container at room temperature for 2-3 weeks. You can also refrigerate it but be aware that this could dry it out.

This microwave peanut butter fudge freezes really well. Wrap it tightly with plastic wrap and place in a freezer bag, and it should keep for up to 3 months in your freezer.

Variations and Add-ins

  • Peanut butter: Feel free to use your favorite brand of creamy or crunchy peanut butter. I don’t recommend using natural peanut butter because it can separate and your fudge won’t set as well.
  • Chocolate: Want to make a delicious chocolate peanut butter fudge? Top it with some chocolate chips or chopped peanut butter cups after pouring it into the baking pan.
  • Frosting: We used regular vanilla frosting, but you can use cream cheese frosting if you prefer. For a delicious chocolate fudge twist, you can even make this fudge with chocolate frosting.
  • Toppings: Dust the top of the fudge with a little powdered sugar or cocoa powder. You can also add festive sprinkles, chopped nuts, or crushed Oreos on top before it’s cooled and set.

FAQs

Can I make this fudge without a microwave?

Absolutely! You can heat the peanut butter and frosting together on the stovetop over low heat, stirring constantly until well combined.

How long does it take for the fudge to thaw if I freeze it?

If you’ve stored the fudge in the freezer, let it thaw in the fridge for a few hours or at room temperature for 15-20 minutes before serving.

Can I double the recipe?

You sure can! Just make sure to use a larger dish or two separate pans to accommodate the increased amount of fudge mixture.

      How much sugar, milk and peanut butter do use

      1. Hi Nancy,
        If you go to the recipe card at the end of the post, you can find all that info. There’s also a jump to recipe button at the top of the post if you want to get there quickly. Hope you enjoy it! đŸ™‚

    2. Would a non-dairy milk work in this recipe?

      1. I haven’t tried it but I don’t think it would work as well. It would probably change the texture of the fudge too much.

    3. Kids loved it,so amazing an quick Thankyou so Much****
