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

How to Make 2 Ingredient Peanut Butter Fudge

Empty entire jars of vanilla frosting and peanut butter into a large microwave-safe mixing bowl (photo 1). Place in microwave and heat for about 60 seconds or until melted (photo 2). Mix well until combined (photo 3).

Quickly pour the mixture into a 9×9 pan lined with foil. Allow fudge to set, cut into small squares, and enjoy!

Pro Tips

• 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.
