Peanut Butter Fudge

Eating fudge always brings nostalgic memories of vacation travels flooding in with each bite. It didn’t matter which town my family was visiting there always seemed to be a sweet shop when endless counters of all different flavors of fudge. Peanut Butter Fudge was always one of my favorite variations and once I found out how easy it is to prepare I make it every time during the holidays.

This rich and smooth peanut butter has a sweet taste and almost crumbles as you eat it. It makes the perfect treat and is great for sharing with friends, especially for gifts.



How to Make Peanut Butter Fudge

This simple fudge recipe can be made in under 20 minutes start to finish and even chills quickly in the fridge. With that said the process of making fudge needs to be quick for all the ingredients to set properly. Make sure to prep your ingredients before so you’re ready.

  2. Heat: In a large pot melt the butter and peanut butter together over medium heat, stirring continuously. Bring to a boil and remove from heat.
  3. Mix: Stir in the salt and vanilla until combined and then mix in the powdered sugar until smooth.

Pro Tips for Making Fudge

  • When slicing the fudge coat your knife in a cooking spray so it makes a clean slice through the fudge. Then before making the next slice carefully clean off the blade with a wet paper towel.
  • Make sure to chill the fudge for a minimum of 1 hour so it firms up.
  • To add some extra flavor stir in some marshmallows or chocolate chips before pouring into the prepared dish.

About Aimee Mars

Spending time in the kitchen is a childhood memory that stems as far back as I can remember. The dots connecting those days to recipe development and food photography though, are winding and loopy. Just months after my clothing line in New York City, which was a childhood dream, came to a screeching halt I found myself at home as a new mom with a newborn. Desperately seeking a creative outlet, I began with the familiar and comforting act of cooking. A new passion of recipe development was ignited, and my blog became a place to break bread and to share these recipes with everyone. My family of four and one very convincing dog who loves to beg now enjoy our meals, and scraps, in Charleston.

  2. Hi Aimee,

    I am sharing this recipe on my blog this week! Thanks for the inspiration! laura over at Everyday Edits dot co

  3. I absolutely love peanut butter fudge as it is one of my all time favorites. I remember going to the Sponge Docks in Tarpon Springs as a boy and walking into a local fudge maker’s shop. I was always allowed to sample the cold fudge that he had finished preparing on a slab. While I love the creaminess of the traditional, using peanuts inside for an added crunch is also nice. Great recipe as well!

  4. sharing on the weekend edit. Yum.
