I’ll admit that I’m a skeptic when it comes to recipes that brag about using just a few ingredients, while promising that the finished product actually tastes good. While I love having easy recipes in my back pocket, with minimum prep and clean up, I also know that many times shortcuts just don’t cut it. Those dishes oftentimes feel a little thin, like they’re missing something. They leave me yearning for just a little more somethin’ somethin’.

But somethin’ about this recipe for Foolproof Peanut Butter Fudge, with just two ingredients, had me curious. And with not much to lose in both time and money, I set out to prove myself wrong!


Christmas desserts by Laura Powell

This incredibly easy recipe comes from Laura Powell‘s new book, Christmas Desserts. I first met Laura last summer in Chicago, where we were on a kitchen cooking team together. We seemed to laugh at the same things, question the same things. I liked her. So when she asked me recently if I’d like a copy of her new Christmas book of desserts, I told her that I most certainly would.

This book would make the perfect stocking stuffer. With just 20 easy recipes, Laura’s book gives you plenty of variety without being overwhelming. Of particular interest to my own taste buds were recipes for Eggnog Cookies, Chewy Gingerbread Bars, and White Chocolate Cranberry Orange Bars.

And, oh yeh, this peanut butter fudge that uses only two ingredients.

Ask our kids how suspicious I was of this recipe. (Sorry, Laura – just keeping it real around here!)

When I removed the fudge from the pan, holding onto the foil lining, my doubts started to ease up, though. The peanut butter fudge was nice and firm, yet soft. The knife cut through it like thick butter, with smooth, clean lines. My perfectionist self was loving the thought of sharing these beautiful little cubes on a holiday platter.

But the real test, of course, was in the taste and texture of the peanut butter fudge in my mouth. And you know that I wouldn’t share anything with you that wasn’t good…

Yes, this two-ingredient peanut butter fudge was a hit. We all loved its super creamy texture and peanut butter flavor. And when my parents were visiting us a couple weekends ago, I served some fudge to them without revealing anything about the humble ingredient list. After just one bite, Mom asked me for the recipe. She could not believe that yummy concoction was made from a container of peanut butter and a container of vanilla frosting. I know that some will argue the qualities of this being a true fudge, but I really don’t care. It’s quick. It’s easy. It tastes delicious. It proved me wrong.

  • 1 16.3-oz. container creamy peanut butter, or about 1-3/4 cups
  • 1 1-lb. container vanilla frosting


  • Line a 9″ x 9″ pan with foil and set aside.
  • Add peanut butter and vanilla frosting to a medium sized microwave-safe bowl. Do not stir. Microwave for 1 minute, then stir until combined and completely smooth. Pour into prepared pan and spread evenly. Place in refrigerator until firm. Remove the fudge from the pan using the foil, and then cut fudge into squares.
  • This fudge is very creamy, with a texture that is a bit softer than traditional fudge. It’s oh so good! The fudge freezes well, too. Just place it in an airtight container with layers of fudge separated by wax paper.
