2 Ingredient Peanut Butter Fudge

Lately my kids have been super into making food for themselves.  Since I don't like them using the stove or oven without supervision quite yet, they've taken to the microwave. And since one of their all-time favorite treats is peanut butter fudge, we found a way for them to cook it up themselves. In the microwave! With just 2 ingredients!

2 Ingredient Microwave Peanut Butter Fudge is easy to make but also creamy, smooth, and delicious. 

This recipe is so simple that you really can't mess up.  Only two ingredients a container of pre-made vanilla frosting and a jar of peanut butter.

Can I Use Any Frosting?

No. Plain vanilla frosting works best in my opinion. You can try other flavors of frosting that might go well with peanut butter, such as a plain chocolate.

Stay away from whipped frostings, as they're the wrong consistency. The fudge won't set properly if you used whipped. I also personally did not care for the flavor of cream cheese frosting with the peanut butter, but the consistency was okay.

What Can I Add to 2 Ingredient Peanut Butter Fudge?

This 2 ingredient peanut butter fudge is delicious on its own. If you'd like to add a little extra flavor or some garnishes on top, sprinkle some of these ideas on top, then gently press in before the fudge sets.

  • Oreo pieces
  • Reese's
  • Peanuts
  • Chopped almonds or peanuts
  • Festive sprinkles
  • Chocolate chips
  • Pretzels

Ingredients

  • 1 can vanilla frosting (16 ounces)
  • 1 jar peanut butter (crunchy or creamy) (18 ounces)

Instructions

  • Empty entire jars of vanilla frosting and peanut butter into a large microwave-safe mixing bowl.
  • Place in microwave and heat for about 60 seconds or until melted. Mix well.
  • Quickly pour the mixture into a 9x9 pan lined with foil.
  • Allow fudge to set, cut into small squares, and enjoy!

Notes

  • Use creamy peanut butter, NOT natural. The natural peanut butter is too runny and will not set properly.
  • Stay away from whipped frostings. The whipped frostings are not the right consistency, and again will not allow the fudge to set properly.
  • Add any garnishes or add-ins right away before it sets or it won't stick.
  • A glass pan is easiest, but any pan lined with foil will work.

    I made this 2 ingredient peanut butter fudge and served at family Thanksgiving. It was a great hit. Everyone couldn't believe it was so easy to make and so delicious. I will make it again, but will try mixing a small amount of chocolate and sprinkles and some nuts..

    Did everyone just use a jar of 16 OZ peanut butter?? There is 16 OZ and then a jar that's about twice the size, but not 18 oz as a single jar...wondering if I need to add another 2 oz of PB to make this come out right???

    Can't beat this for ease, and the texture is amazing! My family loved it, but I would prefer a sweeter taste; less peanut butter-y. Is there anything I could add that wouldn't change the firmness and texture?

      My try experimenting with the brand of frosting. Different brands are sweeter than others.

    How much peanut butter do you have to add to make 18 oz? Can only find 16 oz jar.
    Thank you

      You would need about 20 ounces of peanut butter. Or you could take 2 ounces from the frosting, which would be about 1/4 cup.
